Gravity.

Which is the best explanation for the earth's gravity?.... If mass was responsible for the effects of gravity, this means that a more massive object's stronger attraction to the earth's mass, would fall faster then any less massive objects, when we know that this does not happen. Because all objects have to fall at the same rate of speed regardless of their mass... Where it is actually reverse gravity (centrifugal force) that neutralizes gravity's acceleration on an object, causing all objects to fall at the same rate of speed, regardless of their mass (which better conforms with experiments)... Whenever we are in a fast traveling vehicle and it changes its direction of travel, we always experience a force. This is why we experience a force with centrifugal force because its rotation is "a constant change of direction", which creates a constant force (reverse gravity).
