A different type of detector just ungraded is rumored to have found the waves. It is the LIGO which detects a slight difference in time between two observant stations in Washington and Louisiana, as a wave passes:-https://en.wikipedia.org/wiki/LIGO-"LIGO operates two gravitational wave observatories in unison: the LIGO Livingston Observatory in Livingston, Louisiana, and the LIGO Hanford Observatory, on the DOE Hanford Site , located near Richland, Washington. These sites are separated by 3,002 kilometers (1,865 miles). Since gravitational waves are expected to travel at the speed of light, this distance corresponds to a difference in gravitational wave arrival times of up to ten milliseconds. Through the use of triangulation, the difference in arrival times can determine the source of the wave."-The rumors from two sources, among others:-https://www.washingtonpost.com/news/speaking-of-science/wp/2016/01/12/why-is-this-famous-physicist-tweeting-rumors-about-gravitational-waves/?wpmm=1&wpisrc=nl_evening-"The first thing you should know about this rumor is that it's from a pretty believable source: Lawrence Krauss is an award-winning physicist and a respected science communicator and advocate. Krauss actually started the rumor back in September, but confirmed it on Monday."-http://www.theguardian.com/science/2016/jan/12/gravitation-waves-signal-rumoured-science-"According to the rumours, scientists on the team are in the process of writing up a paper that describes a gravitational wave signal. If such a signal exists and is verified, it would confirm one of the most dramatic predictions of Albert Einstein's century-old theory of general relativity."-Comment: Wow, maybe!
