Dr Bridgman has received my questions concerning modern cosmology at "Geocentrism: Does NASA use Geocentrism?" I have copied the questions here for readers consideration and answers if they so wish.
Q1 - according to Kepler’s first law, "The orbit of every planet is an ellipse with the Sun at one of the two foci.", yet the center of mass of the sun is always moving around the solar system barycenter. Therefore, as the foci of the planets ellipse moves, does this therefore invalidated the first law, or does the entire ellipse move with the moving foci at the center of the sun?
Q2- If the planet actually orbits the solar system barycenter, why then does Kepler’s first law say otherwise?
Q3 - Doesn't the solar system barycenter exclude the center of the sun as being a foci of the planets elliptical orbit?
Q4- If Kepler’s first law is used in planetary flight paths, this means the solar system barycenter must be ignored, which thereby seems to invalidate Newton’s laws of motion around a common barycenter. Please comment.
Q5- Why do Kepler’s laws assume all planets have an elliptical flight path, yet when we take into account the Earth-moon system, the earth moves around the Earth - moon barycenter every month whilst moving along its orbital path around the sun. If the trace out the flight path of the earth relative to the center of mass of the sun as the foci of the ellipse, the earth cannot possibly be traveling in an ellipse, but must move through "absolute space" in a flower pattern centered on the solar system barycenter. As the earths flight path does not fit into the elliptical orbit pattern required by Kepler’s laws, how are Kepler’s laws used to accurately determine the flights paths of other planets relative to the earth?
Q6 - If the earth is orbiting around the Earth-moon barycenter every month, why don’t we see the apparent motion of the sun around the earth vary in velocity as the earth gains and loses a velocity component due to its motion relative to the “fixed” sun? In other words – during the monthly cycle there is a time when the earth must orbit in a prograde manner relative to the sun, when orbiting the earth –moon system. Later during the month, the earth continues its earth-moon barycenter motion and must move in a retrograde motion relative to the fixed sun.

Q7- How are these relative prograde and retrograde motions of the earth on a monthly basis taken into account in the flight path calculations?
Q8- How are the calculations consistent with Kepler’s laws, when the earths flight path through space is not an ellipse, but a complex flower shape?
Q9 - According to Kelper’s laws, the earth orbits the sun every year in an ellipse. Accordingly the velocity of the earth varies from 30.287 to 29.291 km/s, yet the earths orbital velocity around the earth-moon system is approximately 0.012km/s. This means that if we take into account the monthly orbit velocity of the earth around the E-M barycenter, the earths velocity around the sun will vary from 30.287+-0.012 to 29.291+-0.012, which means the earths orbital velocity around the sun does not comply with Kepler’s laws. How is the flight path of the earth and planets relative to the earth calculated when the earths flight path around the sun does not comply with Kepler’s laws?
Q10 – If the earth moves around the E-M barycenter every month, why don’t we observe a monthly parallax of the sun?
Q11 – The sundial is constructed using the equation of time which excludes the motion of the sun around the solar system barycenter. As the sun moves quite a large amount over many years, as shown in this video, - http://www.youtube.com/watch?v=1iSR3Yw6FXo
why is the suns motion ignored in the equation of time? Please provide the calculations to demonstrate the suns motion around the solar system barycenter can legitimately be ignored in the equation of time.
