General relativity was the revolutionary theory proposed by Albert Einstein in 1915 that proposed a new way of explaining the nature of gravity. Previously, Einstein had said that distance and time are not fixed; they were based on the motion of the observer with his Theory on Special Relativity (It’s relative!). Now, with his new theory, gravity was established as being equal to acceleration, and, thus, gravity had the capability of warping space!
History and Development
Introduced by Albert Einstein in 1915 after the last theory on the nature of gravity proposed by Isaac Newton about one hundred and fifty years earlier, the Theory of General Relativity has achieved colossal fame, even after Einstein won the Nobel Prize for work in another field – the photoelectric effect – in 1921. General Relativity is based on the Equivalence Principle, which states that gravitation and acceleration are two phenomena describing essentially the same underlying concept.
