Empty space Quote by Henning Genz
““Theory and experiment both show us that light does not need a material medium for propagation. We would have no trouble understanding this if light were nothing but particles zooming along through empty space. But that is not the way it goes: Light is a vibration, an oscillation made up of elementary oscillations we call photons. But there is no substance that oscillates when light propagates; thus we cannot impede the propagation of light when we remove substances from some given space.””

Light propagates as electromagnetic waves; it does not require a physical medium, only space for its fields to oscillate.
In simple terms: Light is a wave, not a substance.
Understand light as wave phenomena.
