black holes, are holes, which suck in everything, and once something gets in the hole,it is stuck their forever. Aren't you curious what it would be like to be in that place?

Some people say that we go to other dimensions, other people say we can go back in time. It is mysterious, because what lies beyond that hole remains unknown

A black hole is just a large amount of mass concentrated into a very small volume.

Escape velocity is defined to be the minimum velocity an object must have in order to escape a gravitational field.

It is said that the escape velocity of a black hole is so great that not even light can escape it.

Which is why black holes are black.
An interesting fact though, is that the edge of the black hole is actually nothing, when you enter inside event horizon you would travel for a while before actually reaching the black hole itself, which is the infintessimally small speck in the middle. For all we know there could be a planet orbiting inside the event horizon of a black hole.
Another strange thought is that the inside of the event horizon wouldn't be black. It would be quite bright, because it would draww the light from surrounding area towards it.
It's doubtfull that anyone could go back in time by using a black hole. They would more likely be ripped to shreds. Unless the black hole is very (very) massive, in which case the event horizon is quite a ways from the center, so gravity isn't greater at one point than another. You would still be crushed though.

Black holes are thin as paper, It is dense at the bottom of the ocean, The pressure is so tense that it just disinigrates.

If you were to throw a ball into the black hole, It would basically just disinigrate.

have you guys ever heard of white holes. Theyre like black holes except they violently eject matter.

Black holes are invisible, but, do to when they suck in a star, just before the star is sucked in, it releases an inferred ray. This is what scientists use to see where Black Holes are located.

A lot of scientists believe a Black Hole is in the middle of our Galaxy, the Milky Way. Andromeda, our closest Galaxy next to us is also believed to have a Black Hole in the middle. This is why we have rotation, is what many believe.

which is wat i was gonna say. it would pull u in so hard u would just rip.

You know how many people have started a topic like this... Lots...

Anyways, black holes are suppose to to be a a hole in space... right? And is a black hole visible from any point of view?



Uh, I thought they were the opposite of black holes or negate them or something like that... And were there any reports of anyone seeing a white hole? That'll be cool.

Hold on... Black holes tear you apart? Or do they crush you to death...

Why dont we launch a video-camera rocket into a black hole and see what happens!?! um... That wouldnt work though right?

Yeayeayea, aprox. 23093290666(BWAHAHAHA)987041 threads have been made about black holes.

Actually it's gamma rays, which have more energy than infrared. If infrared rays were released we could be able to visibly see black holes. They detect the other end of the spectrum.
The reason they are released is because as things get closer to the black hole they spin faster and faster. This increase in speed make many particals bump into each other at high speeds, basically creating nuclear explosions. These release gamma rays which are more powerfull than normal electromagnetic rays, so they can escape the pull slightly easier..
White holes are purely theoretical, they are thought to be the opposite end of a worm hole, where all the stuuf sucked into a black hole exits. But this doesn't make sense because the gravitational pull of the released stuff would come together again.
Gravitational pull gets so differential as you get closer to a black hole. If you fell into one, your feet would feel more gravitational pull than your head, so you would in fact be ripped apart. The peices would be ripped into smaller and smaller peices, at the end they would be crushed into the smallest possible speck imaginable.
If we were to launch a video camera into a black hole, it would be unable to send any message as to what was happening inside, because nothing can escape past event horizon.

It has a gravity that even light cannot escape, and there is not matter in the hole (so it seems), its nothingness, but its there, I'd call it Void. But how can it exist if its nothing, how can it do something if its nothing, there needs to be some sort of mesurable substance there.

If you read the posts in this thread, you'd learn that it ISN'T nothing. Essentially, from what I've read, black holes are essentially a rip in the natural fabric of the Universe, and to some extent, are like holes in a piece of paper, the hole itself isn't really anything. A hole with a very, very high gravitational pull.

It also goes along with the string theory's 4th dimension, and how it is measurable but just not by us because of our size or something like that.

Likewise, the black hole is an object in space, and as an object in physical existence (because it affects the space around it) is must be measurable under some circumstance -- simply not our's.



speaking of event horizon, has anybody seen that movie (titled aptly "Event Horizon" played by the jurassic park dude) freakky movie!

A hole isn't a physical object, is the lack of a physical object in that space. It's measurable how much is mssing and how it effects the world, but it isn't really an object..

Wouldn't you die when you get near a black hole?

