By Justin Mullins AN ACCIDENTAL explosion in a German physics lab has led to the identification of a superpowerful explosive. The substance—an exotic form of silicon—releases seven times as much energy as TNT, and explodes a million times faster. “This might be the strongest explosive ever discovered,” says Dmitri Kovalev, the physicist who runs the laboratory at the Technical University of Munich in Garching. Kovalev and his team were studying the optical properties of porous silicon, a sponge-like material. The group had cooled the silicon in a vacuum to the temperature of liquid nitrogen,
