Can relativistic mass create a black hole?
Suppose we have two neutral particles moving parallel to each other, and we accelerate them to close to light-speed. Does the gravitational attraction between them increase? Does anyone know? What does theory say? (Not sure how to accelerate neutral particles — I only specified that to avoid complications of electromagnetic attraction/repulsion.)
What do you mean by 'relativistic mass'? I guess any kind of mass could create a black hole if there was enough of it.
Moving 0.99999999999c like in e=mc2
@OleBlueEyes Well you'd need an awful lot of it.
