12 minutes all ages Telescopes built to detect electromagnetic waves, like visible light, infrared, radio waves, and other forms, give us the ability to see objects and events at great distances in the universe, and far back in time. Today, a new type of instrument, the “gravity wave telescope”, is giving us the power to “hear” cosmic events beyond the sight of ordinary telescopes. Gravity waves are ripples in spacetime created by events like collisions between black holes, and powerful processes that took place in the earliest times of our universe. The Dutch Black Hole Consortium is currently building an enormous underground gravity wave detector, called the Einstein Telescope. When completed, this instrument will provide unprecedented insight into the nature of the universe and its origin, allowing scientists to probe cosmic secrets that light waves cannot illuminate.
