    Low IQ: it’s not a straight line

    Medium IQ: it’s a geodesic on a sphere, so it is a straight line

    High IQ: it’s not a straight line

            In actual reality there would be wind and water currents diverting any ship sailing that route from the depicted “line” anyway so the whole argument is pointless

            The only straight line paths in the universe are followed by electrostatically uncharged non-accelerating objects in free fall in a vacuum. Or massless particles.

    THAT would be one god damn brutal sail. Both horns, Southern Atlantic crossing followed up by the Indian Ocean.

    The range of foulies you would need to bring would be 3/4 of your pack. Foulies underwear and A sock (you’re going to lose one anyways)

      By defining the coordinate system as a sphere.

      Basically, there are multiple right answers, but the most correct answer depends on how you define coordinates.

      In “simple”, xyz it’s not a line.

      In Euclidean geometry, a straight line can follow a curved surface.

      In bullshit physics, everything is warped relative to spacetime so anything can or cannot be a line, but we won’t know.
