Bianchi type cosmologies

Target entity: Bianchi type cosmologies
Context triple: [Gödel metric, relatedTo, Bianchi type cosmologies]

• A. FLRW cosmological models
  FLRW cosmological models are a family of solutions to Einstein’s field equations that describe a homogeneous and isotropic expanding or contracting universe, forming the standard framework for modern cosmology.
• B. American school of relativistic cosmology
  The American school of relativistic cosmology was a mid-20th-century research tradition in the United States that advanced the mathematical and physical foundations of general relativity and modern cosmology through the work of theorists such as Howard P. Robertson.
• C. An Essay in Cosmology
  An Essay in Cosmology is the subtitle of Alfred North Whitehead’s major philosophical work *Process and Reality*, which presents his influential process philosophy and metaphysical system.
• D. Lemaître–Tolman metric
  The Lemaître–Tolman metric is an exact spherically symmetric, inhomogeneous solution of Einstein’s field equations used in cosmology to model non-uniform distributions of matter without assuming spatial homogeneity.
• E. Essai de cosmologie
  Essai de cosmologie is an 18th-century philosophical and scientific treatise by Pierre-Louis Moreau de Maupertuis that explores the structure and origins of the universe within the framework of early Enlightenment cosmology.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
