This past week's Jewish Press had a letter from Amnon Goldberg, of Sefad, Israel, advocating geocentrism as the Torah-true view of cosmology. He relies on Mach's Principle (something that has never been fully accepted by the scientific community) to make the point. He states:
Mach’s Principle shows that a universe going around the Earth every 24 hours will produce exactly the same effects as Foucault’s Pendulum, Coriolis forces, earth bulge, weather patterns etc., as an Earth rotating in its axis every 24 hours.
Now, I'm not going to claim that I fully understand Mach's Principle, but one of the main problems I have with it is this:
The Andromeda Galaxy is the closest galaxy to the Milky Way. It lies aproximately 2.5 million light-years away from us. If one maintains that the entire universe rotates around the earth every day, that means that the Andromeda Galaxy would speed along, making a 15.7 million light-year journey every day (circumference = pi * diameter)*. That results in a speed *much* faster than the speed of light. And objects that are even further away would have to travel even faster to make it around the earth every day. To me, a rotating earth sounds much more reasonable.
(*Yes, I know the path that the galaxy would take would be an elipse and not a circle -- I just used the formula for the circumference of a circle as an approximation.)
