  2. Hawking radiation - Wikipedia

    en.wikipedia.org/wiki/Hawking_radiation

    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.

  3. Primordial black hole - Wikipedia

    en.wikipedia.org/wiki/Primordial_black_hole

    Depending on the model, primordial black holes could have initial masses ranging from 10 −8 kg [17] (the so-called Planck relics) to more than thousands of solar masses. . However, primordial black holes originally having masses lower than 10 11 kg would not have survived to the present due to Hawking radiation, which causes complete evaporation in a time much shorter than the age of the ...

  4. Black hole - Wikipedia

    en.wikipedia.org/wiki/Black_hole

    A black hole is a region of spacetime where gravity is so strong that no matter or electromagnetic radiation, such as light, can escape it. [2] Albert Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. [3] [4] The boundary of no escape is called the event horizon.

  5. Micro black hole - Wikipedia

    en.wikipedia.org/wiki/Micro_black_hole

    A black hole formed in this way is called a primordial black hole and is the most widely accepted hypothesis for the possible creation of micro black holes. Computer simulations suggest that the probability of formation of a primordial black hole is inversely proportional to its mass.

  6. Black-body radiation - Wikipedia

    en.wikipedia.org/wiki/Black-body_radiation

    Hawking radiation is the hypothetical blackbody radiation emitted by black holes, at a temperature that depends on the mass, charge, and spin of the hole. If this prediction is correct, black holes will very gradually shrink and evaporate over time as they lose mass by the emission of photons and other particles. A black body radiates energy at ...

  8. Black hole thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Black_hole_thermodynamics

    In physics, black hole thermodynamics [1] is the area of study that seeks to reconcile the laws of thermodynamics with the existence of black hole event horizons.As the study of the statistical mechanics of black-body radiation led to the development of the theory of quantum mechanics, the effort to understand the statistical mechanics of black holes has had a deep impact upon the ...

    A new study says scientists searching for extraterrestrials might want to focus their attention on emissions from black holes. Here's why. It's Logical That Aliens Are Using Black Holes As ...
