I hereby issue a challenge to all you gents who keep telling me
how dumb I am --- let's see you solve this problem (as I have).

First, we use as the mass of the photon, Einstein's version: m = L/c^2
(If you insist the photon has no mass, you are hereby excused --- go
somewhere else.)

Einstein did not say that the photon has mass. He said that if a
massive body gives off light energy in the amount L, then the mass of
the body decreases by an amount L/c^2.

You are assuming that mass is conserved and that the mass has to go
someplace and that therefore it must go into the photon.

VERGON

Exactly so. If it doesn't go there, where does it go? Or do you believe
mass can be destroyed?

This is simply an incorrect assumption. Einstein didn't make it,
either. Mass is not an additive property of a system. That is, the mass
of a system is not the sum of the masses of its parts. It simply isn't,
experimentally, and no insisting that it damn well *should* be will
make it so.

VERGON

Again your wrong. In so called experiments where mass seems to be
missing, you'll find that the mass balances if you take into account
that radiation has mass AND BINDING FORCES have mass.

Are you aware that Einstein declared mass and energy are conserved as
one law?

Goood try, but no cigar :-)

Show me a process or experiment where mass is missing.
