Is it just a big vacuum, or what?

A black hole is the remenent of a star. If the star weights of 10 space tons (or something like that) it will collpase on its self and create a black. Black holes have such strong gravitational force that they suck in even light, and bend the fabric of space and time, so that time around a black hole is altered. They basically suck anything cought in it's path... so i hope that answers your question smile blaugh

Black holes are the ultimate nightmare for the average physics student. Gravity is normally created from mass, but black holes are stars that were crushed under their own mass, thus making them shrink to an infinitely smaller point. The gravity is still there, but no discernible mass. I tried studying some of Einstein's theories, but that only made it more mind boggling.

Astronomy magazine, November 2007 issue, has a fascinating article titled "The secret lives of black holes" by Steve Nadis.

Soo where does all the objects that get sucked in go?
Does it just compress to something the size of an atom cause the gravity is soo strong? o.o

Damn right! razz

I would say that the mass is still there, except that it is extremely compressed. Also any objects that get "sucked in" are also compressed and added to that mass.

So black holes are the remains of the very big stars ("very big" = bigger than 1.5 sun-mass) so, when they collapsed, they can creating SO big gravitation, that everything, that step across the event-horizon, will be pulled. The concepts, that we know: mass, time, space losting their meaning, that's singularity. Am I right? sweatdrop
And sorry for the mistakes, I'm Hungarian... sweatdrop

Try to read Einstein's own writing, it's not too hard, I think. wink
