Einstein’s theory of gravity
According to Einstein’s theory, gravity is a geometric phenomenon inherent in warping of spacetime by matter as opposed to Newton’s theory which states that gravity is a force that emanates from matter.

Geometry on Curved Space
Spacetime is curved and is described by non-Euclidean geometry. The curvature of space determines how the sum of the angles and the perimeter of a triangle are related.

Gravitational Deflection of Light
According to Einstein, spacetime around a massive object is curved due to an object’s gravity. Therefore, the spacetime around that object is not flat but curved.

Perihilion shift of Mercury
The elliptical orbital pattern of planets cannot be stationary in curved space and must precess. However, the observed astronomical data revealed a discrepancy in Mercury’s precession as predicted by Newton’s theory, but later solved by Einstein’s theory.
