An American living in Hawaii has sued the European nuclear laboratory CERN for its Large Hadron Collider that is going into service soon, starting accelerations in June 2008. CERN has been sued at a district court in Hawaii by a botanist (who is also lawyer and had been one time nuclear safety officer) and a self described "author and researcher on time theory".
The two fear that it will create black holes that are going to eat up the entire earth and maybe even more.
The US is no member of CERN even though American companies and scientists are working with CERN as well.
