Meet the Supermassive Black Hole experts - BBC science

Meet the experts of possibly the scariest phenomenon in the universe - super massive black holes. Described as gravity gone mad, whole solar systems can be sucked into these terrifying masses. Learn more with this fascinating BBC science show 'Supermassive Black Hole'.

I want to throw Justin Bieber in it ;D

the music from predator yo!!!!!! :P

@albinoman13bt my understanding is that the actual black hole object (which cant be seen as it is past the event horizon) may in reality actually have finite dimensions and a finite density (being the core of a massive star after death), but gravity is just so great that it could theoretically be given infinite density and therefore be thought of as a singularity. but all we can do is speculate on these things. black holes are fascinating!

[albinoman13bt]

@mattsbo Maybe the event horizon is the size of a the solar system. I was referring to the singularity at the center. From the Wikipedia article for "Black Hole" under Singularity: "For a non-rotating black hole this region takes the shape of a single point and for a rotating black hole it is smeared out to form a ring singularity lying in the plane of rotation. In both cases the singular region has zero volume...The singular region can thus be thought of as having infinite density."

@albinoman13bt not really, its an object, could be the size of a marble or a planet, it just consists of an incredibly dense matter that creates a gravitational field which has an acceleration higher than that of the speed of light (about 300,000 km/s/s). the event horizon (point above the surface of the object at which no light can escape its gravity) is much larger than the object however. it is not a 1 dimensional point in space, but rather an extremely dense object of matter

[albinoman13bt]

I hate it when she says "it could fill a solar system". No it couldnt. Black holes are a 1 dimensional point in space. It's a hole you can fall into from any direction. It's why relativity can only work really close to a black hole, but not for it the black hole itself.

It's because those damn people divide by ZERO.

GALACTUS?!!!

[joshybang1]

ohh ive just scared my self now #

just imagine your just walking then booooooooooomm

you fell int a black hole foooooooooooorrrrrr evvvvvvvvvvvverrrrrrr

you will never come out until infinitum years :( im scared :(

[joshybang1]

hey look a roundabout lets go on

weeeeeeeeeeeeeeeeeeeeeeeeeeee

wait oohhhhh craaaaaaaaaaaap ahhhhhhhhhhhhhhhh

then there gone 4eva the end :D

I wish osam would trip into thi!

I wish justin bieber would die in hell with all his friends!
