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
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. [151] A supermassive black hole with a mass of 10 11 M ☉ will evaporate in around 2×10 100 years. [152] Some monster black ...
A black hole of one solar mass (M ☉ = 2.0 × 10 30 kg) takes more than 10 67 years to evaporate—much longer than the current age of the universe at 1.4 × 10 10 years. [22] But for a black hole of 10 11 kg, the evaporation time is 2.6 × 10 9 years. This is why some astronomers are searching for signs of exploding primordial black holes.
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 ...
Black holes don’t gulp up everything at once, but one star’s last light is still gleaming three years later, puzzling astrophysicists.
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]
By: Patrick Jones. A 30-year-long question about black holes has finally been resolved. Apparently, black holes twist space time like taffy. This finding is based off a principle put forward by ...
