: : : : 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.

Yes, what would happen to the spaceship from the perspective of particle? Would the spaceship appear so massive as to seal itself off from observation by the particle by forming an apparent event horizon?
