Question...
1) If the earth is expanding, is it because its mass is increasing?
2) If so, then why is the moon receding from the earth?
If the mass is increasing then the gravitation constant should be going up, thus the gravitation pull on the moon should increase and the moon should be getting closer.
or....
Alternatively...
The earth is expanding because it is like a loaf of bread... there's yeast at the core and we are still in the rising stage of earth evolution. When the sun reaches the Red Giant stage, we will be in the "baking" stage by where our crust will be nice and golden brown...
BTW: The moon is made of Cheese.
Thus, the new binary system will be known as "Fondue"
OIC!
