Oh, I don't know yet.

One of the things I'm hoping to be able to do is to find the analog of Brownian motion in space.

In other words, Brownian motion was seeing down to the level of an effect from individual molecules.

In the case of space, most of the things we see about space so far, just everything seems continuous.

Brownian motion had been discovered in the 1830s, and it was only identified what it was the result of by Smoluchowski and Einstein at the beginning of the 20th century.

And dark matter was discovered, that phenomenon was discovered 100 years ago.

The rotation curves of galaxies don't follow the luminous matter.

That was discovered 100 years ago.

And I think that I wouldn't be surprised if there isn't an effect

that we already know about that is kind of the analog of Brownian motion that reveals the discreteness of space.

And in fact, we're beginning to have some guesses.

We have some evidence that black hole mergers work differently when there's discrete space.

And there may be things that you can see in gravitational wave signatures and things.

associated with the discreteness of space.

But this is kind of, for me, it's kind of interesting to see this sort of recapitulation of the history of physics, where people vehemently say, you know, matter is continuous.

Electromagnetic field is continuous.

And turns out it isn't true.

And then they say space is continuous.

But so, you know, entropy is the number of states of the system consistent with some constraint.

And
