... the v and you change E. So assuming that you have the same E for all v is ridiculous. “ Mass** ” goes to infinity as v approaches c: “ Mass = Energy * c^-2 * ( 1 - v^2 / c^2 )^-.5 ”. ** i.e. “ Relativistic Mass ”, not “ Invariant Mass ”, not “ Intrinsic Mass ”, not “ Proper Mass ”. Relativistic mass is obsolete. We no longer teach it. -- // The TimeLord says: // Pogo 2.0 = We have met the aliens, and they are us!

...someone like Sanny, who knows little English or physics, isn't it enough to just say: “ Mass = Energy / c^2 ” ? No, since that is only true if v=0. Otherwise in an inertial reference frame, m = E / c^2 * sqrt(1-v^2/c^2) So for fixed energy, the mass goes to zero as speed approaches the speed of light. [smile] (Just kidding on that last statement.) -- // The TimeLord says: // Pogo 2.0 = We have met the aliens, and they are us!

... always conserved? See http://www.geocities.com/physics_world/sr/conservation_of_mass.htm Good work there. Since all the steps can be reversed, given equations 2a and 2b, that URL actually shows that conservation of momentum is equivalent to conservation of mass (providing there is no matter-energy conversion, as in matter-antimatter annhiliation). -- // The TimeLord says: // Pogo 2.0 = We have met the aliens, and they are us!

... into pieces. Not that anyone knows of. Besides, it's unlikely since an electron is a lepton. [...] Once Scientist learn how to break electron into pieces and see how those pieces of electron react Science will develop a lot. It would change the standard model for sure because then we would know that leptons are not fundamental particles. -- // The TimeLord says: // Pogo 2.0 = We have met the aliens, and they are us!
