It is sad that pitiful Potter doesn't understand the physical

significance of the equation:

E^2 = (mc^2)^2 + (pc)^2

Perhaps a one minute physics video will help Potter sort

things out.

Perhaps Potter recalls that a photon's Momentum is

p = h?/c = h/?

and Photon Energy

E = h?

Yet in the first equation, Potter is pointing out

that if mass is zero, then

p = c/E

Let Potter cogitate on what he sees as a discrepancy.
