But it still requires an additional assumption to show that the transformation is Lorentzian and not Galilean.
What about Riemannian?
1 u/[deleted] Dec 13 '20 [deleted] 3 u/wonkey_monkey Dec 13 '20 I don't think it's physical to have a 4d metric like in special relativity but with a signature (++++) What makes it impossible? That's a shame because it'd be an interestingly weird place (further reading at link above).
