And some physicists think that time subjectively is a qualia just like color is.

Color doesn't exist in the outside world.

It's purely a feature of how the brain tags and processes information.

And for subjective time, it might also be a qualia just like color.

Absolutely.

Well, well, the brain researchers know that the pace at which time passes between when you're young and when you're old is very different.

And it all has to do with novel things being presented to your senses.

When there are a lot of novel things being presented to your senses, your brain spends a lot of time processing each now event because there are no patterns that it really has in memory to to tell it what's going on.

But as you get older, you've seen just about everything you're going to see.

And so everything that you see is something that the brain has already processed.

And so it doesn't spend very much time belaboring over why is that chair red and stuff like that.

So the pace of time is slower for adults.

who are not processing very much novel information and very fast for young people who are processing a lot of novel inputs all the time.

It's pretty well understood, yeah, in terms of neurophysiology.

That's sort of an accepted paradigm at this point.

It doesn't seem that the brain really cares about time in an absolute sense.

It does care about the memories that it stored for any given chunk of daily experiences that are novel.

It's this novelty aspect that the brain really gloms onto and really essentially determines the sense of how time is passing for you.

Yes.

And that's called entropy.
