The vast majority of deuterium merged for making helium, and trace amounts of lithium were being also produced.
Chief nuclear reactions liable for the relative amounts of light atomic nuclei noticed during the Universe. Other observations are not Evidently answered by recognised physics. In accordance with the prevailing principle, a slight imbalance of issue above antimatter was present during the universe's creation, or made incredibly shortly thereafter.
