After the invention of special relativity, Einstein tried for a number of years to invent a Lorentz-invariant theory of gravity, without success. His eventual breakthrough was to replace Minkowski spacetime with a curved spacetime, where the curvature was created by (and reacted back on) energy and momentum. dr kharazi

WebApr 11, 2024 · A Riemannian metric is a metric tensor. Every smooth manifold has a Riemannian metric, which means you can make any smooth manifold into a Riemannian manifold. A Riemannian manifold is a real, smooth manifold with a positive-definite inner product on the tangent space at every point given by the metric tensor. Here, positive … WebMar 11, 2024 · 1 Answer. Curvature is independent of coordinate system. If a metric is flat, it is flat. (For example, in R 2, we have the standard metric d s 2 = d x 2 + d y 2; when we switch to polar coordinates, we have d s 2 = d r 2 + r 2 d θ 2. Christoffel symbols may be nonzero, but the curvature is still 0 .) Of course flat spaces have submanifolds of ...
