I think I do agree with you if I am reading you correctly Jack. I have worried about it at times. The problem for me and you is that we may not know the mathmatics where with astronomers calculate the movements and speed of celestial bodies. Robert explained to us how the distance from the sun was confirmed. I still do not have a clue what he was talking about. But I do have faith in the geometry. In science only few things are certain. Such as the internal angles of a triangle always add up to 180 degrees. I do not think there is anything wrong with making logical assumptions if they are based upon reasonable observation. For example it is reasonable from observation to assume that the sun orbits the earth. Yet this does not make it absolutely certain. Scientifically that is. We know it to be true from faith, but that is not allowed into the scientific debate. It is allowed as an assumption to be proved, just like any other assumption. To give the atheist his due, It is also reasonable to assume that the planets are similar in weight and composition to our earth. We may take as close to true the calculated mass of the earth. Thus taking the reasonable assumptions I outligned, and observing that these planets do orbit the sun, it is not unreasonable to accept the calculations of the weight of the sun, as would be necessary to allow for the observed orbits of these planets. under proven newtonian laws of motion. It would be unreasonable to say that these laws do not apply off world. Also we must carefully evaluate our language, when we say things like I believe such and such. Quite often we merely affirm an opinion, rather than making an act of faith. We must not confuse for example presumption with assumptions. "Assuming this to be true", is merely making a conditional requirement for a hypotheses to be evaluated. It is not a statement of truth. One might say, assuming this to be a lie, and proceed from there... NEVERTHELESS YOU ARE ABSOLUTELY CORRECT IN HOW THEY DEALT WITH THE AETHER EXPERIMENT. From their point of view, because of the nil result they preferred to believe that there was no aether. From our point of view we preferred to believe that it proved the earth was not moving. Yet the real truth of the matter could be that the aether does exist, but that it is not a physical entity which can be detected like a river through which we flow or pass, or that light waves will bend. To say that it is, is like saying "assuming this to be true". They cannot presume it to be true. Which they did of course and which we do as well. My third point could just as well be true. And so the MM experiment cannot prove anything, which is what I said months ago...

You will notice the use of the word *believe* where I felt it was necessary. When Michaelson and Morley performed their interferometer experiment they were trying to prove that the earth moved through the aether. OK so far? Because they got a nil result (no light interference fringes) they concluded that the earth did not move. However further interferometer experiments were set up to try and explain why they got a nil result or failure as some scientists preferred to call it. This was because everyone *believed* the Earth did move and they therefore could not accept the results. This, as you probably know, caused quite a stir and upset not a few scientists. The preferred conclusion of the experiments was, not that the Earth was stationary, but that there was no aether even though it had been given a 'constant' by Max Plank. This aether was *believed* to exist because it was *believed* light needed a medium in which to travel. Then along came Einstein and did away with the aether with his strange relativity theories and all because nobody wanted to *believe* that the Earth looked as though it was stationary. So when you start quoting GR etc. I have to take a sceptical view because of the level of belief that is needed. I will be happy to consider anything on this subject that does not contain any guesswork. I would like to know if there is anyone else on this forum who shares my view? Jack
