Is the black hole paradox solved?
Researchers may have solved Professor Stephen Hawking's famous black hole paradox—a mystery that has puzzled scientists for almost half a century. According to two new studies, something called "quantum hair" is the answer to the problem.
How is the black hole information paradox solved?
Stephen Hawking's black hole information paradox has bedevilled scientists for half a century and led some to question the fundamental laws of physics. Now scientists say they may have resolved the infamous problem by showing that black holes have a property known as “quantum hair”.
Has the black hole information paradox evaporated?
Since the black hole never evaporates, information about its initial state can remain inside the black hole and the paradox disappears. However, there is no accepted mechanism that would allow Hawking radiation to stop while the black hole remains macroscopic.
Can information escape a black hole?
One of the leading researchers is Netta Engelhardt, a 32-year-old theoretical physicist at the Massachusetts Institute of Technology. She and her colleagues have completed a new calculation that corrects Hawking's 1974 formula; theirs indicates that information does, in fact, escape black holes via their radiation.
Is Hawking radiation proven?
Hawking radiation has never been observed, but if it exists the information lost when objects enter a black hole might be carried out of the black hole via this light. Thus the information isn't truly lost.
Can a quasar escape a black hole?
Answer and Explanation: No, a superheated quasar cannot escape a black hole once it crosses the all important Schwarzschild radius, the point at which it is not possible for…
Is information lost?
Thus, information is never lost. This has implications in black hole information paradox and in fact any process that tends to lose information completely. The no-hiding theorem is robust to imperfection in the physical process that seemingly destroys the original information.
Is Hawking radiation disproved?
Hawking radiation has never been observed, but if it exists the information lost when objects enter a black hole might be carried out of the black hole via this light. Thus the information isn't truly lost. If Hawking radiation is real, that also means that black holes follow the laws of thermodynamics.
Does Hawking radiation solve information paradox?
Instead, most physicists try to solve the paradox by finding some way — any way — for the information inside the black hole to leak out through the Hawking radiation. That way, when the black hole disappears, the information is still present in the universe.
