Deuterium’s creation was the first step in Big Bang nucleosynthesis, a sequence of nuclear reactions that occurred when the cosmos was a super hot but rapidly cooling soup of protons and neutrons.

If two [dark neutrons] can form a bound state (dark dineutron), bigger nuclei of pure [dark neutrons] can form during dark Big Bang Nucleosynthesis, and can grow to be very large due to the lack ...
