"At light speed"
They say that, nobody can go faster than the speed of light, somewhere around 186,000 per second.
As you get closer to the speed of light, the mass of the object then becomes greater and, does so exponentially as does the energy needed to continue out.
Perhaps, the photonics structure exploits some of the fundamental laws.
Perhaps like a warp drive the photons actually creates a vacuum within itself that propels it, the same one responsible for the non decaying spin of an electron.
Frequency would then, only play a roll in the photonics structure themselves,
giving us our visible light spectrum.
Now just imagine how the world would look if we could see more than just visible light,
how would that change our perspective. . . or would it change at all. ?
