Wouldn't it be true to say that as E=mc(sqared) that a high engergy partical also has high mass simply because if we revert to the therory of imcertainty (i think its called that) in which the errors to which we record everything reach such a large value that they are infact exceptionally larger that the value recorded this tends to only affect things on a quantum level. This would mean that a high enegy partical could change energy from energy to mass and back to energy over a minute period of time making seem as though both are present simultaneously. This would cause the wave properties of the fundamental particles (ie electron, positron, tau, quark etc.) would be constently changing wavelenth and would caonstitute the colour change property of many particles. I do beleive however that a quark in not fundamental. I plan to prove my theories in the future. I hope to (but secretly know i won't) be bigger that Einstien.
