It is possible to survive travel through a black hole, if it large enough. It may be possible for the entire earth to get sucked into a large black hole intact. There are a lot of small black oles wandering the galaxies, but the big ones are pretty much stationary in the middle of galaxies like ours. There is in fact a huge black hole at the middle of the milkyway. Since you can not see a black hole they had to observe the orbits of stars at the center of the galaxy. The stars wold ahve erratic orbits and travel at amazing speeds close to the black hole as it got slingshotted around.

A friend told me that if you got too close to a black hole, you wouldn't ever actually be sucked in, just really really really stretched out. Any truth to that?

I may have not watched that program trav, but this forum has taught me that your mind is a black hole.

Evil Homer: Small enough mass black hole only. It's called spaghetification and it's a result of tidal force.

I don't know how anything can survive through a black hole though. I would think if something is inside the event horizon it'll just keep falling towards the singularity and disintegrate as it reaches it.

Pick up "A Brief History of Time" by Stephen Hawking, Trav. Everything you wanted to know about black holes is in there, and it doesn't take a theoretical physicist to understand it.

Cool, I will go check that out man.

Did you mean to say a worm-hole, rather than a black hole?

Well, at least I'm not the goatse guy. That has to count for something.

Thanks for ending yet another thread with pointless and pathetic attempts to be clever.

Who said I was trying to be clever?

no, I meant black holesI don't get that, given that a black hole is no hole at all, but rather is a remarkably dense body. How is one supposed to "travel through" it?

That's a good question.

I recently took astronomy in college, and learned all about black holes.

Black holes aren't a "hole"... but merely a super dense neutron star that has so much gravity that it won't allow light to escape up to a certain point. You can identify black holes by watching gases and dust nearby and watch it get sucked into nothing.

And if you watched a person go into a blackhole, supposedly you would see the person enter, and they would appear to be frozen in time image-wise, and meanwhile their body would be getting sucked towards the center of the black hole, which has the neutron star.

Normally the only neutron stars that are powerful enough to create black holes are from supernova explosions from stars that are about 20 times the size of our sun.

There are different sizes of black holes from super massive to small. I guess if you got sucked into one you would just be compacted in with the rest of the matter? I thought there was another side of the black hole that spewed matter out into space or something like that.
