Can a black hole die?
Black holes are regions of space-time where gravity rules: The gravitational pull of a black hole is so strong that nothing, not even light, can escape. But even the black holes will one day die. And when they do, these monsters won’t go gently into the night.
Will our Sun become a black hole?
However, the Sun will never turn into a black hole, because it is said to have less mass than needed to turn into one. When the Sun is about to reach its end and run out of its fuel, it will automatically throw off outer layers turning into a glowing gas ring known as a “planetary nebula”.
