Re: is there a "theoretical" mass for a photon ???

"They" is wrong. It has been shown that a photon has mass, yet "they"
refuse to believe it and so "they" continue to deny that fact ("They"
being Hobbitt & Roberts, et al, who also believe space-time exists as a
place somewhere in some galaxy far far away and not just in our minds
as a math construct).

But do we know the amount of energy a single photon can produce and
then use E=mc^2 thus m = E/c^2 (or another similar equation) ?

I don't think we can say a photon "produces" any energy. E=mc^2
implies an interdependency between mass and energy as does the
Principle of the Conservation of Mass and Energy. Thus, one does not
produce the other, rather, where one exists, so does the other. The
Hobbits et al at times admit a photon has mass, but when they do they
also claim that the mass is so small it is of no consequence. How's
that for the scientific method, eh? Put an empirical fact against a
fantasy and deny the fact just because the fantasy fits current (but
fallacious) science trends.

"They" claim that momentum can have energy without mass, but they
cannot refute E=mc^2, which asserts we cannot have mass sans energy,
and vice-versa, nor can they explain how we can have momentum without
mass. There is more than just a psychological basis for their denials,
however. They also claim that photons travel along with em waves, even
while admitting that matter cannot travel at c. If the photon was not
massless, they could not then explain how matter, having mass, can move
at the speed of light. So they invented a math construct claiming to
show that a photon can have momentum even if it has no mass.

E=mc^2 simply states that the amount of energy in a mass is equal to
its mass times the speed of light squared. m=E/c^2 would simply state
that the amount of mass in a given energy is equal to the given energy
divided by the speed of light squared. The former formula provides for
a huge amount of energy for a very small amount of mass, so the latter
formula naturally provides for a tiny amount of mass for a very large
amount of energy, as we should expect. Compare what I write here with
what I have written about how photons do not move along with light
waves, and see how they fit together in a most logical way.
