whats the deal on the Black Hole? where is it located and what happens when you enter it?

Question

how do we know that a black hole is even a black hole and that its not just a wide range of swirling energy?

Answer 1

Finding a black hole is hard, for obvious reasons.

The chief characteristic of a black hole is gravity. It should bend light around it. However, we have to be close - like we are close to our sun - to measure it. We could also look at objects near the hole and compute gravitational effects on it.

Gravity is so intense that it varies by the meter. Your feet would be pulled down faster than your head, so you would be extruded into a piece of spagetti, then your molecules and atoms torn apart in a puff of X-rays.

Answer 2

Well, if you see a perfectly (or nearly perfectly) black round thing in the sky (through a telescope, of course, and a very powerful one) it is very obviously a black hole, since it is the only known thing in the universe that will suck light into it and not emit any. Besides, a black hole has high gravitational fields, so it will distort light around it, so when you look near a black hole, you see slightly misshapen and deformed stars as an effect of the distorted light.
As for the possibility of this "swirling energy" you're mentioning: what exactly is that, why does it "swirl", and why would it be perfectly black?

Answer 3

Where is a black hole located?
Think of it this way.
Black holes suck light into 'em, thus it is completely dark.
Space, where black holes are normally found, are also dark.
Thus it is hard to find a black hole, though if you're on a spaceship and it suddenly gets sucked to some blank point in space it's most likely a black hole.
Currently, it is unknown what happens if you go into a black hole. Obviously because people who go into black holes tend to stay there.
Personally I believe that if you go into a black hole you will just get sucked to it's centre and all the gravity will atomise you into a couple of protons and electrons.

Answer 4

OK a black hole is in theory "not rumor" a concentration of matter that is so dense that its gravitational force is extremely powerful and any thing (matter, light or any other electro magnetic radiation) is pulled into it. Unlike its name it is not a hole its just a hole in our view. This is also how we know it exists, because when something passed behind one from our POV it "disappears" because of the light it gives off is pulled into the black hole. All of these things being pulled into it just be come more super dense matter there for they slowly grow over time. All of this seems very impossible to imagine so people say that its has to be a door to another place because black holes grow so very slowly, the reason for the slow growth is due to simple physics. All atoms are at best about 97% empty space and even the most dense compounds we know is about 60% empty space between atom and even more space between particles of the compounds therefor the possibility for compression is extreme if you had a great enough force to remove the empty space. So even a huge planet can be compressed to the size of a beach ball if you could remove the empty space. Now this is all theory but is the excepted theory by the physics world.

Answer 5

I dont know, thats something to wonder about, huh? All of outerspace is black, yet somehow we're able to see a black hole. Hell, I cant even see a green hole in the ground during the day. But, since no person has obviously ever been inside one, there had to have been a satilite. You'd think it'd have to be real close to snap a pic for the guy at NASA to see. And then it'd get sucked in there. Maybe that /was/ what happened... Cool.

But the only way to find out whats inside is to wait until a new one pops up in Earths orbit path. Hope we can take our air with us. Then again, we might freeze to death. Still, that would end global warming. Not that there'd be people around to notice.

Isnt it weird to think there's a hole ripped into outspace? A frickin hole. Thats so weird. I wonder if it has two opened ends, or just one. If theres just one, theres whole lotta **** piled up inside it, and I wonder if it'll eventually get filled up. And if theres two open ends, where does the other end take you? To another universe?

Now I wonder what other universes are like. I bet we're not the only planet with life. Maybe other life just isnt like our own. Actually, I know its not. They'd have to be ALIENS. They'd probably only be as evil as people are. Then again...

Answer 6

Without trying to razzle dazzle you with mind bulging formulas , I'd rather give it to you in layman's term . when a star collapses into itself , and it hast to pass the Chandrasekhar's limit , it will form a black hole which will draw anything near enough > well umm in space a few million miles away is considered back porch , I hope you get the picture < into itself , one of the evidents of an existing black hole is the gamma rays which are emitted while objects are devoured by the hole . center of black hole is so dense and the gravity force is so intense that all the laws of physic will collapse there , which means we don't know exactly what's going on there , we just speculate based upon some scientific evidences , THE OPERATIVE WORD here is speculate .check the source so you will not be miss led by guys like me , happy hunting .

Answer 7

There is not one black hole there are millions matter fact we have a black hole in the center of our own galaxy. As of right now not much is known about black holes other than whatever comes close enough to it is sucked right in. Nothing can escape its gravity not even light. And that is the reason why it is called a black hole because all the light is sucked right into it which makes black because no light reflects back. (HAHAHA the last part rhymed SWEEET! lol)

Answer 8

Black holes are most likely quite numerous, and most stars with a mass over 3 times that of the sun is likely ot turn into one after going supernova. Estimates is that there should be a few millions in our galaxy alone.
Then, there are the supermassive black hole at the center of (most likely) each galaxy. Since galaies are in the billions in the univers, that makes quite a bit of them.
But most of them are pretty far away (space is called space, because it is mostly empty space), the closest one to us is 1600 light years away -- see link.

As to what happens when one crosses the event's horizon, well, anything is falling in and accelerating and, assuming that any obeject would be able to survive the tidal effect (that is the difference in gravity between the front and the back end of whatever object -- this differential in accelerative force would tear up a human being -- I am not kidding you -- as your legs would be pulled down with a force many tons stronge than your ehad (assuming you enter it feet first) and you would be stretched and broken down to induvidual cells or perhaps even molecules. Then, as each molecule is accelerated to relativistic speed, those will emit radiations of a power comparable to that of a nuclear bomb; and time will essentially stop, because the theory of relativity says that times slows down as one gets near the speed of light. Actually, falling in a black hole would pretty much ruin your day.
As to how we know a black hole is a black hole, well, it is because it bends light of more distant objects, in a way that shows it be be extremely compact and highly massive. Or that it is absorbing matter from a nearby star or gas cloud.

Answer 9

Any huge mass majority of them stars when having very huge mass becomes a black hole. Higher the mass means higher the gravity so when mass very huge the gravitational pull is so powerfull that nothing can escape from it niether light or escape velocity of the star becomes greater than light .The size of black hole is found by finding event horizon of it,event horizon is region in black hole beyond which light cant escape.

Answer 10

first question: a black hole is a place in space that has such a deep gravity well that nothing can escape once it passes the event horizon.
second question: no one knows for sure, just theories on where they are.
third question:the gravitational field crushes you to the size of an atom, you die.
fourth question:since not even light escapes it can not be seen directly and appears black.
fifth question: that swirling gas, matter, and energy have to be swirling around something.
