This is one of the things about aberration that I do not understand. If photons which have no length and mass hit a telescope lens at right angles, how is filling it with water to make a difference? I don't know why anyone even thought of it that way. There is the Ether Drag Theory: NASA Laser Lunar Ranging Analysis of the lunar ranging experiment in 2009 by D Gezari [5] [6] prove the Sagnac effect as first order, and suggest either 'c' non- constant or a quantum field 'ether' dragged by the planet. (wikipedia Ether Drag) Also, following the link: The speed of laser light pulses launched from Earth and returned by a retro-reflector on the Moon was calculated from precision round-trip time-of-flight measurements and modeled distances. The measured speed of light (c) in the moving observers rest frame was found to exceed the canonical value c = 299,792,458 m/s by 200+/-10 m/s, just the speed of the observatory along the line-of-sight due to the rotation of the Earth during the measurements. This is a first-order violation of local Lorentz invariance; the speed of light seems to depend on the motion of the observer after all, as in classical wave theory, and implies that a preferred reference frame exists for the propagation of light. However, the present experiment cannot identify the physical system to which such a reference frame might be tied. and implies that a preferred reference frame exists for the propagation of light Curioser.

Its not that hard. The faster an object moves, the less aberration there is. That is easily shown Consider two object moving downward (on this page) at different speeds. From an observer at rest wrt the page you'd see these paths (over time) .. o O .. o O .. o O .. O .. O A moving observer would see .. o O .. o O .. o O .. O .. O The faster moving O is less aberrated. As light moves slower in water than air, then the light should show more aberration in a water filled telescope > If photons which have no length and mass hit a telescope lens at right > angles, how is filling it with water to make a difference?

Andersen is kidding himself. > > Your point after I've made it for you, you drunken old fool. HST was not designed to do precise astrometry. Hipparcos was. The Hipparcos catalog includes over 100,000 stars measured to a median accuracy of about 0.001 arcseconds. The stars in this catalog include LHS 50, with a radial velocity of 308 km/s, and LHS 64, with a radial velocity of -260 km/s. Differential aberration as predicted by emission theories should have been easy to observe. Conclusion: Light travels at constant c. Emission theories are disproven, as usual. Jerry
