>The principle in classical mechanics that E ? mv2 was first developed by Gottfried Leibniz and Johann Bernoulli, who described kinetic energy as the living force, vis viva. Willem 's Gravesande of the Netherlands provided experimental evidence of this relationship.

e=mc^2 is the biggest poison in science community
einstein just twisted good old kinetic energy equation using his askhenazi jew schizo brain to ruin physics forever

"c" is not constant but it's the velocity of moving object, thus photon energy IS the velocity of photon

once you assume photon energy IS velocity everything falls in place

v = ~3 million m/s with large deviations based on photon energy
m = mass of photon

thus
e=mv^2
is just kinetic energy equation from 100 years before einstein was even born, there is no magic matter/energy transformation

prove me wrong
