Actually, smart guy, I was well aware that gravity is not constant throughout the universe, and, in fact, it varies on the Earth's surface as well. It was required learning in high school physics, as well as necessary to persue a Mechanical Engineering degree from a top rated school. Now would like like to continue your parading or would you rather just take the friendly jabs "like a man" (no offense to the female readers out there). If you choose the former may I suggest that we change the subject to thermodynamics, fluid mechanics, micro/macro-economics, material strength theory, or maybe system dynamics...as my physics are a bit rusty. If you choose the latter, you will realize that we have never met, and as such we are not your friends (yet) that may be able to decypher your quickly typed messages, and cannot properly infer your tone or ideas from the unfinished, and difficult to read, thoughts that you type. A little bit of grammer goes a long way towards communicating your ideas...that is, after all, what it is for.
