| ``Re: E = m c ^2 ?''

| Brenton,
Great question!
E = mc^2 is not the whole picture, just the rest energy which holds if the particle's velocity is significantly smaller than the speed of light v << c, the Total relativistic energy is
E=mc^2/sqrt(1 - v^2/c^2)
if you look at the kinetic energy
K = mc^2/sqrt(1 - v^2/c^2) - mc^2
you see that as v -> c, K -> infinity so you won't go faster than speed of light
since, forums don't do latex, start of an entry here
