Since “Evian” is “naive” spelled backwards, are its drinkers wise and sophisticated?

(This post has nothing to do with the headline, just in case you’re wondering.)

I’m not quite ready to reveal the truth about yesterday’s blog post; I’m kind of hoping that someone who doesn’t usually comment might throw their hat into the ring* and make a guess.  I don’t know who such a person might be, but it would be nice to have ever more comments.

For this post, though, I will reveal that it is being written on my smartphone.  I didn’t bring along the lapcom because I was very fatigued by the end of the day yesterday.  This was mainly mental fatigue, but that translates into low physical energy as well, since it’s the functions of the brain that largely determine the movement of the body.

Which is not meant to imply that the brain is not part of the body; it very much is.  I am no dualist in any sense of the word.  The brain is an organ, and like all other organs, it has its attributes and vulnerabilities and dysfunctions.  Trust me on that last score.

Or don’t trust me, that’s entirely up to you.  I wouldn’t be inclined to try to cajole someone into trusting me.  I’m not a huge fan of presumptive trust anymore than of giving someone presumptive “respect”.  To me, respect, like trust, has to be earned, through the outcomes of interactions, and it can never really, reasonably, be complete.

Everything is always a calculated risk, including trust, even if the calculations are…not very rigorous or conscious, and even if people claim to have it absolutely.  Those who make such claims are wrong or lying or both.  One cannot even trust oneself absolutely.  Trust me on that.  Ha ha.

Anyway…

That’s just some typical nonsense or bullshit or whatever you want to call it from me.  I don’t have any intention here‒not one of which I am aware‒other than just “to write another blog post”.  How’s that for a positive, beneficial purpose or undertaking?  How’s that for something to try to give oneself a sense of purpose or meaning or belonging?  It’s pretty unimpressive, really.

As for belonging, in particular, it’s a fairly laughable notion for me.  I don’t belong anywhere.  Maybe no one does.  Maybe the very notion of “belonging” in the social sense is and has always been a cognitive and emotional illusion.

Like individual atoms that exist within water molecules in the ocean, a person can technically be part of something bigger without any actual real involvement in that bigger thing, and without losing any nature of separateness.

Any electron in the outer portion of any atom, or anywhere else, is just an electron and‒barring highly energetic interactions‒is going to remain an electron** forever, as far as we can tell.  And it is literally identical in characteristics to every other electron that exists, and they are all entirely fungible, just like the individual cents in your electronically recorded and maintained bank account.

Of course, people, despite being composed of countless numbers of such tiny, fungible particles, are not fungible.  They are too complicated, there are too many ways to put electrons and quarks together to make a person for any two to have even a nanoscopically tiny chance to be identical in all pertinent senses.

Okay, I don’t know what point, if any, I’m trying to make here.  Probably there is none.  Or if there is, it is probably some desperate, quietly terrified attempt to connect somehow with some kindred spirit(s) somewhere.  However, I am getting weirder and weirder all the time, or so it seems to me, so it seems ever more unlikely that kindred spirits exist for me, if they ever did.

Like Melkor, I’m looking to find something or someone in the Void, but alas, it is just…void.  And my thoughts continue to be unlike those of my brethren, and, like Melkor, I become ever more dispirited and spiteful, though at least I’m not trying to conquer or destroy Arda.  I went through that phase back when I was a preteen and teenager.

I’m not saying I was necessarily wrong when I recognized that people are absolutely shit at trying to create and run civilization well.  I just don’t think it’s probably worth the effort to correct things, because it would be a neverending effort.

Oh, well.  That’s enough of my spewing words for the moment.  There seem to be brush fires down in south Florida‒we can all smell the smoke‒but it seems unlikely that they will contribute much to the destruction of current human society.

Is that good?  Is it bad?

I don’t know.

I hope you have a good day.

*Would such a hat become invisible?  Would it, if it were strong enough, gain the power to sense and dominate the wearers of all the other rings?  Would it inevitably become evil?

**The same cannot be said for muons, let alone taus, the two higher mass “species” in the electron family.  They are unstable and rapidly decay to smaller particles, but they have the same charge and spin as an electron.  Electrons, on the other hand, appear to be at some manner of ground state; they are too “light” to decay into anything smaller spontaneously, and any changes they do undergo cannot violate the conservation of charge, so they are limited.

Cosmic. Way out. I can relate.

Well, here we are beginning another Monday, and I’m writing this post—again—on the mini lapcom.

I say “again” not because I am writing this very post for a second (or more) time, nor because the last post I did was written on the lapcom, because it was not.  I mean “again” in the sense that last Monday I wrote my blog post on the lapcom.  I also did so on Tuesday and on Wednesday last week, but I cannot yet say that I will do so tomorrow and the next day.  I won’t even say “barring the unforeseen”, because I can rather easily imagine, and therefore foresee, situations in which I will not write those blog posts on the lapcom.

Of course, I also cannot predict whether, like last week, I will write Thursday’s and Friday’s posts on the smartphone.  It’s not that unlikely, but I don’t know ahead of time whether I will write them on the smartphone or the lapcom.  I could make predictions, but I think anything deviating terribly far from 50/50 would probably be very much a rectally sourced prediction.

I will say, though, that if I do write blog posts the rest of the days this week—which will include Saturday, alas—I will almost certainly write them either on the lapcom or the smartphone.  How’s that for a bold prediction?  It’s not a certainty, of course, but then again, pretty much nothing is.  It’s getting into the high 90 percentiles though, I’d guess.  I’m not skilled enough at probability/decision theory to get much finer in my estimation than that.

Anyway, that was about 250 words of utterly pointless drivel, wasn’t it?  It’s quite odd how much and how quickly I can write about more or less nothing of significance.  Mind you, from a certain point of view, nothing is really of significance.  Also nothing is of significance.  I mean two different things by those two different uses of the same words.

The first means that there is almost nothing in the universe that, in itself, is significant (cosmically speaking, of course—on different scales, significance has different requirements).  No individual, localized thing or fact can matter much on the largest scales.  On the other hand, nothing—the vacuum, absence, whatever you want to call it—is significant.  This partly refers to the fact that the universe appears to be expanding at an accelerated rate, and this seems to be due to the vacuum energy, the energy of “empty” space.  A uniform energy density in space creates a negative pressure, which creates “negative gravity” in a sense, and that drives an expansion of spacetime.

