Yep. The official explanation is that the surface of the earth is accelerating upwards through space-time.

I sometimes wonder if and FEer even understands what GR is and what it means. First of all, it postulates, and is dependent upon the Newtonian concept of gravity that matter “attracts” matter being correct. It is just a proposed theory has to how/why that happens. In Einstein’s field calculations, G is the gravitational constant from Newton's law of gravitation, G

*uv* is the metric tensor, which describes spacetime and gravitational potential and T

*uv* is the stress-energy tensor, which is the source of the gravitational field. So if you want to try and use GR to support UA, you can’t do so without also accepting the Newtonian concept of gravity that matter “attracts” matter. If GR is true, then it is also true that matter “attracts” matter. It is, after all, a theory of gravitation.

The how or why shouldn’t be relevant to FE because no matter how or why it happens, ultimately, the fact that it does ends with a sphere earth.
