"Don`t only suck in material, they also blow it out"
"Nothing can escape once it`s within the radius of the hole"
"So black holes aren`t entirely black"

Wow, I think they purposely said some of this stuff like they did.

"It`s the only theory that can take you all the way back to before the Universe`s creation, and the only theory that can express EVERYTHING in a single equation." - Legacy 15

I can express everything in a single equation:

n/0=reality

Everything is imaginary. Every theory is right. Every theory is wrong.

You could say this page is made up of a bunch of pixels that are placed in such a fashion as to display the bigger picture this way, but I could just as well say it is made of triangle designs meant to do the same thing. We`re both right, and we`re both wrong.

Accept that reality is. That is the real "universal truth".

Or is it?

Legacy15 The math does not check out on string theory, mainly because the mathmatics is so amazinly complex that there is a problem trying to find out which equations they have to use in the first place because they have to actually determine how many dimesions they are working with. See physisit Brian Greene`s book: The Elegant Universe.

And it seems a lot of people here think a black hole is actually a hole. It is not, it is a solid mass of immense density.

Vagrant and Shootist - you are both confusing Mass with Density. If our sun collapsed into a black hole, it would not become more Massive, it would only become more Dense.

And opie, if you see this, the reason why matter is completely obliterated is because it is turned 100% into radiation. Its like when there is a matter-antimatter reaction, both lumps of matter are completely destroyed and you get the equivalent in energy.

All of this follows relativity by our good friend Einstein and his beautiful equation E=Mc^2. Forgot the Lorentz factor, but thats for another day.

And this follows to your question eleutherarch. When all matter is completely destroyed you no longer exist. There is no information left to find because all traces of what went into the black hole are gone. So if I throw this 150 lb. guy named Reginald into a black hole and 150 lbs. of chairs into a black hole and you could somehow look inside, you would never be able to figure out what was thrown in, a Reginald or the chairs.

The math behind string theory is extremely complicated, you might as well compare it to a caveman trying to take a triple integral via integration by parts.

When string theorists run into a problem, you know what they do, they add on another dimension to explain it. Right now we`re at 11 dimensions, and in 5 years we`ll probably be at 63.

Seriously, string theory is a giant crock. The universe doesn`t need to be explained by over-complication. I`d like to cite Occam`s razor in this particular instance. Plus, Cern is also looking for the Higgs Boson which would explain inflation. Betcha 10 bucks we find that before the graviton.

To the video, although I couldn`t listen to it, I think from the comments I saw enough to know what was in it. Vagrant - it would be possible for a black hole to go down to the a solar mass if their is Hawking radiation and black hole evaporation. These would have to be isolated, i.e. no matter infall, and it would take a long time, but it is possible.

I dont know if this has been said yet. But that was the most retarded thing i have seen (for the one certain section): A black hole would wipe out earth. Its so massive. There is no way a black hole would have the same mass as our sun... thats just stupid.

It would be cool if the whole theory that going into a black hole would send you off to some other dimension or something. But I don`t get the whole thing about going into a black hole and just not existing.

^ VERY true. String theorists have no way of verifying anything apart from a whole lot of math; and the graviton is not a string theory only prediction.

I saw Edward Witten speak at my university; it was eloquent and all, but the amount of math jargon the theory hides under means that no one but string theorists themselves can sufficiently evaluate the theory. Ergo, when you can falsify that theory and claim it false, you are often in too deep for the falsehood of the theory to benefit you.

There are TONNES of problems with string theory and they are indeed in the minority.

"Most theories would say that the matter absorbed by Black Holes goes to another dimension (i.e, string theory, now the most commonly accepted theory for just about damn anything. It`s actually really cool.)"

