Interesting post,

both energy and gravity are two myserious elements that do fuel the mind to ponder. Einstein once said in his writings that space, not so much as gravity is what defines the law. The body naturally wishes to occupy space between land and air. He designed this theory based on space where he said that if a person threw an object in space it would go downward because the object naturally tries to occupy the space or in the case gravity. In a more simplistic way of looking at this if you were to jump off a two story house and and land on your feet it is not gravity that pulled you to the ground but the natural law of your body wanting to occupy the space between the ground and air. Interesting!
