hi, i was wondering, for a blackhole, as everyone knows,the escape velocity is greater than light. this means that the information about the existence of the blackhole in terms of light never reaches the observer. so if the blackhole were the cease to exist at an instant of time, the observer will never see the event happening. He will only feel the instantaneous change in the gravitational field. so in a way both gravity and information has traveled faster than light. an alternative way of considering the same problem would be by expressing gravitational force to be transferred by gravitons. in this case the gravitons reach the observer but the photons don't. so gravitons can escape the gravitational field or 'climb over' the curvature of space time while photons cannot. so gravitons can be considered to travel faster than the escape velocity giving the same consequences as the first case. where is my thought process incorrect?
