How is the black hole information paradox resolved?

How is the black hole information paradox resolved?

In July 2004, Stephen Hawking published a paper presenting a theory that quantum perturbations of the event horizon could allow information to escape from a black hole, which would resolve the information paradox.

What happens if a black hole and a white hole collide?

Although it was able to defend itself against everything else in the Universe, unfortunately, the black hole is its one true match. So if a white hole and black hole collided, we’d have a massive black hole roaming around the Universe, destroying everything in its path.

Does information escape a black hole?

Hawking had tried to apply quantum mechanics to particles near a black hole’s periphery, and saw unitarity break down. 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.

What is the connection between black hole and white hole?

The negative square root solution inside the horizon represents a white hole. A white hole is a black hole running backwards in time. Just as black holes swallow things irretrievably, so also do white holes spit them out. White holes cannot exist, since they violate the second law of thermodynamics.

Is information paradox solved?

No, Stephen Hawking’s Black Hole Information Paradox Hasn’t Been Solved. But outside the event horizon, the black hole is predicted to emit radiation. Hawking’s 1974 work was the first to demonstrate this, but that work has also led to a paradox that has not yet been resolved.

Is there a white hole in space?

White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes. While a black hole’s event horizon is a sphere of no return, a white hole’s event horizon is a boundary of no admission — space-time’s most exclusive club.

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.

What happens if you go into a white hole?

No spacecraft will ever reach the region’s edge. Objects inside a white hole can leave and interact with the outside world, but since nothing can get in, the interior is cut off cut off from the universe’s past: No outside event will ever affect the inside.
