How time is distorted by galaxies -- by two cosmologists
Channel: Cosmic Blueshift
Date: 2022-07-01

In this video, two cosmologists from the University of Geneva explain how the distortion of time, an effect predicted by Einstein's theory of General Relativity, can be measured in our Universe. You will learn how time slows down near massive objects like black holes, how light becomes redder when it escapes gravitational wells and how one can test the laws of gravity.
