Hawking conceded when sufficiently convincing mathematics showed that the information in the enclopedia would reemerge as patterns in so - called
Hawking radiation emitted by the blackhole.
The most advanced civilizations will be reduced to huddling around the last flickering embers of energy — the faint
Hawking radiation emitted by black holes.
Unlike the subatomic crack - ups in particle accelerators, where the colliding particles fragment directly into their components, nothing that falls into a black hole — gas, stars, people — has a direct connection to
the Hawking radiation it emits in the present.

«I think most physicists would agree that
Hawking's greatest contribution is the prediction that black holes
emit radiation,» says Sean Carroll, a theoretical physicist at the California Institute of Technology.
But in 1975, together with the Israeli physicist Jakob Bekenstein,
Hawking showed that black holes slowly
emit radiation, causing them to evaporate and eventually disappear.
Upon
Hawking's death on March 14 at age 76, his most famous discovery — that black holes aren't entirely black, but
emit faint
radiation — was still fueling debate.
It all began in the mid-1970s, when Stephen
Hawking of the University of Cambridge showed theoretically that black holes are not truly black, but
emit radiation.
STEPHEN
HAWKING famously predicted that black holes would «evaporate» away over time,
emitting a form of
radiation and slowly losing mass until they vanish.
His new theory is that
Hawking radiation can pick up some of the information stored on the event horizon as it is
emitted, providing a way for it to get out.
In the 1970s
Hawking introduced the concept of
Hawking radiation — photons
emitted by black holes due to quantum fluctuations.
Physicist Stephen
Hawking determined in 1974 that black holes slowly evaporate over time,
emitting what's known as
Hawking radiation before eventually disappearing.
Instead, they
emit a faint haze of particles, known as
Hawking radiation (SN: 5/31/14, p. 16).
A model black hole that traps sound instead of light has been caught
emitting quantum particles - it could be the first time theoretical
Hawking radiation has been seen
Hawking radiation, the result of attempts to combine quantum theory with general relativity, comprises these escaping particles, but physicists have yet to detect it being
emitted from an astrophysical black hole.
Since the discovery of
Hawking radiation, physicists have thought that
radiation would be
emitted randomly, thus destroying any information encoded in anything that had fallen into the black hole — which, perplexingly, would violate a basic tenant of quantum mechanics.
Physicists fired polarized laser pulses at a block of glass, creating distortions that
emitted Hawking radiation out the sides of the block (inset).
Like turning the knob on a radio, the team adjusted the pulse so that, if the artificial horizon
emitted any
Hawking radiation, its wavelength would be between 800 and 900 nanometers, a range that could not be confused with other sources such as laser - induced fluorescence.
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.
Crucially, since the artificial horizon can only trap photons in a certain range of wavelengths, it can only
emit Hawking radiation in that range.
Scientists have come closer than ever before to creating a laboratory - scale imitation of a black hole that
emits Hawking radiation, the particles predicted to escape black holes due to quantum mechanical effects.
The Unruh effect is closely related to
Hawking radiation, extremely faint
radiation emitted by a black hole at a temperature determined by its mass.
But in the 1970s, Stephen
Hawking used quantum mechanics to show black holes do
emit radiation, which eventually evaporates them away completely.
Trouble began brewing in the 1970s when
Hawking mixed quantum mechanics into relativistic black hole theory and concluded that they should
emit a tiny amount of
radiation, which steals mass until the black hole evaporates.
The discovery could potentially provide a way to test Stephen
Hawking's prediction that a real black hole should slowly evaporate as it
emits radiation generated in the quantum turmoil at its event horizon.
He proved that black holes actually
emit a stream of what is now called
Hawking radiation.
Although not even light can escape their gravity,
Hawking calculated that black holes should nonetheless
emit a faint glow, now called
Hawking radiation.
But Stephen
Hawking showed in 1976 that black holes should in fact
emit radiation due to the effects of quantum mechanics, and will eventually evaporate away.
In the mid-1970s,
Hawking discovered that black holes are not truly black, and in fact
emit some
radiation.
