This is a good post entirely, but it bothers me that you mentioned Joshua as somebody who is noted 'in recorded history' to have lengthened the day - unless it was meant as tongue-in-cheek.

I don't mind people having whatever beliefs of course, but this kind of undermines the rest of the post as a legitimate scientific source. There's of course no way that there is real recorded documentation of a day on earth being extended - though there might be some interesting phenomenon out there that gave this illusion that might be worth a look into.

Anyway, otherwise very enlightening, cheers!
