I find it quite amazing that I produced proof that the earth moves several days ago, and yet nobody has even tried to produce an argument to refute it, including someone who actually challenged me to produce such proof. I get the impression that there are lots of arguments by scientists against the geocentric theory, and that you've heard them all before, and have long passages to trot out which "proves" that all the observations can be explained by tortuous hypotheses which cannot be proved or disproved. However, nobody has even addressed my brother's statement that in the heliocentric theory the aberration of light for all stars is exactly the same, but in the geocentric theory the aberration of light should be different for all stars which are at different distances from the earth. Since the aberration of light IS the same for all stars, do you not agree that this seems to show that the earth is moving and that the stars aren't? I look forward to some sensible scientific arguments! Alan Griffin
