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.
