General Relativity is a theory of gravity proposed by Albert Einstein in 1915. It explains how massive objects interact with one another and how gravity affects the fabric of space and time. According to this theory, gravity is not a force between masses, but rather a curvature of space and time caused by the presence of mass and energy.
2015 marked the 100th anniversary of the publication of Einstein's theory of General Relativity. This theory revolutionized our understanding of gravity and has been confirmed through numerous experiments and observations. It also laid the foundation for many modern technologies, such as GPS and black hole detection.
While Newton's theory of gravity treats gravity as a force between masses, General Relativity explains gravity as a curvature of space and time. Additionally, General Relativity predicts that gravity can also affect the path of light, while Newton's theory does not account for this effect.
Some of the key predictions of General Relativity include the bending of light in the presence of a massive object, the existence of black holes, and the expansion of the universe. It also predicts the existence of gravitational waves, which were recently detected for the first time in 2015.
General Relativity has been confirmed through various experiments and observations, such as the bending of starlight during a solar eclipse, the precession of Mercury's orbit, and the observations of gravitational lensing. It has also been tested and validated through mathematical calculations and computer simulations.
