Gravitational Waves

This illustration provided by researchers in June 2023 depicts gravitational waves stretching and squeezing space-time in the universe. On Wednesday, June 28, 2023, researchers reported signals from what they call low-frequency gravitational waves — changes in the fabric of the universe that are created by huge objects moving around and colliding in space. It took decades of work by scientists across the globe to track down the evidence for these super-slow wobbles.
