Physics brain-bender
I couldn't sleep last night so I thought of what an object might look like if it could travel faster than light. I came up with a solution, only to come up with a totally different and more sensible solution a few minutes later.
Lets say that there is a ball traveling towards you at 2x the speed of light. At time zero, the ball is one light-second away from your head. At 0.5 seconds, the ball stops by the side of your head (not right in front of your face, or you would only see the ball). What do you see during the whole second?
Big disclaimer: I know that nothing can approach the speed of light, and I know that if it did exceed it, it would be going back in time like the hypothetical tachyon, but just ignore that...