Wrong. Hawking has a theory on this, but the original multiverse theory did not insinuate black holes. Also, string theory is NOT the widely accepted theory, string theorists are in the minority. There is testing to be done for string theory, but we are years away from the required nrg levels

actually, most theories do NOT say that the matter that enters a black hole is transported into a different dimension. that theory was once believed by Steven Hawking, but he later changed his hypothesis. It is widely believed that the matter that enters a black hole is crushed by the immense gravity into a very small size

ZMDalph has a comment, as paul green describes: what DMZalph is going to say is: what about light holes?
ZMDalph has another comment, as paul green describes: ZMDalph thinks that this was semi interesting

The reason that we should be glad that black holes exist is that they are what keep the galaxies together. At the center of every galaxy is a black hole, including ours. However, all the billions of stars in the galaxy, including ours, are far enough away from the black hole that their own gravity keeps them (and us) from getting sucked in.
As for string theory, although there isn`t any concrete evidence, the theory makes sense, and it is possible that evidence may soon be found. CERN is building a particle accelerator; the biggest in the world. With this accelerator, scientists hope to catch glimpses of certain sub-atomic particles that would be necessary for string-theory to be true.

@ theshootist - Actually, that`s not true. You could, theoretically,have a black hole with as much mass as your house, or even your fist, or even an atom. The reason black holes tend to have so much mass is that having so much mass is the only natural way for something to collapse in upon itself, what with gravity being so weak and all.
Black holes, contrary to common misconception, don`t have to form from stars. They just form from a enough mass in close proximity to collapse upon itself. That`s why we have super massive black holes at the center of galaxies.
As a disclaimer, I would like to point out that I`m no expert in this field, so everything I just said could be completely wrong.

This video did clear up a few misconceptions I had about black holes, though. I had no idea that they actually expel the majority of the matter that comes near them.

as long as the black hole has the same mass as the sun....the whole freaking point is that it has millions of times the mass of the sun...one of many gripes i have about this video

I know. I think its charming and sexy.
Sentences are build in another way in swedish.
Not as notable like some asian languages.
But it was more a train of thought text.
But i think most of my points got lost in translation

"(i.e, string theory, now the most commonly accepted theory for just about damn anything. It`s actually really cool.)"
Tis rather interesting that it`s become such a widely accepted theory as there is no evidence whatsoever fo it.. all the evidence for it comes from if other theories are true.. it involves a lot of `if`s and relies on presumed possible knowledge. Most theories have at least a little more evidence for their existance than string theory. It makes sense only if you assume all the seperate components of it are true.. which they`re not as they`re only presumed.
Things don`t dissapear in black holes.. they become a part of it.. but then no one knows so actually everything that goes in could actually become a cabbage for all anyone knows.

ah. watched the other link. it agreed with what i put. but it did mention "some theorize that entering a black hole could transport you to another dimension" or some jazzz like that.

Black holes from when a star 3 times the size of the Sun runs out of hydrogen.

Told me most of what I already knew, but Black holes still amaze me. The thought that some giant sun turns into such a thing is mind-boggling.

i always thought that black holes were supercondensed stars. and that their gravity was so effing immense that when matter got sucked into it the gravity wouldnt let it go. including photons and all the parts of the electro magnetic spectrum. ive never heard anything of "a different dimension/ majically transported to a white whole" but then again. i havent taken astronomy/ quantum or dimensional physics. just sayin.

hmm, im not bored anymore.
I was glad I`m in this universe, but then I thought what am I. then I started to think of what are other people, then i got sad..
But I got happy again when i thought of porn, ok i made that upp. but on second thought..
Naaaaah...or. maybe. hmm. well.

I came (no) to the conclusion I like porn.

BUT, This is not the time for porn.
drawing ? nah.
playing some mmo....tempting.
what would i gain, nothing of importance.
what would i lose, nothing of importance.
OH MY, what do i gain by sitting and wrighting here. NOTHING.
But it kinda comforts me, that if you have read all the way to here, you have gained NOTHING.
But then again im guessing its like 1 or 2 ppl at max who read this.. well thats crappy.
as you are probably some dicks who think robots will take over the world or you might be religious, and that totally sucks for me.
but wasting the time of people i dont like might be good.
But i dont want chistians and robof

Legacy15, how can something show up randomly?
I don`t really understand that whole.. teleportation.. thing...

Things move, not teleport.

Good God, I`m like, physics-close-minded. D:

I don`t, and haven`t ever, understand what a black hole is. How does stuff just.. go? Isn`t one of the basic principles of physics that matter can`t just not exist anymore? There is no Delete key in real life?

I`m so horrible at physics...
