The Thorne–Hawking–Preskill bet was a public bet on the outcome of the black hole information paradox made in 1997 by physics theorists Kip Thorne and Stephen Hawking on the one side, and John Preskill on the other, according to the document they signed 6 February 1997, [1] as shown in Hawking's 2001 book The Universe in a Nutshell.
Supermassive black holes, regions of space where the pull of gravity is so intense that even light doesn't have enough energy to escape, are often considered terrors of the known universe.
This is because the analysis concludes that supermassive black holes are the largest contributor. [33] Lee Smolin goes further: "It has long been known that gravity is important for keeping the universe out of thermal equilibrium. Gravitationally bound systems have negative specific heat—that is, the velocities of their components increase ...
A black hole with the mass of a car would have a diameter of about 10 −24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more than 200 times that of the Sun. Lower-mass black holes are expected to evaporate even faster; for example, a black hole of mass 1 TeV/c 2 would take less than 10 −88 ...
The deviled eggs and beans chemically conspired in my belly to convert my digestive tract into a clandestine, invisible, and silent chemical weapons program. That was more than 20 years ago. I ...
Here, millions of people come together to share the most surprising, obscure, and fascinating facts they’ve just discovered. Some change how we see the world, while others are simply ...
Suppose two black holes have the same masses, electrical charges, and angular momenta, but the first black hole was made by collapsing ordinary matter whereas the second was made out of antimatter; nevertheless, then the conjecture states they will be completely indistinguishable to an observer outside the event horizon.
