I must've missed the bendy light thing. It's giving the feel of an inside joke now.
It's Parsifal hypothesis on why the earth looks curved, light under the clouds, solar neutrinos, and sunrise sunset. Its considered a joke by some people, because there is not physics, math, or experimental evidence to back it up, but he believes it and so do a few of the members of FES
You might have just started bendy magnetic fields: some unknown force takes the fields, and makes them bent to your flat earth diagram from the first page
I have a question tho, how do we know the shape of the field lines? most compasses I know only point in the x,y directions, not z. while this does determine gradient, it doesn't say how steep it is.
