Catholic Apologetcs International will write a check for $1,000 to the first person who can prove that the earth revolves around the sun. (If you lose, then we ask that you make a donation to the apostolate of CAI). Obviously, they at CAI don't think anyone CAN prove it, and thus they can offer such a generous reward.
"Now a word of caution. By "proof" we mean that your explanations must be direct, observable, physical, natural, repeatable, unambiguous and comprehensive. We don't want hearsay, popular opinion, "expert" testimony, majority vote, personal conviction, organizational rulings, superficial analogies, appeals to "simplicity," "apologies" to Galileo, or any other indirect means of persuasion which do not qualify as scientific proof."
Seems to me that nothing actually revolves around any fixed point in the universe and that the motion of objects is relative to the observer.. Anyone to claim to $1,000?
