Is movement a transformation of one energy into another?
Only when noninertial effects (accelleration) is involved. On the other hand, how to detect free motion inertially?
Does that mean that we could one day evolve to see ultraviolet, X-rays, etc?
There's no reason for it. We are composed of carbon molecules and our energy density scale which we can perceive in form of light is well adopted to binding energy of these molecules.
Why do photons at shorter wavelengths have more energy than photons at longer wavelengths?
As a periodic waves they contain more acceleration/deceleration events per unit of space-time.
When a form of energy transforms into another form of energy, what exactly is transforming?
In Aether Wave Theory all energy transformations are basically the evaporation and/or condensation of aether particles. For example, when object falls into gravity field of massive object, it gains kinetic energy onto account of kinetic energy, and it basically dissolves in dense vacuum surounding this massive object, we could say, it evaporates into techyons, i.e. travels through time dimension into future.
