This article considers the origin of the elements and their abundances throughout the universe.
There are, however, differences in chemical composition among stars, and these differences are important in a study of the origin of the elements.
Hoyle himself continued to favour supermassive objects as the origin of the elements over the big bang, but most astronomers saw this work as vindicating big-bang theory.
Although Hoyle was most widely known for this cosmological theory, there is little doubt that his most lasting and significant contribution to science concerns the origin of the elements.
History, moreover, made no more sense; a culture was to be interpreted at one point in time, as if the age and the origin of the elements composing it were without importance.
This includes the nuclear processes by which the lightest elements mostly hydrogen and helium were produced at the explosive birth of the universe (see big-bang model), 13.8 billion years ago, and the subsequent formation of the heavier elements within stars (see chemical element: Origin of the elements).
These results are consistent with the previously suggested common phylogenetic origin of the elements that belong to this clade, although in some cases loss of functionality appears to have occurred and/or perhaps molecular domestication by the host.
Isotope ratios may therefore be used to trace the origin, or source, of the element in question at the time it enters the body.
In particular, S. fleurettii, S. sciuri and S. vitulinus are suggested as a origin of the mecA element of SCC mec elements [ 10].
Although moderate, the correlation between dissolved organic carbon (DOC) and water leachable Ba fraction suggests the biogenic origin of this element in tailings.
