Light deflection

Light deflection is the process where the path of light bends when it passes near a massive object, like a star or black hole. This bending occurs because gravity warps the fabric of space-time, causing light to follow a curved trajectory instead of a straight line. Think of it like a boat moving across a warped water surface; the boat's path curves because of the water's shape. This effect, predicted by Einstein's theory of general relativity, has been observed around massive celestial bodies and helps astronomers understand the distribution of mass in the universe.
