Thus, near the Big Bang singularity, the structure of spacetime ceases to be smooth. Mathematical theorems suggest that spacetime becomes overwhelmed by "gnarly" features: hooks, loops and bubbles.

But a team of researchers has proposed a new idea.They argue that our inflation and Big Bang Nucleosynthesis eras were not alone. Dark matter may have evolved along a completely separate trajectory.

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.

But not all the matter formed by Big Bang nucleosynthesis condensed in its lowest-energy state. As high-energy matter settled into its lowest-energy state, it released that energy in the form of ...

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 ...

In other words, the theory of cosmic inflation suggests that right before the Big Bang, a faster-than-light expansion of the universe occurred in the fraction of a second.

In physical cosmology, Big Bang nucleosynthesis (or primordial nucleosynthesis) refers to the production of nuclei other than H-1, the normal, light hydrogen, during the early phases of the ...
