Theory of Relativity (related discussions)

The Theory of Relativity, developed by Albert Einstein, includes two parts: Special Relativity and General Relativity. Special Relativity, introduced in 1905, explains that space and time are interconnected, affecting how we perceive events depending on our speed. It shows that the speed of light is constant for everyone, leading to concepts like time dilation, where time moves slower for faster-moving objects. General Relativity, introduced in 1915, expands this idea, explaining gravity not as a force but as the curvature of space-time caused by mass. Together, these theories transformed our understanding of physics and the universe.
