These inward and outward forces maintain balance and hold the star together. However, when the star runs out of fuel, there are no hot gases and radiation. Hence, there is no outward force to balance the inward pull of gravity and thus, the star begins to die. The star's core begins to collapse under its own gravity. This collapse causes the outer layers to blow apart in a huge explosion called a supernova. Now, it is estimated that if a star has at least 20 times more mass than our sun, then the star collapses to form a black hole. The surface or boundary of a black hole is called event horizon. Nothing can escape from within the event horizon of a black hole, not even light.
