#468 – Janna Levin: Black Holes, Wormholes, Aliens, Paradoxes & Extra Dimensions

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.

It's called a Casimir energy, and that can have a negative energy. It can actually... cause the place to attract or repel depending on how they're configured. And so you could kind of imagine doing something like that, like having wormholes propped up by these kinds of quantum energies. And people have thought of imaginative configurations to try to keep them propped up.

Are we at the point of me saying, oh, this is an engineering problem? I'm not saying that quite yet. But it's certainly plausible.

That's going to be really challenging. So I'm not saying it's simply an engineering problem, but it's all within the realm of plausible physics, I think.

People have looked at that. They tend to be non-traversable wormholes. They're not trying to prop them open. But yeah, I mean, some of this ER equals EPR quantum entanglement, they're trying to connect black holes. Yeah. You know, it's really cool. Again, it's not quite following the chalk. And by that, I mean, we can't exactly start at a concrete place, calculate all the way to the end yet.
