#  LIGHT AS AN EXCITATION OF SPACE Let's try and understand…

![“LIGHT AS AN EXCITATION OF SPACE Let's try and understand light in terms of an excitation of empty space-even if that makes no immediate sense. We might alternatively understand light in terms of a field, as we introduced that term in chapter 2. But light differs from the fields of temperature…” quote by Henning Genz](https://sms4smile.com/quotes/i/69a/henning-genz-4557_empty-space_light-as-an-excitation-of-space-let-s-tr_1993735.jpg)   [Download](https://sms4smile.com/quotes/i/69a/henning-genz-4557_empty-space_light-as-an-excitation-of-space-let-s-tr_1993735.jpg) [Open image](https://sms4smile.com/quotes/i/69a/henning-genz-4557_empty-space_light-as-an-excitation-of-space-let-s-tr_1993735.jpg)

> ““LIGHT AS AN EXCITATION OF SPACE Let's try and understand light in terms of an excitation of empty space-even if that makes no immediate sense. We might alternatively understand light in terms of a field, as we introduced that term in chapter 2. But light differs from the fields of temperature distributions, of sound, or of water in fluid motion described there: Whereas those phenomena are due to the composite action or motion of molecules at a more elementary level, light has its own reality at that level. It cannot be understood in terms of an oscillation of some matter that also exists in the dark-no, light is nothing but just that, light. It is an oscillation of an abstract nature, equivalent to a set of numbers that are assigned to each point in space. True, these abstract numbers have implications-most notably, they imply energy. But while a water wave transports energy by the movement of water molecules, the passing of a light wave does not mean that anything material oscillates. The energy of the liquid wave is the energy associated with gravitation and motion of its molecules; the energy of light is energy pure and simple, associated with every illuminated point in space.””

[Henning Genz](https://sms4smile.com/quotes/author/henning-genz/)

## About This Quote

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

Light is an intrinsic oscillation of space itself, not a vibration of matter, carrying energy purely through fields.

**In simple terms:** Light is a wave of space, not of material.
