    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.
