Re: Don't forget relativistic effects
But if we are dealing with gravitational attraction, this INCREASES the pull on the object in direct balance with its increase in relativistic mass, so the acceleration remains constant. However, because of the Lorentz contraction of space and time, c is never violated.
Also, gravity is a relatively short-range force compared to distances acheived at a close asymptote to c, so unless the attractor is literally infinite in mass, the velocity will never get really close to c
