Were it not for cosmic good fortune, we wouldn't be here
Did our solar system get lucky? The delicate equilibrium that enables Earth to host life is a remnant of a violent and explosive past. Astrophysicists have been investigating the solar system's formation to discover why our planet wasn't swept into the dustbin of space like so many were before it, with dynamical instability being one of the main circulating theories. However, a breakthrough 2022 study by Sean Raymond, Beibei Liu and Seth Jackson rewrites this concept and explains what led to our cosmic good luck.