The nature of this vacuum energy, or cosmological constant, is definitely significant in that it will determine, almost solely as far as we can tell, the future fate of the universe.

Of course, the term “vacuum” may be somewhat misleading given its ordinary usage (quite apart from when one refers to the household appliance).  The vacuum is never really “empty” despite what the usual meaning of the word is.  It’s full of all sorts of quantum fields as well as the gravitational field that is spacetime itself.  The vacuum is just when these fields are in their lowest possible states/energy levels*.

There’s also the famous Higgs Field, which actually is one of the quantum fields, but it is interesting in that it is a scalar field, meaning that it has magnitude at every point but not direction (like a map demonstrating local temperatures on Earth’s surface, as opposed to one detailing the wind, which will have magnitude and direction).

If this seems a peculiar distinction to you, think of the electromagnetic field, which has both magnitude and direction at every point.  It’s actually a little more complex even than just that, because of course, electricity and magnetism are two aspects of the electromagnetic field, but each one of them is a vector field (with magnitude and direction) which interacts with the other, so the combination of them is something more involved.

Also, when energies are high enough (changing the way the Higgs field interacts with other fields), the weak nuclear force and the electromagnetic force turn out to be part of the same thing, called the electroweak force.  And, of course, there is the question of whether all the fields are really just aspects of some “higher” field or structure.

This would be some form of “unified field theory” (not to be confused with GUTs, or “grand unified theories”, which are less grand and less unified than unified field theories).  Of course, we don’t know that there is a unified field.  There may not be.  There may just be a minimum number of fields that cannot be further reduced.

If M-theory (AKA string theory) is correct, then yes, there is a unified form from which all fields derive their character thanks to the shapes and resonances of their vibrations in high-dimensional spaces.  On the other hand, other versions of quantum gravity such as “loop quantum gravity” leave gravity (AKA spacetime itself) as a separate kind of field, composed of tiny, tiny parts (the “loops”) knitted together.

At least some versions of this theory have been disconfirmed, however, because it predicts a very, very slight difference in the speed of travel of electromagnetic waves depending on wavelength, and light from extremely distant quasars has been tested and found to be uniform in arrival time (based on variability in the quasars and specific catastrophic events, if memory serves) from wavelength the wavelength, even to tiny parts in billions of light years traveled.

Okay, well, that’s surely enough trivia for anyone early on a Monday morning.  I wish I didn’t have to work today, but then again, I wish I didn’t feel like I have to do anything.  But I do feel that way.  I guess it’s probably better than being inert.  Without a goal or goals—terminal, instrumental, or otherwise—there is no action.

You can call it a “drive” instead of a “goal” if you prefer.  That may be a more accurate term, since nature doesn’t act in a teleological way (outside of thinking minds) but instead generates drives/urges/impulses, some of which lead to increased genetic reproduction and some of which lead in the other direction.  Over time, the former are the ones that tend to accumulate, for what are probably obvious reasons.

Enough.  I already said it was enough, didn’t I?  Anyway, I hope you all have a good day.  And remember, if you tend to come to this blog via other social media, you can subscribe to it using your email, and then you’ll get emails sharing every new post with you directly.

Take care.

*There is also a thing called a false vacuum.  Spacetime itself could be in such a state, if the vacuum energy is capable of tunneling to an even lower energy level than the one at which it currently resides.  This would not be a good thing for the current inhabitants of the universe, but at least they would never know it if the drop-down happened, because everything that currently exists would be erased at the speed of light.  The universe as a whole would even be affected, but it wouldn’t be endangered per se.

Should you give a fig about a freight train’s Newtons?

It’s Saturday, April 25th, in 2026 AD/CE.  There are only 7 shopping months until Newtonmas (Other holidays are available).

Anyway, I’m very groggy and tired today, though at least I am (for the moment) in slightly less pain than yesterday.  It still sucks, but now it’s more of a neutron star kind of sucking rather than a full scale black hole.

Not that either of those two stellar remnants can be said to “suck” in any atypical way, with respect to gravity.  It is true that the gravitation at the surface of a neutron star is extremely high (to say nothing of the “surface” of a black hole).  But that’s just because everything is so compact, and you can get much closer to the center of gravity than you would be able to do with more spread-out astronomical bodies made of more typical matter.

But, to reiterate a perhaps overused example, if the sun were suddenly (and without any other phenomena that would complicate the picture) to collapse* into a neutron star or even a black hole of the same mass, the Earth’s orbit would not change at all.

There’s no special “supergravity” or whatever some people imagine there might be due to black holes or neutron stars.  It’s just ordinary gravity with a large mass in a small region.  From farther away than the former surface of whatever collapsed into it, the gravity of a neutron star or a black hole is literally indistinguishable from that of the celestial object that became the black hole or neutron star (if it did not lose any mass in its collapse to the latter state, which in reality they almost always do).

How the hell did I get on that subject?  I don’t know.  I guess I’ll see it while editing.

I’m a little out of it this morning, because I took half a Benadryl last night in addition to my other, more typical stuff.  I don’t usually take Benadryl on a work night, but groggy and unpleasant quasi-consciousness that at least helps me to be unconscious is better than not being able even to get to sleep or stay that way for long and being groggy because of that rather than the side effects of an antihistamine.

Something like that, anyway; I’m not sure I made that very clear.

I’ve just now become briefly distracted because a redirected freight train just went by on the track in front of me (going south on the usually-northbound side of the tracks, something for which there were no doubt legitimate reasons, but which still feels quite wrong).  This happens occasionally, and I’m sure the process that leads up to it is somewhat interesting, at least from a certain point of view.

It’s definitely an event that happens only because something has gone wrong somewhere.  The tracks for commuter trains, like the course over which they run, are not really meant for heavy freight trains, so they can’t let them use them very often.  And it was heavy, I’m sure of that. There were numerous tank cars and box cars and all sorts of similar cars carrying potentially heavy stuff.  Even the train’s whistle as it approached was a different, lower pitched sound and had a more somber timbre (sombre timber?) than the usual Tri rail whistle.

I already was pretty sure it wasn’t a regular train when the nearby gates went down to stop traffic, because there’s no scheduled Tri rail train going in either direction at even close to that time on a Saturday.  If it were a behind-schedule train, it would have to have been the first train of the day going south, and it would be quite off its schedule indeed.  Trains only come every hour on the weekend.

I almost wrote “every hour on the hour” there, just for the “sound” of it, but of course it’s not feasible to have a commuter train arrive every hour on the hour at every train station unless the stations are an hour’s traveling distance apart.  That would be one hell of a commute, and not in a good way.

Anyway, I think that’s enough nonsense for today.  I still don’t feel good.  My legs and hips are still channeling low-level but constant DC current (or so it feels), and I am having more and more trouble seeing any point to continuing to try to style my way though all this.  It’s been more than 20 years and things are not improving overall.

It would be more tolerable if I had other people and reasons and points in my daily life, but I don’t, not really.  The comments here below this blog constitute the majority of my socialization, not counting work interactions (which are a different kind of thing, though related).

I’m so bloody tired.

Anyway, have a good weekend if you can.  For goodness sake, cherish the people you love and who love you, especially if you’re lucky enough to be with them every day.  And remember, when in doubt, don’t ask yourself “What would Newton do?”.  Unless you’re a scientist, that is, in which case, yeah, Newton was a decent role model.

Otherwise, he was a terribly unpleasant, vindictive, and spiteful man (and here I thought it impossible for me to admire him more than I already did).  He is reported to have laughed only once in his life, when someone asked him what was the point of studying Euclid.

I sympathize with Newton there.  That is an idiotic question for anyone who is stuck living in and making their way through three-dimensional, locally Euclidean space.

Mind you, when things like black holes and neutron stars are involved, you need to go beyond Euclid, but you can’t readily go beyond Euclid if you’ve never gotten to Euclid***.

*There’s no known process by which this could happen, by the way, so don’t worry about it.  Also, you don’t need to worry about encountering spherical cows or frictionless surfaces**.

**Though I’ve long thought that “Frictionless Cows” might be a good name for a band.

***You don’t need to read Euclid’s actual book to study Euclidean geometry, any more than you need to read Newton’s Principia Mathematica to learn Newtonian physics.  But it’s worth giving them each a tip of the hat in passing, at least, for they are among humanity’s greatest works.

If you can look into the seeds of time, and blog which grain will grow and which will not

Hello, and also, good morning.

What to write about, what to write about‒that is the question today.  Of course, “to be or not to be” is always the question as well, as was recognized by Camus in The Myth of Sisyphus.  If I recall, he arrives at the conclusion that the titular rock-rolling protagonist must be “happy” despite the patent and constant pointlessness and absurdity of his existence.

That goes along with the whole recognition of the absurdity of life itself that is central to the existentialism movement.  Still, it’s hard for me to “imagine Sisyphus happy”, unless he was a true Bodhisattva or had been thoroughly lobotomized by Zeus (or whoever it was that had doomed him to his…well, his doom).

It can help, I guess, to think about the vast scale of the cosmos in space and time (and any other dimensionality that might apply) and also about the incredibly minute scale of the cosmos, the fundamental quantum fields (and whatever gravity ultimately is) interacting from the Planck scale on up.  It helps keep things in perspective.

Of course, even given the scales of the cosmos*, there’s another, almost sort of Buddhist/Taoist notion that notes that each individual‒each particle even‒always exists at the nexus of two “light cones”, existing in an ever-moving now.  These are 4-dimensional cones, by the way, but it’s okay to reduce things by one dimension if you will.  It makes them easier to visualize.

Your (or anyone’s) past light cone is the outer boundary of all influences that can possibly have had any effect upon you at the present moment‒those influences that could have reached you at the speed of light or more slowly.  Similarly, one’s future light cone encompasses all those things that could possibly be influenced by things at the present location at or below the speed of light.

Any motion within the light cones‒the only motion that anything within spacetime can execute, as far as we know‒is called timelike motion.  Any motion that would require going outside a light cone is considered “spacelike” motion, and is not allowed by relativity.  This is not merely because of the speed of light, it’s because the speed of light is defined by the speed of causality.  Causes cannot travel faster or have effects beyond the speed of causality.  This is a bit tautological, I know, but it nevertheless simply must be true.

So each individual’s experience, each individual process, sits at the moving balance point of a future light cone and a past light cone, crossing at the moving present, tracing out a “timelike” path in spacetime.  Of course, individual creatures are not individual particles, and so their overall spacetime path would resemble the final line produced by a sketcher going over and over a particular path to make the curve the artist desires.

If one could look at the structure of a human in spacetime, like the Tralfamadorians of Slaughterhouse Five, but one could also trace even the spacetime paths of individual “particles”**, a human life would be a sort of higher-dimensional braid in spacetime, surrounded by a haze of incoming and outgoing quantum entities, most of which will be locally bound and interacting, and so will be moving at a net velocity lower than the speed of light.

I’m assuming you don’t eat your food or drink your water or breathe your air or (shudder) sweat or excrete at near light speed.

Imagine what the inside of a mere proton or neutron might look like if one were able to see it as a rendered, four-dimensional model in fine detail!  If you think it wouldn’t be that interesting because it’s so wee, think again.

Remember, only the tiniest fraction of the “rest mass” of a nucleon comes from the mass of the three “net” quarks in it (two up, one down or two down, one up depending on whether it’s a proton or neutron).  Almost all the rest of its mass is the energy of the interactions between these three quarks:  all the gluons exchanged, all the virtual quark/anti-quark pairs popping into existence, mediated by that famous strong force and its weird*** “asymptotic freedom”.

Bringing this back around, I guess my point was merely to note that everyone and everything is pointless from the perspective of the laws of nature and the spacetime scale of the cosmos, but when you learn about those things‒the cosmos at large and small levels‒you are at least familiarizing yourself with those vast workings, and you are in a sense taking part of them into yourself.  That’s kind of a cool thought.

