Physicists crack unsolvable three-body problem using drunkard’s walk

by

A physics problem that has plagued science since the days of Isaac Newton is closer to being solved, say a pair of Israeli researchers. The duo used “the drunkard’s walk” to calculate the outcome of a cosmic dance between three massive objects, or the so-called three-body problem. For physicists, predicting the motion of two massive … Read more
