This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses (M ☉), approximately 2 × 10 30 kilograms. Introduction Comparisons of large and small black holes in galaxy OJ 287 to the Solar System
While multiple causes may have contributed to many mass extinctions, all the hypothesized causes have two things in common: they cause major changes in Earth systems — its ecology, atmosphere, surface, and waters — at rapid rates. Here are some hypothesized causes for each of Earth’s biggest mass extinctions: End-Ordovician:
