... One example of a non-explosion powered 'expansion' is Lunar Recession:
Friction by the tides is slowing the earth's rotation, so the lenght of a day is increasing by 0.002 seconds per century. This means that the earth is losing angular momentum. The law of conservation of angular momentum says that the angular momentum the earth loses must be gained by the moon. Thus, the moon is slowly receding from the earth at about 12 inches 3.82 centimeters per year.

There fixed it. All better now.

You are indeed more correct than my source!

It claims “4 cm (12 inches) per year”....

But according to Google: 4 centimeters = 1.57480315 inches.
(But 12 centimeters = 4.72440945 inches.)

So it looks like somebody got their numbers swapped.

Thanks for the heads up, dread78645.
