Black holes are enormous cosmic bodies with immense gravitational pull. Over time black holes keep sucking in matter around it and keep getting bigger and bigger. Do black holes die or continue for ever ? As black hole feed on matter, principles of quantum mechanics eventually lead to demise of black holes.
In quantum mechanics, subatomic positive and negative particles are continuously created and annihilated into energy. At times when these particles are created at event horizon gravity of black hole pull in negative particles while positive particles end up escaping into the space. This phenomena was first described by Stephen Hawking thus also known Hawking’s radiation. Over time, the black hole emits energy in from of positive particles leading to lose of mass. Black holes will continue to loss its mass and eventually evaporate to nothing and/or they may become unstable cosmic bodies eventually ending with explosive gamma rays bursts.
