If the Sun were the center of the universe...
I sense a disturbance in the force... it might be a false premise.
... then we would expect to see a difference in the speed of light through the ether depending on which side of the Sun the Earth was on.
1. There is no such thing as the "ether".
2. The speed of light is independent of all reference frames, moving or otherwise. It remains the same at all times.
3. Explain to us why the speed of light would change on either side of the sun if it was "in the centre of the universe"?
Since we see no difference in the speed of light at any time of year, we have to conclude that the Earth is at the center, not the Sun.
No. The only thing we have to conclude is that it makes absolutely no difference where we are in relation to the sun. The speed of light remains the same in all reference frames. Relativity clearly states this and gives practical examples. The only thing that matters is the speed between two [or more] reference frames and that still does not, in any way, change the speed of light as measured in ANY of the reference frames.
This puzzling fact was used by Einstein in his development of special relativity.
No it wasn't. I suggest you read the proper version of relativity and not the fundie edition.
SR is complex though, so Occam's Razor suggests that the better interpretation is that we are at the center.
Relativity is a mathematical explanation of gravity and how it affects velocity and the perceived flow of time. In conceptual terms it is extremely simple, so your incredulous take on it isn't really worth anything.
This does away with the need for SR.
Given that pretty much everything in your post is false, I suggest that we just do away with you. After all, as far as Occam's Razor goes, this is clearly the simpler solution.
QED, bitch.
