Well what about this: Since relativity of simultaneity ultimately leads to proof that no object can travel faster than light, you can't assume beforehand that no object can travel faster than light. So shoot something that travels instantaneously to signal that lightning struck the point

Chapter 9 on the theory of relativity discusses a thought experiment (http://www.bartleby.com/173/9.html) about a passenger on a train that claims that it is impossible to say in an absolute sense whether two events occur at the same time if those events are separated in space. I have...

I could see if the ship were orbiting the black hole. But what if it were traveling towards it like a 1-dimensional line. The force pulling you in is finite, if you push back with a slightly greater force you should still get sucked in?

I read that there is no way to escape a black hole once you enter the no-escape-boundary, no matter what you do. Your ship travels directly towards the center point of the black hole so that it doesn't orbit it. After it passes the no-escape-boundary, you thrust in the opposite direction with a...
