Fuzzballs
From Wikipedia, the free encyclopedia
Fuzzballs, also called Stringy Stars, are String Theory's equivalent of black holes. In recent years physicists have delved into how strings could interconnect to create black holes; the result are large, very flaccid discs, which would not have a point sized singularity that is the essence of the modern black hole.

[edit] The event horizon
Samir Mathur of Ohio State University calculated that the event horizon of a fuzzball agrees with the current theory of black holes, but in one way it is different. The event horizon of a black hole is very precise and strict while in a fuzzball the event horizon is very much like a mist; it is fuzzy, hence the name 'fuzzball'.
[edit] The essence of the black hole
Black holes have grabbed attention as the massive killers of the universe that destroy anything in their path - even light cannot escape their pull. However fuzzballs have redefined this idea. As described earlier a fuzzball doesn't have a prominent singularity at its centre, and so the destruction of data that is the essence of a black hole no longer exists in a fuzzball. Instead the data from the fuzzball marks the strings that carry the information in vibrations. This data can be given out by the escape of Hawking radiation.
[edit] The information paradox
Black holes create a problem; they cause a contradiction widely known as the black hole information paradox, which means that they don't obey the laws of quantum physics. The problem is that it is widely believed particles that enter a black hole release no information outside of the black hole. However, fuzzballs may solve this problem by the fact that information that enters a fuzzball is given out by the vibrations in the strings that make them up.
[edit] More on Fuzzballs
Fuzzballs are also small yellow balls of fuzz with orange feet that you can buy at http://www.fuzzballfamily.com . The site sells fuzzball stuffies and pendants, of which all funds are donated to the Red Cross for those in need.
