This should be an interesting discussion starter.
My roommates, God bless 'em, have recently mentioned something I had not been familiar with before. Actually, that is not entirely accurate. I am familiar with it, I just didn't think that anyone actually believed it anymore.
Simply put, it's the idea that Earth is the center of the solar system and the planets and sun revolve around it. This is the opposite of heliocentricity, the popularly accepted and taught system where the planets revolve around the sun.
This came about on Sunday when Keith asked me if I would order a book online for him. I told him "sure, if you pay me", to which he told me it was free. So he tells me the website: www.geocentricbible.com. I'm sure my eyebrow raised for a moment in confusion. Take a look at the site if you want more specifics (or to receive a free copy of the book), but essentially it claims to support geocentricity with the Bible.
There are problems with this theory of geocentricity, though. I summarized these points from this site I found.
Centrifugal Centripetal Force
Satellites stay in orbit around Earth because their velocity creates enough
centrifugal centripetal force to counteract the gravity of Earth. At a specific altitude above Earth, satellites will appear to be stationary since they're orbiting at the same velocity as Earth turns. If Earth were stationary (geocentric system), nothing would keep a satellite in stationary orbit like that.
Psalm 104:5: "Who laid the foundations of the earth, that it should not be removed for ever."
According to the site I listed as the source above, "removed" is translated from the Hebrew mote. According to Strong [Strong's Ref. #4131] it means: "to waver; by implication, to slip, shake, fall." It has nothing to do with being motionless, but rather steadiness in motion and permanence.
There are several other verses listed. Some that my roommates mentioned were the ones that said essentially "the sun rises and the sun sets", or in Joshua where it says God "stopped the sun". They claim that since God cannot lie, and the Bible is divinely inspired, that it must literally mean God stopped the sun. This doesn't hold water in my opinion, because it is correct to say, from our perspective on Earth, that the sun rises and sets, because that's how it appears from our perspective. Likewise, if the sun ever stopped moving, it would appear it had been stopped. Duh.
There are several other very simple, logical, and scientific reasons why geocentricism just falls apart. Such as the huge mass difference between the sun and Earth. Explain why an object with hundreds of time more mass than Earth would be held in Earth's gravitational pull?
Talk amongst yourselves.
