L'Origen còsmic de la taula periòdica

Authors

  • David Jou i Mirabent

Abstract

Nuclear physics, astrophysics and cosmology describe a history of the chemical elements, formed by nuclear fusion before galaxies (hydrogen and helium), in stars (from helium to iron), or during big explosions of supernovae (beyond iron). With this in mind, the periodic table gains a deep temporal dimension. However, in most of the conceivable universes, matter would not exist, but only radiation, or the periodic table would be reduced to a handful of elements. We close with a few philosophical reflections on matter.
