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

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.

The problem is, is by all our methods and all the understanding we have, that energy's either really, really huge, huge energy, way bigger than what we see today, or it's like zero. So that's a numbers problem. We can't naturally fine-tune the energy of empty space to give us this really weird value so that we just happen to be seeing it today.

But again, we can think of a kind of dark energy that exists. So the question is just why is it such a weird value? not how is this conceivable, because we can't conceive of it.

Yes, there's absolutely a phenomenon. Nobody's going to say they're happy with that. We're all going to say there's something we don't understand, which is why we look to the extra dimensions. Because then you can say, oh, maybe it has to do with the size of the extra dimensions or the way that they're wrapped up.

And so maybe it's foisted on us because of the topology, the connectedness of the higher dimensional space. These are all things that we're exploring. Nobody's landed one that's so compelling that your friends like it as much as you do.

I think dark matter might be less peculiar than dark energy. My hope is that they're all tied together. That would be very gratifying. These aren't just separate problems coming from different sectors, but that they're actually connected. That the reason the dark matter is where it is

in terms of how much it's contributing to the universe, is connected with why the dark energy is showing up right now. I would love that. That would be a solution like no other, right? And like I said, if it revealed something about dark dimensions, you know, that would be a happy day.

Yeah. Dark matter is localized in space. So it clumps. I mean, it doesn't clump a lot, you know, but I mean, it's around the galaxy, right? It's in a halo around the galaxy.
