2 giorni fa · e. Stephen William Hawking (8 January 1942 – 14 March 2018) was an English theoretical physicist, cosmologist, and author who was director of research at the Centre for Theoretical Cosmology at the University of Cambridge. [6] [17] [18] Between 1979 and 2009, he was the Lucasian Professor of Mathematics at Cambridge, widely viewed as one of ...

9 apr 2024 · The team’s conclusion stunned the physics community, as it constituted the most quantitative direct advance toward resolving the longstanding black hole information paradox — a conundrum raised in the work of physicist Stephen Hawking.
1 giorno fa · Quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is of the order of billionths of a kelvin for stellar black holes , making it essentially impossible to observe directly.
5 giorni fa · Quantum Field Theory in Curved Spacetime: Stephen Hawking applied quantum field theory to the curved spacetime around black holes. He proposed that particle-antiparticle pairs are constantly forming near the event horizon.
7 apr 2024 · She uses black holes to explore the physical feasibility of wormholes: theoretical passages or tunnel-like structures that connect separate points in spacetime. Stephen Hawking proposed that black holes emit energy via quantum particles, causing them to eventually evaporate and challenge the conservation of information.
2 giorni fa · In the past two decades, the exploration of quantumness within Schwarzschild spacetime has garnered significant interest, particularly regarding the Hawking radiation’s impact on quantum correlations and quantum coherence. Building on this foundation, we investigate how Hawking radiation influences maximal steered coherence (MSC)-a crucial measure for gauging the ability to generate ...
4 giorni fa · 1992 – Stephen Hawking states his chronology protection conjecture. 1993 – Demetrios Christodoulou and Sergiu Klainerman prove the non-linear stability of the Minkowski spacetime. 1995 – John F. Donoghue show that general relativity is a quantum effective field theory.
