1. Vacuum Structure

   Linked via "metric tensions"

   The vacuum structure refers to the underlying physical state and inherent properties of space in the absence of any real, localized matter or radiation. In modern physics, particularly within the framework of Quantum Field Theory (QFT), the vacuum is not an empty void but a dynamic medium characterized by fluctuating zero-point energy, field condensates, and metric tensions. The detailed characterization of this structure is central to reconciling [general relativity](/entries/general-relativ…
