The moon sometimes appear big because IT IS BIG!
It is a scientific fact that the moon is sometimes bigger and
at other times smaller. Why, might you ask? Well, you might ask,
but I may not tell. Oh, yes, I will tell.
The moon is actually made of a substance similar
to Flubber, which expands and contracts in accordance to the sunlight
that either hits it or does not hit it, leaving it in the cold
shadows. This moon substance's technical name is gouder rockulus
and has premiere powers of expansion and contraction not known
here on earth.
For instance, when you are carrying moonbeams home
in a jar, you're actually carrying tiny particles of gouder
rockulus that have penetrated the glass silicate atoms of
So, let's recap: Sun hits gouder rockulus
and moon expands and appears bigger in sky. Moon creeps behind
earth and hides in shadow and gouder rockulus contracts
and appears smaller in sky.
This is why the moon landing was such a technological
feat in the 1960's. The calculations for targeting the moon had
to be when it was at its greatest expanse. Otherwise, the astronauts
would have ended up in the cheddarus rockulus of Mars.
