Say light can be sucked by black holes then there must be a force to do so. Since there is a force acting to the light, then the light must be accelerating. So the speed of light plus the extra velocity gained by accelerating = faster than speed of light.

no?

Are you suggesting the idea that since "mass increases" as you approach the speed of light, then objects will turn into black holes before they can reach the speed of light? If so this is a misconception, see this entry from the Usenet Physics FAQ along with pervect's post #9 on this thread.I know Einstein said it is impossible to travel faster than speed of light as the mass would get infinitely large. But if black holes exist and even a beam of light would be pulled back by gravity.

The second law is a microcosm of SR. As v [itex]\Rightarrow[/itex] c, a gets asymptotically smaller to zero and is at "just before" zero "just before" v = c so an object is never "bumped up" to the speed of light.
