The scientists sued the European Center for Nuclear Research to block the $8 billion advanced physics research facility.
In a lawsuit filed in Honolulu, they claim the accelerator could not only create a black hole that would eat the Earth, but could also emit a "strangelet" that would convert the planet to a shrunken dense dead lump of quasi-matter.
The lawsuit also complains that the Center failed to file an environmental impact statement.
A spokesman for the Center said the lawsuit was flawed because the organization isn’t subject to jurisdiction in Hawaii.
