In 1918, two German physicists, Lense and Thirring (Lense, J. & Thirring, H., 1918. Physikalische Zeitschirf. 19:156) considered the actions of elements inside of a rotating shell. Very similar to Gerber’s* work above, Lense and Thirring sought to demonstrate what the behavior of things like pendulums, satellites, etc. would be like if the universe were a rotating shell.
They concluded that the behavior of these entities would be as we observe them behaving, although not exactly. Lense and Thirring discovered a new effect, a twisting of an orbit which is commonly called “frame dragging” or the “Lense-Thirring effect.” Furthermore, they were able to erect the postulation that the gravitational field inside of the rotating shell was not zero, as would be the expected outcome in the Newtonian gravitational model.
They discovered that there were forces acting away from the center in the shell that were analogous to centrifugal and Coriolis forces. Hence, in this particular geocentric model, centrifugal and Coriolis forces are no longer “fictitious forces” or “effects,” but identifiable and viable gravitational forces. Consequently, heliocentric proofs such as the earth’s equatorial bulge, the stationary satellite, and the Foucault pendulum are equally justifiable to prove geocentricity.

*the German physicist Paul Gerber (Gerber, P., 1898. Zeitschr. f. Math. u. Physik, 43:93) showed that if the universe rotates around the earth once per day instead of the earth rotating on its axis once per day, then the usual evidences for heliocentrism, such as the Foucault pendulum, satellites, etc. would appear precisely as we see them.
