If relativity predicts mass increases with velocity and length decreases in the direction of motion, if you moved an object to a high enough velocity would its density reached a point at which it would collapse upon itself and become a black hole?

A person observing it fly by might think so, unless he thought the relative motion was due to his flying in the opposite direction. In either case, a person moving at the same velocity as the mass would see it at rest and could find no increase in density.

Relativity has many strange effects, but the effects of relative motion can be among the most difficult to understand. Good luck!

Best, Dick...
