It has been proposed by Edward P. Tryon that the Universe may be a large scale quantum mechanical vacuum fluctuation where positive mass-energy is balanced by negative gravitational potential energy, as a consequence of the early inflationary launch of the expansion of the Universe, in which these quantum fluctuations particles got amplified, which would explain how our Universe could have inflated from these particles. But what particle(s) exactly? What initial particle is being referred to here? It is known that light preceded matter, so bosonic energy, chronologically speaking, could have been the first elementary particle to give rise to all the other particles that formed from it later. The Big Bang theory is said to have started from one single point. If I’m understanding it correctly, this hypothesis referring to that 1 point as being only 1 particle. Of course, it seems more probable that the Universe started out with one particle, rather than a bunch of particles to start out with, but that does not mean that this hypothesis therefore has to be correct. When a photon is scattering with matter or antimatter, part of energy from the photon is given to matter/antimatter, and a new photon with smaller energy is created. A particle which received energy from photon is accelerated. It can be repeated over and over again, and from an initial 511 KeV photon after millions of such interactions, you will have millions of photons with very low energies (e.g. visible spectrum, then infrared). But wait a minute, a photon that preceded all other particles? To suggest that an electromagnetic particle such as the photon could have been the first particle before all the other particles, from which the strong and weak force came forth later, that has to be backed up with scientific facts, observations and maths. It has already been proven that the electroweak force once preceded electromagnetism and the weak force. Concerning the strong force, which is carried out between protons and neutrons, when for instance a neutron decays, electromagnetism does indeed “show up” (a neutron decays into proton, electron and antineutrino). Again, there seems to be electromagnetism involved. However, this does not mean that the strong force came after electromagnetism, and this hypothesis therefore has to be true. I’d like to know if anyone here could provide me with facts in favour of this hypothesis, or against this. The law of conservation of energy forbids new energy to be added (because energy can neither be created nor destroyed), so the suggestion that a boson, like the photon, could have pair produced two matter/antimatter particles (a gamma photon is able to create a pair of electron-positron must have at least 1.022 MeV energy) seems to be the only remaining option to explain the vast amount of matter and energy in the Universe we have today, because this conservation law has to be satisfied, since new energy could not have been generated/added, therefore the existing energy could only have been changed/divided. The question how this first bosonic energy could have been in existence in the first place is the domain of philosophy, not science, so I won’t make any suggestions about that mystery, I’m only trying to find out the chronology of the Big Bang, and what happened after that first initial particle. If this hypothesis is true (which I’m not so sure about yet), taking inverse Compton scattering in account (in which a charged particle transfers part of its energy to a photon), it’s not quite clear to me how to get from an electron/positron pair to, well, more than an electron/positron pair, because they can’t divide any further, can they?
