W ithout collisions could the Newtonian n-body problem of point masses eject a particle to infinity in finite time? This intriguing century-old concern, which has motivated several interesting and deep mathematical conclusions, was recently resolved by Xia ([X1, 2]) in his Ph.D. dissertation; he proved that three-dimensional examples exist for all n ≥ 5. Later, Gerver [G] asserted that a similar behavior occurs with the planar 3n body problem but with an unknown and very large n value. Even the… Expand