But don’t take too much of it into yourself!  For, much as would happen to someone who stuffed all the information about Graham’s number into one head, if you do you will become a black hole.  Now, it may be possible to survive becoming a black hole, but I don’t recommend betting on that pony.

*I wrote a post on Iterations of Zero about how it might be useful for people to consider the cosmic perspective as contrasting with their prosaic concerns.  I don’t remember how good it was, but here’s the link, in case you want to read it and give any feedback you like.

**I use this word for want of a better term that everyone would recognize and that would be succinct.  I think we need such a different term, because a lot of the perceived so-called weirdness and mystery of quantum mechanics comes from trying to use inaccurate terms that originated in times before we understood things as well as we now do.  Quanta are not little “particles” that sometimes act like waves, nor are they little waves that sometimes act like particles (though that’s slightly more accurate).  They are entities unto themselves, and the ways they behave are all always consistent with that nature.  They don’t sometimes act like one thing and at other times act like another.  They all, always, act like what they are.

***Except it’s not weird, really.  Those of us who are surprised by it?  We are the weird ones.  Quantum chromodynamics has always done exactly what it still does, since long before any life at all existed in this universe.  To quote Yudkowsky again, “Since the beginning not one unusual thing has ever happened.”

Our wills and fates do so contrary run, that our devices still are overthrown; Our blogs are ours, their ends none of our own.

Hello and good morning.  It’s Thursday, the 26th of February in 2026, a date that’s only very slightly interesting whether you write it as 2-26-2026 or 26-2-2026.  The fact that you have repeated 2s and repeated 26s is somewhat entertaining, but the zero throws potential symmetries off, making it not nearly as much fun as it could conceivably be.  It’s a shame, really.  I suppose you could write it as 26-02-2026 and rescue a bit of symmetry, but that feels like reaching.  It’s not quite symmetrical anyway, unless one is writing in base-26 or higher.  No, wait, even that wouldn’t work.

I don’t know about what I’m going to write this morning.  That in itself, of course, is nothing unusual.  But I don’t feel that I have much to say about anything at the moment.  I don’t want to get into my depression and ASD and anxiety and chronic pain and insomnia and just general moribund state, because I’m sure no one wants to hear about it anymore, and in any case, there seems to be no way anyone can do anything about it that’s useful, which makes it all the more frustrating.  Writing about it certainly hasn’t cured or even improved my state much, if at all.

Anyway, as I said the other day, you have been put on notice.  Unless you just started reading my blog for the first time yesterday, you’ve no right to act fucking surprised no matter what happens.

Okay, that’s that out of the way.

Now, let’s see, what should I write today?  I could discuss some topics in science, especially physics, though I also have literal, legally recognized expertise in biology, and I know a lot about quite a few other branches of science as well.  This is because I have always been curious about how the world, the universe, actually and literally works on the largest and on the most fundamental scales.

I mean, yes, humans also have their rules and laws and social mores and antisocial morays and all that nonsense, but if you step back even a bit, you can see nearly all human behavior encapsulated by basic primatology.  If you know how the various monkeys and gibbons and gorillas and chimpanzees behave‒especially their commonalities‒human behavior almost always fits right in.  It’s usually not even very atypical.

That doesn’t make the specifics of behavior very easily predictable in any given case, necessarily; then again, we understand an awful lot about the weather and the climate, but the specifics of tomorrow’s weather are tough to predict precisely and accurately, let alone next week’s weather.  Nevertheless, the physics of longer term climate effects of certain kinds of atmospheric gases is almost trivial.

Anyway, humans are too annoying to be very interesting, except in special circumstances.  In this, they are perhaps a bit like cockroaches.  From the point of view of a scientist who studies them, they can be interesting, and from just the right angle and with the right detachment, they can even be beautiful (or some of them can).  But overall, they are merely large masses of highly redundant little skitterers, just doing their shit-eating and reproducing and infesting almost every possible location.

Which type of creature did I mean to describe just now?  See if you can figure it out.

Of course, on closer scales, cognitive neuroscience and neurodevelopment and related stuff, such as “neural” networks, “deep” learning, and other such areas are fascinating.  One thing interesting about them is how all the things that brains and computers and so on are and do are implicit in the laws of physics‒clearly they are some of the things that stuff in the universe can do‒and yet, for all we know, they have only ever happened here, just this once in all the vast and possibly infinite cosmos*.

And for all we can tell, given the human proclivity to plan about 20 Planck units ahead and then after that trust to luck, this could be the only place they occur, and their time will not continue much longer, certainly not on a cosmic scale.

I could be wrong about that…except in the sense that, since I am stating it merely as one of the possibilities, I am not actually wrong at all.  Even if humans do survive into cosmic time scales and become cosmically significant, it will still not be easily debatable that it could have happened that humans would go extinct and would fail to go anywhere but Earth.

Of course, depending on the question of determinism, I suppose one could say that if humans (or their descendants) become cosmically significant then there literally was nothing else that could have happened, at least as seen from outside, at the “end”.

On the other hand, if Everettian quantum mechanics is the best description of the fundamental nature of reality, then in some sense, every quantum possibility actually happens “somewhere” in the universal quantum wave function, though those variations may not include all conceivably possible human outcomes.

Some things that seem as though they should be possible may simply never happen to occur (or occur to happen?) anywhere in the possible states of the universe.  That feels as though it should be unlikely, given how many possible states can be locally evolved in the quantum wave function, but I don’t think we know enough to be sure.

Okay, well, I vaguely hope that this has been mildly interesting and perhaps thought provoking.  It would be enjoyable to get more feedback and thoughts, but I don’t have a very large readership, and only a certain small percentage of people ever seem to interact with written material in any case, so I’m probably lucky to get the feedback that I get.

*With the inescapable caveat that, if the universe is spatially and/or temporally infinite, and if as it seems there are only a finite number of differentiable quantum states in any given region of spacetime (the upper limit of which is defined by the surface area of an event horizon the size of the given region) then every local thing that happens, and all possible variations thereof, “happen” an infinite number of times.  But given that all these regions are more or less absolutely physically distinct and incapable of “communicating” one with another, they can be considered isolated instances in a “multiverse” rather than parts of the same “local universe”.

