equivalence principle


A basic postulate of general relativity, stating that at any point of space-time the effects of a gravitational field cannot be experimentally distinguished from those due to an accelerated frame of reference.
Example sentences
  • Indeed, massless moduli would probably lead to long-range forces that would compete with gravity and violate the equivalence principle - the cornerstone of general relativity - at an observable level.
  • Both findings - about the strong equivalence principle and the gravitational constant - boost Einstein's theory,’ added Turyshev.
  • For instance, the equivalence principle one of the cornerstones of relativity states that in freely falling reference frames, the outcome of any non-gravitational experiment is independent of when and where it is carried out.
