Blackholes

[sinkoman]

I'm hoping somebody can explain this to me as layman as possible.

Every time I see a definition of a black hole, my mind just can't comprehend what's being put into it.

So, what i've been satisfied with settling with, is that a blackhole is just a loophole in the universe, where the laws of physics are essentially traversed, and everything just becomes something (that's where my mind starts to falter).

Wikipedia says that it's matter so dense that it falls into itself, but that STILL leaves me with the "how is that possible" feeling in my mind.

When stars get too weak for their own gravity, they crumble into themselves and become a super dense "hole" that sucks in everything that approaches it, including light, which is why they're black.

Also because of special relativity and because it has such a strong gravitational pull, the speeds get ridiculous when you're sucked in a blackhole in wierd sh it happens.

But that means matter is sucked into... UNmatter.

See what i'm saying.

WHAT exactly is a black hole? You explained (very well I might add) what CAUSES them, but WHAT is one?

 

[pvtbones]

it's like a vacuum cleaner the size of a pea (can be larger or smaller) the matter is still there it's just been squished very very tiny.

Thankyou.

No longer does my mind explode.

My original thought was that a blackhole was just a giant loophole in the universe that is neither flat, round, square, but is just that, a space in space, a loophole in space where all matter escapes, much like you'd escape from a contract.

Then I would start screaming "BUT WHERE THE FECK DOES IT GO????"

THANKYOU.

EDIT: BUT

If the matter is squished very tiny, then why can one not see the matter IN said "vaccum cleaners"?

If it is strong enough to absorb light, yet still contain it, then could you not SEE the light within the blackhole?

black holes suck

 

[madog]

What's with all this talk about how you could travel through a blackhole except you would turn into spaghetti or some shit like that, or is that wormholes.

 

[TheSomeone]

Well really we don't know, we don't even know if they really exist (although we have a good bet that they do). But all the matter just keeps on getting sucked in and the gravity is so strong that it keeps crumbling onto itself and becoming super dense.

The thing is, to the outside world, things never get fully sucked into the black hole, because of relativity and because the objects are constantly approaching the speed of light, they would just seem to go slower and slower.

Black holes aren't actually holes at all, they're matter, just matter so dense it sucks in itself.

I think your real interest lies in wormholes: http://en.wikipedia.org/wiki/Wormholes

These are rumored to be the center of blackholes. I think it's stupid personally.

The way you "see" is by processing light that hits your retina.

 

[nofx]

While on the topic of physics i just wrote a paper on superconductivity not that anyone cares) but feel free to discuss it ill be sure to chime. black holes ot me seem so pointless no real way to help society now.

I already looked up wormholes. They make complete sense to me.

But Blackholes, oooooohohohohoho, NO. Those stupid little mother****ers are just THERE!

Is it safe to settle with the definition "a fecking huge loophole in the universal laws of matter in which all matter escapes"???

 

[madog]

How can we take pictures of black holes if the light gets sucked in?

No :-/.

More like "something with such a big gravity nothing can escape from it."

Not even light, hence it can't bounce on it and back to your retina for you to see it.

You can't, you just see blackness.

Now that I recall, I remember seeing blackhole photos where all you could see was all this matter concentrating itself into a single point, only there was NOTHING at the point.

Kinda like a Direct X shader that lead to nothing.

But really though, what happens to this matter when its trapped? Does it become UNmatter?

Okay, the thing about matter concentrating itself into that point:

The thing is, you'll never see the matter go into the point because of this:

They accelerate so close to the speed of light, and keep accelerating, yet the speed of light has to stay the same for both observers or the law of intertial reference frames is violated, so time reajusts and slows down nearly completely for the matter going at ridiculous speeds, this is a whole other subject though.

In the middle there is the entire star collapsed onto itself, so it's still matter.

 

[madog]

Up to how far can these black holes suck things in. Is there a certain point at which if you cross over you zoom toward the middle at a million times the speed of light.

That's the whole thing about the speed of light being the universal speed limit. Agreed, a whole different subject, but I understand it.

So yes, it is like a pea that everything squishes into?

 

[TheSomeone]

Yeah.

You can't go faster than light lol.

Wtf? Time never stops. It is always going. Even if everything is stopped the time is still passing.

Madog:
it doesn't completely stop but does slow down in relation to us observing the object in question.

 

[Pesmerga]

No... relativity, man, relativity.

