Sarah Millholland, MIT physics professor and Kavli Institute member, is the 2024 Vera Rubin Early Career Award recipient for her wide-ranging contributions to the formation and dynamics of extrasolar planetary systems.

If a super-advanced civilization had to ability to engineer the solar system from scratch, how many planets could they squeeze around the sun?

Reset A fresh, abstract approach to solving the statistical model for the famous “three-body problem”. This promising idea tackles chaos between co-orbiting bodies by treating space as an eight-dimensional region. Order out of chaos Isaac Newton’s three laws of motion can elegantly describe the basic physics of how things interact in the universe. These equations can be used to describe how Earth orbits the sun or how the moon orbits the Earth. However, when Newton tried to introduce a...

The three-body problem refers to astronomers inability to track the collision course of three stars hurtling toward one another through space. To better predict the fates of these celestial bodies, the secret is to treat space like a leaky balloon made of Swiss cheese. Picture Earth and the moon careening together around the solar system. Its clear what will happen as the moon continues to circle our planet, completing its full orbit each month. Now picture—as in the 2011 film Melancholia—...

Novel Theory Addresses Problem Predicting Three Orbiting Bodies in Space April 13th 2021, 12:09 pm Newton first became interested in the problem of predicting the motion of three bodies moving in space under the influence of their mutual gravitational attraction Image Credit: Share Email The ‘three-body problem,’ the term coined for predicting the motion of three gravitating bodies in space, is essential for understanding a variety of astrophysical processes as well as a large class of mech...
