According to various sources, the Moon is separating from Earth 4 cm every year. I’ve searched for the explanation and I’ve found the following:
The friction the seas and oceans from the Earth make with it’s soil causes the Earth’s rotation to slow down. This causes the Moon to speed up because of Newton’s law of action and reaction. Due to this acceleration, the Moon experiences a centrifugal force making it move apart from Earth.
My question is the following: Why does the Moon move apart from Earth according to Einstein’s model of gravity? If mass and energy curve the fabric of space time, does it not mean that the Moon is only rotating Earth because of this deformation and not because of any force acting on it?
