Default mass is light.

tomcat,
More importantly, it's interesting to note that we're seeing no actual
hard numbers coming from these wizards that usually claim to know all
there is to know.

I believe there's at least 1e100 photons per atom, and we're talking
about all the way from those extremely low frequency gravity photons of
infinite light years to those sub gamma photons of the sub-picometer
status, thus we have lots to pick from.

Light is certainly one of the strangest of objects. In the Double Slit
Experiment it acts like a wave until you look for the particles. Then
it becomes particles, instead. Albert Einstein used the speed of light
as the upper bound for all possible speeds in the Universe.

In the broad sense light includes visible light and invisible light,
such as X-Rays and Gamma Rays, besides. This is why solar cells
produce as well on cloudy days as they do on bright sunny days. Solar
cells react to the UV and shorter wavelengths and they can punch
through clouds.

In fact, this is how you entangle photons. One method is to take a UV
photon and turn it into two Infra-Red photons which equal the original
energy of the UV photon.

Recently light was speeded up in a doped optic fiber. Since the light
exceeded the speed of light in a vacuum it transversed the optic fiber
backward, instead of entering where it entered. In other words you
pour the light in end A and it immediately comes at you from end B.
Reference: University of Rochester in New York. This is creating
speculation that exceeding the speed of light can take you backwards in
time.

So, light is a little weird. Perhaps that is why there is some action
on this "mass is light" topic. It is time to air some of the weirdness
of simple photonic . . . light.
