It has been recently announced that the complicated existence of Gravitational Waves has been proven with the announcement made with the findings with the special facilities dedicated in measuring distortion in space-time.
The scientists at Laser Interferometer Gravitational-wave Observatory, or LIGO has recorded the distortion by this special instrument back in September 14, 2015 which spans kilometers long and uses "pure light" to detect the passing of unstoppable yet feeble force which is smaller than a proton. They made the instrument so big, so that the small changes would be detected. The gravitational wave detected is believed came from two black holes merging into one while giving out a rippling effect that dates back to billions of years ago.
