A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape from it. This is due to the immense mass and compactness of the object.
Black holes are formed when a massive star dies and its core collapses under its own gravitational force. This creates a singularity, a point of infinite density, at the center of the black hole.
No, nothing can escape from the event horizon of a black hole. However, outside of the event horizon, it is possible for objects to escape if they have enough velocity to overcome the gravitational pull.
Once an object passes the event horizon of a black hole, it is pulled towards the singularity and stretched into a long, thin strand in a process known as spaghettification. Eventually, the object will reach the singularity and be crushed to an infinitely small point.
According to current scientific theories, black holes do not die. However, they can slowly lose mass over time through a process called Hawking radiation, which is the emission of particles from the black hole's event horizon.
