The speculation which follows could only be confirmed or refuted by studying the products of hydrogen fusion. Hydrogen exhibits a specific absorption and emission spectrum (only certain wavelengths of electromagnetic energy is acceptable. We must assume that these are the allowable energy states. It is also obvious that the product of the fusion of two hydrogen atoms is not helium, but rather some as yet unknown atoms must result, since it would turn out that those unknown atoms, which were the first products of fusion, were also the 'allowable energy state' (with a net loss of radiated energy being the excess). Therefore we can wonder whether or not a relationship exists between these two types of alllowable states.
The image above shows the emission lines of hydrogen as a function of the wavelength of light (longer, redder wavelengths to the left with the shorter wavelengths to the right). These emission lines are arranged in ‘series’ and they converge to a point, which is the end of a series. According to my speculative hypothesis, a relationship exists between these emission lines and the products of hydrogen fusion (the fusing together of two hydrogen atoms to create a new atom). You cannot create Helium by fusing together two hydrogen atoms (that would require at least four hydrogen atoms, with a little bit of energy left over). We know that stars are massive net losers of energy, and that therefore fusion of two atoms to create a new atom is not an efficient process. Therefore I am assuming that the fusion of hydrogen into helium occurs in a number of steps, and that the fusion of one kilogram of hydrogen into helium would result in a massive release of energy (quadrillions of BTU) with the end results being perhaps a few grams of helium.
If this speculative hypothesis is correct then hydrogen only needs to be ‘blue-shifted’ in a magnetic field by a small amount for the first fusion product to be created, which would be a ‘weird atom’, along with a release of energy.
Therefore it would have to the case that the very first time this weird atom is created, which exists in a state somewhere between hydrogen and the next known atom, helium, this would blow apart the Standard Model of Particle physics, for you cannot have 1.2 electrons and 1.2 protons, followed by 1.3 electrons and 1.3 protons, etc., etc., until finally you get 2 electrons and 2 protons and a helium atom.
Now if someone was to ask why it is that we have never seen these weird atoms before, my answer would be that such weird atoms are only created temporarily in fusion reactors, such as stars, and that the atoms we are familiar with are created in black-holes, and that black-holes are not fusion reactors, but rather black-holes convert free energy into shrink wrapped packages, little self contained magnetic fields, and that the manner in which this occurs is a linear function. So then out of a black-hole, which operates upon ‘free energy’, you get hydrogen, and then you get helium, but out of a star which works upon atoms, you get hydrogen, then you get a bunch of weird atoms, and release of free energy with each fusion product, and then you get a much smaller amount of helium.
A star then undoes what a black-hole does, in that a black-hole traps energy and shrink wraps it into little electromagnetic bubbles, while a star removes the shrink wrapping, allowing energy to escape before wrapping some up the energy back up in bubbles in consecutive steps. It is for this reason that stars are such massive net losers of energy. Fusion of two atoms is a very inefficient process.
