CAMBRIDGE, Mass., Aug. 28 (UPI) – Entangled white dwarf stars have proved Einstein’s theory that moving objects create subtle ripples in the fabric of space-time, U.S. astronomers say.
Einstein’s theory of general relativity predicts moving objects create the ripples, called gravitational waves, and astronomers have used a pair of white dwarf stars so close together they make a complete orbit in less than 13 minutes to confirm it, a release from the Harvard-Smithsonian Center for Astrophysics reported Tuesday.
