THe beef I have with the theory of relativity is that first of all they say anything with mass cannot achieve the speed of light or greater! Which doesn't make any sence since if you take the momentum p=hv. And equate it to m(v) you could actually find the frequency of particles if that is true then working backwards you should be able to find the mass of photons of certain wavelength. when you do this you actually find some mass. Maybe I am missing some thing.

THe other thing is why can't nothing go past the speed of light? could someone explain this to me?
