Painlevé conjecture
Physical theorem / From Wikipedia, the free encyclopedia
In physics, the Painlevé conjecture is a theorem about singularities among the solutions to the n-body problem: there are noncollision singularities for n ≥ 4.[1][2]

The theorem was proven for n ≥ 5 in 1988 by Jeff Xia[3][4] and for n=4 in 2014 by Jinxin Xue.[5][6]
