OK. And like we said earlier, right, like the tunneling of a wormhole is this like connection from a black hole that consumes matter to this like theoretical white hole that pukes out matter somewhere else in space.
This image is like hard to reconcile with like the classic way teachers describe space time, like this 4D stretchy sheet. Like think of this trampoline material with like a bowling ball in the center. And that's like a star in space time. Like how do you feel about this like stretchy sheet metaphor?

Yeah. And maybe like another complication, like for people who have heard it, is this idea that black holes are like potholes in the fabric of space-time. And we've said it before on the show, because it's a great way for scientists to convey this like huge amount of gravity, right? But in a conversation about wormholes, maybe it's too simplistic.

It's better to think about a black hole as a sphere.

Okay, I love that image. It's like a dumbbell. But why are people so resistant to wormholes' existence? Why would we not see one in nature?

So like not regular matter that like clumps to itself.
