There's no way to tell what's going on inside a black hole except what the theoretical models tell us about it. That's because nothing can get out. So information about the interior can't be carried out on a beam of light, say, because light itself can't get out. The gravity is way too strong to allow anything to get out (there is a major exception to that but, unfortunately, it can't tell us anything about what's going on inside).

Even the laws of physics might be totally different and bizarre inside a black hole but there is no way we'll [ever] be able to directly observe it. I'm hedging my bets a little bit by putting 'ever' in brackets because I think it's kind of presumptuous to put limits on what our descendants will be able to do or not do thousands or millions or billions of years from now, if they're still around.

Well now I am really curious.

I bet those who study the science of astronomy are super curious to know what is on the other side/ in side these black holes.

Another dimension? Other galaxies? Time travel? An exciting thing to try and find out.
