"For the first time, scientists have witnessed the cataclysmic crash of two ultra-dense neutron stars in a galaxy far away, and concluded that such impacts forged at least half the gold in the Universe.""Shockwaves and light flashes from the collision travelled some 130 million light-years to be captured by Earthly detectors on August 17, excited teams revealed at press conferences held around the globe on Monday as a dozen related science papers were published in top academic journals."Why it matters: "[T]he data finally revealed where much of the gold, platinum, uranium, mercury and other heavy elements in the Universe came from.Telescopes saw evidence of newly-forged material in the fallout, the teams said — a source long suspected, now confirmed."Solved physics riddles.
