As a beginner which book should i study for GTR & does it require to have knowledge of tensor algebra ? If yes then suggest me a book for that too .

The General Theory of Relativity is a scientific theory proposed by Albert Einstein in 1915. It is a theory of gravity that explains how objects with mass interact with each other and how space and time are affected by these interactions.
The General Theory of Relativity extends Newton's theory of gravity by incorporating the concept of curved spacetime. It explains gravity as the curvature of spacetime caused by the presence of mass, whereas Newton's theory described gravity as a force between objects with mass.
There is a substantial amount of evidence that supports the General Theory of Relativity. Some of the most notable evidence includes the bending of light around massive objects, the precession of Mercury's orbit, and the gravitational redshift of light.
According to the General Theory of Relativity, time is not absolute but is relative to the observer's frame of reference. In the presence of a massive object, such as a planet or star, the gravitational pull causes time to pass more slowly. This is known as time dilation.
Yes, the General Theory of Relativity can be applied to the entire universe. It is a fundamental theory that describes the behavior of gravity on a large scale, from the smallest particles to the largest galaxies. It has been extensively tested and has been found to accurately predict the behavior of the universe.
