Say we have a black hole. Due to the gravity near a black hole, any object "falling" into the black hole would take an infinite amount of time relative to an outside observer to fall through the event horizon.

So if I'm in my spaceship a safe distance away, and I toss some guy out of the airlock and he falls to the black hole, from my point of view, he would seem to STOP just before he reaches the event horizon. He would accelerate to near the speed of light and time would slow down for him. It would take an infinite period of time for me to see him fall through the event horizon.

Conversely, relative to him, he would fall instantly into the event horizon. He would be looking back at my spaceship and he'd see my spaceship leave the area instantly (after I got bored of watching him just sit there and not move and I left). He would watch planets orbit around the system, stars being born and dying, and spacecrafts flying by... all instantly. He would watch an infinite period of time go by during his fall into the event horizon.

Here's the question. How can that be??? It creates a paradox. If the guy falling into the black hole takes an infinite period of time relative to an outside observer to fall through the event horizon, and the guy falling into the event horizon witnesses an infinite period of time go by outside of the black hole, then how is it possible for him to actually fall into the hole? Won't the hole be gone after an infinite period of time has passed? Won't the universe be gone (assuming it will eventually stop expanding and then have its "Big Crunch") after an infinite period of time has passed? So then how is the victim going to fall into the black hole after an infinite period of time if the black hole (theoretically) shouldn't be there for an infinite period of time?

Have fun...

He'll accelerate to near the speed of light, and to an outside observer, he'll seem to be stuck there - forever. For him, the entire course of the universe will flash before his eyes. He'll see the present, the future, and The End (should The End ever take place).

Problem is, that creates a paradox that I previously mentioned. There's gotta be a way to explain that.

My answer is lame isn't it.

Close? No... at least not to my understanding. To my understanding, the moment an object crosses the threshold known as the "event horizon" (aka the point where once you get in, you don't get out, period), THEN the laws of physics become irrelevant.

As far as I know, the area around a black hole is equivalent to that of a regular celestial body with a huge gravity field.

Come on, chesty! =)
