Passage: 101500 years from nowIn 101500 years, cold fusion occurring via quantum tunnelling should make the light nuclei in ordinary matter fuse into iron-56 nuclei (see isotopes of iron). Fission and alpha particle emission should make heavy nuclei also decay to iron, leaving stellar-mass objects as cold spheres of iron, called iron stars.

Question: What is the name for the cold spheres of iron created when heavy nuclei decay?
iron stars
