You’ve already answered this question in August 2009 but I’d like to go into more detail. This website: http://www.mastikorner.com/forum/islamic-picx/6843-miracle-prophet-muhammad-p-b-u-h.html claims that Allah split the Moon in two at the request of the Prophet Mohammed and that there is a split on the Moon documented by American scientists that goes right around it which is evidence of the miracle. Is there any truth to any of these claims?
My recommendation is to not believe everything you read on the internet. Peer-reviewed papers are the only scientifically valid sources of information out there. No current scientific evidence reports that the Moon was split into two (or more) parts and then reassembled at any point in the past.
