Special relativity is a fundamental theory in physics that describes how the universe works at high speeds. It was proposed by Albert Einstein in 1905 and has since been confirmed by numerous experiments.
Key Concepts
- The Speed of Light: The speed of light in a vacuum is constant and is approximately 299,792 kilometers per second.
- Time Dilation: Time can slow down for objects moving at high speeds relative to a stationary observer.
- Length Contraction: Objects moving at high speeds will appear to be shorter in the direction of motion.
- Mass-Energy Equivalence: Energy and mass are interchangeable, as described by the famous equation E=mc².
