The Strange Phenomenon of Gravitational Lensing #gravity #universe #space #shorts #youtubeshorts

Have you ever seen a distorted or magnified image of a distant object behind a glass lens? This is called refraction, and it happens when light bends as it passes through a medium with a different density or refractive index. But did you know that something similar can happen in space, without any glass lens? This is called gravitational lensing, and it happens when light bends as it passes near a massive object with a strong gravitational field. Gravitational lensing is one of the predictions of Einstein’s theory of general relativity, which describes how gravity affects space and time. Gravitational lensing can create various optical effects, such as multiple images, rings, arcs, or crosses of the same object .Gravitational lensing can also act as a natural telescope, amplifying the brightness and size of distant objects that would otherwise be too faint or small to see.Gravitational lensing is a powerful tool for studying the universe, as it can reveal hidden objects such as black holes, dark matter, or exoplanets.
