Andrew invoked quite a bit of advanced mathematics, but that math has yet to be borne out in experiment.

And so his asking, has an experiment been borne out?

The answer is no experiment has yet shown that the universe is in fact a full block.

So we will see.

One thing that people think might help is if we could somehow send information faster than light.

through perhaps quantum entanglement or some kind of quantum teleportation.

It is at the moment absolutely technically impossible.

But some people have thought, imagine if we could create an experiment between here and the moon.

where somehow we could send a signal and see if we could get a different signal before the light from the earth would get to the moon.

That's a really cool idea.

Some people think that we could get that experiment off the ground in half a century or so.

I am less optimistic, but it's a possibility.

Interesting.

Wow.

It would have to be through quantum entanglement.

Well, that's one way to do it.

You have to get rid of what we call local hidden variables in order to be able to do that.

But that's, again, a deep conversation for another time.

That's a lot of Bell's theorem stuff to unpack in quantum.

First of all...
