Black holes..

[RageAgainst]

I was just thinking about this... I heard Black holes are so dense that their gravity field is stronger than nuclear forces holding nuclear particles togheter (wich is pretty fucked up.)
For example, if I would change the sun into a black hole by magic, we'd all dismantle and our particles would head for the black hole at speeds close to the speed of light. (tell me if I'm right)

Now, I'm not totally sure but I think black holes can attract stars and revert them into basic particles, wich is a pretty cool thing to think about. Anyways here's the point:

If they constantly attract stars and constellations, their mass keeps growing in an exponential way because their gravity force field keeps strenghtening (in an exponential way too). So eventually, the black hole will attract even galaxies, and after a relatively long period of time, say billions of years, there would be nothing else in the whole universe than a single black hole...

Is that crazy thinking or could it actually happen?

i'm not too sure but black holes are fucking amazing:thumbsup:

[Jane Deere]

They are pretty amazing, I sometimes find the concept of black holes too hard to comprehend.

[Acid_Corona]

It's crazy talk. A heavenly body exerts a gravitational pull so long as it is still around. Once the black hole has claimed it's doomed neighbor, the gravitational field it had it lost forever.

The proof is in that scientists believe that the center of every galaxy has hundreds of black holes. Some scientists even theorize that these central concentrations of black holes hold the galaxy together, much like our sun holds together our solar system.

If there are hundreds of black holes in the center of each galaxy, what would happen if two black holes sucked up one another?

i may be wrong, but i think that those scientists actually think that there is one so called 'super massive black hole' at the center of every galaxy. and yes they do theorise that the gravity of this keeps the galaxy together.
oh and what would happen if a black hole gobbled another black hole? some scientists think this is how a wormhole is formed.
black holes are weird as hell though. its really weird to think that it may be true that eventually everything will be in one big black hole.

[dull_bullet]

a black hole doesn't have infinite range, dude. Most galaxies, in fact, have a black hole in the center of them, which is why all these stars are clustered together ina galaxy int he first place. Once the stars nearest the black whole drift to close they get sucked in, and are turned into a singularity.

as for the black hole sucking in another black hole....i have no idea. I would think that they would just orbit around one another, never really thought about what would happen if they get sucked into each other....

[Margrette]

so is the black hole so strong that it makes nothingness in the center ? or is there a fucking ultra-concentrated ball of crap in the middle...if so, what would happen is something caused a ripple in the gravity (stopped spinning momentarily, or slowed down) would it explode and shoot a bunch of light out ? or is the light DESTROYED and nothing comes out ?

[PeekItUp]

Black holes are, simply put, dark stars. Their gravitational pull is so strong as to overcome all of the light that they produce, pulling the light back in. This means no light can leave them, and any light that strikes them is absorbed, so there is absolutely no way of seeing them...
But they are still stars, in a sense that they engulf things. If two black holes where to suck each other in, they would simply form a bigger one.

Singularities are thought to exist within black holes, though it is theorized that there are special singularities that do exist outside.

Indeed gravitational force from any mass, including black holes, extends for an infinite range. Simply take the product of the two masses to be detemined, divide by the square of the distance between them, and then multiply by the gravitational constant. This force is extremely small, but it extends to an infinite distance and is always attractive.

[Darklight]

my understanding of a black hole was that it was a collapsed star or other such dense matter that has now become so dense it creates a pocket in in the universe(on the fabric theory of gravity) so deep it bottlenecks at the top like clasping a marble in a cloth at the top which pulls everything even light into it.. and everything that goes in adds to the mass only making the hole stronger...

[FuckedOver]

if black holes suck everything in, and there is one at the centre of each galaxy, How in hell is the universe expanding, shouldn't it shrink?

also, do black holes move and suck things in as they travel, or do they stay put and grab things as they pass ? Now there's a thought. I only hope someone is intelligent enough to come up with the same answer as me!

Maybe they dont grow in mass. Perhaps they're just like a funnel that swoops up everything in its vacume and launches it to another universe. We will all end up in a newer universe somewhere.

[Spikey]

*WHICH

Well, maybe, it could happen.
But, what would happen if two black wholes of equal strength came near eachother?

[Zickddot]

Actually I was reading and it said they don't have an infinite range of...sucking. Scientists predicted that if our sun were to become one, it'd have a range of about 4 meters. And yes, they are stronger than the nuclear bonds that hold together atoms. It's said that all matter in them is seperated by element. Also, you are sucked in at exactly the speed of light, not about. So no, you can't escape no matter how fast you go. You won't see it coming either, they are invisible and cause sudden death, not only that, but you'll just disappear, nobody can see you go in, you just *SHOOMP* in.

On discovery, they said that eventually after all the black holes suck up everything, they will begin to suck up eachother making the black holes non existant.


Except that was a couple years ago, so things could have changed

[Zickddot]

I don't think that can be true. Newton's Law of conservation of mass and energy states that: Energy nor mass can be created, or destroyed, only misplaced and transformed. Matter will always be there, you can't make it go away.

[Repth]

its hard to understand because our human minds are so limited. Just like no one can really understand the entire "god was always there" concept, because everything in our universe was created so we cant even comprehend this topic.

Since a black hole is so radical and theres nothing like it on our earth.. and because space travel and exploration is so limited, we really cant even imagine much about it.:sad:

daomn thats confusing..

[Broken]

A black hole is simply an object in a system that has a mass that it's G is greater than C. Do they exist yes, but is the system closed? No not as we know, it's an open system. Dark Matter is much more instresting.

[FuckedOver]

Well, the fact is, no one knows, no one ever will know, because no is dumb enough to get close enough to one to find out.

