written by Richard Epp
This web page contains a history of general relativity within the framework of Einstein's rotating disk thought experiment. Written in lay terms, it provides descriptions, explanations, and illustrations of how the Theory of General Relativity came about, why it displaced Newton's model of gravity, and why it became the next physics paradigm.

4. The Physical Setting

4F. Motion
  • 9-12: 4F/H2. All motion is relative to whatever frame of reference is chosen, for there is no motionless frame from which to judge all motion.
  • 9-12: 4F/H3c. In empty space, all electromagnetic waves move at the same speed—the "speed of light."

10. Historical Perspectives

10C. Relating Matter & Energy and Time & Space
  • 9-12: 10C/H4. A decade after Einstein developed the special theory of relativity, he proposed the general theory of relativity, which pictures Newton's gravitational force as a distortion of space and time.
  • 9-12: 10C/H5. Einstein's development of the theories of special and general relativity ranks as one of the greatest human accomplishments in all of history. Many predictions from the theories have been confirmed on both atomic and astronomical scales. Still, the search continues for an even more powerful theory of the architecture of the universe.
