The free preview (together with such papers as indicated by dlzc) looks sufficient to me! Cheers, Harald ------------------------------------ J. P. Wesley1 (1) Weiherdammstrasse 24, 7712 Blumberg, Germany Received: 9 March 1990 Abstract Because terrestrial sources radiate in all directions, collimation cannot produce a beam fixed in direction relative to absolute space. Therefore, terrestrial aberration, even though present, cannot be observed; and terrestrial aberration cannot be used to measure the absolute velocity of the closed laboratory (contradicting a prior claim in this journal). In other words, the large parallax of terrestrial sources frustrates the observation of aberration. Key words measuring absolute velocity - Bradley aberration Apparently the proposed experiment [I] using Bradley aberration in the closed laboratory to measure the absolute velocity of the laboratory will not work. The principles already stated remain valid; but an additional effect, an artifact, which was overlooked in the original proposal, will frustrate a positive result. In particular, it is apparently impossible to obtain a terrestrial source that will radiate in a single direction fixed relative to absolute space. All known atomic and molecular light sources radiate in all possible directions. The velocity of light emitted is not affected by the absolute velocity of the source. However, to obtain a unidirectional light beam, that might be used to simulate starlight in the laboratory, a mask, a collimator, or cavity (such as in a laser) must be employed; and these devices unfortunately move with the [..] |
