Gravitational lensing is a phenomenon that occurs when the gravitational field of a massive object, like a galaxy or a black hole, bends the path of light passing near it. This effect is a powerful demonstration of Einstein’s theory of general relativity, which predicts that mass curves the fabric of space-time, influencing the movement of light and objects. Gravitational lensing can magnify and distort the images of distant galaxies or stars seen from Earth, allowing astronomers to observe objects that are otherwise too faint or too distant to be seen by current technology. This phenomenon not only helps in mapping the distribution of dark matter (which does not emit light and is thus invisible through conventional means) but also in studying the properties of distant galaxies, detecting exoplanets, and testing aspects of general relativity. The ability to observe gravitational lensing effects has become a crucial tool in cosmology and astrophysics for understanding the structure and evolution of the universe.
