If there were 2 observers, 1 at rest with CMB, and the other falling into a black hole, how much time passes for the observer at rest with CMB while the other falls past the event horizon?
I ask because I keep reading that time dilation (due to gravity) will cause the object falling into appear to never fall past the event horizon from the perspective of the outside observer.
I don't understand how anything has had time to fall past any event horizon because an infinite amount of time would pass for an observer at a distance, and an infinite amount of time has not passed in the universe
But things have clearly fallen into black holes in a universe with a finite history and observers (or objects) at rest and not falling in.
What am I missing?
