I don't understand how light waves can propagate through space when there is no medium? Sound waves cannot travel through space because of this. I guess sound waves are more "mechanical" and need a physical substance to travel through.

Light is a ray of photons. Photons are emitted by something and travel at the speed of 186,000 Miles per second until they strike something. They (the photons) travel quite well through the emptiness of a vacuum and are only stopped by dust, larger particles of matter, or larger objects which get into their path.

Sound is physical energy traveling through a medium in waves of vibration. In space you have a vacuum (no atmosphere), so there is nothing to pass along the energy wave.

Space is the medium that conducts light.
People often look at space as nothing.
Space is the precursor of the universe and us.
Space can accommodate any type of electro-magnetic radiation but sound needs a medium like air or rock or water etc.

Light is a particle wave which demonstrates some of the qualities of a particle and some of the qualities of a wave.

If you ever figure it out, you can be the next Einstein
