You’re made of atoms.
The fact that you’re not all hydrogen means that your home star (in your case, the Sun), is made from recycled material. In fact, the Sun is made from atoms that have come into being over several star’s lifecycles; Star is born, star manufactures new and different atoms in its core, star explodes. A new star is made from the materials and new atoms from the exploded star. Rinse. Repeat. Do this for 14 billion years.
In this podcast, I speak with Dr. John Barrow, Professor of Mathematical Sciences in the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge in England about the evolution and “archeology” of the known universe.
