Hello guys It is a General introduction to general relativity. General relativity theory was given by Albert Einstein after 16 years of Special relativity. General theory of relativity is a Theory of gravity. Before that there was Newton's theory of gravity.
Newton told that every matter in the universe attract each other with the force of gravity that force of gravity is directly proportional to the product of the masses and inversely proportional to the square of distance between them.
There was a problem with this theory of gravity that this theory of gravity couldn't explain why does matter attracts, means how matter attract each other. what is the reason behind that attraction.
Suppose I have to attract an apple on ground I have to make a contact with the Apple to attract it but gravity attract everything without any contact. So how that works was the problem behind the Newton's theory of gravity. So our one genius named Albert Einstein figured out this problem and work on this.
So with genius mind Albert Einstein proposed his theory of gravity which tells that gravity is not a force it is just the result of curvature of space and time due to matter.
Space time is considered as fabric of universe and that fabric is curved around mass or energy as shown in the pic.
Einstein worked on its mathematical framework and Einstein field equation. And that Equation uses Tensor Calculus to explain gravity.
