So very plainly, I would kind of describe the wormhole like a subway tube. So you get in on one side. So let's say you're getting in on Penn Station in New York and you get off at Grand Central. But the in-between, right? So just like the subway is going underground, the wormhole is kind of like what we call like a hyperspace. So you're not actually...
You know, traveling, like if you were on the surface, you're kind of tunneling through space-time itself and then coming out on another side. So it's a very weird kind of like physical attribute.

I think the rubber sheet analogy is a scam. I think it's because it doesn't actually. So again, like our definition of general relativity, it doesn't give you the accurate description. This is an introductory to curved surfaces and things like that. Yeah. But it doesn't actually show you the dimensionality of space and time.

So instead of using the rubber sheet, I tended to use putty. You can ball it up into whatever shape you want. and then deform it and curve it and spin it around. And now you're getting all of the physics that's kind of involved in the different configurations of space and time, which is general relativity.

This is why, again, I say that the rubber sheet analogy is a scam because we assume that black holes are actually holes in space. They're not. They're spheres. And so they're actually squished spheres because they're rotating, right?

So it's a great image. And we've seen these. We've taken pictures of black holes and galaxies and seen that these are circles. These are spherical objects.
