kinematic relativity

Special relativity, developed by Albert Einstein in 1905, is a cornerstone of modern physics. It applies to objects moving uniformly and reveals that the speed of light is a universal speed limit. Contrary to everyday experience, special relativity shows that space and time are interconnected, forming a four-dimensional space-time.12

Key concepts include:
* Relativity of Simultaneity: Events simultaneous for one observer may not be for another.3
* Time Dilation: Moving clocks run slower than stationary ones.2
* Length Contraction: Objects in motion appear shorter in their direction of movement.2
* Mass-Energy Equivalence: Mass and energy are interchangeable, famously expressed by Einstein's equation, E = mc².12

These effects are significant at speeds approaching the speed of light and have been confirmed by experiments with subatomic particles and precise clocks.4
