Bizarre binary star system pushes study of relativity to new limits
Toronto, Canada (SPX) Apr 29, 2013
An international team of astronomers and an exotic pair of binary stars have proved that Albert Einstein's theory of relativity is still right, even in the most extreme conditions tested yet. The results of their research are described in the April 26 issue of Science. "The unusual pair of stars is quite interesting in its own right but we've learned it is also a unique laboratory for testing the limits of one of our most fundamental physical theories, general relativity" says University of Toront ... read more
