Brian Greene

I'll tell you that I love you.

And I love you.

Best to you.

Best to you out there in the podcast universe.

Until next time, we will say, we do say, and we must say.

Brian Greene, professor of physics and mathematics, Columbia University.

Now, you can't take that too far.

None of us really imagined that if you asked the equations, what are we gonna have for dinner tomorrow night, the equations will spit out fried tofu and spring rolls or something like that.

But at the level of the fundamental ingredients, the particles that make up the universe,

their properties.

The hope and the goal is that the theories that we work out will apply everywhere and tell us about everything.

You just said everything.

Yes.

As in everything.

Right, so there actually are a number of ways that physics comes upon this idea of other universes.

Maybe the most intuitive

is to think about the Big Bang that sent space rushing outward and matter could cool and yield to stars and galaxies, that wonderful picture that we've had with us since the 1920s.

We have, in the interim decades, come to the possibility that the Big Bang may not be a one-time event.

That is, there may have been many Big Bangs, there may continue to be Big Bang-like events, each spawning its own universe.

If that were the case, then our universe would then be viewed as one of many in this grand collection emerging from all of these events.
