The Theory of Gravity, like the Theory of Evolution, has not been “proven.” Now there are some who, like those who counter evolution with “Intelligent Design,” counter gravity with the Theory of Intelligent Falling.
“Gravity–which is taught to our children as a law–is founded on great gaps in understanding. The laws predict the mutual force between all bodies of mass, but they cannot explain that force. Isaac Newton himself said, ‘I suspect that my theories may all depend upon a force for which philosophers have searched all of nature in vain.’ Of course, he is alluding to a higher power.”
The last quote of the article is priceless. Just keep in mind the source of the story.
