A black hole with a mass of around 1 M ☉ will vanish in around 2 × 10 64 years. As the lifetime of a black hole is proportional to the cube of its mass, more massive black holes take longer to decay. A supermassive black hole with a mass of 10 11 (100 billion) M ☉ will evaporate in around 2 × 10 93 years. [45]

If black holes evaporate via Hawking radiation, a solar mass black hole will evaporate (beginning once the temperature of the cosmic microwave background drops below that of the black hole) over a period of 10 64 years. [149] A supermassive black hole with a mass of 10 11 M ☉ will evaporate in around 2×10 100 years. [150] Some monster black ...
Black holes don’t gulp up everything at once, but one star’s last light is still gleaming three years later, puzzling astrophysicists.
Given the universe is 13.7 billion years old, that puts the age of this black hole at 13.2 billion years. Even more astounding to scientists, this black hole is a whopper — 10 times bigger than ...
A cosmic mystery surrounding a black hole some 270 million light-years from the Milky Way is deepening. Now, the black hole has once again demonstrated strange features that teams of astronomers ...
By this time, if protons do decay, the Black Hole Era, in which black holes are the only remaining celestial objects, begins. [9] [141] 3.14×10 50 (314 quindecillion) The estimated time until a micro black hole of one Earth mass today, will have decayed into subatomic particles by the emission of Hawking radiation. [147] 10 65 (100 vigintillion)
1972 — Jacob Bekenstein suggests that black holes have an entropy proportional to their surface area due to information loss effects; 1974 — Stephen Hawking applies quantum field theory to black hole spacetimes and shows that black holes will radiate particles with a black-body spectrum which can cause black hole evaporation
