Exist velocity greater than or equal to the speed of light

The main idea is due to image black holes "feed back".

>>> See the black hole swallowing a star

As we know, the black hole's gravity is extremely large. The speed of rotation it was possible to bend the path of light (see picture black hole "eating back"), this proves its rotation speed can equal the speed of light.

And with its gravitational force it into the star attraction. When the star was a black hole "swallowing" absolutely did not see a ray of light emitted, this proves the "seed" light is the black hole's gravitational attraction and retention in other words: the velocity smaller than the speed of light attraction of black holes.
