A:
Great question. Light doesn't travel exactly in straight lines. It's a wave. llke ripples on a pond. So that's how it spreads. If the wave is already very spread out compared to the size of the ripples, then the growing spread may not be very noticeable, so it seems to travel in a straight line.
