Yeah, that might surprise people. The bigger it is, the less noticeable it is that you've crossed the event horizon. One way to think about it is curvature is less noticeable the bigger it is. So if I'm standing on a basketball, I'm very aware I'm balancing on a curved surface. My two feet are in different locations and I really notice.
But on the Earth, you actually have to be kind of clever to deduce that the Earth is curved. The bigger the planet, the less you're going to notice the curvature, the global curvature. And it's the same thing with a black hole, a huge, huge black hole. It just kind of feels like just flat. You don't really notice.

Yeah. At first, at least, you might not realize what's happened. There are some hints. For instance, black holes are dark from the outside, but they're not necessarily dark on the inside. So this is a kind of fascinating that your experience could be that it's quite bright inside the black hole because all the light from the galaxy is can be shining in behind you.

And it's focusing down because you're all approaching this really focused region in the interior. And so you actually see a bright white flash of light as you approach the singularity. I joke that it's like a near-death experience. We see the light at the end of the tunnel. So you would see millennia pass on Earth. You could see the evolution of

the entire galaxy, you know, one big bright flash of light. So it's like a near-death experience, but it's definitely a total death experience.
