If you had an object moving away from you at near C and it was emitting light that was pulsed at 1 Hz (from the point of view of the object) and you were to view it from a stationary position (earth), what would you see? It would be red shifted and the pulse rate would be slowed down? Would the...
Well your saying that light coming towards a black hole is blue shifted. If this is the case then some of it would escape and appear at the edge of a black hole in an actual observation?
I am rusty but if you let v exceed c:
1/((1-(v^2/c^2))^(1/2))
The result is imaginary.
Looking at the black hole from outside the event horizon everything at the event horizon and closer to the center of the black hole would appear black, wouldn't it? Is this the same as an infinite red shift?
