Mar 15, 2018 · Hawking worked out this idea in 1974, which is why this hypothesized black-hole light is known as Hawking radiation, or Hawking-Bekenstein radiation. Nobody has spotted such emissions...

While in Schwarzschild's formulation, black holes were static objects, Hawking was the first to prove that it isn't so. Black holes radiate over time, and as such, aren't...

In 1974, Hawking published a paper that contained one of the strangest ideas yet about black holes. At the time, the consensus among physicists was that once something gets sucked into a black hole it can never escape. They believed that as black holes kept swallowing up all matter around them, they grew inexorably. Hawking showed that black holes ...
For all Hawking’s remarkable insights, he was never able to solve one of the greatest puzzles involving black holes. Every star is associated with lots of information — ranging from its shape and chemical composition to how fast it spins. But when a star collapses to become a black hole, it seems that all that information is lost forever. But this ...
Hawking himself might not have been surprised should the real answer to the information paradox be far stranger. In one of his final published works, Hawking argued that black holes might serve as gateways to parallel universesand that missing information might actually be transferred to those universes. Whatever the truth, Hawking remained convinc...

Mar 14, 2018 · In the 70s, Hawking considered whether the particles and light entering a black hole were destroyed if the black hole evaporated. Hawking initially thought this "information" was lost from the ...
Jul 1, 2021 · In 1971, Stephen Hawking proposed the area theorem, which set off a series of fundamental insights about black hole mechanics. The theorem predicts that the total area of a black hole’s event horizon — and all black holes in the universe, for that matter — should never decrease.
Mar 14, 2018 · At their very fringes, Hawking demonstrated, black holes would create and radiate new particles due to these laws, losing energy, and hence losing mass (remember Einstein's equation E=mc²).
