Indeed. To be clear, I was trying to ask about the speed at which you'd have to travel in order to approach (but not enter) an event horizon. Say, a distance of one meter. Or one millimeter. Does your speed have to exponentially increase the closer you get?
- bashinator 12y agoThis isn't a direct answer to your question, but it might help. At 1.5x the radius of the event horizon, only photons can maintain a stable orbit around a black hole. If you get closer to a black hole than that, the only two options are to be ejected entirely (hyperbolic "orbit"), or to be captured and enter the event horizon. For objects with mass, this distance increases.
