Does gravity vary with velocity?

  1. May 26, 2010 #1
    Einstein calculated that the bending of light around a body is twice the value that Newton calculated. My impression is that this is due to the curvature of space which is velocity dependent.

    Does this mean that a projectile passing the sun at close to the speed of light would be measured as being gravitationally accelerated at almost twice the value that Newtonian gravity would predict?

    Put another way, would it also mean that a slow moving body would experience a weaker gravity than a fast moving body?

    Thanks, the abstract of the paper did answer my question. I'm also amazed that you were able to relate my question to that paper.

    It is not required but it would have been nice to have browsed the whole paper.

    Thanks