Are gravity and frivolity truly opposites?

It’s Wednesday morning (not quite five o’clock yet) and it is February 25th.  There are only ten more shopping months until Newtonmas*.

For those of you who don’t know (and as a reminder for those of you who do know) Isaac Newton was born on December 25th, 1642 (AD**).  Now, there is a parenthetical here:  Newton was born on December 25th by the Julian*** calendar, which was the one used in England at the time of his birth.  By the Gregorian**** calendar, Newton would have been born in early January of 1643.

This might seem to imply that December 25th nowadays shouldn’t be considered Newtonmas, but of course, it’s a closer fit than celebrating the birth of Jesus on that day; supposedly, biblical scholars have found that Jesus was probably born in the summer or something.  As with many things, “The Church” appropriated the popular holidays celebrating the winter solstice and grafted Christian religious significance onto it.

There’s nothing particularly bad about that.  All these holidays and divisions of the year are fairly arbitrary (though celebrating solstices and equinoxes is common enough in multiple cultures, which makes sense because these are objective events in any given year that can be noticed by any culture that is paying attention).

The length of a year is a concrete, empirical fact, as is the length of a day and the length of a lunar orbit around the Earth.  None of them are straightforward multiples of each other, unfortunately‒they are waves that are not harmonically associated with each other.

I don’t know how long it would take for their “waves” to come back into some primordial alignment and “start over”, but it’s probably moot, because the length of a day and of a lunar orbit and of the orbit of the Earth are changing slowly.  The moon, for instance, is moving steadily (but very slowly) away from the Earth over time, and so its time of orbit is increasing (since things that orbit farther away orbit more slowly).

I think Kepler’s third law was/is that the period of a planet’s orbit around the sun is proportional to the 3/2 power of the length of the semimajor axis of its orbit.  I’m not sure if that exact power holds up on the scale of, say, the lunar orbit, but the laws of gravity are as universal as anything we know.  Indeed, there are materials that are opaque to light, but as far as we know, there are none that are opaque to gravity.  Gravity is nevertheless constrained by the geometry of spacetime, so orbits will always slow down at a faster rate than the distance from the center around which a mass orbits increases.

The inability of anything we know of to block gravity is one thing that makes me take seriously the notion that, at some level, there could be more than three spatial dimensions.  If gravity is not confined to three dimensions then nothing that is so confined could stop it; it would merely flow around any obstacle (maybe gravity waves, for instance, can even diffract around matter and energy, though that might not imply higher dimensions).

This is related, indirectly, to the fact that it is impossible to tie a knot in a string in 4 or higher spatial dimensions.

By the way, having those extra spatial dimensions curled up tiny, as is usually presented in depictions of the notions of string theory, is not the only way for them to exist and be undetected.  If most of the forces in the world we know‒the electromagnetic, the strong force, the weak force, and the various matter-related quantum fields‒are constrained to a 3-brane because their strings are “open-ended”, then we could live in a 3-brane (in which all other forces, including matter, are confined) nested in a higher-dimensional “bulk”.  Gravity could be conveyed by a “looped” string, which could pass through the 3-brane, interacting but not being confined to it.  This could also explain the comparative weakness of the gravitational force and might even explain dark matter (and why it is so difficult to detect).

This sounds extremely promising, maybe, but there are issues and hurdles, not the least that strings and higher spatial dimensions are very difficult to detect, if they exist.  Also, it’s very hard to pin down all the implications mathematically in a useful way.

I remember one lunch break when I was still in medical practice when I tried to see if I could work out mathematically if “dark matter” could be explained by a relatively nearby, parallel brane-universe (it would probably be more than one, but one was difficult enough) whose gravity spills over into and overlaps the gravity of our brane-universe.

Here’s a sort of reproduction of some of the scribbling I did then:

Unfortunately, though I could visualize what I was considering and get an intuitive feel for what the math would be like, my precise mathematical skills were just not up to the task of sorting it out rigorously.  Also, of course, lunch was not long enough, and I had many other things on my mind.  Anyway, findings like the “bullet cluster” provide some fairly strong evidence that “dark matter” is something physical within our three dimensions of space.

Okay, that’s enough for today.  I’ve managed not to talk about my depression and stress and self-destructive urges/wishes (except just now, of course), so I hope you’re pleased to have had those things cloaked from you today.

Take care.

*Working out the exact number of days, I think I figured that it was 302.  December 25th is 7 days before New Years, so it’s day number 358 in the (non-leap) year.  And today is the 25th day of the second month, and January has 31 days, so today is day 56 of the year.  And, of course, 358 – 56 = 302.

**Why not my usual “AD or CE?”  Because at the time, in England, it was just “anno domini”.

***Named for Julius Caesar, though as far as I know, he had no more to do with actually formulating that calendar than he had with the invention of the 7th month.  As far as we know, he wasn’t even born by the then-existing version of Cesarian section, which was more or less always fatal to the mother, and his mother lived well beyond his birth.

****Named after Pope Gregory XIII, also known (by me) as Pope Gregory Peccary*****.  He did not formulate the newer calendar, but supposedly he at least commissioned the Vatican astronomers to create it when it had become obvious that the Julian calendar was not quite tracking the actual year but was overshooting over a long period of time.  So, the Gregorian calendar is better named than the Julian calendar, or so it seems to me.

Tomorrow, and tomorrow, and tomorrow, blogs in this petty pace from day to day, to the last syllable of recorded time

Hello and good morning.  It’s Thursday, in case you didn’t already know.  Though, if you’re reading this on some day other than Thursday, then I guess it’s not Thursday for you.

You could think of it as us being on sort of parallel time streams—and indeed, we each carry our own “proper time” around with us, according to Relativity.  And while communication is possible between those timelines, it is communication in one direction only.  I can send messages to you, where and when you are now reading this, but you cannot send messages back to me.

Wait, wait, I hear you say*, you can communicate back to me in my parallel time, because you can comment on the post below (there’s only one person who does this with any regularity, but sure, it’s possible for you to comment, in principle).  So it’s not one-directional communication.

