These are big questions. These are big questions in pretty much every field. For the universe, we do consider it, it's everything there is by definition. But people now think about it as one of many universes. And of course, it's a misnomer. But could there be other places where there are self-contained gravitational systems that we don't even interact with?

But those are really important questions. And the only way we're going to answer them is we go back as far as we can. We try to think theoretically, and we try to think about observational consequences. That's all we can do.

So I like to think of the universe as being out there whether or not. I mean, it would be really weird if the only time things came into existence was when I saw them or I measured them. There's a lot of weird stuff. I mean, I could believe that the Middle East doesn't exist because I'm not there now. I mean, that would be kind of ridiculous. I think we would all agree on that.

So I think there's only so much that we can attribute to our own powers of seeing. So, and the whole system doesn't come into being because I'm measuring it. And so what is weird, and this isn't even a disagreement about the standard model, this is a disagreement about how you interpret quantum mechanics. I mean, I would say that those wave functions are real.

I mean, one of the things that, don't forget that particle physics does that quantum field theory says is that electrons can be created and destroyed. It's not that every electron has to be in the universe. I mean, there can be, I mean, that's what happens at colliders, particles get created and destroyed. But that doesn't mean that if I have an electron in an atom, it's not there.
