Conservation of Momentum. Certain of it now.

I am almost certain that there is no energy to do any kind of mechanical work without momentum and I am talking about the subatomic level to the largest cosmic structures. Some of the first electrical experiments were with fur pelts rubbing glass rods to yield a static electric shock. The largest electronic generators require momentum to allow what is essentially friction that slows down the wheel to yield work energy.  the conservation of energy rule is all about requiring resistance/ interference with a magnetic charge or even the creation of a magnetic charge because of the properties of momentum involved. It is all very reflexive in nature.  the net out put of an electric current at the end of any work done with it in all kinds of electrical devices or just in carrying the charge over long wire distances is the output of infrared photons mostly. The photons then are immediately related to the grinding resistance to momentum of the generator that starts the process.  Therefore it all comes down to what I would call conservation of momentum.  I am talking about common denominators of photons then as code for releasing the internal energy of residual momentum.  If you wanted to believe in the big bang theory or a small bang theory among other bangs in the universe than then  momentum is the intergalactic currency and possibly a better metric than the speed of light.

All energy in the universe is derived from Momentum (?) Maybe a great bet.

Hard to believe for the uninitiated but all of the energy in the universe is probably derived from momentum. That is just mass with velocity . If that is entire reservoir of energy the metric to measure it is relatively complicated and has no relationship to the speed of light constant unless used to measure distances between momentum cells if close enough to reflect light
