The theory of relativity is one of the most significant scientific developments of the 20th century and was developed by Albert Einstein. This theory redefined the concepts of space and time under conditions of high velocities and strong gravitational fields where Newtonian mechanics proved inadequate. Classical transcending Newtonian physics, this theory provides a deep understanding of the relationships between time, space and gravity, and consists of two components: special relativity and gen

The Einstein ring is a special case of the gravitational lensing effect. It occurs when light from a more distant light source, aligned with a massive celestial object (such as a galaxy or a black hole), is bent by the gravitational influence of this object, resulting in the light appearing as a perfect ring in the observer's field of view. This phenomenon is one of the predictions of the theory of relativity and was first theoretically expressed by Albert Einstein in 1936.Physical BasisEinstein
