Fourth gravitational wave signal detected – Five things you need to know

Fourth gravitational wave signal detected – Five things you need to know The latest observation was made on August 14, 2017. It’s the first gravitational wave signal recorded by the Virgo detector. New Delhi: Originally predicted in the early 20th century by Albert Einstein, gravitational waves – ripples in space and time – were not detected until 2015, when the Laser Interferometer Gravitational-wave Observatory (LIGO) identified the first such signal from two merging black holes. On Wednesday, scientists announced the detection of a fourth gravitational wave signal coming as a…

Kip Thorne co-writer of Nolan’s Interstellar, awarded Nobel Prize for Physics

Kip Thorne co-writer of Nolan's Interstellar, awarded Nobel Prize for Physics

Kip Thorne co-writer of Nolan’s Interstellar, awarded Nobel Prize for Physics Kip Thorne : Oscar Awards snubbed science epic Interstellar and its co-writer Thorne. Nobel committee knows better than that. New Delhi: What has one of this year’s Nobel Prize winning physicist to do with making a Hollywood film a blockbuster? A lot, if you ask. While Oscars gave a royal snub to the writers and creators of Interstellar, Nobel Prize committee know better than. Before this Tuesday, Kip S Thorne, the 77-year-old American theoretical physicist whose work on gravitational…

LIGO snags another set of gravitational waves

LIGO snags another set of gravitational waves

LIGO snags another set of gravitational waves Spacetime vibrations arrive from black hole collision 3 billion light-years away For a third time, scientists have detected the infinitesimal reverberations of spacetime: gravitational waves. Two black holes stirred up the spacetime wiggles, orbiting one another and spiraling inward until they fused into one jumbo black hole with a mass about 49 times that of the sun. Ripples from that union, which took place about 3 billion light-years from Earth, zoomed across the cosmos at the speed of light, eventually reaching the Advanced…
