[QUOTE="bolen, post: 2270736, member: 1442"] No sorry a black hole is only formed if the REST mass of the object is greater then a value (which is 2 GM/c^2 for a non rotating non charged BH) You are correct, measured by an observer in a different frame, your mass would increase and if you could accelerate up to c the observer on the ground would say it is approaching infinity. (lets stick to constant velocity from now on, it's easier) But if you measure your mass in a ship going at .999 c you say your mass is the same. However to the guy on the ground says your mass is now M/Sqrt[1 -(.999)^2]= 22.4 M So he says your mass is 22.4 times your original mass. I say you increase energy not mass, I (and most relativists) resevere the term mass for REST MASS. Hope that helps [/QUOTE]
