The speed of light has a potential race spoiler and Einsteins theory* of special relativity might eventually have to be bumped after a reign of more than century.
*For the maroons out there: in the realms of science a "theory" is a concept that has been accepted as true by the scientific community, having been tested and/or observed repeatedly and rationally shown to be so; usually with a null hypothesis getting a mighty good work out along the way. A theory, then, should not be confused with a hypothesis or a happy consensus amongst the government-funding-reliant.
Laws of physics challenged
The Super-Kamiokande neutrino observatory uses 50,000 tons of pure water surrounded by 11,200 sensitive light detectors 1 kilometer below ground in Japan. Neutrinos from space interact with the water and produce flashes of blue light.
In 1930, Wolfgang Pauli first conceived of neutrinos—originally as a solution to a problem in nuclear physics. Neutrinos are so elusive that it would be 26 years before they were actually detected.
