This kind of origami that we're talking about, that you could travel in a straight line through the universe, leave our galaxy behind, watch the Virgo cluster drift behind us and travel in a straight line as possible and find ourselves coming back again to the Virgo cluster and eventually the Milky Way and eventually the Earth, that we could find ourselves on a connected, compact space-time.

But topologically, there's something we know for sure, something beyond Einstein's theory that has to explain that to us. Now, wormholes are a little funky because they're topological. You know, they create these handles and holes in these sneaky, by topological, I mean these connected spaces and structures.

Like Swiss cheese, right. So I could have two flat sheets that are connected by a wormhole, but then wrap around on the largest scale, all this cool stuff. There's nothing wrong with it, as far as I can see. There's nothing... abusive towards the laws about a wormhole, but we can reverse engineer.

We were saying, oh, look, if I know how matter and energy are distributed, I can predict how spacetime is curved. I can reverse engineer. I can say, I want to build a curved spacetime like a wormhole. What matter and energy do I need to do that? It's a simple process. And it's kind of thing Kip Thorne worked on, very imaginative, creative person.

And the problem was that he said, oh, you know, here's the bummer. The matter and energy you need doesn't seem to be like anything we've ever seen before. It has to have like negative energy. That's not great. There are some conjectures that we shouldn't allow things that have that kind of a property, that have negative energies.

Only things that have positive energies are going to be stable and long-lived. But we actually know of quantum examples of negative energy. It's not that crazy. There's something called the Casimir effect. You have two metal plates, and you put them really close together, you can see this kind of quantum fluctuation between the plates.
