When we speak of zero point energy of the vacuum of space, I think that's what they're referring to.

The energy below which you cannot go, because it's zero point, but it's not really zero, but

If you try to get to zero, that's what you're stuck with.

And that's quantum fluctuations.

And I don't think you can extract energy out of that lowest energy fluctuation because it needs, to take energy out, you need a lower energy state to land in.

And you can't.

Who's that guest we had in another show, a biologist, who said, the universe is just electrons looking for a place to rest.

That's it.

Yeah, that was Betul.

Betul, yeah, Betul from University of Madison, Wisconsin.

Betul.

The universe, everything that happens in the universe is an electron.

Looking for a place to rest.

Looking to hang its hat.

A hard day in the circus.

So, yeah, but people imagine that you could tap the zero point energy and make like rockets out of it and travel through space.

And I don't have problems people imagining that.

It doesn't seem likely to me, though, based on what we know of the behavior of quantum physics.

Gotcha.

So there you have it.
