What is the solution to the black hole information paradox?

In summary, the conversation discussed the concept of "hair" in relation to black holes. The no hair theorem states that black holes only possess three properties - mass, electric charge, and angular momentum. However, this violates the principle of quantum physics that information cannot be destroyed. Steven Hawking proposed that black holes may have "hair" that stores information, but this has yet to be proven. The paper "Soft Hair on Black Holes" has sparked recent interest in finding a solution to the black hole information paradox.

The only info, according to the no-hair theorem, that we can get from a Black Hole is only about its mass, electric charge and angular momentum because all other info (which was called hair) gets lost behind the event horizon.
Steven Hawking stated that black holes do have hair and he proposed that at least some of the information devoured by a black hole is stored in "hair".

The 'hair' of a black hole relates to the notion that a black hole has only three properties - mass, charge and angular momentum. This is commonly referred to as the no hair theorem formulated by John Wheeler [who blamed it on Jacob Bekenstein]. In quantum physics, this violates the principle that quantum information must cannot be destroyed. However, information, as defined under quantum physics cannot be encoded using only these three parameters, thus leading to the black hole information paradox. The only apparent solution to this paradox is either that quantum information can be encoded using only mass, charge and spin, or, that black holes have other definable properties. Physicists have argued the 'information paradox' for decades, but, an entirely satisfactory resolution has proven elusive. An attempt offered by this paper: http://arxiv.org/abs/1601.00921, Soft Hair on Black Holes. has been a hot topic in the physics community lately.

1. What is a hairy black hole?

A hairy black hole is a theoretical concept in astrophysics where a black hole is surrounded by a field or structure that extends beyond its event horizon. This field or structure is called "hair" because it changes the appearance of the black hole and affects its behavior.

2. How does hair affect a black hole?

Hair has a significant impact on a black hole's properties, such as its mass, spin, and gravitational pull. It can also affect the way black holes interact with matter and other objects in their vicinity.

3. What are some examples of hairy black holes?

Some proposed examples of hairy black holes include Kerr-Newman black holes, which have both electric and magnetic fields, and gravastars, which are hypothetical objects with a shell of matter surrounding a central singularity.

4. How do scientists study hairy black holes?

Scientists use computer simulations and mathematical models to study hairy black holes. They also observe the effects of these structures on their surroundings, such as the distortion of light and matter.

5. Can hairy black holes exist in our universe?

While there is no conclusive evidence for the existence of hairy black holes in our universe, some theories and models suggest that they may be possible. However, more research and observations are needed to confirm their existence.
