Albert Einstein, a brilliant physicist, revolutionized the understanding of the universe with his Theory of Relativity. This theory comprised two major parts: the Special Theory of Relativity and the General Theory of Relativity. The Special Theory, published in 1905, introduced the concept of spacetime continuity, where space and time are interconnected and relative to the observer's frame of reference. It also postulated that the speed of light in a vacuum remains constant, regardless of the motion of the light source or observer. The General Theory of Relativity, published in 1915, extended these ideas to include gravity. It proposed that massive objects warp spacetime, causing other objects to move along curved paths. Einstein's groundbreaking work laid the foundation for our modern understanding of the cosmos, altering perceptions of space, time, and gravity, and continues to inspire scientific advancements today.
