I think yes, you will. Oh no! I have jsut realised that you will be in the same gravity force as the black hole itself, so you will both my parallel, and, thus, for you, the black hole won0't grow younge,r and neither ewoudl you grow younger for the black hole (if in any case the black hole had eyes).

I wonder the exact same thing. I don't know the answer. someone help us, please.

I think that maybe you will always fall down, because for example, imagen a black hole grows and a star nearby enters the bh's horizon. Then, imagne the star is being pulled on the opposite way fro the bh, by a gravitational atraction, around a much bigger star. Then, the star would end up faling down to the bh. this is because the gravity produced by the bh is much bigger than the one produced by the big star, or than enything else in the unvierse (apart form other bigger bh). So I think you can get out of a bh's non-return horizon by having another bigger force than the one that the bh's gravity has on you. This force would need to me gigantic.

I'm not sure about this one either. As I said in the other post, I think that you would see the universe getting smalle,r going back in time, matter and energy becoming 1, galaxies compacting.....i.e. you would see the birth of the unverse. But this is very very very very contradictory, abstract and paradoxical. So I think this idea to be wrong. But I don't ahve a solution to it.
