Based on numerous physical experiments that can easily be performed by anyone, the arrangement of different matter of varying densities which are contained in a vessel are always arranged in a particular order when a force is applied to that vessel and that vessel is put into motion. The direction of the motion dictates the density gradient orientation. Based on other experiments it is also apparent that this arrangement of matter (based on density and dependent on the direction of motion) ceases when objects are in free fall. This would imply that when objects are in free fall there is no force present that is responsible for the apparent downward motion of objects, but rather the reference frame (earth) is moving upwards to meet the objects. This concept is explored (the upwards motion of the earth) and calculations are performed to understand how we (standing on earth) can perceive a downward acceleration (g) of objects in free fall if the earth is in motion upwards. Other concepts regarding the motion of the earth are also discussed.
