      Not true, as when space bends, it bends the rulers and compasses too. We experience no spatial distortion.

      A person traveling near the speed of light doesn’t feel like time is slower for them (but it is and we can measure it)

      The principle is equivalent.

      That said, it’s not a straight line in any topology standard I am aware of.

      Sure you could CREATE a topology framework where this would be considered a straight line, but there is no real world model that could come even close without so much mass being concentrated in static relative areas, and EVEN THEN it would only be straight for a predetermined instant before the mass deforming spacetime began interacting with each other.

      That’s the problem with spacetime deformations, almost no layman takes into account the ridiculous amounts of static mass to make those strange topologies.

    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

    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.

    Globists will argue that on a globe this is a straight line. Seen these arguments before, don’t work on me
