I Thank your efforts to explain something really difficult to understand, Johnny.

Then really the photon cant stop to moving ?

Are you saying that photon cant stop ? when you says that

"A photon can never be at rest within any inertial reference frame."

Then my finally question is: the massless photon dont contradict the Einstein's E=mc2 , because E=mc2 is equal 0 if m=0 ?
