How to cross the event horizon of a black hole
Black holes are massive stares. Gravitational force around the black hole is so high that even light cannot escape it. The edge of black hole is known as event horizon. If you can somehow reach to the event horizon, pull of gravity will turn you into spaghetti before you can reach to the black hole. This is known as spaghettification problem. However, some suggest that a supper massive black hole may solve the spaghettification problem and you may be able to pass through a black hole alive someday. Edited by Ashraf
