A ring of light that senses every turn of the planet. The new TRIO gyroscope in the Gran Sasso underground lab captures Earth’s rotation with exquisite precision. In the future, such devices will aim for the ripples of spacetime — gravitational waves from distant cataclysms.
🎯 Giant ring lasers with a perimeter of a hundred meters can sense how an earthquake on the other side of the world changes the planet’s rotation speed.
