   How can light (or electromagnetic radiation) travel through a vacuum when there is nothing there to act as a medium, and do so forever in all directions? For example the light coming from a star millions of light years away.

   Can light travel through a vacuum without a medium?

   • Light may seem to be an exception, leading many to say that light is a wave that can travel through a vacuum with no medium. Light doesn't use EM fields as its medium; light IS an EM (electromagnetic) wave.

   Can light waves propagate through a vacuum?

   • Still the fields are there! Therefore, just as a matter wave (which is nothing but a particle), light waves, i.e. waves in the electromagnetic field, can propagate through such a "perfect vacuum". Vacuum fluctuations or quantum mechanics has nothing to do with it. This is true, even in purely classical electromagnetism.

   How do light waves travel?

   • Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium to pass through, they can travel through a vacuum. Light from the Sun reaches Earth through the vacuum of space. A short video explaining the concept of light waves.

   Do particles propagate in vacuum?

   • Particles do propagate in vacuum after all . Without getting into the wild discussion on the intricacies of what may be meant by a perfect vacuum, all waves may be thought of as requiring a medium. Light may seem to be an exception, leading many to say that light is a wave that can travel through a vacuum with no medium.

   Does light travel Throug wood?

   • While this is true, it neglects the wave side of things, and that light travels almost the same through things besides a vacuum, such as glass. This train of thought tends to forget the big picture. (Not the downvoter.) On the other hand, light does not travel throug wood.

   Can light travel faster than sound?

   • Not even Superman managed that. In fact, nothing can travel faster than the speed of light. By comparison, sound travels just 340 m in one second, about the length of three and a half hockey pitches. The table summarises some similarities and differences between light waves and sound waves:
