““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.””
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
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.
