Gravitational acceleration depends on your frame of reference, and can always be made to be zero by picking a free-falling frame (which is what is considered to be an inertial frame in GR). Curvature is a tensor, so if it's nonvanishing in one coordinate system, it's nonvanishing in all other coordinate systems. | |

| Aug 16, 2016 at 11:31 | comment | added | CuriousOne | The local gravitational acceleration is a pretty good measure in the weak field. Within the solar system it's good to one part in $10^{10}$, I believe. | |

| Aug 16, 2016 at 11:19 | comment | added | user108787 | Do you mean locally, or on a cosmological scale? | |

| Aug 16, 2016 at 11:18 | comment | added | dllhell | @EmilioPisanty I did and didn't find an answer do you have an answer? | |
| Aug 16, 2016 at 11:16 | comment | added | Emilio Pisanty | Have you done any prior research? Did you try e.g. Wikipedia? | |
