I was wondering, after a chemistry class..
my teacher said that a photon has energy but doesn't have mass.. But according to Einstein's theory E=mc^2, if m= 0 then m*c^2 = 0, so a photon doesn't have energy..
also the teacher said that gamma rays travels faster than light, which sound completely ridiculous to me because gamma rays are EMR which are the same as light...
Thanks in advance
