    there's that Hawking theory called Hawk's light or whatever, but it's still up in the air. 'uh... the gravity moves so fast it moves faster than light so it sucks up light too." yeah, not buying it.

    oh, it's called hawking radiation.

    but it makes no sense, gravity does not effect light, only what's percieved as light. A black hole is litteraly suck it up like a kid drinking koolaid.

    Ah, lazy has a masters in quantum physics now eh?

    And actually, gravity DOES affect light, and this has been directly observed many times. This is not in dispute. Light travels in a "straight" path in euclidian space, but it is clear that our space is not based on euclidian geometry, but rather more akin to relativistic space. It "bends" as we percieve it. Light travelling near a strong gravity well will change course. It will not change speed as light's speed is an absolute in all frames of reference. As such, when a star passes behind the sun, it will appear to "hop" a bit because the light has been distorted by gravitational lensing. In fact, gravitational lensing can create magnified images of distant galaxies, or even "split" the same galaxy's light into what appears to be 4 galaxies of the exact same type.

    In fact, gravitational lensing is currently being used to detect planets in distant star systems. When a planet passes in front of a star, it can briefly focus a burst of light towards us, which we can now detect.

    So yes lazy, gravity DOES affect light. Do some research next time.

    But moving along, the idea behind a black hole is that it does not "exterminate" everything. It compresses it into a single point that is zero size and infinitely dense. That is not to say it is infinitely massive. Only it's density is infinite.
