I can observe "gravity" by watching a rock fall back in my hand after I throw it in the air. At least it has some basis because I can see it.

I'll buy into the 'degree' thing but you only know that when a ball falls back into your hand it's gravity at work because someone told you it was, right?
What do you really know about gravity at a theoretical level?
