Gravity Waves Hat

For over a billion years, a particular set of gravity waves which originated when two black holes coalesced, have been travelling through space. Nearly a billion years later, Einstein, through precise Mathematics, creative intuition and his sheer genius predicts that such waves would exist. Nearly 100 years later, those waves were detected in what might as well be the most precise measurement made by humankind. That’s how smart Einstein was and that’s how awesome Science is.
