6 hours ago · In 1974, Hawking predicted that black holes are not entirely black but emit small amounts of thermal radiation at a temperature ħc 3 /(8πGMk B); this effect has become known as Hawking radiation. By applying quantum field theory to a static black hole background, he determined that a black hole should emit particles that display a perfect black body spectrum .

3 days ago · To address this gap, Udalski and colleagues re-analysed their data. If black holes of 10 solar masses made up all the dark matter in our cosmic neighbourhood, they calculated that OGLE should have detected 258 microlensing events. If dark matter was instead composed of 100- or 1000-solar-mass black holes, the survey should have yielded 99 or 27 ...
4 days ago · Stephen Hawking, a renowned theoretical physicist and cosmologist, made groundbreaking contributions to our understanding of black holes and the universe. His discovery of Hawking radiation revolutionized the study of black holes, and his work on the Big Bang theory provided critical insights into … 00:04:34. CLIP.
2 days ago · In 1924, Bell Labs physicist Walter A. Shewhart proposed the control chart as a method to determine when a process was in a state of statistical control. Shewhart's methods were the basis for statistical process control (SPC): the use of statistically based tools and techniques to manage and improve processes.
1 day ago · Abstract. We propose a new formula for the entropy of a dynamical black hole—valid to leading order for perturbations off of a stationary black hole background—in an arbitrary classical diffeomorphism covariant Lagrangian theory of gravity in dimensions. In stationary eras, this formula agrees with the usual Noether charge formula, but in ...
