Physicist Stephen Hawking determined in 1974 that black holes slowly evaporate over time, emitting what's known as Hawking radiation before eventually disappearing.

The smallest black holes would have evaporated through a process called Hawking radiation long ago, and the largest would be detectable by the way their gravity bends the light of background objects.

Hawking showed in the 1970s that every black hole will eventually evaporate and disappear, potentially destroying all the information the object once contained about how it formed and evolved over time.

Four decades after surprising the physics world by showing that black holes might generate radiation and evaporate, Stephen Hawking has now published research describing how information might survive to escape from such an astronomical sink hole, too, The New York Times reports.

Some of the most exotic objects in physics, such as evaporating black holes, cosmic strings and even possible extra dimensions, would induce gravitational waves at much higher frequencies than we can currently detect.

If you have something that implodes to make a black hole, which then completely evaporates due to Hawking radiation, does all the information that went into the black hole come back out?

We will see mini-black holes only if our universe has higher dimensions, and then only if they form and evaporate through what's called Hawking radiation [a kind of radiation that is hypothesized to escape right along the horizon of a black hole].

One alternative, that evaporating black holes leave behind remnants, is equally unpalatable.

That process, now known as Hawking radiation, explains why we do not have to fear any mini black holes created by the Large Hadron Collider; they would «evaporate» into radiation almost instantly.

The total time for a black hole to evaporate away is proportional to the cube of its initial mass.

Because of this effect, dubbed Hawking radiation, a black hole slowly evaporates, so that anything that enters is eventually released over billions or even trillions of years.

But in the 1970s, Stephen Hawking used quantum mechanics to show black holes do emit radiation, which eventually evaporates them away completely.

The black holes found in the universe are so cold that it takes forever for them to evaporate, many orders of magnitude longer than the age of the universe.

«Passengers on a spaceship would like some guarantee that when they fall into this black hole and get smooshed into the singularity, they can be recreated as it evaporates,» Lloyd told New Scientist.

These black holes would evaporate almost instantaneously, without moving by more than the size of the atomic nucleus.

If so, it might mean the black holes are evaporating into extra dimensions.

In 1975 Stephen Hawking at the University of Cambridge calculated that black holes would slowly but inexorably evaporate.

But even if evaporating black holes were abundant enough in the early universe, the reduction of the dark matter in PBHs could be compensated by an increase of radiation.
