Nuclear physicists at the University of York have recognized a sub-atomic particle that could have produced the “dark matter” in the Universe during the Big Bang. The particle contains six quarks, the fundamental particles that normally link in trios to make up protons and neutrons. The team proposes that in the situations shortly after the Big Bang, many d-star hexaquarks could have arranged together as the universe cooled and extended to form the fifth state of matter. The next step to establish this new dark matter candidate will be to gain a better knowledge of how the d-stars communicate, when do they attract and when do they oppose each other.
