If we look at infinite wavelength energy, this is a misnomer. The product of the frequency and wavelength needs to result in C, which can not happen with the product of infinite wavelength and zero frequency. So if we began the universe with this, we would be beginning the universe without mass or energy. There is still something there, but it is technically neither mass or energy. We will make the energy out of this.
One possible way is to blue shift it until the wavelength-frequency product becomes C again. This would require sort of a contraction of space-time. I will get back to this.
If these quanta, of not-energy, are moving at C, all will see the same thing in their C reference. Infinite space and time would appear to overlap, so they all appear to overlap. But in a zero reference, they will appear distinct and spread out to occupy infinite space for all time. To get the needed contraction of the zero reference, for the blue shift, the potential or ambiguity between these two extreme references need to equilibrate. This requires at least some of the C reference fall from C for the blue shift of the O-reference. The C- aspect, will see itself as a point inside a bigger sphere of not-energy. The 0+-reference, will sees things gaining this endothermic blue shift potential.
The aspect lowering from C to C-, is neither not-energy or energy since it is in a reference that is less than C. It is the onset of mass. While the contracting and blue shifting reference is starting to gain the characteristics of energy. One way to do this, without the top end dropping below C, is with a medium affect that makes the speed of light only appear to slow from C. What this implies is cause and affect appearing to reverse, with the blue shift providing the medium that allows the apparent below C, that makes the medium possible, so that it can fall below C to generate the mass.
This can be accomplished with a siphon effect in space-time. The final goal is convert not-energy into mass-energy. Like the siphon, we first need to pull the not-energy up the siphon hill, so its gains potential. The siphon, is recycling some of its output potential up front, for the siphon hill, to create the medium by which C will not initially be violated, but appear to slow, until it gets over the hump, and then it can drop below C and form mass as it flows out the bottom of the siphon.
