Standing on the earth you experience a certain weight. In space "standing" on a platform you would experience no weight unless the platform were being accelerated toward you at a rate of about 32 ft. per second per second then you would experience a weight very similar to the weight you experience on the earth. On the Earth the weight is being generated by gravity. In space the weight is being generated by acceleration which is to say the continuous imparting of motion to the platform under your feet and through it to yourself. There is apparently a relationship between motion and gravity. Understanding this relationship is a key to understanding the exact nature of gravity.
Motion in any system of unrestrained objects will result in an expansion of the space occupied by the objects until interaction between the objects is no longer possible and the system dissipates. Unless the expansion of that space is restricted in some waythe distances between the objects will continue to expand forever. You can demonstrate this by drawing a circle on a piece of paper and drawing a few objects in it. (figure1.)
Next assign eachobject a random basic motion (all basic motion tends to be straight line motion) and draw an arrow from it to show the direction it is taking. (Figure 2.)
