light^2

from here
http://en.wikipedia.org/wiki/Event_horizon



is this a region where the gravitational attraction is equal to the speed of light?

meaning that as something falls into an event horizon of a black hole, it must be accelerated to the speed of light otherwise it would not be a black hole.

as stated above, if an object is approaching a relativistic velocity (meaning reaching the speed of light), then by if you follow special relativity dogma, that object must be turned into energy as it approaches and becomes equal to the speed of light.



Please, anybody tell me where I am lost in this reasoning.
