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 ...

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 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 ...

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.

At least, we thought that was the story: the Universe was born a finite amount of time ago, and started off with the Big Bang. Today, however, we know a whole lot more than we did back then, and ...

The energies involved in the accelerators are about a factor of 10 or more higher than expected during Big Bang nucleosynthesis, so the rates we get out of these experiments are probably not very ...

The Big Bang Theory explains how the universe began with an infinitely hot and dense single point ... He-3, Li-7, and Deuterium). These were formed during the era of Big Bang Nucleosynthesis ...

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 ...

Big Bang nucleosynthesis; Ultimate fate of the universe; Dark matter; Dark energy; Space & Time News. June 9, 2025. Black Holes Could Act as Natural Supercolliders -- And Help Uncover Dark Matter.

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 ...
