4 days agoIt’s mostly uniform. There is variation by location, but the maximum difference is +/- 0.7% from the nominal value of 9.8 m/s^2.
Here’s the full physics analysis. Check out Figure V.4.
TL;DR: It varies a lot. If the average gravity over the whole disk is 1.0, it’ll be 2.0 near the center and taper off to ~0.2 near the outer edge.
