[00:00:00]Did you know that on August 17th, 2017, humanity witnessed the universe's most violent jewelry factory in action? At exactly 9:41 a.m., detectors on Earth felt space-time itself ripple. Two neutron stars, >> [music] >> each weighing more than our sun, but crushed into spheres just 12 miles wide, had been spiraling toward each other for millions of years. When they finally collided 130 million light-years away, >> [music] >> the impact was unimaginable. Picture this. Objects so dense that one [music] teaspoon weighs 6 billion tons crashing together at 30% the speed of light.

[00:00:37][music] The collision lasted mere seconds, but created temperatures of 100 million degrees, forging more gold than exists in Earth's entire crust. Within [music] minutes, thousands of telescopes worldwide swung toward the explosion site. For the first time ever, scientists could see, hear, and feel the same cosmic event through gravitational waves, light, [music] and gamma rays simultaneously. This single kilonova solved mysteries that had puzzled scientists for decades, [music] revealing where heavy elements come from and helping measure how fast our universe expands.
