We can't SEE gravity....but we see its affects....
We can HEAR gravity....but we see its affects....
We don't speak to gravity....though on earth, it is faithfully there...
Gravity has its own laws of physics....and to break them, we think 'freedom'....
We obviously live within the properties of gravity....but...most cannot explain it...

... the same can be said of God, but many of those who proclaim gravity, deny the existence of God.

Go figure!!
