Relativistic Mechanics

Relativistic mechanics is a branch of physics that deals with the behavior of objects moving at speeds close to the speed of light. It was developed by Albert Einstein in the early 20th century. Unlike classical mechanics, which assumes time and space are absolute, relativistic mechanics shows that time can slow down and lengths can contract depending on the observer's speed. This leads to effects like time dilation and mass increase as you approach light speed, fundamentally altering our understanding of motion, energy, and gravity in the universe. It has crucial implications for modern technology, like GPS systems.
