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.
