An example of something that emerges is consciousness, right?

So we say, well, consciousness, it emerges from all these atoms in a particular pattern that's your head or your brain.

And in the same way, people are beginning to speculate that space and time emerge from something, some kind of building blocks.

And we don't really know what they, well, we don't know what they are.

But until we know that, it's difficult to talk about a beginning.

Because you're right, Jason, that when you say time, then you're right, that container is a good picture, isn't it?

If you have a beginning and an end, that contains everything or brackets it.

But we don't know that.

Do you know, so Einstein's picture, so relativity back from 1905 and 1915,

There's this idea called the block universe, which means that every moment is still there.

It's like a map.

So you could imagine drawing a map of the world now.

So I could leave London and come and fly to Los Angeles.

You wouldn't say that London has gone.

You'd say somewhere.

So in this case, in Einstein's picture, all those moments, all your memories, all your past and your future exist somewhere in space-time.

And you just travel over the map.

That's an idea called the block universe.

So the way to think about it, what's happening is, so light travels one foot.

per nanosecond.
