The question is "If time dilation at the event horizon becomes infinite (for an outside observer), how can anything ever pass the event horizon (as seen from the outside), and wouldn't that mean that we (as outside observers) never see a black hole form in the first place?"In fact, infalling matter to a black hole *will* appear to stop at the event horizon. (Also: If there is a singularity in the center of a black, would the space inside the event horizon be infinitely large? The funel shaped singularity in 2D space looks like it goes down infinitely far, thus having infinite volume.) However, this would have the implication that no black hole has formed a singularity (region of infinite density) at its center yet, and never will. That would seem like a workable explanation for me, who never did any actual calculations about any of it. So couldn't we explain the apparent paradox by saying that what we call "falling into" is really "pilling up at the surface"? (And if I am not mistaken, it's the diameter that grows proportionally to the mass of the black hole, not the volume, so it grows rapidly in diameter any time mass is added.) And larger black holes also have less density. Since any particles that are still an infinitesimal distance away from the event horizon would appear to move at infinitisimal speed as seen by an outside observer, couldn't we say that all particles basically pile up infinitely close to the event horizon in an infinitely thin layer?Īny mass that "falls into" a black hole causes the event horizon to grow in diameter. Now here's an idea how to possibly make sense of this: When mass aproaches infinitely close to the event horizon, the time dilation also aproaches infinity. But we on Earth see "the effects of invisible sources of massive gravity that can only be explained as being black holes", and given that the universe is not infinitely old, these must have come into existance in a finite amount of time. Usually the parts in the bracets are not spelled out and so all the answers almost always come down that to anyone falling in time keeps on going normally. The question is "If time dilation at the event horizon becomes infinite (for an outside observer), how can anything ever pass the event horizon (as seen from the outside), and wouldn't that mean that we (as outside observers) never see a black hole form in the first place?" A very popular question that you can find asked all throughout the internet, but as far as I can tell never gets answered.
