Hello,
I'm currenltly engaged in a debate - primarily with young-earth creationists (YECs) - about modern geocentrism. They are defending the position of Gerardus Bouw. I need some help from anyone out there who has expertise in orbits or in this debate in particular.
Bouw's website is here:
Geocentricity
http://www.geocentricity.com"
The basic argument is that because general relativity (GR) is based on relative motion, then it is as valid to adopt the geocentric frame of reference as it is to adopt the helocentric (or acentric) one.
Bouw's site, and my opponents, specifically use this quotation from Einstein to support their claim that the Earth is fixed and non-rotating:
I remember a good set of rebuttals to these claims at a website called Catholic Outlook, run by Gary Hoge. The rebuttals show how satellite ground tracks make the geocentric argument hard to defend. The Internet archive has links here:
Catholic Outlook: Topics: Geocentrism
http://web.archive.org/web/20040803175044/catholicoutlook.com/geocentrism.php"
In addition to presenting Hoge's side, my basic response has been that if GR supports either coordinate system with equal justification, then neither can be chosen as the real or true coordinate system, so how is this a win for geocentrism. Their response is that even a draw is a win for geocentrism because most modern people think that geocentrism "lost" centuries ago. They also further propose something called "GR+", a new system with exactly one favored reference frame - the static earth.
I am having some trouble pinning down my opponents on some of the issues involved, such as what "fixed" means in the context of a static Earth (does it appear at rest from all reference frames, and how is that even possible?), how the motions of geostationary satellites (see Hoge) are explained in geocentrism, and so on.
I'm not a math or physics expert but would be willing to do or learn some math if it will help with my argument. I just need to know what would be most effective (short of learning the math of GR in a short timespan - I know that is too tall an order).
There is also a good set of user comments posted at this link, in which one of the commenters presents several critical questions about the geocentric argument. One of the best is about the Solar and Heliospheric Observatory (SOHO) satellite:

Several other good questions are asked by this user on that page, but I don't want to make this initial post too long, so I will post them later if needed. Also, I find some of this tricky, because Bouw's argument assumes that the entire universe is rotating around the Earth once per day (which must account for the Earth's yearly orbit as well as its daily rotation), somehow carrying the entire contents of the universe with it (embedded in quantum foam so that the bodies beyond Jupiter don't have to move faster than light). That may sound crazy to some, but I want to know of any point-by-point physics or logical refutations of this argument if any exist.
I think Bouw appeals to Mach's principle, so I want to know whether Bouw is actually wrong on the physics and if so, why is he wrong. One thing I have not been able to get out of my opponents is, if the Earth is made of the same elements as the other bodies in the solar system, why does it remain fixed while the other bodies are carried around embedded in the quantum foam? How can the Earth resist the same forces if it is made of the same stuff?
I understand that some may think this argument is a pointless waste of time, but that's why I posted this topic to the debunking area. Presumably, people here are more willing to engage in debates that others think are pointless. I will bring my debate with the YECs to a close, though, if there really is no way of proving that the modern geocentric argument is wrong. But I suspect that there is a flaw, either in the physics or in the logic, of the arguments of my YEC opponents, and I do not want to end my side of the debate if I have a chance of winning it. And the last thing I want to do is back myself into a corner trying to refute something that may actually be true, or at least mathematically acceptable.
I'm happy to provide more detail on the arguments if necessary. That includes quoting or summarizing Gerardus Bouw's arguments for modern geocentrism, which I think are the ones that YECs consider the strongest. (Some of you may not want to ready his 160-page book on the topic.)
Thanks in advance for any help.

The struggle, so violent in the early days of science, between the views of Ptolemy and Copernicus would then be quite meaningless. Either CS could be used with equal justification. The two sentences, 'the sun is at rest and the Earth moves,' or 'the sun moves and the Earth is at rest,' would simply mean two different conventions concerning two different CS.

The Earth and Soho are like 2 carousel horses next to each other, from the point of the view of someone sat on the outer one the inner one doesn't move but both move from the point of view of the man stood in the middle of the carousel.
Since Soho doesn't move from the point of view of its controllers then the Earth must be the outer horse not the man in the centre.
