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.
A black hole is a massive, compact astronomical object so dense that its gravity prevents prevents anything from escaping, even light. Albert Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. [2] [3] The boundary of no escape is called the event horizon.
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 ...
Scientists say microscopic black holes could explain the elusive "dark matter" that makes up a quarter of all matter in the universe. But can it be proven?
Extremal black hole – black hole with the minimal possible mass that can be compatible with a given charge and angular momentum. Black hole electron – if there were a black hole with the same mass and charge as an electron, it would share many of the properties of the electron including the magnetic moment and Compton wavelength.
In astronomy, the term compact object (or compact star) refers collectively to white dwarfs, neutron stars, and black holes. It could also include exotic stars if such hypothetical, dense bodies are confirmed to exist. All compact objects have a high mass relative to their radius, giving them a very high density, compared to ordinary atomic matter.
Hypothetical black hole may refer to: Micro black hole, a microscopic black hole proposed to have formed in the early universe; Intermediate mass black hole, a black hole of a mass between a stellar mass black hole and a supermassive black hole; Direct collapse black hole: a black hole formed from the collapse of hydrogen, rather than from a star
Primordial black holes as a dark matter candidate has the major advantage that it is based on a well-understood theory (General Relativity) and objects (black holes) that are already known to exist. However, producing primordial black holes requires exotic cosmic inflation or physics beyond the standard model of particle physics , [ 125 ] and ...
