NEW YORK — Scientists have observed for the first time the faint ripples caused by the motion of black holes that are gently stretching and squeezing everything in the universe. They reported Wednesday that they were able to “hear” what are called low-frequency gravitational waves — changes in the fabric of the universe that are created by huge objects moving …
Scientists may have, for the first time, heard the gravitational wave background or resonant ‘hum’ that permeates the Universe for the very first time. Researchers studying the signals from distant pulsars, made use of radio telescopes to collect statistics that may indicate the effects of gravitational waves. According to study authors, the low-frequency signal may be attributable to gravitational waves. …
