text: would'nt the velocity of light change near a black hole? if so ,what would be the velocity of light? see the gravitational pull is very large and the light is absorbed in it.so we can say that the speed is zero.but nobody has done this type of thing before. we are sure to say that the direction is sure to change.the black hole was spotted in cyguns constellation,by the change in the rotation path of a "star".so you can see the gravitational pull of the same.
