PARIS  -- A comet or asteroid smashed into modern-day Germany some 2,200 years ago, unleashing energy equivalent to thousands of atomic bombs, scientists revealed.     The 1.1-kilometre (0.7-mile) diameter rock wacked into southeastern Bavaria, leaving an "exceptional field" of meteorites and impact craters that stretch from the town of Altoetting to an area around Lake Chiemsee, the scientists said Friday in an article in the latest issue of US magazine Astronomy...
