<br />
{{w|Metallicity|Metals}}, in astronomy, are stellar elements heavier than {{w|helium}}. This definition of metal is significantly broader than {{w|metal|the one used by scientists outside astronomy}}. Likewise, this chart of musical genres describes everything "heavier" than pop as metal. The standard conception of elemental metals is a subset of the astronomical conception of metals; likewise, the musical genre metal is also a subset of the genres astronomers consider metal.<br />
<br />
The title text refers to the {{w|Big Bang}}. At roughly 10<sup>-32</sup> seconds after the Big Bang, the inflationary epoch ended, causing a large amount of quarks, anti-quarks and gluons to come into existence. In inflationary cosmology, this point is considered to be the end of the Big Bang. The author jokingly refers to it as "post-" because literally nothing existed before the Big Bang.<br />
