The Coriolis effect can be explained by the gravitomagnetic effect of the rotating heavens.
I have a few issues with this explanation.
• First of all, gravitomagnetic effects are tiny - they are only really observable on massive scales, like the space around a spinning black hole.
• Secondly, even if it did create a measurable effect, the heavens being above us would put us perpendicular to its rotation. To experience any noticeable gravitomagnetic effect we would need to be on the same rotational plane of the spinning heavens.
• Thirdly, if there was enough mass and a fast enough rotation to produce measurable gravitomagetic effects, the earth would be directly in the path of a supermassive relativistic jet, which it clearly isn't.
• Fourth, it requires an acknowledgement of general relativity, which is incompatible with Universal Acceleration.
• Fifth, the proposed mechanism does not explain the Coriolis Effect in that it would only account for a general twisting of the atmosphere around the central point - not the reversal of atmospheric vortex rotation south of the equator.
• Sixth, the Coriolis effect is not detectable when independent of the earth's rotation. Gravitomagnetic effects should still be in effect under these conditions.
• Seventh, being a relativistic effect (in that it results from the distortion of spacetime) it should have an even effect on all matter and not favour large fluid systems the way the Coriolis effect does.
• Eighth, furthermore, as the gravitomagnetic effect would be uniform across the whole earth, its effects would only be visible from a frame of reference well beyond the earth, in fact, well beyond the gravitomagnetic effects themselves, which would cover an area much larger than the earth.
Like I've said before, you can't proclaim to believe in a giant flat disc of incredible mass but no gravity accelerating infinitely upwards and then invoke Relativity when it suits you.
