    I can’t quite get over the fact that the premise is false

      no science teacher would ever say that.

      Light travels in a straight line, plenty of crystals, linear erosion, many trees evolved to be as straight as possible…

      and to be esoteric, every object path, even when gravity affects them (they travel in a perfectly straight line, but it is spacetime that is curved).

        Careful with those absolute statements there buddy. I was told the same by a teacher, who challenged the class to come up with natural examples of either straight lines or perfect circles. He talked about how such things cannot exist because at high enough resolution/magnification there will always be interruptions.

        Your own example of light traveling in straight lines doesn’t account for the fact that photons are waves and absolutely do not travel in straight lines.

          they do tavel in a perfectly straight line though.

          space time is curved, not the light path.

              But isn’t the gravity bending the space, so the light itself is travelling straight but seems curved to the observer?

                Hmm, I’m not actually sure. Are we also ignoring refraction and reflection because the path is straight between those? If we’re talking discrete photons, you may be correct about each segment in its path being perfectly straight, but I’m not a theoretical physicist.

              gravity isn’t a force, it’s the curvature of space-time itself.

              light follows a perfectly straight line through vacuum. the space itself isn’t straight.

              like drawing a straight line on a flat paper, if you roll the paper, that line is still straight within it’s medium.

              Newtonian gravity has been replaced by General relativity, and has been proven to be the correct model (at least more correct than Newtonian gravity).

          Photons are both particles and waves, not only waves (that’s because of the wave-particle duality discovered by/after Einstein’s theories).

          It travels in a straight line, just not in every dimension. Look at a waveform from above, it’s a straight line.

          if by straight you mean a perfect eucledian line, then there’s no such thing as a perfect line in nature or reality.

          as that might violate the Eisenberg Uncertainty principle. because if I know two points position or or if I know the direction and one point I’ll know the position and direction of every point.

          but then that’s too esoteric.

      It’s useful as a navigational aid, if you’re lost in the woods keeping an eye open for straight lines, especially horizontal, is a good way of finding man made structures and potentially a way out. Beyond that, on a micro scale nature loves perfect geometry.

    Most scientists won’t say that there are no straight lines in nature, it’s so obviously and provably wrong. I think it’s more of a thing philosophically said when talking about how modern life is so different and unnatural compared to the lives of ancient people or animals.
