What Could Cause the Earth's Rotation to Dramatically Slow Down?

[QUOTE="jbriggs444, post: 6861309, member: 422467"] I am not sure that I follow what you are saying. Yes, the sun's tidal effect will slow the earth's rotation -- slower than 47 [modern] days per rotation. If the moon's orbital period is unchanged, this means that the moon is now orbitting too fast for the rotating earth. [B]This puts the tidal brakes on the moon's orbit, draining energy.[/B] The moon will not be rising to a higher, slower orbit to keep pace with the slowed earth. It will be falling to a lower, faster orbit, speeding ahead of the tidal bulges that it is producing and continuing to brake as it speeds ever faster. [/QUOTE]
