Gravitational lensing explained! 👩🏻‍🏫 Anything that has a mass warps the underlying fabric of the universe: spacetime. This animation shows how light moves around an object warping spacetime, then around a cluster of galaxies. When light passes close to something as massive as a galaxy cluster, its intense gravity bends and magnifies light from even more distant objects behind it, making them appear brighter, stretched, or even duplicated. This phenomenon, called gravitational lensing, lets u
