My understanding is that an outside observer sees objects undergo time dilation as they approach sources of gravity, such that at the event horizon of a black hole, a distant observer would see time stop for the infalling object, with it seemingly suspended at the event horizon forever.
If that is correct, then it seems to me that some event horizons should appear to be clusters of stars which have fallen in over the eons, or more likely, bright areas, with the brightness of millions of stars which have fallen in over billions of years.
Are event horizons bright? If not, why not?
