What is the flaw with e-mc2?
If E is the rest energy and m is the invariant mass, the equation is correct. If E is the energy of a massless “particle,” such as a photon, the equation is incorrect. For all other meanings for E and m the equation is either wrong or is an approximation for low speed objects.Jan 21, 2018
