And we've got a great network of scientists.

So, I explain this in chapters, I think, 17 and 18 of Return of the God Hypothesis, the experiments that give you this idea that matter can – it's the double-slit experiment that it can be – that small bits of matter may act as waves and particles at the same time.

Mm-hmm.

This becomes relevant in the cosmological context for a really interesting reason that relates to what I was just saying.

One of these infinite universe cosmological models, maybe the most popular one, is called quantum cosmology.

And the idea is that when you go way back in time, the universe would be small enough that in addition to whatever's going on with Einsteinian gravity—

there would be quantum effects would start to take over.

And so when the universe is super, super, super small, whatever that is is going to act in a quantum way.

It's going to be spatially extended and spatially discrete at the same time.

And if it's spatially extended and spatially discrete, can you really say that it's the kind of thing that would cause curvature like most matter does in space?

Larger chunks of matter do in Einsteinian gravitational physics.

And so there's this worry, well, maybe we can't back extrapolate all the way to the beginning because we just don't know what things would have been doing in that kind of a regime when things are that tiny.

But here's the interesting thing.

Our best attempt to depict that is we've applied one of the equations from quantum physics called the Schrodinger equation and adapted it to that cosmological context.

And that adapted equation is called the Wheeler-DeWitt equation.

And when the physicists try to solve that equation, they get a picture of –

all the different types of universes that could emerge, the different universes with different gravitational fields and distributions of matter, different spatial configurations and distribution of matter.

And so they depict that, the solution, they've got a big hairy equation.

If you solve it, then you get what's called a psi function, a wave function that describes an ensemble of possible universes that exist in superposition.

So different universes, they're different from each other, but they exist simultaneously.
