Loren,
I am impressed that you ask for constructive criticism of your ideas. I don't doubt that there are experts here who can read your website and pass some constructive criticism along to you.
I looked at your cubic equation slope derivation enough to satisfy myself that it is probably correct. (I didn't fine-tooth-comb it enough to be certain, but the steps you took looked plausible.) I find it impressive that you knew differential calculus well enough at age 16 to do that.
I am no expert (on anything), but I will make a few comments on the fine structure constant part of your website. You say that it is "the relative strength of the electromagnetic vs the strong force." I suppose that it is fair to say that, to the extent that the coupling constant for strong nuclear interactions between nucleons by pions is approximately equal to one. But it seems like your statement that I have quoted is a little misleading, in that alpha is a dimensionless number that could be calculated from quantum electrodynamics alone, without any reference whatsoever to the quantum theory of the strong nuclear force. If the latter had been found to have a coupling constant for nucleon strong interactions of, say, 0.1, (as, a priori, it could have) you probably would not claim that it is "the relative strength of the electromagnetic vs the strong force." No huge deal, just nitpicking a little.
But from a modern point of view, the strong interactions between nucleons are considered to be a complicated, downright messy phenomenon, involving baryons and mesons which are themselves composites of more elementary particles. The quark interactions mediated by gluons are considered more fundamental. I am not sure what the dimensionless coupling constant is for quark-quark chromodynamic interactions, but I would guess it may well not be all that close to 1.
Aside from all considerations of strong or chromodynamic forces, isn't the modern viewpoint that the coupling constant in quantum electrodynamics is an "effective" or "running" constant, in the sense that it has a value that depends on details of the measurement? In particular, the value of it that you quote on your website pertains to an elementary electric charge that is screened by vacuum polarization and seen from an infinite distance. The coupling "constant" goes up in value when measured at ever smaller distances where screening is incomplete, right? So in view of that, can you realistically expect that alpha is really all that fundamental of a number, and that it has ties to the size of the universe? (I am not trying to say that it couldn't, I am just questioning what motivates you to believe that it does.)
