Earth-Moon Spacetime Curvature

This webpage is part of

Multiple Curvatures

Here, we do not take into account the curvature of spacetime made by the sun and other planets or galaxies. So, contrary to the drawing in the main Webpage, we are not in a pure flat spacetime between the Earth and the Moon. Moreover, this figure is a kind of "snapshot" because the Moon would crash on the Earth if gravity were the only force in action. The centripetal force due to the movement of the Moon around the Earth is not considered here because it concerns Newtonian Physics.
