Hi Wizofoz,
why is there also a high tide on the OPPOSITE side of the Earth to the moon?
Would you agree it's because the earth and moon orbit one another about their common c of g? Since that point is not at the centre of the earth (must be somewhere say about 1/10? distance to the moon), then there is a high tide on earth's moon side (due closer to moon) and another on the far side because it's "centrifuged" out.
