Changes

Evolutionists Old-Universe advocates believe that the metallicity of such astronomical objects may offer clues to those objects' ages. According to their [[Big Bang|Big Bang theory]], when the universe first formed, it consisted mostly of hydrogen with a sizable proportion of helium; only trace amounts of [[lithium]] and [[beryllium]] are believed to have been created, with no heavier elements forming. Thus, they believe that older stars will have lower metallicity than younger stars, as all other elements were created through stellar and supernova nucleosynthesis.
