Michelson–Morley experiment is best yet

Physicists in Germany have performed the most precise Michelson-Morley experiment to date,

The experiment, which involves rotating two optical cavities, is about 10 times more precise than previous experiments – and a hundred million times more precise than Michelson and Morley's 1887 measurement.
