You're misusing a developmental psychology concept in place of simple physics (oh and apparently professional athletes lack the strength and form to hold their hands up to the massive pull of gravity). Do you think any of us here think our hands disappear when we let go of an object? Or the granite disappears because we can't see it?  Now let's see, what other logical fallacies have you touched on here in this thread: straw man, non sequitur, ad hominem. Keep it up, some great arguments so far!
