 What are the postulates of General Relativity? Alexander Poltorak, Adjunct Professor of Physics at the CCNY: "In 2005 I started writing a paper, “The Four Cornerstones of General Relativity on which it doesn’t Rest.” Unfortunately, I never had a chance to finish it. The idea behind that unfinished article was this: there are four principles that are often described as “postulates” of General Relativity:

1. Principle of general relativity

2. Principle of general covariance

3. Equivalence principle

4. Mach principle

The truth is, however, that General Relativity is not really based on any of these “postulates” although, without a doubt, they played important heuristic roles in the development of the theory."
