Relativity
General Relativity, proposed by Albert Einstein in 1915, is a fundamental theory that describes the gravitational force as a curvature of spacetime caused by mass and energy. This theory extends the principles of Special Relativity to include accelerated reference frames and introduces the revolutionary concept that gravity is not a force, but a manifestation of spacetime curvature.
Special Relativity, formulated by Albert Einstein in 1905, revolutionized our understanding of space, time, and energy. It introduced the concept that the laws of physics are the same in all inertial frames of reference and that the speed of light is constant, regardless of the motion of the observer or the source. This theory fundamentally changed the way we perceive the universe, showing that measurements of space and time are relative and depend on the observer’s state of motion.
