(I realize you are making fun of the headline, John.) There is a tiny bit of logic in that statement but it is egregiously inaccurate.

IF the heliocentric model is correct:

The Earth is mostly a closed system where nearly no matter (asteroids impacting or atmosphere being ejected) is added or subtracted; therefore the mass does not change.

The Earth 'floats' in space and does not have 'weight'. It has mass.

In theory, if mass were to be redistributed from the poles to the equator; it could slow the rotation (like a figure skater opening her arms and extending a leg to stop her spin). In practice the water would distribute equally at all latitudes making the redistribution much less impactful.

What it completely fails to account for is WHY does the Earth spin?

The Earth is an electric motor and geomagnetic jerks (changes in rotation speed) are caused by the magnetic fields it encounters as it is traveling through space.

All that is IF the heliocentric model is tr
