Once again, simply stating that gravity is a scientific theory does not devalue the value of its acceptance, implementation, observation, and measurement. In fact, the theory of gravity has millions and millions of supporters the world over again. Your "theory" is failing to take flight in a stoner forum. Well done champ.
You should learn the basic tenants of most sciences accepted around the world. Earth Science, Biology, Chemistry, Physics, maybe get fancy and pick up some Bio-Chemistry or Organic Chemistry. At any rate, the basics of science. If you wish to make sound arguments in science ( also known as the science of argumentation just in case your mind is wondering) you have to speak the language.
"G-force" is NOT a MEASUREMENT
G-force IS A UNIT OF MEASUREMENT
Acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities. Acceleration is the CAPACITY to gain speed.
I may be mistaken, but you should touch on some of this type of coursework in your freshmen year of junior college....depending on how bad you place during your placement exams.
