Dueterium found in the universe matches that which was predicted to exist due to the big bang edit
First, Deuterium abundance does not have a current known cosmological explanation and is therefore associated with the big bang as this is the only force capable of creating an abundance. The same is true for other rare elements. Second, the discovery of blue dwarf galaxies that have an abundance of light elements such as helium and a scarcity of heavy elements such as oxygen and neon show that these are young systems, which is significant due to their positioning [1].
Methods edit
The author theorized that the amount of deuterium found in the universe in present day could only be explained by the occurrence of a large cosmological event, namely the big bang. The author then measured the amount of deuterium in the universe [1]
Results edit
The amount of deuterium found in the universe was found to be too large to be explained by any known cosmological events combined. It is then deduced that even the most simple big bang models could account for this abundance[1].
