On the Origin of Time is a 2024 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 cosmological theory that they had developed together.
WebNov 6, 2024 · In essence, the Unruh effect is about a single stationary spacetime and you are comparing two different family of observers. The Hawking radiation is about an evolving spacetime and what a single family of observers measure. The result are … WebFeb 20, 2024 · The Hawking Effect Stephen Hawking showed in the early 1970s that black holes emit thermal radiation with a temperature inverse to the black hole’s mass. This Hawking effect is a consequence of the relativity of the particle number. An observer falling into a black hole would not measure any particles and think the black hole is surrounded …
WebJul 20, 2024 · However, the Hawking effect still occurs if we replace the vacuum with a different state, which is called stimulated radiation. The stronger stimulated effect is obtained if we replace vacuum with a classical state. This is classical stimulated Hawking radiation and is the usual effect studied in optical analogues. In this case, we use a … WebMar 7, 2008 · Furthermore, one can discriminate the Hawking effect from other nonlinear optical processes, such as four-wave mixing, because it is not subject to their phase-matching conditions . Moreover, in addition to observing Hawking radiation per se, one could detect the correlations of the Hawking partners—a feat that is impossible in …
