Although there are currently said to be more than 14 billion pages on the Internet, a new study shows that navigation between any two of these pages should take you no more than 19 clicks — that’s how interrelated everything is. The study was published in Philosophical Transactions of the Royal Society and conducted by Albert-Laszlo Barabasi of Northeastern University’s Center for Complex Network Research in Boston.

Barabasi, a leader in network research, says that the 19 clicks of separation have to do with human nature, according to Smithsonian magazine. It works because Internet pages are organized in an interconnected hierarchy of organizational themes, including region, country and subject area.
