Can C be measured in MeV?? If so is this per photon? Basically as the title states, can you measure C in MeV, i read ALICE was nearing Acceleration of C at 14 MeV (These numbers are what i can remember from a while ago). Then is that measure of 14 MeV for say a single atom, or does it apply for larger objects (More mass needs more energy to move it so i think not but i may as well ask)? Oh wait, nothing can move at C can it because it hass mass. Im starting to think, bad things usually ensue. Any help would be great folks.
