Hoookay ... am I nutz, or shouldn't a physical object with the shape of an inverted catenary (2D or 3D) fall and land with the rounded side down? And shouldn't such a "catenary fall" (if 3D objects) produce a flat-ish, unstable surface that would be [ahem] very interesting to drive (or walk or yada) on, and on which square tires would be useless? 2605:59C8:160:DB08:216D:5149:ACEB:AD1C 03:42, 4 December 2025 (UTC)

A caternary curve is that of a tethered chain hanging loose in gravity, so defined as one with the curve pointed downward. this requires its inversion to curve up. Semantics, but in this case important ones.
