It's hard to imagine, but the way a black hole works means that you would forever be stuck in it, and it would never lead to anywhere. The distortion of light and time means that you would forever be stuck on the event horizon (from your perspective).

Black holes are mental because they change the perspective of reality depending on your relative position to the event.

If you feel up to it, give the supplied link a read. I would consider myself pretty knowledgable in regards to science, but I found this article pretty tough going to properly comprehend (I'm still not sure that I really understood it even now).

Probably where all my missing left socks are.

Or imminent death.

...so socks or death.

Alice in Wonderland probably! ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I don't think anybody would ever be able to know without going inside one. :)

There is a theory that black holes break down everything in the universe down into basic information and then sends it somewhere else where it would emerge through a "white hole" possibly in another universe, but this is still heavily in mathmatical theory.

I reckon that nobody knows but if we actually focused on space rather than worrying about Global Warming. If we could send camachazie warriors into the black hole then We could get a better understanding of how the black hole works, because if we send them in they may die but thats what they have chisen to do. If we could send them in with camers and measures and stuf like that we could find where it leads to.
