But the days will get shorter.
If there's weren't other forces at play, but the tidal forces are slowing the Earth's rotation down. Eventually the same side of the Earth will always face the moon, just as we have already locked the moon's rotation to it's orbit about the Earth.

Actually, it does. The nuclear fission reactions in the core cause the loss of about 16 metric tons of mass every year.
Yeah... I had forgotten about that ... imagine that, 16 metric tons of mass converted into pure energy each year here on earth!

All gravitational orbits and spins are increasing. The gravitational constant is not constant. It's decaying. Because density is decreasing. Gravity is not fundamental....it depends on density. The weakest force is a by-product of an electrical asymmetric particle bond.

Apparently (!) it is a lot weirder than that. How about up and down following a 5.9 year sine wave?
