4 days ago · Thomas Hertog tells us how he collaborated with Stephen Hawking on his final theorem — a Darwinian revolution in physics that explains the origin of time. In 2002, Thomas Hertog, then a ...
2 days ago · The Hawking radiation for an astrophysical black hole is predicted to be very weak and would thus be exceedingly difficult to detect from Earth. A possible exception, however, is the burst of gamma rays emitted in the last stage of the evaporation of primordial black holes.
5 days ago · Door-to-door hawking prohibited (The Straits Times, 24 June 2024) We refer to the letter “Stop door-to-door sales” (June 14). The door-to-door sale of food or goods to consumers is a form of illegal hawking, which is an offence under the Environmental Public Health Act. The Singapore Food Agency (SFA) will investigate cases of illegal ...
2 days ago · Figure 1. The transition amplitude as a function of the atomic energy gap for the Hartle-Hawking state. The red solid line denotes the process in which the detector absorbs a photon from the field and then jumps from the ground state to the excited state, and the blue dashed line denotes the process in which the field excites a photon while the detector jumps to the excited state.
5 days ago · Stephen Hawking was a gem in the realm of theoretical physics. With over a hundred papers published, he had some of the most groundbreaking discoveries in the field of cosmology. Here are some of the most popular theories that Stephen Hawking made in his lifetime.
2 days ago · The Role of God in Creation. Hawking questioned the necessity of God in the creation of the universe. He proposed that the Big Bang, a spontaneous event, could occur due to the laws of physics ...
3 days ago · Hawking star transmutes an asteroid-mass PBH into a stellar mass black hole. Even in the absence of PBHs, it is also worth noting that some particle dark matter candidates could also produce Hawking stars if a suffi-ciently large dark matter halo becomes bound to a star and relaxes to form a compact core (e.g.Ge et al.2024).
