The Higgs Appears
Higgs and other physicists believe that initially the Universe had no mass at all. We have seen that any particle has a rest energy (or Einstein energy) of E and a potential energy (or Newton energy) of U. If we add them together:
E + U = 0
The total energy is just 0! This result applies to any particle, from the smallest electron to the most massive Black Hole. It even applies to massless particles like the photon. The total energy of our big Universe is just zero. It's the ultimate free lunch, which explains how the Universe could evolve from a tiny point into the immensity we observe today.
The first mass took the form of singularities, which formed fro tiny quantum fluctuations grown large by the rapid expansion of the Universe. The protons, electrons and neutrons that we are made of came later, and today form 4.507034% of the Universe. Perhaps the Higgs field or boson gave this portion mass.
The standard model of particle physics has been mostly successful in describing the microscopic world. As physicists have moved into astronomy, they have come up with their own standard model. Cosmology's model consists of ethereal energies: a repulsive "inflaton" near the Big Bang, another repulsive "dark energy" driving current acceleration, and our Ptolemaic world in the middle. None of these epicycles can be observed in nature.
Experience can make one suspicious of "standard models." Who is this Mr. Standard? Why doesn't he show his face at conferences? How many years did he labour in darkness while physics ignored his Standard Model? How much hard work was required for Standard's Model to be accepted? Did a Mrs. Standard do all the real work? The idea of "standard models" is suspiciously like groupthink, which led to "dark energy" and other messes.
Though no one has found his boson yet, best wishes to Peter Higgs. The mass problem is an omission that needs to be solved. Higgs has waited long enough for his hypothesis to be tested. Even if the Higgs field or boson is not found, it will lead to new ideas in physics. Thankfully we need not wait until age 78 to show that the speed of light is slowing.
