So, now I look at a peculiar situation with light photon motion and growth.. Can anyone comment on this thought? Assume frequency is VERY important. Then, E=Mc^2 might imply E- M A'cf where (a) A' is meters squared per sec, i.e., m^2/t (lower case m is meters!) and (b) f is frequency, i.e., 1/t (c) c is light velocity, m/sec such that c^2 is identical in units to A'cf, i.e. (m^2/sec)(1/sec)(m/sec) =(m^2/sec^2) So the ubiquity of photon-electron transitions lie in A' and f! If A'f = c, then c^2 implies A'f =c. But if not, strange things come out of this..
