Question: is there a different dimension on the other side of a black hole like a white hole?

That’s a super good question! Many people think there could be and that perhaps that’s how our Universe came to be. The problem is that we can’t really go there to see without, well… dying! But we can try to work it out with physics, maths and super-computers and we certainly will be able to answer that question hopefully sooner rather than later!
