An example of metaphor in popular science writing:
"… lithium – a chemical born at the start of the universe – is found all around us, in the crust of the earth upon which we live."
de Moore, G., & Westmore, A. (2016). Finding Sanity. John Cade, lithium and the taming of bipolar disorder. Allen & Unwin.
n.b., Current understanding of the big bang is that it led to hydrogen, helium, and a (relatively) small amount of lithium being produced`. (Though not immediately – the conditions immediately after ther big bang were too extreme for any elements to form.) Some of the lithium in the universe today therefore resulting directly from the big bang, although most was created later in stars.
