The earth was slowing down.

This wasn’t a new revelation by any means. Newton’s 1st Law of Motion states plainly that an object in motion will stay in motion with the same speed and direction unless acted upon by an unbalanced force.1
That force just happened to be ocean tides.2 But by the scientists' measurements, the earth’s rotation only slows about 2 milliseconds per revolution around the sun,3 not exactly a stunning figure. So what was the problem?
