A few more links showing that the "long day of Joshua confirmed by NASA" story is false:

I happen to have a reprint of the 1890 book by Charles Totten that seems to have started off this nonsense. Put bluntly, the book is a lot nuttier than the craziest of JW publications purporting to be about science and scripture.
As for being amazed at things like "36=3+6=9", don't be. It's easy to show that for any number divisible by 9, the digits add up to a number divisible by 9. And of course, the process is repetitive, so by repeated additions of the digits you always end up with a 9. Example:
88,888,887 = 9 X 9,876,543
88,888,887: 8+8++8+8+8+8+8+7=63
63: 6+3=9
This is not magic; it's a basic property of numbers.
