If this went on for a length of time, most of the antimatter in the universe would have disappeared. They further noted, reported Science X : “that a lot of those particles that made up that matter would meet with antimatter particles, resulting in the annihilation of both. Physicists from Brookhaven National Laboratory and the University of Kansas suggest that a stream of matter was being created by the three particles as they decayed just after the Big Bang. ![]() “Mystery Moment in Time” –The Observable Universe’s Missing Antimatter Physicists believe that there were equal amounts of matter and antimatter in the early history of the universe – so how did the antimatter vanish? When an electron and positron collide, they annihilate each other, producing a pair of photons that conserve energy and momentum. For example, the positively charged positron is the antimatter counterpart of the negatively charged electron. Particles of antimatter have the same mass but opposite electrical charge of their matter counterparts. ![]() Such gaps have inspired physicists to search from subatomic particles to galaxies for laws of nature beyond the Standard Model. The Standard Model fails to explain why the observable universe contains virtually no antimatter. I cannot imagine how breathtaking the world would be when we master and control luminous matter and dark matter.” ![]() Even better, through our great control of the Higgs boson production at the Large Hadron Collider and future colliders, we might even directly produce dark-world particles and detect them. “Through such coupling, we might directly observe the decay or transitions between different states of particles that exist in the dark world. “Higgs boson, a critical component of the Standard Model that helps enable many dynamics, could also play the role of the portal between the luminous world and the dark world through its quantum mechanical couplings,” Liu wrote in his email. We cannot associate the dark energy to either world (yet) as it is another mystery of our universe.” Given Einstein’s mass-energy equation, there is more energy in the dark world than in our luminous world. “Why do we expect DM to be a single species, lifeless, dull, and boring? It is entirely reasonable, even more probable, to have a dark world built upon the dynamics of dark matter. “Ordinary matter only makes up about 15% of the matter content of our universe dark matter (DM) makes up the rest of the matter content,” he explained. “Our ordinary matter (baryonic matter) enabled us to have such a rich and beautiful world,” astrophysicist Zhen Liu at the University of Minnesota wrote in an email to The Daily Galaxy. The Dark World May Not Be Built on a Single Species ![]() The Higgs boson may also reveal insights into the nature of dark matter and dark energy, the so-called “dark sector” that comprises 95% of the Universe. In 2019, researchers proposed that three types of very high-energy Higgs Bosons, dubbed the “Higgs Troika”, may have played a role in ridding the infant universe of most of its antimatter. The discovery of the Higgs boson in 2012 has proved to be a source of rich speculation for particle physicists.
