Black Holes, for Eta Carinae

This is very well stated. I've wondered the same thing.I wonder if it's that the matter approaches the black hole, but never enters it from our perspective, so even though at the end of time the matter might end up at the center of the black hole, at present all the matter of all black holes in the universe actually exists at their event horizons. Gravitationally we wouldn't be able to tell the difference.--Percy

When only distance is a factor then I think you mean time latency, and this need not be considered. But if you're actually thinking of the Hubble effect where increasing distance usually means increasing speed of separation, then there is certainly a time dilation effect that must be included.--Percy

I think I understand what you're trying to say, but the way you've expressed it makes it seem like you're assuming that light has a different velocity in a gravitational field. I think you probably intended to say that given an observer stationary relative to the black hole that both gravity and relative velocity contribute to time dilation. If so then we agree, but wouldn't the velocity of matter at the event horizon relative to the black hole be zero?--Percy
