In this blog, the author assumed that the similar gravitational effect created by a centrifuge used to train astronauts, is the same as to the earth's gravity, giving a rather unconventional proposal that the Earth's surface itself is expanding in a rate of 9.8meters per second per second from its center creating a constant rectilinear acceleration to provide a similar effect as to the centrifuge, the difference is that the centrifugal force is the rotational version of gravity.
If this is true and gravity is not attractive then how could the sun and the moon effect the ocean tides here on earth?
