Euclidian geometry would be the same in any universe though, as it does not depend on objective physical reality.

  It could be argued that the Euclidean plane is its own universe.

    The Euclidean plane is a conceptual model also not based on physics.

      It is based on observing (and needing to measure) plots of land. The abstraction came later. Didn't Hume already prove we cannot invent anything not related to our prior experience (which ultimate goes to the universe's natural laws we experience).

        how is general relativity related to any prior experience of the 1920s?
        • belugacat 5y ago
          Trains and clocks, mostly!
          • gmadsen 5y ago
            that is special relatively , not general

          The maths that underpin GR were developed before Einstein. Without the maths you have no ontology, no way to evaluate the truth of a scientific claim. https://en.wikipedia.org/wiki/Tullio_Levi-Civita https://en.wikipedia.org/wiki/Tullio_Levi-Civita

            the math doesn't prove anything. we didn't get experimental results until decades later

        > Didn't Hume already prove we cannot invent anything not related to our prior experience (which ultimate goes to the universe's natural laws we experience). Do you mind elaborating on this, or pointing to some resources where I can read more?

        The map is not the territory. It was always an abstraction.
