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
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.
After 10 43 years, black holes will dominate the universe. They will slowly evaporate via Hawking radiation. [5] 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.
In 1974, Stephen Hawking made one of his most famous predictions: that black holes eventually evaporate entirely.According to Hawking's theory, black holes are not perfectly "black" but instead ...
The Black Hole Era is defined as "40 < n < 100". In this era, according to the book, organized matter will remain only in the form of black holes. Black holes themselves slowly "evaporate" away the matter contained in them, by the quantum mechanical process of Hawking radiation. By the end of this era, only extremely low-energy photons ...
A black hole with the mass of a car would have a diameter of about 10 −24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more than 200 times that of the Sun. Lower-mass black holes are expected to evaporate even faster; for example, a black hole of mass 1 TeV/c 2 would take less than 10 −88 ...
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)
Far in the future, past the death of the Sun and the annihilation of the Earth, everything will simply evaporate. Skip to main content. Sign in. Mail. 24/7 Help. For premium support please call: ...
