I just read about this thing from a magazine and thought I'd share it with you.

In Princeton University they are seriously researching such thing as "The Global Consciousness". The scientists believe that people can affect to computers and everything with plain brain waves. They have set up a network of Random Event Generators all over the world, which then connects to their university via the Internet. REGs create 0's and 1's randomly, but - here's the point - the general mood of people can affect to the numbers being generated.

They say that they have seen big events like the WTC and Olympic Games as peaks in the graphs. JFK Junior getting killed almost only caused a peak in the US graph and so on.
They don't even claim that they can explain the true nature of the phenomena, but they say it exists. The homepage of the project is very wide and explains things nicely, so please check it out before replying.

A quote from the project main page:
The Global Consciousness Project (GCP) is an international effort involving researchers from several institutions and countries, designed to explore whether the construct of interconnected consciousness can be scientifically validated through objective measurement. The project builds on excellent experiments conducted over the past 35 years at a number of laboratories, demonstrating that human consciousness interacts with random event generators (REGs), apparently "causing" them to produce non-random patterns. A description of the technical implementation is given under procedures.
