How did everything begin? It's a question that humans have pondered for thousands of years. Over the last century or so, ...

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 ...

Scientists are looking into the Dark Big Bang, a second event that sent dark matter particles out into the universe., and we may be able to find evidence of it.

Big Bang nucleosynthesis also enabled physicists to predict the number of different types of neutrinos, which helped drive cosmic expansion.

And we’ve successfully measured the primordial abundances of the light elements, finding a spectacular agreement with the predictions of Big Bang nucleosynthesis.

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 ...

One theory is that dark matter resides in a “dark mirror” universe that failed to form atoms during the nucleosynthesis of the Big Bang.

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.

The Big Bang is the cosmological model of the universe whose primary assertion is that the universe has expanded into its current state from a primordial condition of enormous density and ...
