It used to be that we were all just six degrees of separation apart - ie you could 'connect' anyone to anyone else via finding a friend who knew someone else, who knew someone else, and so on.
But now research by Facebook has found that the gap between us all has shrunk - to as little as four people. The average person needs just 4.74 ‘hops’ to get to anybody in the world, be it a Hollywood star or a peasant living in rural China.
Degrees of separation: From Charlotte Church to Kim Jong-Il in just five step
The figure has gone down from 5.28 in 2008 and has been caused by the rise in social networking and sharing websites. The startling figure shows how interconnected our world is becoming and how widespread use of the internet is collapsing physical distance on an unprecedented scale.
No longer are we six degrees of separation apart - Earth is much smaller now than it used to be.
Facebook worked with researchers at the Università degli Studi di Milano in Italy and looked at all 721million of its active users, equivalent to 10 per cent of the world’s population and a total of 69billion friendships. In the largest study of its kind ever undertaken, they found that as Facebook has grown the average distance between users has shrunk to 4.74 hops, but in some places it is even less.
