Conformal cyclic cosmology (CCC) is a cosmological model in the framework of general relativity and proposed by theoretical physicist Roger Penrose. [1] [2] [3] In CCC, the universe iterates through infinite cycles, with the future timelike infinity (i.e. the latest end of any possible timescale evaluated for any point in space) of each previous iteration being identified with the Big Bang ...
Hawking radiation is black body radiation released outside a black hole's event horizon due to quantum effects according to a model developed by Stephen Hawking in 1974. [1] The radiation was not predicted by previous models which assumed that once electromagnetic radiation is inside the event horizon, it cannot escape.
The Hawking singularity theorem is based on the Penrose theorem and it is interpreted as a gravitational singularity in the Big Bang situation. Penrose shared half of the Nobel Prize in Physics in 2020 "for the discovery that black hole formation is a robust prediction of the general theory of relativity".
Stephen William Hawking (8 January 1942 – 14 March 2018) was an English theoretical physicist, cosmologist, ... he felt there was little point. [73] ...
Hawking–Page phase transition, a theoretical predicted phase transition in AdS black holes, named after Hawking and Don Page. Hawking point, a theoretical prediction of conformal cyclic cosmology. Hawking radiation, a theoretical type of radiation emitted by black holes evaporating, first conceived by Hawking, and subsequently named for him. [4]
At present, it is expected by the Hawking radiation mechanism that the primary impact of quantum effects is for event horizons to possess a temperature and so emit radiation. For black holes, this manifests as Hawking radiation, and the larger question of how the black hole possesses a temperature is part of the topic of black hole thermodynamics.
Hawking spoke with WIRED on a wide range of topics in a new interview, directly addressing Trump's stance on climate change -- arguably unsurprising given his well known concerns over our planets ...
On the Origin of Time is a 2023 book by physicist Thomas Hertog about the theories of Stephen Hawking. [1] Hertog is a Belgian cosmologist working at KU Leuven university, who worked extensively with Hawking. [2] He wrote the book at Hawking's request to popularize the top-down cosmological theory that they had developed together. [3]
