minus-squareOutsizedWalrus@lemmy.worldlinkfedilinkarrow-up0arrow-down1·3 months agoBy 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.
