My question is threefold, the second is based on the premise that the first is true, and the third is based on the other two. 1. As relative velocity increases, mass also increases, correct? In this case, could you accelerate away from an object to a velocity fast enough to make its schwartzchild radius larger than the object, creating a black hole? 2. Would this object then collapse in upon itself so that if you slowed down to zero speed relative to the object, it would still be a black hole? 3. Will the outward acceleration of the universe ultimately result in the formation of black holes due to the very high velocity of objects relative to one another? EDIT: one factor I did not account for, in retrospect, is the deformation of an object at high speeds-- I read a little bit about this, but I don't know exactly where to go with it. Black holes have no hair, right?
