    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).

        they do tavel in a perfectly straight line though.

        space time is curved, not the light path.

          I don’t think that’s right because they are affected by gravity, even if ever so slightly

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            Newtonian gravity has been replaced by General relativity, and has been proven to be the correct model (at least more correct than Newtonian gravity).

          What about the fact that light bends around corners? Notably the interference pattern when shining light through a slit?

            Stop being mean to light by making it choose what slits to go through.

            it has choice anxiety.

              Ah, sorry for the confusion, I was referring to the single-slit experiment, I wasn’t giving light a choice.

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

              Sound waves are compressive waves, they radiate spherically (in principle, turbulence in the medium is going to make them slightly irregular)

        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.

      I work in public education. That’s a pretty innocuous statement compared to some of the shit I’ve heard. Some teachers get so complacent in their lessons that they forget to apply it in their critical-thinking. Then, they have some crazy logical lapse, say something ridiculous out loud, and then some other kid from that class repeats that same shit to their own students when they grow up. These are mistakes that could easily be rectified with an apology or deliberate correction, but teachers are pushed so hard to prioritize being an authority figure that they sometimes forget to just be a teacher.
