These are The Undeniable Facts:

1)   A relativist can only say that Earth is in relative motion. If you say something, such as the Earth, is definitely in motion, then you are in violation of relativity.
2)   We, the observers on Earth, are at the center of our own observable universe. This is what the empirical evidence says. Both relativists and absolute Geocentrists acknowledge this.
3)   Absolute Geocentrists say that our (we, the observers on Earth) observable universe is all that there is to the universe. There is nothing beyond our observable universe.
4)   If our own observable universe is the entire universe, and we are at the center of it, the Earth can be empirically shown (interferometer experiments) to be at absolute rest. Therefore if our own observable universe is all that there is, Earth is immobile at the center of the universe.
5)   According to standard Big Bang theory, anything beyond our (we, the observers on Earth) observable universe will be forever unobservable to us due to the expansion of space.
6)   Things that are unobservable do not exist as far as science is concerned. Therefore anything beyond our observable universe does not exist as far as science is concerned. How could it, since the ability to observe something is a requirement of the scientific method?
7)   If 4) is correct then relativity is false, because Earth is a preferred, special reference frame, defining an absolute rest frame.
8)   The only way 4) can be false is if there is a larger universe beyond our (we, the observers on Earth) observable universe.
9)   Therefore, both relativity and the Copernican principle require the existence of a universe beyond our observable universe, i.e. both require something that is beyond the scope of the scientific method and rational scientific inquiry.
10)  Mainstream science claims that there is a larger universe beyond our observable universe. They MUST claim this, because both relativity and the Copernican principle require it (see 9)) Google “the observable universe vs. the entire universe.”
11)  Relativity is presented to the public as scientific fact.
12)  Therefore, relativity is pseudo-science.
13)  The only options available to us are absolute Geocentrism or relativistic geocentrism.
14)  Relativity is a pseudo-science, therefore the only option available to strict adherents to science is absolute Geocentrism.

Earth is at absolute rest at the center of the universe as far as science is concerned. Relativists are the kooks, not the Geocentrists. Case closed, class dismissed.
