It’s Monday again, and though it is not raining down by me, I’m all but certain that it’s raining somewhere right now, so one could say “it’s raining again” without fear of being entirely wrong. No matter how you might want to cut up spacetime based on “planes” of “simultaneity”, there is sure to be somewhere in the universe where it is raining now.
Actually, if the universe is infinite in spatial extent, one could probably prove that it is a mathematical certainty that it’s raining somewhere, since there are‒as far as we can tell‒only a finite number* of possible quantum states in any given region of spacetime, and some of these include rain. Indeed, even if it were not raining on Earth, anywhere, in some given instant (an unlikely eventuality), the fact is that rain can happen in many places in many forms. I’m led to understand that it sometimes rains neon in the atmosphere of Jupiter.
So, perhaps the song by Supertramp shouldn’t have been It’s Raining Again, but should have been It’s Raining Still.
I don’t know. Maybe that wouldn’t suit the rhythm of the song. Then again, it always was a song where the sentiments expressed in the lyrics didn’t quite match the upbeat character of the tune. This was probably deliberate on the part of the band.
Oh, in case anyone was wondering, the reason there was no post on Saturday was that, indeed, we did not work in the office on Saturday. We didn’t work out of the office, either, as far as I know. Well, I know I didn’t work, so even if they worked, we did not work, so I guess I’m right there.
I did a fair amount of walking on Saturday, and nearly as much on Sunday, though Saturday’s walk was more interesting. I walked in a “park” along a canal in south Florida, and found myself well down into Dade County before I found an exit from the park area that took me to a road on which I could get something to quench my thirst and a place to which to call an Uber (they have a hard time picking one up in a park alongside a canal). I had walked about seven and a half miles, and I could tell I was getting a bit too much sun**, though my feet and ankles and knees seemed to be holding up okay.
On Sunday I went for another walk, during which I had enough sunscreen. That was because on Sunday I took my walk solely for the sake of walking, unlike Saturday, on which I had a specific purpose, and my longer walk began on a whim after that purpose was achieved.
It wasn’t an interesting or noteworthy purpose, by the way. I’m just not discussing it because it cannot have any bearing for anyone but me.
Let’s see, is there anything else going on that’s worth discussing? Well, of course, there are things going on in the world, and in the universe, and so on, all the time, and probably many of them are worth discussing to someone, or would be, even if no one knows they are happening. But, of course, pretty much anything that happens, no matter how locally momentous, is historically trivial, let alone cosmically trivial.
Probably there aren’t many things that aren’t cosmically trivial. I suppose if inflationary cosmology is real and it started at some locus in spacetime, then that would not have been trivial. But if there is eternal inflation, there’s a real question as to whether it started at all.
Of course, even then, with eternal inflation, the local drop of the inflaton field down to the vacuum state (or a pseudo-vacuum state) here in our bubble universe‒leading to the formation of our universe, all its matter and energy, and possibly the configuration of our natural laws and constants‒would seem to be significant.
But that would only be significant to us, the creatures in this bubble universe. On the scale of the cosmos overall, it would be just one bubble universe formation in an endless sea of such bubble universes, each one no more striking than the cavitation bubbles that form and then collapse in water that’s starting to boil. Indeed, if our universe is such that an eventual recollapse will happen, i.e., a “Big Crunch”***, then we really are a lot like a cavitation bubble.
I guess this has been a slightly odd way to start the week‒which is unfortunate, given that today’s date is an even number (24) not an odd one. But I don’t think I’ve ever claimed not to be an odd person. I think I’ve known that I was different and a bit peculiar‒perhaps more than “a bit”‒since I was very young. That’s okay in and of itself. If most people are “normal”, why the hell would anyone want to be normal?
With that, I wish you all an abnormally good day and week, and if you’re in the US, I hope you have a good holiday coming up, and that you are anticipating it with eagerness.
*It’s big, don’t be mistaken. But the biggest finite number you can think of‒ever‒is no closer to infinity than is the number 1. So, in a universe that’s infinite in spatial extent, all possible finite configurations will be instantiated somewhere‒indeed, they will be instantiated an infinite number of times.
**I hadn’t planned on such a long walk, so I was not prepared in that sense.
***Our best information right now seems to indicate that we are not going to recollapse, but that we will continue to expand, at an ever-increasing rate. I suppose that would make us more akin to a bubble that fully forms and expands in boiling water, escaping from the liquid into the air above. Such bubbles are no more important than the cavitation bubbles, though. They’re merely different.

It sure feels like eternal inflation looking at price tags for the last several years.
Heh. Yeah.