Ah, but that’s where I’m being esoterically precise here.  You cannot communicate back to me where and when I am now.  You can only communicate with some “future” point, something quite a bit down the line from where and when I am as I write this.  And I cannot then communicate with the you that is writing back to me, but only to some future state of you.

Okay, well, duh, you say**, that’s just how time works.

That only seems unremarkable to you because it’s all you’ve ever known, and you’re adapted to it—personally and evolutionarily.  But if you step back, so to speak, it can seem quite remarkable.

Special Relativity demonstrates that space and time are not separate but are intertwined, and space and time bleed into one another depending upon relative motion—indeed, within the event horizon of a black hole, it appears that space and time are flipped ninety degrees (as though along an axis at 45 degrees to those of space and time) so to speak, so that space becomes time, which is part of why you can never get out of the black hole—you cannot reverse time, but must move forward to its end at the singularity, if such a thing exists, which is probably not the case.

So, why does time work differently than space?  After all, If I live on a street parallel to yours, I can cross to your street by any of a number of cross-streets, cut through back yards, follow alleyways, etc., in more or less any direction, and I can return in a similar fashion.

Imagine, though, if it worked the following way.  I start at my address—let’s imagine it’s number 13*** for the moment—and want to go to your street.  But I can only go by routes that are at higher address numbers than my address.  And then, when I want to return to my street I have to go down (or would that be up?) the numbers on your street, to take a cross-street (or whatever) that’s even farther from my house.

So, say I crossed to your street right after number 17, where a cross-street exists.  And say the numbers on your street line up with those on my street, just for simplicity’s sake****.  Luckily, your house is at number 19 on your street, so I can reach it.  I could never go back to number 17 on your street, let alone number 13.

But when I want to leave your place, I can only head toward higher numbers, so I can’t go back to the cross street near 17.  I have to go down to, say, the street past number 23.  But even once I get to my street, I can’t go back to my house!  I must head in the direction of higher numbers.

I can only get back to my house if my street goes all the way around the world and comes back to my house from the other direction, and I suspect that it doesn’t do that.  I’m stuck farther down my own street, homeless now, because I cannot reach my address.  And it’s not as though you can take me in, because I cannot go back to your address, either, and if you leave your house to meet me, you will be in the same predicament in which I languish.

That’s sort of how time seems to work.  Unlike the three spatial dimensions, we cannot simply choose our direction, change our mind and our course, go back to where we came from or even just go around and around the block (which may or may not be a stupid thing to do—see yesterday’s post).  Why is time different?  The laws of physics appear to be locally time symmetric as they are space symmetric.  In other words, they work the same backwards and forwards.  But macroscopically, time is directional.

I’ve speculated a bit on this over at Iterations of Zero.  I’ll try to link to the pertinent blog post(s).  Some of that speculation compares the directionality of time that we all experience to the directionality of space that exists here on the surface of the Earth.

Wait, you say, what do you mean “the directionality of space”?  (You do love to interrupt, it seems.)  Well, think about it.  When you’re on the Earth, the directions forward/backward and left/right (or any other non-parallel axes you might choose along the surface, such as north/south and east/west) are freely navigable.  You can go in any direction or combination of directions along them, barring local obstacles.  But the same cannot be said for up/down.  It’s much harder to go up than to go left or forward.  And if you lose support beneath your feet, you will be unable to avoid going down.

Perhaps, as has been speculated by others with greater expertise than mine, the “Big Bang” provides or entails a local state that creates a local directionality to time, but far enough away from that “event”, time will become just as non-directional as any spatial dimension.

This is the way it works with the dimensions of 3D space:  when you’re far enough away from a local “event”, such as the surface of the Earth, the dimensions are all freely navigable.  But there’s not too much to do there, and it seems that life and complexity are likely to emerge only where these local gradients—whether in space or in time or both—exist, doing their part to provide the “free energy” which is required by things like life.

Anyway, that’s my random set of thoughts for this Thursday.  I hope you have a good day.  As for me, I continue to follow the local directionality of my metaphorical space; in other words, I continue to trend downward.  I do not perceive any other available direction for me.

The moving finger writes, and having writ, now must edit

This is it:  my last blog post of 2025 (barring some truly unexpected circumstances).  I will probably be writing a post tomorrow, because I think we’re going to be working tomorrow, despite the fact that it will be New Year’s Day, and a stunningly large fraction of the people of the world will be hung over or otherwise exhausted from ringing in the New Year.

I suspect New Year’s Eve/Day is the most widely celebrated holiday in the world, far surpassing the numbers who celebrate any mere religious holiday.  Since the world in general uses the same “Gregorian”* calendar, it’s a rare commonality for the human race, and worth celebrating.

If only they could work on finding more things in common, since after all, they have almost everything actually in common with each other.  And yet, they focus on trivial cultural or superficial differences and battle viciously over them, as if they were fighting truly alien beings.  Talk about your narcissism of small differences.

Humans are so stupid.  The more of them there are, the stupider, somehow, as though the lowest common denominator tends always to dominate the dynamics.  It’s like Tommy Lee Jones’s character said in Men In Black:  a person is smart, but people are dumb, panicky, dangerous animals, and you know it.

That isn’t always the case, obviously.  Humans have accomplished great things in large groups, interacting with mutual exchange to mutual benefit (or not so mutual benefit), but that probably only happens in rarefied circumstances, discovered or arranged by luck or by the skill of one or a few who are cleverer than average, and sustained thanks to a form of natural selection.

Because of the sheer power of such organizations of people, those rare few types of interactions can endure for tremendous lengths of time and be astonishingly effective and broadly prevalent.  This can distract one from the fact that the ideas were so singular and ingenious.

Money, for instance, has been invented more than once, but it’s a relatively low-hanging and particularly nutritious fruit, allowing as it does for the far more efficient exchange of goods and services to (ideally) mutual benefit.  Of course, commerce can be cheated and can thereby become nonproductive or even counterproductive, especially if one or a few entities obtain disproportionate wealth and power.  This sort of selection for detrimental equilibria happens in the world of biology as well.

Imagine a football game in which, every time one team scores, that team gains an extra player and the other team loses one.  Once one side takes the lead, they’re likely to keep it and increase it, making them ever more likely to maintain their dominance.  It can make for a pretty boring and not very productive game.  Such a situation is worth avoiding, even if you happen to be on the winning team.

