So says a 20th century person. In this 21st century, though, a mass
IS a quantity of matterm, whether or not it has any weight.

A photon is a quantity of energy with a material vehicle as agent.
Of itself, it has zero weight, whether alone or flying "back to back"
with another such quantity.

Light's flow is weightless. In this sense it always falls under
gravity but it doesn't go below light speed unless its in a matterial
medium.

Exactly.

Aether and matter are different states of the same material.

'DOES THE INERTIA OF A BODY DEPEND UPON ITS ENERGY-CONTENT? By A.
EINSTEIN'
http://www.fourmilab.ch/etexts/einstein/E_mc2/e_mc2.pdf

"If a body gives off the energy L in the form of radiation, its mass
diminishes by L/c2."

The mass of the body does diminish, but the matter which no longer
exists as part of the body has not vanished. It still exists, as
aether. As the matter transitions to aether it expands in three
dimensions. The effect this transition has on the surrounding aether
and matter is energy.

In E=mc^2, mass is conserved.

There are two kinds of energy. One is point the other is spread out.
This is matter's mass and light's spread out waving or frequency.

Mass is not a primal property. Mass is inertia, period! By the so-
called 'strong equivalence principle', weight... THAT! is the only
actual physical observable of what is called mass. This is where the
idea of 'rest mass' comes from. If you can't weigh it, or accelerate
it, mass has no meaning. But, energy appears to be 'massive' in so
far as it the equation 'kmv^2' seems to hold and... Einstein elevated
it to an equivalence 'principle'.

I have come to the realization that mass is an electromagnetic
phenomena. That is to say, the fields that constitutes 'matter' will
create counter EMF effects when perturbed from equilibrium. That EMF
is the source of inertia, thus, by definition, 'mass'.
