Einstein’s Special Relativity: Time and Space Reimagined

Einstein’s 1905 theory showed that time and space are woven together into one fabric: spacetime.
Special relativity states that the laws of physics are the same for all observers moving at constant speed.
Nothing can travel faster than light—its speed is the ultimate cosmic speed limit.
Moving clocks tick slower, a phenomenon called time dilation.
Fast-moving objects contract in length along their direction of motion.
Mass and energy are interchangeable, captured in the famous equation 𝐸=𝑚𝑐².
GPS satellites must adjust for relativistic effects, or your location would be off by miles.
Simultaneity is relative—two events that seem simultaneous to one observer may not be for another.
Special relativity shattered the idea of absolute time, replacing it with relative time tied to motion.
This theory set the stage for Einstein’s later breakthrough: general relativity and the warping of spacetime by gravity.
