: : It is just a thought exercise. As a practical matter, : it may not be possible to propel a large chunk of : matter (i.e. a space ship) to anything approaching : relativistic velocities (given current technology). : The question is though, does relativistic mass have the same : gravitational effect as rest mass?

: : Well, i would find it hard to believe that ships traveling at that rate would be able to. the mass of the object would be to great to actually to at that rate...come on..THINK ABOUT IT! : : Gaby

There is no such thing as mass "at rest", only at rest relative to some other matter.

Here is a kinda neet thought exercise... You could make a spaceship travel at the speed of light reletive to a much smaller object coming towards it, such as an atom in a particle excelarator. Relative to the particle the space ship could reach the speed of light.
