But I can tell you, I'm pretty sure all of them have in common the feature that they're saying, here's what I want my wormhole to look like first. So it's like saying, I want to build a building first. So they construct, there's an architecture of the space-time that they're after. And then they reverse the Einstein equations to say, what must matter in energy first?

But it's important because it's how they realized, oh, wow, they have to have these negative energies. They have to violate certain energy conditions that we often assume are true. And then you either say, oh, well, then all bets are off. They'll never exist. Or you look a little harder and you say, well, I can violate that energy condition without it being that big a deal.
