The Most Violent Event in the Universe Happens in Complete Silence — And One Is Overdue Near Us
Ready to change how you see the world? 🧠 I've broken down the deepest secrets of existence into 12 actionable principles.

Let me know in the comments On August 17th, 2017, every gravitational wave detector on Earth went off simultaneously. What they recorded was the merger of two neutron stars 130 million light years away, lasting less than two seconds. In those two seconds, the universe produced more gold than exists in all the stars of the Milky Way combined. In this video, Brian Greene walks through the complete physics of neutron star mergers, from what neutron stars are and how binary systems form, to the gravitational wave emission that causes the orbit to decay, to the collision itself and the r-process nucleosynthesis that produces every heavy element on the periodic table above iron. He explains what GW170817 revealed about where the gold and platinum and uranium on Earth actually came from. He introduces the double pulsar PSR J0737-3039, the closest known binary neutron star system, whose merger is scheduled in 85 million years. And he explains what a neutron star merger in our own galaxy would look like, why the gravitational wave signal would be detectable for over a minute, and why it would be the most spectacular and scientifically significant astronomical event in recorded human history. The most violent event in the universe passes through us in complete silence. Here is the physics of why, and what it means.
