What is No-hair theorem?
The '''no-hair theorem''' is about [[black holes]]. [[Black hole]]s can be described by just three visible properties: [[mass]], [[electric charge]], and [[angular momentum]], or [[spin (physics)|spin]]. The theory itself was first stated by [[Werner Israel]], a [[Canadian]] [[physicist]]. Then [[John Archibald Wheeler]] said that black holes have no hairs. This gave the idea its name. What he meant was: except for these three properties, ''no other properties can be got from a black hole''.<ref> Misner, Charles W; Thorne, Kip S. & Wheeler, John Archibald 1973. ''Gravitation''.
