>>12889133>The pythagorean theorem probably is still there when measuring time. It's disappearance is probably due to some oddball axis we're not taking into account.What do you mean "disappearance"? Lorentzian geometry is the geometry where the pythagorean theorem has a minus sign, and perpendicular lines don't look perpendicular, but have the same slope relative to the 45-degree line (on opposite sides), where the distinguished 45-degree line is the light ray. That's the definition.
