- Experimental quest to test Einstein's speed limit
( University of California - Berkeley ) Special relativity states that the speed of light is the same in all frames of reference and that nothing can exceed that limit. UC Berkeley physicists used a novel experimental system -- the unusual electron orbitals of dysprosium -- to test whether the maximum speed of electrons follows this rule. The answer is yes, to tighter limits than ever before ...
