Scientists from the ISA/Munchen (Germany) have published a report which confirms that planet Earth could be driven out of its current orbital rotation by the combined force of human beings jumping. Prof. Hans Niesward and his colleagues at the Department of Gravitationasphysik estimated that it would take a minimum of 600 Million people on the western hemisphere to jump at the same moment.

The scientists incorporated a variety of siesmographic recordings ranging from the impacts of comets (comet "Joulios hitting the surface of the Pacific Ocean, 03 21 2001) to the simultaneous movement of the audience at the 2002 soccer World Cup Final.
