We know the accelerations and forces in an orbital system to an exquisite degree of precision and have done since Newton set them out. All that we have learned since are small refinements to Newton’s great work. We know them because we measure the masses, we measure the orbital geometry, we measure the gravitational forces. It all fits together. It’s not a presumption but a conclusion of reason based on a vast body of evidence. To claim otherwise is pure obscurantism.Hec, this is where your argument fails. You cannot presume that you understand the dynamics accelerations and forces fully.
Such as? We know the gravitational model works because it describes observation with an extremely high degree of precision, and because we use it to put satellites into orbit, to put men on the moon and to send probes to distant planets. What are these other models that work as well? If you put one forward be sure that you can show how it predicts the geometry of observed orbits to as a high a degree of precision as Newtonian mechanics or GR.The gravitational/inertia model is merely one model amongst many which may or may not work.
Overwhelming evidence.You have no proof that gravitation/inertia is the force behind the motions of the planets.
Overwhelming evidence - the sun’s gravitational field hugely dominates at the earth - no extra-solar body or group of bodies has a gravitational field at the earth greater than a millionth that of the sun.Even if it is, you have no proof that other masses in the universe offset and counterbalance the motions of the solar system in order to keep the earth positioned in the centre of the universe
No, I cannot. You are right there - postulates of supernatural and miraculous deeds always trump natural explanations, but they have no explanatory power. As I said to hans, if you are happy with angels or God acting supernaturally as an explanation, I don’t see why you bother with poor and garbled attempts to demonstrate your position by natural science.Nor can you prove that God is not supernaturally holding the earth in its central position.
The vast majority of Catholics have no difficulty whatsoever in believing with all their heart, mind and soul in God’s establishment of a indestructible Church, while simultaneously being perfectly willing to accept the rotation, orbit and proper motion of the earth. Have you ever thought that your insistence that one relies on the other might be a defect of understanding on your part?Corner stones are laid so that a structure will not move. So if God’s cornerstone for the earth was ineffective and so now the earth spins and wizzes throughout the solar system and the universe, then how can we have any confidence in the cornerstone that God laid for our church?