Written language is, of course, the single most important human invention‒more important than even the invention of language itself, though that was a necessary prerequisite, so the argument could be made that it is more important or at least more fundamental.  Thankfully, language is a different type of thing than money, so it’s not as easy to game it to secure an unreasonable advantage for any individual or group.

There is, of course, an often-used attempted strategy of discouraging or preventing literacy in some groups or one sex (always the same one, it seems) to keep them from gaining the power that written language can impart, but it can be harder to keep those systems in place than for a monopoly to maintain its economic advantage.

Still, even written language isn’t automatically self-protective.  It’s possible for misinformation and disinformation to spread and even prosper, at least for a time (such situations tend to self-destruct), and it can do terrible damage, much as mutations in somatic DNA can lead to cell dysfunction, cell death, and sometimes cancer.

Analogous things can happen to whole civilizations as well, and they have happened many times, but that’s no reason to blame language or learning.  One doesn’t prevent cancer by eliminating DNA itself or by killing the host organism (that does eliminate the cancer, but in an unsatisfying way).  Only better, more thorough thinking and language, the equivalent of DNA proofreading, can do that without catastrophe.

And I, by writing this post, try to contribute to the good language, the useful or at least interesting language, in the world.  I suspect I will continue to do so as the next year begins.  I hope you enjoy whatever celebrations you have in store.

*Though Pope Gregory the Whatever Number was merely the one who commissioned it.  Astronomers and mathematicians actually did the work.  We have some scientifically literate Popes nowadays, at least, and a Belgian priest was among the first to do rigorous mathematics using Einstein’s new field equations (though Friedman got there a little earlier, his work was apparently not as convincing) to demonstrate that the universe could not be static** based upon them.

**Leading Einstein to introduce Λ (lambda), the cosmological constant.  He later called this his biggest blunder (supposedly) but it turned out to be a useful and term and concept in describing the apparent evolution of the universe as we know it now.  Like Planck before him, even Einstein’s fudges*** were deeply insightful and useful.

***Speaking of Einstein, I recently got an email from my old med school alumni association with the subject line “You are responsible for Einstein’s success”.  To which I so wanted to reply, “I know, right?  But did he mention me in any of his papers or even throw me a word of thanks (in German or otherwise) in his acceptance speech when he got his Nobel Prize for demonstrating that light comes in ‘packets’ which we now call photons?  No!  Ungrateful bastard.”

Happy Boxing Day, everyone.

For those of you in the US who don’t have much interaction with Great Britain or Canada (or the “antipodes”, where I think the day is also “celebrated”), Boxing Day is the official name for the day after Christmas, and since Christmas was yesterday, today is Boxing Day.  QED.

There is, no doubt, a thorough and accurate explanation for why this day is called Boxing Day, but I have not yet encountered it, despite occasional half-assed searches.  I also, honestly, don’t care very much.  I have a vague set of notions for possible explanations, existing in a sort of quantum superposition/probability cloud in my head, and that’s good enough for me.

On the other hand, if anyone out there knows the definitive, accurate, appropriately cited and replicated explanation for the source of the term Boxing Day…just keep it to yourself.  I’m not interested in reading any comments about it.

I am also not interested in reading any comments about Christmas, but I hope those of you who celebrate that holiday had a very lovely day, and enjoyed it in the best possible way with the best possible company.

By “best possible” please don’t take me to refer to some idealized, perfect*, eutopian** day.  I mean, the best possible day you could have given the circumstances of all the people and events in your life and around you.  I don’t expect it was without any unpleasantness or drama or minor irritations.  At the very least, most of us have to use the toilet several times a day, and those who don’t are generally worse off, not better off, than those who do.

But if you got to spend the day (or a significant chunk of it) with at least one person you love and who hopefully loves you, then you have at least some reason to think of it as a good day.  I did not have a good day, but hey, this is me, right?  When do I ever have a good day?

The next big holiday coming up is New Year.  Of course, if the universe overall is a closed loop of time (I have no real reason to suspect that it is, but no strong reason to be convinced that it is not) then this year is not new, nor is it old, it is just fixed.  From within any kind of deterministic spacetime, loop or otherwise, it can feel as though time has passed, but as Einstein pointed out, this would be an illusion (albeit a persistent one).

If things are nondeterministic, then all bets are off with respect to whether time is an illusion or not.  But please, don’t fall for the notion that the facts of quantum mechanics mean that the universe is non-deterministic.  They can mean that, depending on the truth underlying the mathematical descriptions, but quantum mechanics can be just as deterministic‒in a slightly more complicated way‒as Newtonian or Einsteinian classical physics.  Two examples are “superdeterminism” and the Everettian, many-worlds description of quantum mechanics.  There are probably others.

The point being, if the universe is deterministic, then each moment, each year, each Planck time is in a way permanent and “eternal”.  Each event is not only implied in the prior state of the universe, but it is also implied in the future state of the universe.

Some might complain that this would imply that there is no such thing as free will.  I think you are correct.  But so what?  Your will is patently less free than you imagine even in simpler, more straightforward terms.  Can you quickly drink a fifth of Wild Turkey 151 on an empty stomach (with no regurgitation) and choose not to become intoxicated (and possibly dead)?  Can you choose just not to feel tired after being awake for 36 hours?  Can you choose not to feel acute or chronic pain?  If you can do that last thing, I’d be interested in knowing how, so feel free to put that in the comments, but don’t waste my time with nonsense, please.

Anyway, as I like to say, I either have free will or I don’t, but I don’t have any choice in the matter.

It’s a bit like when people say absurd things such as “I wouldn’t want to live in a world without a God”.  My response, usually internal, to such statements is, “I don’t recall being given a choice about which kind of universe I would live in.  Did I miss some prenatal, preconceptual meeting where people were given the various options regarding into which universe they would be born?”

Anyway, it is whatever it is.  In a certain sense, it can of course be useful to consider what the nature of reality most truly and completely is, so we can navigate it in the best available way.  But in another sense, the ability to learn about a deterministic universe is just baked in.  And like everything else, it is permanent, albeit not in the usual, prosaic sense of enduring through time unchanging, since time itself is one of the permanent things.  Does this imply some “meta-time”***?  Not necessarily, but it could in principle.