[White_Trash]

Ok I seen this thing on blackholes and had to post something me and my friend thought about. Now my friend is like smart as hell so one day I got board and asked him if he knew how to put a craitor in a black hole. Well he sat for about 20 to 30 minutes and then figured it out. I swear his mind never stops. Anyway he had said if you got something the size of a truck to travle 98% the speed of light, and have it go directly though the center of it what would happen is the truck would go through into the black hole and that side of the black hole would grab onto (due to the amount of gravity) the truck and pull on it in a cone form causing it to dent and look like what happens when a plane breaks the speed of sound. That was the closest thing he could think of to put a craiter in a black hole is that sweet or what.

[FuckedOver]

I do know that a black hole is still a sphere

I was just looking for that link. So here's a black hole FAQ (so you can learn about white holes too- I bet that got your attentions.)

http://cosmology.berkeley.edu/Education/BHfaq.html#q10

[FuckedOver]

here's a thought,

what if the white hole is actually the other end of the black hole???

[White_Trash]

You know what I think. This man has a sick and twisted mind to come up with some strange shit like that. I say that is a Q. of imagination... or drugs:confused: well what ever the case maybe I think that is a damn good Q. I say my friends Idea was totally awsome in my last post.

[FuckedOver]

imagination and alcohol

[Spikey]

Interesting Zick. What if someone was traveling the speed of light away from the invisible black hole? That's disturbing, the fact that you just disappear. I didn't know that they were invisible. Just curious, what's at the other end of a black whole?

[FlipTheState]

Newton's laws of physics may or may not apply. Remember that there's a whole scientific discipline called Theoretical Physics...as in theories about things we can't prove yet.

In line with the theory that there's a black hole at the center of every galaxy, there's another theory that states this black hole exists within the center of the major central star around which everything in that galaxy orbits. i.e. our Sun would have a black hole in its center and the light and heat are the effects of gasses being burned off as particles enter the black hole.

I thought that was interesting.

[onyx]

Ok, lemme set this all straight. Seems that there's a lot of random, and unsubstantiated theories floating around in here.

Theory #1: Black holes are invisible.
Truth: Technically no, you cannot see a black hole. This does not mean you cannon see the visual evidence of one. As material is attracted towards a black hole, it begins to orbit the black hole at an constanly increasing rate. As the material gains kinetic energy, it will begin to bleed some of that energy in the form of light of all wavelengths (ie: visible, gamma, uv, x-ray). The closer to the Event Horizon (the "surface" of the black hole), the higher the energy given off by the doomed matter. The "invisible" part of the black hole is the event horizon, which is the point where it's gravitational pull becomes strong enough that photons can no longer escape. This is why you cannot see the actual black hole.

Theory #2: What black holes are made of.
Truth: The obvious answer is that a black hole is made up of all of the material it as consumed, as well as it's original stellar mass. The real question is what happens to the matter that crosses the event horizon. Beyond the the event horizon, along with being the visual edge of a black hole, is also the point at which conventional Newtonian physics break down. Matter and Energy cease to be seperate manifestations of a single existence, and form... well, that is truly unknown. However, it is known that this material does not cease to exist, dissappear, or get transported to another place. It can be observed that the mass (and subsequent gravitational strength) of a black hole does, in fact increase as material is drawn in to it.

Theory #3: Black holes collide
Truth: This is actually very simple. If two black holes were to come close enough to be attracted, they will simply merge into a single, larger black hole. Imagine two drops of water on a counter-top. If you were to push the beads of water together until they touched, they would combine into a bigger drop. Admittedly, the collision of black holes would be much more grandiose and exciting than the drops of water, but you get the idea.

Theory #4:White Holes
Truth: The existence of so-called "white holes" has never, and most likely never will be, proven. Some suggest that at the center of a black hole, there is a wormhole or portal effect that funnels matter from the black hole to a point source of energy elsewhere in the universe. This is FALSE!!! Black holes are proven to retain the mass that they entrain, therefore, they cannot be conduits to mass/energy faucets in another location. If they did, their mass would never change, or at least would not be proportional to the amount of material that has entered the event horizon.

As far as the structure of black holes, the boundary at which light can no longer escape is known as the Schwarzchild Radius. This is the point at which the escape velocity due to gravitational forces, is greater than the speed of light. Within the Swarzchild radius, at the center is the Singularity, at which matter reaches such a density that it is considered infinite. In theory, as matter approaches the singularity, it's velocity continues to increase, as it accelerates to the gavitic center. According to Albert Einstein, and verified by modern physicists, as velocity increases, time begins to slow down. Also, the force of gravity has a direct correlation between mass and density. Seeing as the singularity is of unkown (but obviously extremely large) mass, and near-infinite density, gravity near the singularity becomes a near-infinite force as well.
So, imagine that you could somehow cross the event horizon intact, and observe what was happening to you, you would never find out what the singularity was like. As you get closer, gravity gets stronger, so you accelerate more. As you accelerate, it is proven that time will move slower for you. Since gravity at the singularity is infinite, so you acceleration will be too. Infinite acceleration means infinite speed. Infinite speed means time stops. THEREFORE, you can never know what the singularity of a black hole is like, because you will never reach it.:)

[Stoopid Monkey]

Welp, I'm a nerd that likes to learn new things all the time but after reading this whole damn thread...my head is throbbing. Ouch. Black holes kick my ass, plain and simple.

[teh anarchist]

Wow, I think onyx is the first newb who has made a competent, relevant, and grammar-error-free first post. Repped.

[dull_bullet]

stuff.

Damn dude, are you an astrophysics major or what?

That's what you could've said. But, the other stuff was a mouthful of interesting facts. :)

Brilliant post onyx. Well done indeed.

time does not stop, it is only the illusion of time stopping!

i thaught that black holes commpressed you and twisted you slowly so that it is as though time is slowing down
but no body knows whats at the center
