An example of metaphor in public science discourse:
"When the universe started, essentially all that came out of the big bang in chemical terms was hydrogen, helium and a tiny little bit of lithium. And all the [other] chemical elements that are in the universe have formed since that time, in various processes, in normal stars; in supernovae explosions of stars; some possibly in the murder of neutron stars."
Prof. Mike Edmunds
Mike Edmunds (Emeritus Professor of Astrophysics at Cardiff University and President of the Royal Astronomical Society) was being interviewed on an episode ('Mike Edmunds on decoding galaxies and ancient astronomical artefacts') of the BBC's 'The Life Scientific'.
