And why do you think that?

That is the starting point.

When we come upon this possibility of other universes...

It's not a crazy idea that we dream up late at night when there's nothing else to think about.

These are ideas that emerge from the fundamental equations that we use to describe the things that we do see in the world around us and we follow the equations and the equations suggest to us there might be these other universes.

So we have equations, we analyze them, and we interpret what they're telling us about reality.

But those are the very equations that come to this possibility of other universes.

Then those are the equations that govern those other universes.

The starting point is let's assume that these are the fundamental... Doesn't it sound an awful lot like, why is God three in one?

I couldn't disagree with you more.

I thought not.

It has absolutely nothing to do with faith.

The reason why we trust the equations is because we've got centuries worth of observational and experimental evidence that the equations take us in the right direction.

Here.

Here.

and it's those very same equations that work here that we are following to their logical conclusion to see where the mathematics takes us right so if you remember the the train of reasoning here you might have just projected here into there that's faith talking though you can't go there all you can do is say well what works but my deep understanding of here

I don't know why it has to be, but that's what you just said.

No, it's actually the reasoning goes in somewhat reverse order from that.

We build mathematical equations to describe here.

We then follow those equations and say, oh my goodness, those equations that we developed to describe here are telling us that there is something over there.
