Jul 20, 2011 at 1:19 comment added user4552 @Zassounotsukushi, you've phrased this in terms of QM, but the answer is really classical. Say we have a thoroughly classical object like a rock. In its own rest frame, it has some mass-energy density. Transform into another frame, and its mass-energy goes up by a factor of gamma, while its volume goes down by gamma, increasing its density of mass-energy by gamma^2. But this doesn't make it a black hole. The definition of a black hole can be stated in language that is independent of the frame of reference, so an object that isn't a b.h. in one frame can't be a b.h. in another.
Jul 19, 2011 at 16:33 comment added Alan Rominger I am tempted to infer from your answer that with sufficient energy the wave function for a particle could become compact enough to become a black hole. I imagine this is wrong, but I would like a sense of why.
