Cosmologist Genres
Cosmologist Genres
A cosmologist is someone who studies the universe; cosmology is a branch of astronomy. When describing the composition of stars in astronomical terms, metals are all the elements heavier than helium . This definition of metal is significantly broader than the one used 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, here the musical genre metal is presented as a subset of the genres cosmologists consider metal.
Randall may have decided to portray pop music in a similar way to the elements helium and hydrogen as a reference to the " pop test ", the test for hydrogen as a product of a chemical reaction.
Cosmologists also study the history and future of the universe, and the title text refers to the Big Bang . At roughly 10 -32 seconds after the Big Bang, the inflationary epoch ended, causing a large number 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. Randall jokingly refers to it as "post-" because nearly the entire history of the universe is after this instant. This is a reference to types of music with "post-" in their names, e.g. post-rock , post-punk , post-metal .
