      According to classical theory light waves require a medium for their propagation. The medium for the light waves is named as ether. So, in other words light cannot travel in a vacuum. Michelson and Morley did perform an experiment and proved that ether does not exist. In other words light waves do not need a medium to travel. So, according to the concept of Michelson and Morley light can travel in a vacuum.
