Two’s company, three is a crowd: solving a Newtonian pickle
When two (or three bodies of different sizes and distances) orbit a center point, it’s easy to calculate their movements using Newton's laws of motion. However, if all three objects are of a comparable size and distance from the center point, a power struggle develops and the whole system is thrown into chaos. When chaos happens, it becomes impossible to track the bodies’ movements using regular math. Enter the three-body problem. Now, an international team, led by astrophysicist Dr. Nicholas Stone at the Hebrew University of Jerusalem’s Racah Institute of Physics, has taken a big step forward in solving this conundrum. Their findings were published in the latest edition of Nature.
