  • One method relies on gravitational lensing, an effect predicted by Albert Einstein's general theory of relativity and first demonstrated by Arthur Eddington during a solar eclipse in 1919.
  • Einstein's general theory of relativity
  • Albert Einstein's general theory of relativity
  • special and general theory of relativity

And so space-time is essential for Einstein's theory of relativity, both the special theory and the general theory of relativity.

Morphology

general + theory + of + relativity

The phrase is compositionally formed from 'general' + 'theory' + 'relativity', so a learner who knows those words can infer it refers to a broad theory concerning relativity (i.e., a wide-ranging theory about relativistic effects). However, the detailed scientific content (Einstein's specific claim about gravity as spacetime curvature and the technical distinction from 'special relativity') is specialized and not predictable from the constituent words alone, so the meaning is only partially transparent.

Etymology

General theory of relativity was named by Einstein to show it was a more general version of his earlier 'special theory of relativity'; here general means it covers more situations and relativity shows that measurements can change depending on who is watching. A simple picture is a stretched sheet (space-time) that bends under a heavy ball, and that is why the theory today describes gravity as the bending of space-time.
