Dear Phil, Check out George Airey's water filled telescope. Since light was supposed to travel 1.5 times slower in water the aberration of the stars should have produced ellipses 1.5 times larger. They didn't and so aberration was discounted as evidence for the Earth orbit round the Sun. Jack Lewis Yes I get it now Jack, hence the time it took for my response. But from the data I have gotten so far, there is nothing under aberration that connects it with the speed of the object or the observer alone, but with both. The few universities articles I have found so far are on different planets. Still looking. One things seems to be certain though, it is all a matter of relativity. So far this is how it relates to our own debate, according as to how I get it in my own simple words. Aberration (optical) is the distortion of a view of a moving object or moving observer in the camera of an observer, caused by the following. The different angles of observation of different parts of the object/s being viewed. Call this the frame of view. The more oblique the angle, say to the left hand star, the greater is the time delay for that part of the picture to arrive at the plate, than from the star near it at right angles. This would result in no distortion if the picture frame had nothing moving or changing . But if the object or observer is moving causing varying angles of view, the object will be distorted in size. If it was a comparison of two stars in the frame of view for example, their relative positions would be distorted to appear closer or further apart than they actually were at a particular time because of the different time lapse for each part viewed. So far I have found nothing in this to confirm Alans statement that the peripheral speed at the rim being greater has anything to do with it in a geocentric model, as the relative positions on an observers /retina/plate would remain constant to the radial speed. However parallax would/ could have an effect which observation would indeed be affected by distance to the rim. I think we have to concede there is relative movement between the earth and the cosmos which is consistent with annular orbit either of the earth or the sun. Notice I said relative motion. This has nothing to do with Alans claim about linear speed/aberration, which proved nothing in support of a moving earth that cannot just as easily be supported by a moving cosmos. It seems necessary, to explain the phenomenon of aberration, and also the doppler effect observed and alleged to be due to the annular orbit of the earth, that in addition to a rotating cosmos every 24 hours, it would also be necessary for it (cosmos) to be gyrating every 24 hours at the angle of inclination given to the earth. This by the way is a natural phenomenon in rotating masses if unbalanced either in mass distribution or gravitational force. They have the earth doing it! This would explain all the obdervation/mechanics of a sun centred earth orbit, and the seasons. etc. And no doubt, Alan may call it pseudo science mumbo jumbo if he likes. Philip If any man among you seem to be wise in this world, let him become a fool, that he may be wise. For the wisdom of this world is foolishness with God: ----- Original Message ----- From: "Philip" <joyphil@xxxxxxxxxxx> To: <geocentrism@xxxxxxxxxxxxx> Sent: Saturday, August 07, 2004 2:17 AM Subject: [geocentrism] Re: Challenge Any body know what > the speed of light is through glass or water?
