Slowly rotating black hole
WebbThe basic principle is that because of the curvature of spacetime around a black hole, the amount of "distance" a beam of light has to cover is greater near a black hole. However, … WebbC) They are rapidly rotating black holes whose precession points their poles toward us on occasion. D) They are violent energy sources known to lie at the heart of the Milky Way and similar massive galaxies. E) They are neutron stars on which accreted matter builds up, then explodes in a violent nuclear explosion. E
