The Geocentrism Challenge
Anyone else find this weird?
CAI 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, we at CAI don’t think anyone CAN prove it, and thus we can offer such a generous reward. In fact, we may up the ante in the near future.
Read the full challenge here. Perhaps a signposts reader will win

It has to be a wind up, doesn’t it?

I think so, Richard. But you can never be sure

When I looked at the site, they do seem to be taking it very seriously. And not showing any sign of handing over the dosh.

The geocentric system is the best one for dealing with things on earth - we speak of the sun rising etc, and that is not considered incorrect.
The heliocentric system is the one which makes the most sense when talking about the solar system. That doesn’t mean it’s the “only viable way to understand the universe”, it’s just the only viable way to understand the physics of the solar system. Weird that the CAI made the point by setting a such a challenge.
If you’re considering a whole galaxy or more, a different frame of reference may be needed, and hypothetical aliens from elsewhere will criticize any solar system whose inhabitants think the galaxy revolves around it. And maybe the CAI will too.
I gather that the Catholic hierarchy regards many of its public statements as compulsorily true (I can’t explain this well), and this is why they are making this point.
