195) “Astronomers say the magical magnetism of gravity is what keeps all the oceans of the world stuck to the ball-Earth. They claim that because the Earth is so massive, by virtue of this mass it creates a magic force able to hold people, oceans and atmosphere tightly clung to the underside of the spinning ball. Unfortunately, however, they cannot provide any practical example of this on a scale smaller than the planetary. A spinning wet tennis ball, for instance, has the exact opposite effect of the supposed ball-Earth! Any water poured over it simply falls off the sides, and giving it a spin results in water flying off 360 degrees like a dog shaking after a bath. Astronomers concede the wet tennis ball example displays the opposite effect of their supposed ball-Earth, but claim that at some unknown mass, the magic adhesive properties of gravity suddenly kick in allowing the spinning wet tennis ball-Earth to keep every drop of “gravitized” water stuck to the surface. When such an unproven theory goes against all experiments, experience and common sense, it is high time to drop the theory.”


OK, it seems Mr Dubay is trying to get as many mistakes into one passage as he can.

• Magnetism and gravity are quite different forces.

• As usual Dubay uses the word 'magical' for anything he doesn't understand and doesn't like. Not an argument.

• 'Gravitized' is a word that he seems to have made up. It's meaningless. All matter exerts a gravitational force in proportion to it's mass.

If you wet a tennis ball and then attach it to a drill, spin it at 1,000 rpm, what would happen? Most of the water would fly off, of course! But so what? That is in no way the same case as the earth.

There are at least two enormous differences;

1. A tennis ball has very little mass compared to the whole earth, and gravitational attraction is proportional to mass.
2. At 1000 rpm the ball is spinning very much faster than the earth

So in Dubay’s tennis ball example the balance between inertia and gravity is vastly difference to the real situation of the earth.

 As usual, Mr Dubay doesn’t take account of numbers, degree or quantity, and doesn’t understand why that matters.

And gravity is far from unproven . For instance, there is the Cavendish experiment, replicated countless times over centuries. See Point 116
