That's what a Hawaii man with a background in nuclear physics is asking a court to do.
Walter F. Wagner and his colleague Luis Sancho have filed a federal lawsuit seeking to stop work on the Large Hadron Collider, a gigantic atom smasher on the Franco-Swiss border that's set to start operations in May.
The plaintiffs' concerns? That the LHC could accidentally create strange new particles that would instantly transform any matter they touched, engulfing the Earth, or, even worse, make a rapidly expanding black hole that could consume the entire planet.
"[T]he compression of the two atoms colliding together at nearly light speed will cause an irreversible implosion, forming a miniature version of a giant black hole," reads the lawsuit, filed in U.S. District Court in Honolulu.
