Thanks to Jack for sending me this interesting 15-minute video which looks at bodies rotating in zero-gravity.
Near the end, it goes into the discussion of whether the earth has ever physically “flipped” through its axis of rotation. I don’t think it ever has – nor will it….
Also, we do know from geological records that the earth’s magnetic field flips every few thousand years – and here’s new evidence of this phenomenon: A 40,000 year old fossilized tree that shows evidence of reversal in the tree rings.
