In this video, we explore the groundbreaking work of physicist Stephen Hawking and his contributions to our understanding of the universe. From his early wor...
May 2, 2023 · Hawking continued to explore the fundamental nature of the universe until his death in 2018. In a new book, On The Origin of Time, Belgian physicist Thomas Hertog unravels Hawking’s final theory ...
Mar 14, 2018 · Although my body is very limited, my mind is free to explore the universe, to go back to the beginning of time and into black holes. There are no limits to the human spirit. Hawking first gained ...

It's only fitting that Professor Hawking's first big discovery addressed the very first moments of the universe. The big bang theory — that the universe started as a minuscule dot that expanded (and is still expanding) — is widely accepted today. But in the 1960s that wasn't the case. As a young researcher at Cambridge, Professor Hawking started th...
Most of Professor Hawking's work, though, applies to black holes: a patch of space where gravity is so intense that nothing — not even light — can escape. A black hole's event horizon is the boundary where a particle would have to travel faster than the speed of light to escape. But what if black holes emitted a bit of radiation? Enter quantum theo...
Never afraid of a bold idea, Professor Hawking proposed in a 2014 paperthat instead of having an event horizon, a black hole is surrounded by an "apparent horizon". Rather than blocking absolutely everything from escaping, an apparent horizon would hold energy and matter temporarily before spitting it back out into space (but jumbled up). He conclu...
What happens to all the physical "information" swallowed by a black hole? General relativity states that it should be destroyed, but quantum mechanics says the opposite. Professor Hawking dealt with this corker of a question in 2015. His idea was that information, once it passes the event horizon, doesn't actually make it all the way inside a black...
Finally, a special shout-out goes to an experiment that exemplified Professor Hawking's knack for showmanship. On June 28, 2009, he threw a party for time travellers. Surrounded by bottles of champagne and plates of hors d'oeuvres, Professor Hawking waited … and waited … but no-one showed up. In his television series, he said: "I have experimental ...

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.
