The theory of General Relativity (GR), developed by Albert Einstein, provides an elegant mathematical framework to explain one of the most common phenomena – gravitation – by revealing that gravity is fundamentally a manifestation of geometry. Essentially, it is a theory of space and time and gravity, where the force of gravity is attributed to the bending and warping of the spacetime. This explains phenomena ranging from falling feathers to the motion of galaxies on the grandest scale and has practical applications in modern technology ranging from relativistic corrections for the accuracy of Global Positioning System (GPS) to telecommunications. The theory has led to various predictions, such as the precession of Mercury, the bending of light, etc., all of which have been experimentally confirmed.
