I didn't think anything could escape the gravity of a black hole.
Right? |

Not a true space black hole, but wonderful imagery nonetheless. |

hey. read the comments people. its a computer simulation written by some (amateur) guy. this is NOT a black hole. its just called black hole. |

IceUck I agree, this is almost certainly a computer simulation. Space isn't 2D, you would see a star at least behing it. Not only that, the event Horizon is the point where nothing can escape, where the force pulled on mass is stronger than the speed of light and the only way to escape it is to impossibly go faster than the speed of light. So to see this matter/radiation going in and out and around means this isn't even a good simulation. |

For all the folks pointing out that you can't see a black hole...No, you can't see the black hole itself (whatever "it"--an infinitely small point of infinite density--is), but the matter that goes swirling into it gets hotter and hotter, and gives off all kinds of radiation before it passes into the event horizon. If the black hole is feeding on nearby stars or whatever, you probably *can* see the white hot shell of gas and dust around it. |

I call shenanigans. This looks suspiciously like a computer simulation (of something else). From what I've seen and read about black holes, the motion and speed are all wrong. Plus there's no way we'd get such a detailed, sharp image. That thing'd have to be in the solar system for an image that good... |

how come you can see colour if black holes suck in all light around it? |

People, black holes dont lead anywhere like portals. They crush matter into infintely small paritcles and eject the rest into space in the form of jets, which can reach light-years in length. |

where do stars go once they go in a black hole? |

People don't seem to realise that blackholes have an uncanny amount of gravity, you can't see the hole, but you sure a hell can see the poo it's gonna eat. |

you cant see black holes, but you can see the stars orbiting it and you cant see hawking radiation either because its not in the visible light spectrum (plus if we did see it we would be dead)and light can be shown by stars that are between us and the black hole because the light doesnt go near it, just straight to us |

lawl!!"Black hole is an application made with Processing. I have been working on it for few last months.
Making it I had to learn some OpenGL and remind my math backgrounds, but I hope it was worth it. At the beginning I wanted to create a dark sphere with dynamic glow. Using a OpenGL substractive blending and simple math transformation I created a resizing glow similar to cloud or nebula."
http://blog.arsthanea.com/2009/01/05/bla... thats from the guy that made it. |

i do not think this is a black hole i think this sar is just collappsing, the reason i say this is because due to the fact no light is showed in a black hbole, so in that thoery we cannont see a black hole except with a negative phote in withch case it would be black, no if we folow this theory even further we would not see the stars behind this and once they got close enough they would all together disapear. as ice fire said "Im no expert, but i don't think that this is a black hole yet. I think this is what is called a red giant which is a star that is collapsing and will make a black hole. And i dont think we can see black holes we just have ways of calculating where they are." which i am in total agreement with. so ponder that every one. |

Yes I know r stands for the distance between them. I was just using faulty logic, thinking that r was measured from the surface, not the center. And yes, I still think this is fake. Going back to the point, if the sun turned into a black hole, it would not suck the solar system into it. In the equation Fg = Gm1m2/r^2, the mass of the sun does not change, it just gets denser. None of the other variables change either, so the earth (as well as the other planets) would just keep orbiting it. The only way the mass of the black hole could get bigger, is if it absorbed something and the only way that would happen is if something gets on a collision course to hit it. Usually, only comets and asteroids will collide with celestial bodies, so the mass will only increase by miniscule amounts (compared to its total mass). In conclusion, black holes emit hawking radiation, and if it doesn't absorb anything, they disappear. |

Hopefully everyone will now go through wikipedia to read up on black holes and whether or not we can "see" them. |

i dont understand what we are looking at here...
i was thinking when i read the description there would be something getting gradually sucked into a black hole or something along those lines. i heard things look like they stretch when theyre getting sucked into a black hole. but idk. im no science major, but i dont think this looks like any description of a black hole ive ever heard.it looks more like an animation, of like some kind of a star or something, just kinda..being a star. flailing around and stuffs. O.o

Call animation, hardly probable though yes? |

How is this video even possible? The gravity a black hole has will prevent anything from leaving it, INCLUDING LIGHT ITSELF. So even if it where to "spew out" plasma, we wouldn't even be able to see it. I call fail as well. |

Having now actually seen the video, yeah, that's not what it would look like. The singularity is always either a point, or a line. I understand the spinning was rotating the camera, but it would look considerably different as you went around it. I call fail :( |

"do black holes even have rotational velocity? looked like a black hole sun, woontcha come, lol idk why i thought of that..."Depends, is it a rotating black hole, or a non-rotational black hole? I guess a rotating one, would have to, by nature, rotate at a very real speed. |

Also, particles that haven't reached the event horizon, are still moving around and bouncing off each other, they can reach escape velocity, it's just unlikely for a particular particle to, for a particle to, it is fairly likely. |
