The http://en.wikipedia.org/wiki/Dirac_equation" , which itself is based upon the relativistic energy-momentum relation [tex]E^2 = p^2 + m^2[/tex] (natural units). And here comes my question then:
Why do we throw away the negative energy solutions in relativity but do we keep them when we combine it with quantum theory. Clearly this must have got something to do with the quantum part, but with what?
Thanks, Hendrik
