- They began with the singularity theorems in the 1960s followed by his discovery that black holes have an entropy and consequently a finite temperature. Black holes were predicted to emit thermal radiation, what is now called Hawking radiation. He pioneered the study of primordial black holes and their potential role in cosmology.
Jun 4, 2024 · Hawking and Hartle used quantum fluctuations in inflaton fields to explain how our universe emerged with the uniformity we observe across vast scales. In simpler terms, the work connected quantum mechanics with cosmology in a groundbreaking way to explain how our ordered universe arose from microscopic quantum uncertainties.

Mar 14, 2018 · Despite being diagnosed with ALS at age 22, he went on to unravel the mysteries of black holes and popularize cosmology among the general public for over 50 years.
May 7, 2018 · Stephen’s PhD advisor Dennis Sciama started him working on cosmology. An important question in the 1960s was, “Did the universe have a beginning?” Observations and the Einstein equation suggested that the early universe was very hot.

What made Hawking such a trailblazer were his attempts to merge quantum physics and general relativity. The situation in modern physics is both powerful and dire. We have two incredibly strong theories that have passed every test we can throw at them, and yet we can't unify them. General relativity is our theory of gravity, with thanks to Einstein,...
Hawking famously describedthe quest for a theory of everything in analogy to God: "If we do discover a theory of everything… it would be the ultimate triumph of human reason—for then we would truly know the mind of God." He was forced to explain this line many times. As a devout atheist he made it clear that he didn't mean we would understand a dei...
We know that nothing, not even light, can escape a black hole's gravitational pull. Nevertheless, Hawking discovered that black holes should "glow". The light they emit is now known as "Hawking radiation". But if light can't escape from black holes, how can they glow? The event horizon of a black hole is the point of no return. Once you are within ...
Hawking became one of the world's most recognisable physicists. His fame saw him appear frequently in popular culture including on the Simpsons and Star Trek (where he played himself). Not only a superb researcher, he was a brilliant communicator, and this set him apart from his peers. His A Brief History of Timesold more than 10 million copies and...
That Hawking survived until age 76 is truly remarkable. Diagnosed with amyotrophic lateral sclerosis(ALS) as a 22 year old, he was given only two years to live. Rather than being defeated by such a diagnosis he dove into research with an urgency perhaps inspired by his limited time. He determined to do something significant with his time remaining,...
Mar 14, 2018 · Hawking continued to seek new links between the very large (the cosmos) and the very small (atoms and quantum theory) and to gain deeper insights into the very beginning of our universe ...
Mar 14, 2018 · Hawking began sharing his vision of the universe in 1966 while studying physics at the University of Cambridge, when he turned in a doctoral thesis on the origin of the universe. At the time,...
He pioneered the study of primordial black holes and their potential role in cosmology. His organization of and contributions to the Nuffield Workshop in 1982 consolidated the picture that the large-scale structure of the universe originated as quantum fluctuations during the inflationary era.
