Well yeah, IF you could get near the black hole, and out again, which is practically impossible. A lot easier is to take a rocket, and try to get as near to the speed of light as you can. Time will slow down, and when you get back to earth, a lot of time will have passed :).
it IS Impossible.
You would become disintegrated (sp?) in milliseconds.
No human body could withstand the gravitational force of a blackhole.
Black holes without a doubt exist. The picture in teh avatar is based on fact. The light beam athe center shooting out is a form of raditation but I dont remember what kind.
The best description Ihave seen of a black hole is to imagine a rubber sheet that cannot rip. A bowling ball would be the sun and a baseball a planet. The baseball spins on the lip of the gravity well of the star. any closer and we start spiraling in, any farther and we spiral off into space.
When a sun dies it does one of two things it expands into a red or blue gas giant and then collapses into a neutron star. Imagine the size and weight of 80,00 earths packed into a density the size of a golfball. Tiny and hard to detect but it still exerts gravitational force. The gravity well i smaller but much stronger so if you were to pass too close you would get sucked in and crash on the surface and be crushed by the gravity.
If the star has sufficent mass, it collapses so fast that it implodes into a infinitely deep hole in the rubber sheet and anything near it gets sucked in.
You cannot survive entering a black hole. Once you enter beyond the event horizon you are screwed. When you go down the hole you experience "spaghettification". Your body is instantly at both ends of the black hole as your molecular structure is ripped to pieces. I doubt if you would ave time to realize what happened.
This might help.

ive heard they last a couple of seconds then die out.
Depends on the mass. Some hvae lasted billions of years. In fact tehre is evidence to support that there is a black hole at the center of galazies. One has been detected at the center of our own Mily Way using the Chandra X-ray observatory.
So... the speed of light is a constant, right. Well when light gets sucked into a black hole it would still be moving at the speed of light, but in the blackhole time moves slower so if light was still moving at the same speed but time was moving slower...then wouldnt light be moving faster?

Actually no. The generally accepted speed of light is simply the speed of light in a vacuum, when passing through a substance the speed of light varies. In water for example, light travels at about three-fourths its vacuum speed. We can even move stuff faster than the speed of light :) which bodes well for space travel

I think you're confused, the speed of light is given with a time unit accompanying it, as are most speed values. Without a unit of time speed values become meaningless.

Oh yeah incase any of you like reading up on the science behind going faster than light in a vacuum: http://www.washingtonpost.com/ac2/wp-dyn?pagename=article&contentId=A9431-2000Jul19¬Found=true
In a landmark experiment, scientists have broken the cosmic speed limit, causing a light pulse to travel at many times the speed of light--so fast that the peak of the pulse exited a specially prepared test chamber before it even finished entering it. That seems to contradict not only common sense, but also a bedrock principle of Albert Einstein's theory of relativity, which sets the speed of light in a vacuum, about 186,000 miles per second, as the fastest that anything can go.
the picture in Excessions sig may not be real but it is based off the knowledge of accretion discs, these are one major way of spotting black holes and there are with these quite often the pillars emitting from either side of the disc of i believe some radiation or it may be excess plasma.
not an actual accretion disc tho.
an actual accretion disc.
The biggest star couldn't survive a black hole. Anyway what's a WHITE hole i heard somone mention?
