I'm back for a short stint to clear stuff up. Hi. We seem to have been told that the escape velocity of a black hole at a certain altitude reaches the speed of light. But if the escape velocity is the speed of light, what stops us from being in orbit around a black hole, dipping our periapsis through the event horizon and recording data, then after exiting the event horizon at a higher altitude escape the black hole where the escape velocity is manageable? Or is the orbital velocity at that altitude faster than the speed of light? Has it been an issue of semantics? If things get heavier the faster we go could we plunge towards a black hole, reach the same mass as one near the speed of light, and become a black hole? Or would we sling the black hole away at high speed? What would happen? I'll post more badly formed questions a bit later once I think of some
