General relativity Quote by Steven Weinberg
““In its final form, the general theory of relativity was just a reinterpretation of the existing mathematics of curved spaces in terms of gravitation, together with a field equation that specified the curvature produced by any given amount of matter and energy. Remarkably, for the small densities and low velocities of the solar system, general relativity gave just the same results as Newton's theory of gravitation, with the two theories distinguished only by tiny effects like the precession of orbits and the deflection of light.””
About This Quote
Source Book: Gravitation and Cosmology by Steven Weinberg, 1972
General relativity reinterprets curved‑space mathematics as gravity, matching Newtonian predictions in everyday conditions but differing in subtle, high‑precision effects.
In simple terms: Einstein’s theory uses geometry to describe gravity, agreeing with Newton for most cases but showing tiny differences.
