In our universe, is the shortest distance between two points a straight line or a hyperbolic curve? (I'm debating this with my teacher)(adsbygoogle = window.adsbygoogle || []).push({});

Of course you're going to ask me for the definition of a straight line but I don't think I can define that relative to a curved line without getting unnecessarily rigorous, so just use the definition of a straight line that you would use synonymously with "a curve that has a constant slope."

Don't pick apart my definition and just answer me this quick one!
