Did God forgot that the moon would crash into the earth if stopped in it's orbit ?

Joshua 10:12-14 states that both the sun and the moon appeared to ‘stand still’, giving Joshua enough time to complete the battle and so to defeat the Amorites. Verse 13 says this was recorded in the Book of Jashar, an ancient source for the writer of Joshua. It was well known in ancient Israel but has not survived as a separate document. However, some suggest that it spoke of the summer solstice, so the account meant June 21. The word 'solstice' comes from the Latin 'sol' (sun) and 'sistere' (to stand still). Every summer solstice the sun appears to rise over the same spot for about a week. Then there's "the land of the midnight sun" where in mid summer the sun almost never sets. Did God do something with the Earth's axis for a brief time? The Bible indicates that something supernatural happened.

Some people link it with another supernatural account in 2 Kings 20:9-11 when the sun’s shadow went back ten steps (either on a sundial or on steps) to prove to King Hezekiah that God would heal him. Well, a Mr Harold Hill used to preach about this in his lay-sermons. He said that when he was working for Nasa in the 1960s, calculations of planets were being made in connection with spacecraft trajectories. They hit a wall – there seemed to be a day missing from the calculations! This was pondered, when someone recalled Joshua 10. But it wasn’t a full 24 hours that was ‘lost’ by the computers – it was 23 hours and 20 minutes. Then someone remembered 2 Kings 20 and suggested that if the sun appeared to move backwards 10 degrees, that would be an arc of 40 minutes. (But the KJV has steps, and not degrees.)

Nasa disputes the explanation, however .They agree that Mr Hill did maintenance work on one of its diesel engines but said he could not have been party to the calculations. The Nasa Public Affairs office in Washington says, “There is no truth to the recurring story that Nasa uncovered a lost day.”

But here's an intriguing point. The sun and moon were two of Canaan's most powerful gods, and they proved powerless against Jehovah. Joshua and his troops traveled all night from Gilgal and took the Amorite armies by surprise, so the moon 'helped' them - not the Amorites who worshiped the moon! Likewise the day of chasing them resulted in the sun 'helping' them - not the Amorites. I lean towards this combining with a miraculous "land of the midnight sun" event where it never normally occurs. AiH

If he can make it then he definitely can mend it. Working outside the laws of physics is one of the reasons that set him apart as God.

God created the Universe and set the laws, so it is obvious that He can alter them if He wishes.
