This　article　investigates　an　N-particle　system　with　the　Newtonian　gravitational　interaction　in　dimensions　n≥　3.　For　the　many-particle　system　without　noise　term,　we　prove　that　there　is　a　finite　time　T　such　that　the　pairs　of　particles　do　collide　with　each　other　for　any　initial　condition.　When　the　noise　effect　is　concerned　and　the　initial　data　are　independent　and　identically　distributed　(i.i.d.),　we　prove　that　pairs　of　particles　do　collide　with　positive　probability:　the　singularity　of　the　drift　is　indeed　visited　in　finite　time,　which　means　that,　for　the　stochastic　N-particle　system　interacting　via　the　Newtonian　gravitational　potential,　global　strong　solution　dose　not　exist.　©　2021,　The　Author(s),　under　exclusive　licence　to　Springer　Nature　B.V.
