In 1968, scientists thought they were close to detecting gravity waves

In 1968, scientists thought they were close to detecting gravity waves WAVE RUNNER Joseph Weber (shown in 1969) announced he detected a gravity wave using his aluminum cylinder detector at University of Maryland in College Park. It took nearly five decades for LIGO to confirm that gravity waves can be detected. Gravity waves evidence The long search for gravitational waves … may be in the final lap…. Rotating binary stars or, perhaps, other galaxies like the Milky Way but far beyond it, or the center of the Milky Way itself, are likely sources for gravitational radiation. — Science News, June 22, 1968. Update Although Joseph Weber, a physicist at the University of Maryland, announced a gravity wave detection in 1969, no one could verify his claim. It took almost another 50 years for researchers to directly detect gravitational waves (SN: 3/5/16, p. 24). Those spacetime ripples from two merging black holes, glimpsed by the Advanced Laser Interferometer Gravitatio...

Cambridge IGCSE Cambridge IGCSE is the world’s most popular international qualification for 14 to 16 year olds. It is recognised by leading universities and employers worldwide, and is an international passport to progression and success. Developed over 25 years ago, it is tried, tested and trusted by schools worldwide. I was stuck with past paper for A level , then I found an application for my phone where I can find past paper, video, professor notes and online text as well all things are free. It changed my way of study… U guys also can use this application. I am giving link below. https://play.google.com/store/apps/details?id=a.shapefuture