 

[madog]

Madog:

True the rate slows down, but time itself does not slow down. If you watch movie on fast foward seconds still pass the same way as they did watching it normally. The time it took to watch the movie will be shorter yes, but seconds still passed the same way as they did before.

 

[Pesmerga]

That's not even close to the same thing. Time isn't some all powerful super-god like constant.

 

[madog]

Well if there was a start to time it just keeps on running. I guess it could be different in an alternate dimension but what the hell, I'll just wait for someone to deliver the best scientific explanation that is simplified.

 

[TheSomeone]

Lol madog

diz too complicated fo yo brain.

Wait until you learn about Special Relativity.

 

[madog]

You don't know how intelligent I am and likewise, I don't know how intelligent you are. So let's not make any assumptions eh?

 

[sinkoman]

Judging by the way you talk I would assume I have a much greater chance of grasping this concept then you do.

You seem to be creating your own universal laws of physics to build your own knowledge of this on.

I mean, ffs I haven't even taken physics yet and I get it :/

 

[madog]

I do get it. I was changing that post so I didn't sound so judgemental. I don't make my own lawas up but I do question the ones in place. If no one did we wouldn't discover anything new. So please, let's not play pin the shit on madog because I have had enough of that game.

 

[Raziaar]

You moron humans don't even know all the mysteries of your own ocean, how the **** can you solve time?

Puny earthlings.

 

[xcellerate]

You can't go faster than light lol.

clearly you've never been in a chipped 1.8t.

Take like the US naval fleet and then sqiush it into a marble and that's close to what you'd get with a blackhole.

It must create a partial vacuum to be a black hole.

[Ikerous]

Forums + physics = stupefying

 

[sinkoman]

And here comes the spam...

But yeah, I think I get it now.

Everything just moves over and gets smaller for the other stuff to fit in, and everything just keeps getting infinetly small to get int here.

Nvm, new question.

How long does this process last before something shuts down these black holes? If nothing ever destroyed the black holes, then isn't it possible that the universe will one day be nothing but blackholes scattered all over the place?

Which begs the question, what of when a black hole sucks another black hole into itself? Does it create a supervacuum? Is the even possible, concerning the laws of physics and the speed of light?

 

[99.vikram]

Well, according to one of Hawking's earlier theories a Black hole is a region of near infinite density (can never become infinite coz of the Heisenberg principle). It is formed when the repulsion of matter particles is not enough to counter gravitational pull. This then forms the event horizon, beyond which light can't escape.

How long does this process last before something shuts down these black holes? If nothing ever destroyed the black holes, then isn't it possible that the universe will one day be nothing but blackholes scattered all over the place?

These event horizons often break up energy near the surface into particle-antiparticle pairs, of which one might get sucked in while the other escapes. Black holes ultimately "die" after they lose a lot of energy this way (causing gravitational pull to be weakened), and they then explode and crap.

Which begs the question, what of when a black hole sucks another black hole into itself? Does it create a supervacuum? Is the even possible, concerning the laws of physics and the speed of light?

Of course, no one knows for sure. But I think the two black holes merge to form a new black hole, the same way bubbles or water droplets work.

 

[Gray Fox]

So if I understand it correctly a black hole is not a singularity, otherwise it wouldn't grow. If it can grow then it most be just very very densly packed matter.
And what about that losing or radiating energy thing, if a black hole can even prevent light from escaping then how come energy still radiates from it, and if we could observe and translate that energy in to a picture just like we do with sound and a sonar then could we in essance take a picture of a blackhole with it's internal structure visible.

 

[short recoil]

A black hole is exactly the density of a matter travelling at the speed of light in a vacuum, it's basically ****ed itself out of existence.

But remember something, there is no gravity if there is no matter.

BLACK holes are real i an posting from my mobile phone

Edit:From my PC. Sure Black Holes exist, from what I understand it's just a very small thing that's extremeley dense.

The singularity is that point in the black hole in which matter is compressed to an infinitely small dot. So, a singularity and a black hole are not two separate things.

As far as I know black holes slowly "evaporate". The eject once in a while an atom, and they keep doing it until the gravitational well of the black hole gets weaker and weaker until in finally vanishes.

 

[Greatgat]

Technically, it's the smallest thing allowed by the universe, at least according to what we know of it. Hey, didn't they just discover that the supermassive black holes, like the one at the center of our galaxy, are the reason spiral galaxies exist? They're supposed to act like a gravitational anchor. Yay black holes!
