RacingGun said:Sorry, that's just wrong... you can create matter from energy, this is what particle accelerators and "atom smashing" is all about. There is no conservation of mass, only conservation of energy... Einstein anyone?
Take 2 particles... make them go REALLY fast (ie, something relatively close to the speed of light), smashy them together, and you can get a 3rd particle that is heavier than the original 2 combined.
Well spotted that man! I love it when someone is shown to be wrong. Excellent!
