Sentences with phrase «information out of a black hole»

The weirdness of quantum teleportation offers a solution for getting information out of a black hole, should you have dropped something in there

Not exact matches

Likewise, if black holes act like information mirrors, as Hayden and Preskill suggested, a particle falling into a black hole would be followed by an antiparticle coming out — a partner with the opposite electric charge — which would carry the information contained in the spin of the original particle.
One theorist who requested anonymity out of respect for Hawking says his various solutions for the black hole information problem pale next to his best work.
Hawking spent much of his later years trying to figure out how a black hole could regurgitate information — although he also worked on theories of what triggered the big bang.
The information would basically remain encoded in an infinite number of low - energy photons racing to get out of the black hole, but stuck at its event horizon by the black hole's intense gravity, according to a study in Physical Review Letters.
Carroll agrees, but hopes their work «starts us thinking in slightly different ways about what it would mean to get qubits out [of a black hole]», and thus solve the puzzle about what happens to the information that falls into a black hole.
By taking the change in the black hole's spin, and her half of the Hawking radiation that is emitted after she drops the qubit, Alice can use the rules of quantum teleportation to work out the spin of the qubit she dropped into the black hole — and hence retrieve information from beyond the black hole's event horizon.
Nearly all of the information that falls into a black hole escapes back out, a controversial new study argues.
Chatwin - Davies and colleagues realized that they could teleport the information about the state of an electron out of a black hole, too.
The calculation touches on one of the biggest mysteries in physics: how all of the information trapped in a black hole leaks out as the black hole «evaporates.»
When the black hole evaporates and disappears, it has already preserved the information of everything that fell into it, radiating it out into the universe.
Picking out twisted photons from a black hole would provide new information about the objects themselves and provide important tests of general relativity, says Martin Bojowald, a theoretical physicist at Pennsylvania State University who wrote a commentary on Thidé and his colleagues» work for Nature Physics.
But this conflicted with the laws of quantum physics, which state that information about what fell into the black hole can never be completely wiped out.
For example, if a black hole is modelled according to string theory — in which the universe is made of tiny, vibrating strings rather than point - like particles — there are pretty convincing arguments that say information can get out, according to Joseph Polchinski from the University of California in Santa Barbara, US.
Physicists believe that information about the contents of a black hole radiates out from its surface in the form of Hawking radiation.
