While contemplating a meaning of Einstein's e=mc²
--

I question: Why would a photon move @ the speed of light?

Light has both wave and particle properties, when scrutinized.  It implies characteristics of spin are involved.

Photons are the most primitive known particle.

I postulate “photons move @ speed of light, when two polar orientations incorporate spin @ speed of light.”

Electric 1 pole + 1 spin and magnetic 1 pole + 1 spin properties that relate in some form of perpendicular agreement.

A deep thought, since… it also implies (to me) photons that don’t spin at the speed of light, constitute space.

I don't know what this means.

Trying to condense this theory to the narrowest of terms.   

I believe electric and magnetic properties also relate to spin.

If you spin a marble, like a top, there's a pole perpendicular to the floor if it remains in one place, directly over a South pole located on the bottom.  This I think of as the first spin (possibly/probably) akin to magnetic pole.

Roll the marble on the floor and will have a pole that exists parallel to the floor (akin to electric pole).

If the marble was a photon, it would need both spins @ speed of light to achieve light-speed in a relative straight trajectory.

When light is circularly polarized, it carries spin.
This mechanism was recently used to spin up microscopic spheres to millions of RPM (revolutions per minute) by illuminating them with a circularly-polarized laser.

Photons are not the most primitive particle known, they are packets of energy.

As for why

They travel at the speed of light as they are massless, they travel at the speed they do because it is the maxumum speed permissable in space time without disintergration, when things travel faster they are in the process of disintegration. if light travelled faster it would disintegrate to more electromagnetic radiation than existed initially.

when things travel faster...

They don't.
