Created AI that can predict collisions of celestial bodies

The system is called SPOCK. Her task: to predict the orbits of exoplanets and determine which ones

will remain stable, and which will collide with other planets or stars.

For most multi-planet systems, there ismany possible orbital configurations, some of which can lead to collisions of bodies. Many of these development paths, possibly in a few million years, will turn the system into a ball of intersecting orbits. The aim of the study was to eliminate these so-called “quick instabilities”.

We cannot say for sure: this planetary system will explode soon. The goal of this AI is to eliminate all planets that have already survived the collision and do not currently exist.

Performing this calculation using the previous methods would take more than a year of computer time. The SPOCK model did it in 14 minutes. Image: Daniel Tamayo

According to Tamayo, the new method will provide a clearer picture of the orbital architectures of planetary systems outside of our universe.
