A region of space-time from which prevents anything as well as light from escaping is called a black hole. There is a defined surface called an Event Horizon that is a point of no return around it. Karl Schawrzchild discovered in 1916 the first modern solution of general relativity which characterizes a black hole. The black holes are formed by massive stars collapse at the end of a star’s end life cycle. It can continue to grow by absorbing mass from its surroundings. The black hole has three independent properties: mass, charge, and angular momentum. However, you can escape out of a black hole through a wormhole, but you’ll be traveling in another universe. Nothing can escape from a black hole.
