Relativity theory is a fundamental theory in physics that describes how objects move through space and time. It was developed by Albert Einstein in the early 20th century and has since become one of the most influential scientific theories.

Key Concepts

  • Special Relativity: This theory describes the behavior of objects moving at constant speeds, particularly those approaching the speed of light. It introduces the famous equation E=mc², which shows the equivalence of mass and energy.
  • General Relativity: This theory extends special relativity to include gravity, describing it as the curvature of spacetime caused by mass and energy.

Impact

Relativity theory has had a profound impact on various fields, including:

  • Astronomy: It has allowed us to understand the behavior of black holes and the expansion of the universe.
  • Technology: It has influenced the development of GPS systems and other technologies that rely on precise timekeeping.
