Natural Science 301 Guidelines
This is an open forum area for all members for discussions on all issues of science and origins. This area will and does get volatile at times, but we ask that it be kept to a dull roar, and moderators will intervene to keep the peace if necessary. This means obvious trolling and flaming that becomes a problem will be dealt with, and you might find yourself in the doghouse.
As usual, Tweb rules apply. If you haven't read them now would be a good time.

So it basically means that if you were approaching the black hole, you would not experience the passage of time, but time is still elapsing. Zip off fast enough from Earth and then come back two hours later, a few centuries might have passed for the Earth itself.

If time slows down as you approach the singularity and basically stops at the event horizon (the speed of light), then it would basically take an eternity for anything to actually fall into black hole wouldn't it?
But I'm seeing discussions that cover both possibilities - that you fall in as you observe it, even though people outside see you stop at the surface (so to speak). Others say you never actually fall in.
My guess is nobody actually knows for sure if a collapsing star ends with multiple solar masses on an event horizon surface infinitely squashed or inside the event horizon itself in some infinite or nearly infinitely squashed form.
JimMy brethren, do not hold your faith in our glorious Lord Jesus Christ with an attitude of personal favoritism. James 2:1
If anyone thinks himself to be religious, and yet does not bridle his tongue but deceives his own heart, this man’s religion is worthless James 1:26
This you know, my beloved brethren. But everyone must be quick to hear, slow to speak and slow to anger; James 1:19

Originally posted by oxmixmudd View Posttime for you slows down, but not time as it relates to the observer watching you fall. So your motion doesn't stop in this universe because time stops for you relative to this universe. E.g. supposing you are orbiting at the speed of light. You are still moving, but time is stopped for you.

Originally posted by Sparko View PostWell if time slows and/or stops for you as you fall in, that means you would "take forever" to fall in even from someone observing you from the outside. They would see you moving slower and slower, as the gravity sucks you closer and closer to the event horizon. I think they would see you stop at the event horizon. So nothing actually goes into the event horizon and into the black hole. It all stops at the event horizon."Any sufficiently advanced stupidity is indistinguishable from trolling."

Originally posted by Sparko View PostOr if we do, then does time actually slow down and stop at the event horizon?
In any case, nothing with mass can actually move at the speed of light, so time can't come to a stop for anything other than photons."Any sufficiently advanced stupidity is indistinguishable from trolling."

Originally posted by TheLurch View PostDon't think so. The event horizon's a fair distance from the singularity (to the extent that distance has meaning in this context), and i don't think it's the event horizons meeting that we're detecting.
Whose time? The whole discussion is couched in terms of "time as experience by" issues.
In any case, nothing with mass can actually move at the speed of light, so time can't come to a stop for anything other than photons.
And while time would pass differently for two observers, one near the event horizon and one farther out, each observer would see the time change in the other observer. The one near the event horizon would see the outside universe and the other observer speed up, faster and faster as they neared the event horizon, to the point that the entire universe would pass by into heat death in a flash before they entered the event horizon itself. The observer watching the one falling into the black hole would see them slow down, slower and slower till they stopped moving frozen in time as they fell in.
