2002 — Physicists at The Ohio State University publish fuzzball theory, which is a quantum description of black holes positing that they are extended objects composed of strings and don't have singularities. 2002 — NASA's Chandra X-ray Observatory identifies double galactic black holes system in merging galaxies NGC 6240
The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.8 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.
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 .
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 ...
History of black holes. Timeline of black hole physics – Timeline of black hole physics; John Michell – geologist who first proposed the idea "dark stars" in 1783 [3] Dark star; Pierre-Simon Laplace – early mathematical theorist (1796) of the idea of black holes [4] [5] Albert Einstein – in 1915, arrived at the theory of general relativity
10 43 (10 tredecillion) years to approximately 10 100 (1 googol) years, up to 10 110 years for the largest supermassive 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 ...

Black-hole cosmology is a cosmological model in which the observable universe is the interior of a black hole existing as one of possibly many universes inside a larger universe. [89] This includes the theory of white holes, which are on the opposite side of space-time.
