Falling into a black hole

A black hole is defined to be a region of space-time where escape to the outside universe is impossible. The outer boundary of this region is called the event horizon. Nothing can move from inside the event horizon to the outside, even briefly, due to the extreme gravitational field existing within the region.

No, objects falling into black holes actually do cross the event horizon due to the overwhelming gravitational forces. The mass of the black hole, therefore, is increased as more matter is pulled in.

I believe what Richard may be speaking about, is something I thought I heard on a science show RE; BLACKHOLES.

If I remember (understand correctly) - either an observer outside the influence of the blackhole - OR - the ufortunate lug falling into the hole - would never see the other DISAPPEAR, due to the effects on light waves causing the scene to remain forever for rhem.

I know this sounds kinda stupid since the one falling is said to be "spegettified" from the gravity forces, thereby dead - eventually, but, just wanted to C m A in all respects :cry:

if anyone has info about this, as to my accuracy, let me know

thanks,

I agree with what people have to say about the black hole, but I feel that its not the end of the universe.
There is more into it that we can think of.

Hello! can we travel in time by jumping in to the black hole?

still we dont know much about the black holes
I suppose that we shall not even exisit if we come even close to a black hole , we shall disintegrate to small particles , so practicaly we would never know really how it would be if we fall in a black hole

lack holes simply move too slow to reach the matter nearer to the edge of the universe. Therefore, in the extremely distant future(barring any extra-universal events), the edge of the universe will likely be the safest place to live--if we can just get there! ;)
