Report: There is only four degree of separation between two people



A study done by Facebook aka, “The Anatomy of Facebook”  have found some interesting results of the sepration of two peoples. By some of the graph theory we can say that there is only certain edges connecting  any two peoples of  the world. [WHERE EDGES REPRESENTS CONNECTION BETWEEN FRIENDS].

In 1967 an experiment(small world experiment) done by “While Stanley Milgram” which was drew on 296 voluenteers and pegged the average number of people seprating two individuals are over 5.2 peoples or 6 hops.

Now an recent experiment was done over 721 million active Facebook users shows the number of separation is even less than 5.2 . In a note it states:

We found that six degrees actually overstates the number of links between typical pairs of users: While 99.6% of all pairs of users are connected by paths with 5 degrees (6 hops), 92% are connected by only four degrees (5 hops).

This means  that no two peoples are seperated by more than 4 intermediates connections.  It have also found that in a same country the world is even smaller.The seperation of degree is found to be only 3 connections.
This research was concluded in november of this year. In 2008 the average number of connection was found to be 5.28 hops but now it is reduced to only 4.74 hops.

The idea of “Six degrees of seperation” was proposed on 1929  by Hungarian author Frigyes Karinthy, and made popular by the John Guare play and movie, Six Degrees of Separation.
