BP:

I'm no physicist, but from what I've been able to read that summarizes the work of Planck and a few others, I don't think theres much difference between philosophy and high-end physics.

Pappy:

Nice proofs. Are you aware of any data collected so far that disconfirm Einstein's relativity ideas?

As to E=Mc2:

It's a "simple" derivation of F=Ma wherein:

Energy is the ultimate expression of force;

Mass is our constant for substance;

and the speed of light squared is just the use of an assumed maximum constant speed (the square of which is its accelaration).

If you characterize lightspeed as the fastest possible speed, it must be constant in a formula for all energy, the rest is Newton redux.
