"instead of what we actually see, which is that matter and light get completely sucked in"
We actually never see that
"Due to this effect, known as gravitational time dilation, an object falling into a black hole appears to slow down as it approaches the event horizon, taking an infinite time to reach it. At the same time, all processes on this object slow down, for a fixed outside observer, causing emitted light to appear redder and dimmer, an effect known as gravitational redshift. Eventually, at a point just before it reaches the event horizon, the falling object becomes so dim that it can no longer be seen."

- skj 12y agoThis is completely consistent with my statement :) Our time perception of the object remains the same, but the processes experienced by the object itself are much slower, relative to how we perceive them. Specifically, if the object falling in is emitting blue light, and let's say that the frequency of blue light is one per second for the sake of doing some arithmetic, then that object keeps emitting 1/second and looks blue to itself. But in our frame of reference, those 1/second actually become .1/second (its time is moving slower then our time), and appears red.
