(It is simply too heavy to fall.)
Why doesn't the moon fall is a question which has buffled ancient sky gazers ever since time immemorial.
Before modern astronomy, the moon was possibly thought to be made in china (made of china) and holding to a firmament on which it slid it's way along.
However, the advance in astronomy eventually confirmed thatthe moon was a form of a world.
In a normal reasoning one would still wonder why doesn't it fall then?.
A simple reasoning would answer that a moon orbits instead of falling.
Nevertheless, the true answer to the question of falling has gravitational analytical point.
The infamous scientist Galileo Galilee proved through his experiment at the leaning tower of Pisa that falling objects of different masses fall at the same rate.
Galileo's deduction was completely correct based on his factual observations.
However, in some gravitational principles of 'The General Theory Of Gravitational Dynamics And Life', objects are shown to have repelling properties on one another when both are of a particular large mass.
Big heavenly objects as a result of these principles exert gravitational force on one another each pulling the other body to fall on it, when far. But on getting close to some distance, again, they repel away as their gravitational charge concerts to positive.
For this reason, the moon repells away where is supposed to fall.
This means big heavenly bodies refuse to fall.
They are simply too heavy to fall.
