Is dark energy from cosmic Hawking radiation? – arXiv Vanity

WebNov 21, 2011 · It is suggested that dark energy is the energy of the Hawking radiation from a cosmic horizon. Despite its extremely low Gibbons–Hawking temperature, this radiation could have the appropriate... WebDec 17, 2015 · For a quantum field in inflationary quasi-de Sitter spacetime in Bunch–Davies vacuum state, every freely falling (i.e. geodesic) observer is surrounded by thermal radiation with the Gibbons–Hawking temperature of H 2 π (where H is the Hubble parameter during inflation) , , , , .

Coleman-de Luccia Tunneling and the Gibbons-Hawking …

As mentioned at the beginning, the GHY term is required to ensure the path integral (a la Hawking et al.) for quantum gravity has the correct composition properties. This older approach to path-integral quantum gravity had a number of difficulties and unsolved problems. The starting point in this approach is Feynman's idea that one can represent the amplitude WebMar 19, 2024 · We find that the atom for all the cases behaves as if it were immersed in a thermal radiation at the Hawking temperature from the Kerr black hole. In this regard, one can understand the Hawking effect from the perspective of the geometric phase correction as opposed to that in a flat spacetime, which is unlike the traditional one. WebThe Gibbons-Hawking entropy of the cosmic event horizon dominates the entropy budget of the contents of the event horizon. We have assumed an epoch of inflation and reheating at the Planck time, 10-43 seconds after the big bang. Although, the entropy of the event horizons of super-massive black holes (“SMBHs”) is 1019 roadhouse online ordering
