Astrophysicists hear birdsong from faraway parts of the universe. 900 million light-years away, the fleeting sound was unlike anything they had ever heard before. and caused by massive ripples in spacetime These are gravitational waves that spread across the ดาวน์โหลด slotxo universe from a distance of more than 900 million light-years, wiping out the Earth and making a ping sound. Chick detector.Then, 10 days later, they heard another similar sound, Cosmic Twins, another gravitational wave sent an alarm to Earth's detectors, Chick. After careful analysis Both signals have been identified as being caused by unprecedented extreme events in deep space. That's a collision between a black hole and a neutron star. SCI's pair of collisions (or "mergers") are detailed in a new study published in Scientific American. Astrophysical Journal Letters on Tuesday With over 1,000 scientists from LIGO/Virgo and KAGRA, a multinational collaboration in the search for gravity, waves, two newly described events are named GW200105 and GW200115 for the date of their discovery. And it's the first evidence of an elusive merger.
