"You have it backwards. In a geocentric model, so-called fititious or pseudo forces are generated naturally. It is GR that is forced to call them fictitious or psuedo forces, not geocentricity."

Now something moving:

Coriolis effect


"Your ignorance is astounding. Geocentric models are used to calculate moon flights. The only time the sun is used is for interplanetary flights."

Good look for your space ship!


"Wrong again. They are talking about the foundation of GR. CS are interchangeable by definition."

This is only true within physics for inertial reference frames or non inertial reference frames with the same acceleration vector. If not you have to change your physics.
Have you ever tried Hamiltonian mechanics?

"Educate yourself."

That it is impossible to physically distinguish between geocentric and heliocentric models is the point of the work of Mach, Einstein and Hoyle and recognized by their published statements.

Coriolis effect

A really cool observation of this effect is at the playground!

hAVE A COUPLE OF FOLKS FACE EACH OTHER ACROSS this THING (Wanna buy a caps lock key?), spin it and toss a ball back and forth!
