Scientists defy Einstein's prediction and use relativity to measure a star's mass

in #science8 years ago

Astronomers scanning the skies with NASA’s Hubble Space Telescope have pulled off a feat that even Albert Einstein had declared all but impossible: they’ve witnessed the subtle bending of one star’s light by another star’s gravity and used that distortion to measure a star’s mass.The findings, unveiled Wednesday at a meeting of the American Astronomical Society and published in the journal Science, confirm a key tenet of Einstein’s landmark general theory of relativity and introduce a new tool with which to explore a fundamental property of stars.  The findings, unveiled Wednesday at a meeting of the American Astronomical Society and published in the journal Science, confirm a key tenet of Einstein’s landmark general theory of relativity and introduce a new tool with which to explore a fundamental property of stars.
