The list below is believed complete, though membership – like everything here – is subject to revision.

  • Tycho Brahe – Danish astronomer (1546–1601) whose geo-heliocentric system kept the Earth central while agreeing with the sky exactly – the Concordant Orrery's trick, three centuries early.
  • Geocentrism – The doctrines that decline the motion of the Earth, holding it fixed at the centre of things.
  • Kinematic and dynamic equivalence – Two claims about reference frames: the first true and never disputed, the second contested, the two offered as one.
  • Ptolemy – Alexandrian astronomer (c. 100–170 AD) whose Earth-centred cosmos held for 1,400 years – its central Earth, to his admirers' inconvenience, a sphere.
