If light did not travel in a straight line?

Answer 1

Light is a particle that acts like a wave and therefore does not travel in a straight line. light has nothing to do with gravity, the fourth dimension or the 'fabric' of space time.

Answer 2

If light did not travel in a straight line, optical devices like cameras and telescopes would not work as effectively, as they rely on light rays traveling in straight paths. Communication through fiber optics would also be affected, as the signals wouldn't reach their intended destinations accurately. Understanding and predicting the behavior of light would become more challenging in fields such as physics and engineering.

Answer 3

if light did not travel in a straight line there would be no shadows as the photons would simply move around the obstruction and strike the ground.
