I"m not too sure about other dimensions, but I always wondering what Black Holes suck everything in to?

Well its just a theory, I just think its something like a different dimension. Maybe, its a time warp! Or it makes you travel 1000 light years away :O! But I still think it doesn't kill you unless of course it warps you into, like in the middle of ocean or something XP. Then you would drown xD

Black holes are fascinating, we really know so little about them. I think it's amazing how they suck in everything, even light and information, so you can't see the actual black hole, whick is the reason for them being called "black". We can only see them because of the big cloud of gas and rocks and stuff that they're pulling in, if I remember correctly.

now i want to be in a black hole!

Yeah I think it's amazing how they suck in LIGHT, I mean how can you suck in light?! It's...LIGHT! You can't do that! xD But somehow its possible! =O. I wish I knew where everything that is sucked in goes to, though.

now i want to be in a black hole!

Hehe, not sure I'd wanna be in one, it'd be scary probably x3

true....xD

Sparky-Drai is bang on 8D omg I love it when people know stuff about this it makes me feel less of a loser. <3 xD

They're really weird things. In the equations it's basically you end up dividing by zero and the result is a black hole. It's basically you have SO MUCH STUFF and it's so heavy. The gravity of it squishes things together, heating them up, usually Hydrogen in a star, and when that gets too hot you get fusion which releases a lot of energy, pushing against the gravity of things. So stars exist in this delicate balance. But when all the Hydrogen has been turned to Helium, there's no pressure pushing out any more, and the whole thing collapses. This happens to all stars, but if the star is particularly heavy, like 3 times the mass of the Sun, it's so heavy that the parts that make up atoms, which usually stay a certain distance apart by strict rules of quantum mechanics that tells them where to be, there's so much force that these particles can't even obey those laws and get squashed down to a point, a "singularity".

That's what the equations say, that the mass part of a black hole itself has no width. It is a point. But there might be some laws of physics we don't know yet that says it's not zero. But that's not all about a black hole. Like you say, it sucks in light. It's because the black hole has such strong gravity that it bends space time in a crazy way. Light likes to follow straight lines in space-time and close to a black hole this means it all falls in because it's all bent up. This boundary is called the event horizon. If you cross it, you don't feel anything, things don't start looking all weird. But if you had a friend with you standing well away, and every second you flashed a laser at them like a clock, they'd see tick tick tick, tick, tick... tick... ... tick... ... tick... .... ... until finally it LOOKS like you're frozen in time when you cross the horizon. For you nothing's happened and you're still quite happily going la la la, but you can never EVER escape now, there's no way to send a message to your friend, that's it. You're going into the black hole =o

There are wormhole theories, the equations spit out black and white holes because of a square root sign, but white holes don't obey certain laws and we don't see them so maybe not. If there was a worm hole and you were spat back out, it would have to be another black hole like object with it's own event horizon. So you wouldn't be able to escape that black hole's event horizon, but you'd be able to see out, because all the light's getting sucked in. Do you can go OOO PRETTY but you can't go explore =(.

The most likely event however is that you get sucked into the middle part of the black hole. and by sucked in, it really means destroyed most comprehensively. As you get closer, the difference in gravity between your feet and your head, stronger on your feet than your head, will tear you apart, and those pieces into smaller pieces, until you're atoms, then particles, then NOMNOMNOM. Everything about you is destroyed. As far as the universe is concerned you don't exist past the event horizon, you've just added your mass to the black hole and made it bigger. But it matters to you(!). xD

Although technically we don't know what goes on behind the event horizon as we can't gather evidence because light can't escape, but these are what our current theories suggest. =]

Here's a pretty picture which shows light being bent. Doesn't have to be around a black hole, mind, just something that can bend space-time a lot. The light from the thing behind gets bend around the thing in front, and we see these Einstein rings. =)



I have an exam in this tomorrow, that's my excuse for the verbal diarrhea. << >> << I wish there were spoiler buttons so I could not stretch the page so often. xD

So you get eaten by the black hole at the end? XDD.
Does it hurt LOL? Or do you just kind of...not feel it? I guess it's hard to explain. Do you like really get RIPPED apart is it just kind of...kid-friendly I guess you could say xD.

[kind of off topic but not really]If we were ever to discover time travel and transportation, which do you think would be easier to figure out?

[seriously off topic, sorry T_T]Do you guys like my new icon? I made it myself xD Sorry for bragging but I'm so proud of it xP

Every time I think of that the universe is neverending... It's just so WEIRD!

They actually suck in all of the light energy, which is what I find the most interesting.

Scientists believe the Black Holes make up 90% of our Universe. Isn't that amazing?

And the reason that we know that they're there, is because we can detect the waves that they send off. (I forget which waves xD).

I learned that Titan is suitable for life.
