Pair instability supernovae
WebSep 29, 2024 · Pair-instability supernova explosions happen when photons in the center of a star spontaneously turn into electrons and positrons — the positively charged antimatter counterpart to the electron. This conversion reduces the radiation pressure inside the star, allowing gravity to overcome it and leading to the collapse and subsequent explosion.