I don’t think we know enough about the deep roots of reality to do more than speculate about such things.  The speculation can be fun, though, and occasionally it can briefly distract one from the unbearable shittiness of being.  Alas, that distraction never lasts for long; mine is fading rapidly even now, and I don’t feel like writing or even breathing any more.  I can’t do much about the latter process without causing a big to-do, but the writing I can stop any…

*Whatever that even means.

**This is not a typo or a misunderstanding or misspelling.  This is my (apparent) neologism for a truly and realistically ideal place.  The word “utopia” means essentially “no place”, highlighting the fact that such a place does not exist, even potentially.  Whereas my term uses the prefix “eu-” which means “true or good or well” as in eukaryote or eugenics or my middle name “Eugene”.

***This term has nothing to do with Facebook or Instagram or whatever else to which Z*ckerberg has tried to arrogate the term “meta”.

“And, to SLEEP, you must slumber in just such a bed.”

Well, it’s f*cking Saturday, and I’m going in the to f*cking office to f*cking work, because it’s not challenging enough for me to recover my limited mental equilibrium when I have two days off, so I should try to do it with one as often as possible.  Oh, and the one day I supposedly still have to take off is the day I have to do all my laundry, which means I have to go into the other part of the house and, more often than not, deal with their overly energetic and poorly trained dog‒and it’s a big dog.

I’m not afraid of dogs.  I like dogs, even very large ones.  But I have little sympathy for dogs that have not been trained, and who act like they’re still teething or something.  If it were my dog, I could rapidly train it out of the habit of putting its moronic jaws around peoples’ forearms, and it and I and others would be happier overall.

Maybe next time I’ll go out with suntan lotion or even pepper spray all over my arms, so it gets an unpleasant mouthful if it tries.

Honestly, sometimes I’m tempted just to slip it a few chunks of the rat bait/poison that I have.  It’s not the neurotoxin one, which is supposedly less harmful to people and pets than to rats.  It’s the super-coumadin, blood “thinning”, anticoagulant one.  To be honest, though, I would probably not be willing under nearly any circumstance to poison a dog, since the agency of such a creature is limited and its poor behavior is largely due to the humans in its life.

And yes, of course I have a big, multi-pound bag of rat poison.  Who knows, I might get peckish at some point and want it as a snack.  The holidays are upon us, after all, and it can be so hard to stay on a diet at this time of year.

Anyway, that’s just one possible nosh that I have for potential last meals.  I even have a couple of emptied out fiber capsules that I’ve refilled with broken glass pieces.  They would actually go nicely with the previously mentioned snack, wouldn’t they?  Like salted caramel, the two components could really enhance each other.  You might even call it synergy.

Enough about such tempting treats.  The point is, I’m going to the office today.  Then I’m heading back to the house.  Then I’ll be trying to rest if I can for the remainder of the weekend, though when I think of my own mind, I am inescapably reminded of Boromir describing Mordor:

That works pretty well to describe my very annoying brain/body.  I cannot seem to sleep very long, and I never feel like I sleep “all the way” if you will.  I am always somehow on yellow alert; I don’t know why.  It’s exhausting.  There are plain few upsides or effective distractions, and almost never any relief.

I don’t even know what I’m writing about right now, really.  I just feel a general, free-floating hostility and even hatred for most things in existence.  Sometimes I just want to wipe out the whole universe.  It can be done rather easily, at least from a certain perspective.

Incidentally, creating a new local source of the hypothetical inflaton field would probably not do the trick, assuming that inflationary cosmology is correct.  Most of the mathematical solutions to that possible situation indicate that, such a field would initiate a new, rapid, inflationarily expanding “universe”, but from the perspective of our universe the created bubble would just plop through and out of spacetime.  I haven’t done the math myself‒I am not adequately trained to do it at this time‒but I have this from more than one fairly reputable and reliable source, including people who actually do have the necessary expertise.

I’ve previously discussed vacuum collapse; if one could figure out how to trigger that‒assuming it is possible‒one could literally wipe out everything in the current universe.  Though, of course, it would take a long time, since it could only happen at the speed of light, so really, you’d only be wiping out everything in your future light cone.  There may be no way to destroy the universe that doesn’t effectively take a limitless time to accomplish.

On the other hand, when I spin around, it’s possible to view that action as the universe spinning around me while I’m stationary.  There are legitimate reasons why we don’t tend to think of it this way, but it’s a perspective that can be taken.

From that sort of perspective, when one dies (from one’s own point of view at least) the entire universe ceases to exist.  It’s very simple and thorough!  Of course, if there is an afterlife, that plan would fail, and one would be forced to go back to the drawing board.  But I’ve never encountered even borderline intriguing evidence or argument that might indicate an afterlife exists, unless you count things like a Poincare recurrence*.

So there is at least one reasonably reliable and plausibly achievable way to destroy the universe, from my point of view.  And the good thing about that is, from other points of view, the universe would still exist, and this would be no more contradictory than the fact that someone falling through the event horizon of a large enough black hole wouldn’t even notice it happening, but those far away would see the faller as never even quite reaching the event horizon.

Anyway, that theoretical stuff isn’t really very interesting for present purposes.  What matters is, at the very least, I can destroy the universe in a sense, if I so desire.  And every day it seems to become more and more tempting to do so.  This world is just so disgusting so often, and it’s not just humans that meet that description.

Ah, well.  Try to have a good day if you can for as long as the universe does exist.  After that, you’re on your own.

*Or the possibility of quantum immortality in the context of Everettian quantum mechanics.  But the various other possible alternate versions of me in such a theoretical quantum multiverse are not “me” even now, from my point of view‒not exactly, anyway, not in any sense that I can experience.  So future possible subsets of the wave function of the universe that contain randomly immortal versions of me are not worth taking into account, and they are vanishingly rare**.

**Though I suppose, as time goes by and all mortal things die, the quantum wavefunction of the universe might come to be dominated by such versions of…well, everyone.  None, however, would be able to interact with each other as far as I can see.
