Einstein's Theory of Special Relativity

Einstein's Theory of Special Relativity, proposed in 1905, revolutionized our understanding of space and time. It asserts that the laws of physics are the same for all observers, regardless of their relative motion. Key concepts include the idea that the speed of light is constant for everyone, leading to effects such as time dilation (time appears to pass slower for objects moving fast) and length contraction (objects appear shorter when moving close to light speed). This theory fundamentally changed how we view concepts of time, space, and causality in the universe.
