A cosmologist is someone who studies the universe; cosmology is a branch of astronomy. When describing the composition of stars in astronomical terms, {{w|Metallicity|metals}} are all the elements heavier than {{w|helium}}. This definition of metal is significantly broader than {{w|metal|the one used outside astronomy}}. Likewise, this chart of musical genres describes everything "heavier" than {{w|Pop music|pop}} as metal. The standard conception of elemental metals is a subset of the astronomical conception of metals; likewise, here the musical genre {{w|Heavy metal music|metal}} is presented as a subset of the genres cosmologists consider metal. | A cosmologist is someone who studies the universe; cosmology is a branch of astronomy.
