Hi Tangle
Perhaps we could have a shot at putting a list together of stuff that no longer works if the YEC world view is right. (Maybe it's been done before, if so, please point me at it.)
All.
But I could be wrong ... eventually the scientific method would seem to come into conflict with unevidenced beliefs -- it would be necessary for a YEC to make claims of which science/s they accept without question.
Mind you scientists should have trouble making such a claim.
Enjoy.
