Ptolemy:
Your assertion that gravity is "invisible" whilst the form of EM radiation known as "light" is visible is at best a rhetorical trick and at worst a despicable ruse.
Do you believe that the Creator supplied the creation with integrity -- i.e., the ability to be studied by cognitively-aware creatures?
If so, then it appears you've fallen into a large vat of gooblety-gook, in spite of your obvious ability at English articulation. If not, then what you're implying about the observable universe is simply frightful. I'm really trying not to be sarcastic, however --- I'm glad I'm not you.
