And if you fall in feet first you see your feet like a flatbed scanner scans an image. When you stand still on Earth, photons from your feet move at light speed into your eyes. When you fall feet first into a black hole, they emit stationary photons on the event horizon, which you cross at the speed of light. It’s all c to you though. (I’m halfway through Cox and Forshaw’s Black Holes: The Key to Understanding the Universe. It’s really good — undergrad relativity written as a pop sci book. I think I’ve understood it so far.)

> When you fall feet first into a black hole [...] which you cross at the speed of light. I don't know where you're getting this but nothing with mass can reach the speed of light. And it's absolutely possible to cross the event horizon (of a very large black hole) without having any idea whatsoever. There would be no particular event to happen that would indicate to you that you did.
