Nuclear physicists from the University of York have discovered a subatomic particle that could have formed the “dark matter” in the universe during the Big Bang. The newly discovered particle is named as d-star hexaquark and comprises six fundamental particles that usually combine in trios to form the protons and neutrons. Researchers also suggest that shortly after the Big Bang, as the universe cooled and expanded to form the fifth state of matter, it ended up combining many d-star hexaquarks. The origin of dark matter in the universe has always puzzled the researchers. Researchers from the University of York consider these findings particularly exciting since it doesn’t require any concepts that are new to physics.
