Relativity (PhysicsThis excellent, semi-technical account includes a review of classical physics (origin of space and time measurements, Ptolemaic and Copernican astronomy, laws of motion, inertia, and more) and coverage of Einstein's special and general theories of relativity, discussing the concept...
Einstein’s Theory of Relativity There are really three theories of relativity: • Relativity pre-Einstein (Galileo) • Special Theory of Relativity (1905) • General Theory of Relativity (1915) Relativity is concerned with the question: What is the nature of space and time? Absolute space...
In his general theory of relativity, Einstein said that gravity, like time, is not always the same. Gravity changes as observers speed up or slow down. He also said that gravity from very large objects, such as stars, could turn the path of light waves that passed nearby. This seemed un...

Even on the Special Relativity bus,however, your wristwatch would show 3: 01 after one minute and 3: 05 after five minutes.So is time standing still or not? Well, it's all relative.Einstein realized that time and space are relative to the speed of light. If you are moving at an oc...
