“how much energy is required to rotate a mass such as the moon?”
A whole lot to change its angular velocity! Zero to let it keep rotating at the same speed it currently is.
“if the moon always faces the earth how the heck can it be that it keeps getting exactly the correct amount of energy from somewhere and changes its path each second so that it faces us?”
The same way the earth gets exactly the correct amount of energy from somewhere and changes its path each second so that you face the sun every morning? The correct amount is zero.
“these things disturb me. not that its abnormal for me to be disturbed.”
Stay disturbed. Better than being asleep.