SQUISH!

Except that a blackhole is not just a hole in space.
It's only called 'hole' because things seemingly fall into it, as I understand it.


Isn't grass green, brown, or gold?

Some say blackholes are like wormholes; passage ways through time. But that really doesn't make much sense. I see them more like dark stars that take in stuff rather than give off stuff.


Well, if you got sucked into a jet engine, wouldn't you die?

I was being sarcastic, to those people who claim black holes are portals to another dimension. Yeah, it's called "Dead".

Ok, in this other topic (how the hell it got to black holes I do not know) I put something that goes with this. Black Hole
(If you want I can replace this with the actual post I just linked to (better for quoting and such)

it would be kinda fun, then scary, to acually be floating in space, screwin around, then all of a sudden get sucked in by transgravity and getting ripped to a million peices, though if it is possible to live in a black hole, your gonna get hit by asteriods and everything else, possibly a blue giant coming towards you at 10 times the speed of light ripping across your face, and theres always a piece of land where the gravity is coming from isnt there? You would eventually reach speeds up to 10 times the speed of light and have the small speck slam into your chest, that, is painful, though, of course, all matter in a black hole is destroyed befor it even gets into hole realy... but it would be cool going 10 times the speed of light! Playin the real starwars now baby! Well, isnt light made of moleceuls? so if light is gathered enough, and going fast enough, couldnt you feel it or get pulled into the currect? Well, mabye not, but i think space is amazing, it is my favorite subject, thats why this article is so long lol, black holes and white holes amaze me, and its said that they form when a supergiant explodes it creates to much pressure and implodes and created a massive force of gravity ( black hole ) that would be fun to see! Watching out your ship, looking at a massive star, then all of a sudden it explodes and before it even expands a mile off it implodes and creates the loudest rush of sound in history and pulls everything around it together. Has anyone heard about the mission in 2011 about going to neptune? I bet thats gonna be fun going through the astroid belt lol. And all these Huge comets that flyby every 70 years or so, what happends if u land safely on it somehow lol, would you get so far away from the sun that you freeze to death? or would you be going so fast that the wind pressure is so cold that it becomes hot? Woot am i loaded with space facts and questions lol, i better stop here lol!

No. There's not always land. not all sources of gravity are land. Gravity is generated by all matter. Some greater then others. The greater the mass, the greater the gravity. Black hols are generated when the gravity of a star becomes so great that it essentially punctures a hole in space, then everything just stars getting sucked in. From my understanding of it, it's alot like the drain in the bathtub. Except that if something is too large, it's ripped apart by gravity until it fits.

I think it depends on the density of the black hole. If the black hole is smaller, the sides of it is closer to each other and when you travel in, you can be stretched due to the gravitational tug between the sides. but if there is a larger black hole, larger than the sun, there might be a possibility of entering it safely.

I had watched the movie "Event Horizon". pretty creepy i'd say.

We really dont know what the black holes might contain. Maybe it's a passage way into a land of hot babes

Go ahead army, you can go launch off into a black hole.
In my concept a black hole is just something thats really
none of my business. But black holes are collapsed core of an
star. They don't have spaces inside. All matters are in atomic forms
and compressed so tightly you would be crushed into nothing.
Even if you werent crushed, black hole would contain so much energy...
it'd shock you to death

Yeah, it's a white guy who hasn't taken a dump in a few years and busts out the Turbo Lax



Do you know how many topics have been created about Christianity? A shitload more than this!

Anyways, if you went into a black hole and somehow in hell survived, you would be blinded. It absorbs light and since it's gravity is so high light can't escape, so there's alot of light bouncing around and trying to escape, but it can't so you would see nothing. Just white everywhere.

ADDITION:


Gotta comment on this...

A star is transformed into a black hole when it implodes on itself. This implosion has ALL the matter a star has, but compressed into a tiny ass space. Then, you've got all this matter compressed and very dense so it has a huge gravitional field and starts pulling stuff towards it, steadily increasing in size.

Read Frozen Star (not sure who the author is), there is a thing in there that a blackhole 1 meter in diameter would only increase a centimeter if all of Terra (Firma) was sucked in it. So far we have no proof of it puncturing space open, but we have noticed that an object it couldn't grab was all of a sudden grabable when a star was totally consumed, therefore it is increasing in size, if it was a hole, then the more stuff sucked in, it would decrease in sucking power.
