Do you have links to places where the proofs of Euclidean plane and space are?
Are there proofs for gaussian or Reimanian spaces or planes?
Anyway, if nature doesn't have 4 spacial dimension, thing which should be thought always, until a proof of the opppsoite is done, why do we need a proof for 4d Euclidean space? |
