    1 Does a black hole pull only 3 dimensional objects? Let me say, does it pull in time?

    2 Black holes emit low frequency sounds, yet pull in everything else. Why?

    basically,
    according to the most recent schools of thought there are the the 3+1 dimensions(that we know of;) ) the fourth being time. a black hole meerly
    twists the fabric of space and time. the closer you approach the black hole,
    the slower time passes from the perspective of the person who is going in. conversely, to the outside observer time is passing at "normal" speeds. so to answer your question space and time are twisted. but then again who really knows.

    I wasn't aware that black holes were anything more than scientific speculation. I don't think that black holes could pull in time, since "time" does not even exist per se, but I do think that enough gravity could warp time (make 5 minutes into hours or vice verse). It would be hard to test such a theory though, since if you got close enough to a black hole you would probably be compressed small enough to fit into a sardine can.

    Thank you for the information.

    sky_pink er... what's the time?

    I hope not. Every post contained at least something utterly ridiculous.

    I'll attempt to say something about at least a few of the things.

    * There are AT LEAST 4 dimensions, possibly more than 10 (they don't matter though, being "rolled up").

    * Time always passes normally for a person. Someone might see a person going in a black hole, he would see this happen slowly, but not because his sense of time would be different in any way; the light would simply be affected by the gravitation. Time always seems to flow normally for any person, that's the only way that time can actually exist.

    * A black hole doesn't swallow time, it warps it.

    * I don't see why anyone wouldn't be able to reach the singularity once in a black hole. Er... to be honest, I don't how one could AVOID it once inside...

    * A black hole doesn't emit anything, but there's a complex process called the Hawking radiation that makes it possible for a black hole to become smaller.

    * An area free of gravitational forces? I'd like to see it in this universe!!!!! :rolleyes:

    Yeah! I heard about time warping. Like to an outside observer your going at normal speed and if you could reach the center of the hole it would look to everyone like you were falling forever right?

    Why are y'all pretending to know anything about this? No offense, please, I don't mean this in any shitty way, but we can even begin to understand any of it. I think physics explains alot of it, but cannot even begin to explain it all since we've barely even begun to get into it. I suppose most of the pholks on this thread have at least heard of dark matter, (supposedly makes up the majority of the universe) and I think that'll play a big part in all the shit that's confusing us.

    i've no doubt that black holes exist. I've no doubt that there is alot of shit out there that exists. Until we know more about...everything we dont know about....it's almost useless to discuss it. :) I'm not discouraging ya, it's a very interesting subject.

    Ok, I'm no specialist... anyway, I've read this about spacetime tearing, never seemed more believable than spacetime warping, I must say. However, I've never read about this idea of singuarity actually "falling". May I ask where I could read up on that? Sounds really strange.

    A black hole does NOT emit material. The whole definition of a black hole is that it doesn't emit material. However, it does some weird things to the material that hasn't been pulled into the hole yet. Two high-speed jets are ejected in opposite directions from the inner part of the accretion disk, which is heated by the gravitational energy.

    I highly doubt your physics professor ever tried to tell you there was matter coming out of the black hole. He probably did mean the jets of the accretion disk.
