I can't make heads or tails out of it -- I can't find any reference to such a phenomenon called "bias" and I don't see how gravitational field variations (I assume he means the ones caused by uneven density) could have any effect at their minuscule amplitude. Is this a result of some misunderstanding or am I missing something?
Thanks. I didn't know that the differences change in space in such weird fashion. I guess what was meant were spatial differences, not temporal ones and it now the part about magnetic field makes some sense to me.
