The boost/slingshot effect comes about because the space craft falls towards Earth, and then falls backout so that it keeps its relative velocity to Earth the same on the way in as out, but since Earth is moving, Earth's speed around the sun gets added to the spacecraft's speed. The first paragraph of his Introduction says something similar: "Planetary probe spacecraft (SC) have their speeds increased, in the heliocentric frame of reference, by a close flyby of the earth, and other planets. However in the earth frame of reference there should be no change in the asymptotic speeds after an earth flyby, assuming the validity of Newtonian gravity, at least in these circumstances." >He also neglects to mention the fact that the energy transfer from planet >to flyby craft is effected by the direction of rotation of the planet. > >http://www.space.com/scienceastronomy/solarsystem/gravity_assist.html >http://www.nationmaster.com/encyclopedia/Gravitational-slingshot > >It seems strange for someone "expert in the field" to neglect such factors. > All the known factors have already been investigated by others so there is no need for him to look into them. The reason the anomaly exists is because there is a very small effect that cannot yet be explained by any known factor. There is quite a good article about it here. http://www.planetary.org/news/2008/0228_Researchers_Investigate_New_Cosmic.html

OK. What is a dynamical 3-space?

Reg Cahill, your hero, is not comptent to write the correct Doppler equations, a freshman task. I will not correct the errors because I like you and him to continue to make spectacles of yourselves.

Its the idea that 3 dimensional space is a physical medium that contains dynamic processes. There is a description here. Dynamical 3-Space: A Review http://arxiv.org/abs/0705.4146

The Ives-Stilwell experiment attempted to measure the doppler shift of photons emitted from fast moving hydrogen atoms. However, the hydrogen atoms would experience time dilation which would affect the frequency of the emitted photons. Now if the speed of light varies with direction, then time dilation will also vary with direction, and if these effects cancel the variable speed of light would be completely hidden. In contrast, when radar doppler shift is used to measure the speed of space craft, the radar signal is simply reflected from the spacecraft, so is immune to spacecraft time dilation effects. That difference could explain why anisotropy in the speed of light is so clearly observed in the spacecraft case. |
