Can gravitational attraction (generated by a super-massive black hole, for instance) accelerate you faster than c?

Terdbergler said:That it's impossible to go faster than light is common knowledge. It should be obvious that I'm asking for more information than just that. Does the body reach a terminal velocity in a vacuum? Or will the acceleration itself "decelerate" but never stop? There are a number of ways this could hypothetically play out. I'm asking for the way in which it would actually play out.
Mordred said:Infalling matter disintegrates into energy and becomes part of the accretion disk.
Drakkith said:This is actually a little more complicated than you realize. You are talking about incorporating an accelerating object with increasing gravitational time dilation. An observer stationary with respect to the black hole would need to compensate for the time dilation in order to properly calculate the acceleration of the infalling object. I honestly don't know exactly what the observer would "see", so I can't answer your question.
I don't think this is very accurate. Infalling matter is heated up within the accretion disk, which does emit radiation, but I wouldn't say it "disintegrates into energy". Matter can and does fall past the event horizon intact.
Mordred said:the disintegrates into energy is the terms used in the article, " the disintegration process must convert most of the rest mass energy of the infalling particle to kinetic energy, in the sense that, in the center-of-mass frame, the E particle must have velocity v > c/2. Its under the section described as the Penrose process. Essentially the energy of the particle splits into two particles one positive, and one negative, the negative particle falls in the positive particle escapes to infinity. page 44
Superluminal gravitational acceleration refers to a hypothetical phenomenon in which an object is accelerated faster than the speed of light due to the influence of gravity.
Currently, there is no evidence or scientific theory to support the possibility of superluminal gravitational acceleration. According to Einstein's theory of relativity, nothing can travel faster than the speed of light, including gravitational effects.
Regular gravitational acceleration occurs when an object is pulled towards a massive body, such as the Earth, due to the force of gravity. Superluminal gravitational acceleration, on the other hand, suggests that an object can be accelerated to speeds faster than light due to the influence of gravity.
If superluminal gravitational acceleration were possible, it would challenge our current understanding of physics and the laws of the universe. It could also have significant implications for space travel and the exploration of distant galaxies.
Currently, there are no known experiments or studies being conducted on superluminal gravitational acceleration. However, scientists continue to explore and research potential theories and phenomena that could potentially challenge our current understanding of the universe.
