\n\tGravitational waves were first directly detected two years ago, proving Albert Einstein’s theory of general relativity, and recently, three scientists were awarded the Nobel Prize in Physics for their work on that first detection. Those gravitational waves were the result of two black holes colliding, and the signal lasted for only a fraction of a second. Because black holes don’t emit light, these waves were invisible and only “heard” as thumps.<\/span>\n<\/p>\n
