A '''field''' is a physical quantity that has a value at every point in space and time. In modern physics, fields provide the fundamental description of nature, underlying both particles and interactions.

== Description ==
Fields describe how physical quantities vary across space and time. Classical examples include electric and gravitational fields, while in quantum theory fields are the basis for describing particles.

== Properties ==

* defined at every point in space and time
* can carry energy and momentum
* underlying description of physical systems
