A black hole cosmology (also called Schwarzschild cosmology or black hole cosmological model) is a cosmological model in which the observable universe is the interior of a black hole. Such models were originally proposed by theoretical physicist Raj Kumar Pathria , [ 1 ] and concurrently by mathematician I. J. Good .
A quasi-star (also called black hole star) is a hypothetical type of extremely large and luminous star that may have existed early in the history of the Universe. They are thought to have existed for around 7–10 million years due to their immense mass .
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 ...
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 ...
Astronomers have discovered what may be the brightest object in the universe, a quasar with a black hole at its heart growing so fast that it swallows the equivalent of a sun a day. The black hole ...
A conjectured star from the early universe with a black hole at its center. none: The universe is too old for this object to come into existence. Strange star: A form of quark star, a neutron star with strange matter at its core, or star which is a ball of strange matter. none: Thorne–Żytkow object: A red giant or red supergiant whose core ...
[9]: 75 The concept would subsequently be further popularized through its use in the Star Wars franchise. [11] In the 1974 film Dark Star, special effects designer Dan O'Bannon created a visual effect to depict going into hyperspace wherein the stars in space appear to move rapidly toward the camera. This is considered to be the first depiction ...
Of course what comes out of the other side of a black hole would unlikely resemble what went in. According to the Boston Globe , on the matter, Hawking noted , "It's like burning an encyclopedia.
