He Proposed The General Theory Of Relativity
In 1916, Einstein published his general theory of relativity, a unified account of gravity as a geometric property of space and time, or spacetime, that generalizes special relativity and Newton's law of universal gravitation. General relativity aided in the modeling of the universe's large-scale structure, and its predictions have been confirmed in all observations and experiments conducted thus far. It has evolved into a crucial tool in modern astronomy, allowing researchers to better comprehend phenomena such as black holes and gravitational lensing. The General theory of relativity is one of the major accomplishments of Albert Einstein.
Einstein noticed that heavy objects generated a distortion in space-time when he worked out the equations for his general theory of relativity. Consider placing a large object in the trampoline's center. The thing would dimple the fabric as it pressed down into it. If you tried to roll a marble around the edge of the trampoline, it would spiral inward toward the body, pulling it in the same manner as a planet's gravity pulls on rocks in space.
When light bends around a large object like a black hole, it acts as a lens for whatever lies behind it. This method is commonly used by astronomers to investigate stars and galaxies that are hidden by huge objects.
