I see you're confused; I never claimed to be a scientist, not once. I am an analytical chemist by trade, and that is not a scientist, so I hope that's cleared that up for you. Also, I have not defined acceleration anywhere, perhaps you're mixing me up with someone else. And finally, I didn't suggest that a scientist hadn't thought of the halbach array, as they clearly have, my point was that a modern physicist, someone who studies earths magnetism as part of their position, would surely have noticed that the earth’s magnetic field was comprised of a special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to the rear? that nature had somehow managed to arrange in exactly the fashion as required to get around the FE hypothesis on magnetic poles, and that the idea wasn’t just one produced by a random internet forum user?
I hope you're suitably enlightened.
