New AI predicts which planets are going to smash into each other

A team of NASA astrophysicists has put the fate of entire star systems in the hands of an AI algorithm. The system -- dubbed SPOCK -- by NASA and Princeton University astrophysicist Daniel Tamayo, doesn't actually decide which worlds will live and die. But it can predict the paths of exoplanets, and determine which ones will remain stable and which will crash into other worlds or stars, far more accurately and at greater scale than humans ever could. Since the first exoplanet was discovered in 1995, scientists have identified more than 4,000 worlds elsewhere. Over 700 of them are in star systems containing more than one planet, Tamayo said in a press release, which potentially puts them at risk of devastation collisions.
