And again, quantum mechanics often does violate those energy conditions.

Yeah, I mean, sometimes I assign in an advanced general relativity class the assignment of inventing a warp drive. And it's kind of similar. So the idea is, here's a place you want to get to. And can you contract the space-time between you with something antithetical to dark energy, the opposite, and skip across and then push it back out again? You can do that in the context of general relativity.

Now, I can't find the energy that has these properties, but I also can't find dark energy. So we've already been confronted with something that we look at the space-time. The space-time is expanding ever faster. We say, what could possibly do that? We don't know what it is, but I can tell you about its pressure. I can tell you certain features about it.

And I just call it dark energy, but I actually have no idea. It's just, that name's just a proxy for what this, it should be called invisible because it's not actually dark. It's in this room. It's not hard to see through. It's not dark. It's literally invisible. So maybe that was a misnomer. But the point being, I still don't fundamentally know what it is. That's not so terrible.

That's the state of the world that we're actually in. So maybe warp drive is just kind of like a version of that. I don't know. I don't know what form of matter can do that yet, but at least I can identify the features that are needed.

Yeah, actually it might. It is positive energy and a negative pressure, which is like a rubber band quality. We think of pressure as pushing things outward and dark energy has a very strange quality that as things move outward, you feel more energy as opposed to less energy. The energy doesn't get lower, it gets more.

It doesn't have the right features for the wormhole, but those are some pretty surprising features. We, again, can conjecture like, oh, hey, you know, the quantum energy of the vacuum kind of behaves that way. That would be a great resolution to the dark energy problem. It's just the energy of empty space, and it's the quantum energy of empty space. That's an excellent answer.
