Quote: "Cosmology is a branch of physics and metaphysics dealing with the nature of the universe."
A subfield that studies the origins, structure, and evolution of the universe on a large scale.
Theories of the Universe: Different models and theories about the origin, evolution, and structure of the Universe.
Big Bang Theory: A scientific theory that explains the early development of the Universe, starting from a hot, dense, and infinitely small point.
Cosmic Inflation: A period of exponential expansion of the Universe that occurred immediately after the Big Bang, which explains its large-scale structure and homogeneity.
Dark Matter: Unidentified matter that constitutes around 27% of the mass-energy of the Universe and is responsible for the observed gravitational lensing and structure formation.
Dark Energy: A hypothetical form of energy that permeates all space and is responsible for the observed accelerated expansion of the Universe.
Cosmic Microwave Background Radiation: The afterglow of the Big Bang, which is the most direct evidence for its occurrence and provides insight into the early conditions of the Universe.
Large-Scale Structure of the Universe: The observed distribution of galaxies and galaxy clusters on very large scales, which can be used to infer the origin and evolution of the Universe.
Formation and Evolution of Galaxies: The processes of star formation, feedback, mergers, and interactions that shape the morphology and properties of galaxies.
High-Energy Astrophysics: The study of cosmic sources of high-energy radiation, such as black holes, neutron stars, and quasars, which can reveal the most extreme physical processes in the Universe.
Gravitational Waves: Ripples in the fabric of spacetime caused by massive objects moving or colliding, which provide a new way to observe the Universe and test general relativity.
Physical Cosmology: This is a broad field concerned with the study of the universe's origin, evolution, and eventual fate using physical laws and principles.
Cosmogony: This is a subfield of physical cosmology that focuses specifically on the study of the universe's origin and early evolution.
Mathematical Cosmology: This is a subfield that uses advanced mathematical methods to analyze and model the structure and evolution of the universe.
Observational Cosmology: This is a subfield that focuses on the collection and interpretation of observational data about the universe to test and refine cosmological models and theories.
Theoretical Cosmology: This is a subfield that uses mathematical modeling and analysis to develop and test new theoretical models and hypotheses about the universe.
Particle Cosmology: This is a subfield that studies the role of subatomic particles in the structure and evolution of the universe.
Inflationary Cosmology: This is a subfield that explores the impact of cosmic inflation on the structure and content of the universe.
Dark Matter Cosmology: This is a subfield that studies the role of dark matter in the structure and evolution of the universe.
Dark Energy Cosmology: This is a subfield that studies the role of dark energy in the expansion and acceleration of the universe.
Quantum Cosmology: This is a subfield that seeks to formulate a quantum theory of cosmology that could explain the origin and evolution of the universe at the smallest scales of space and time.
Quote: "The term cosmology was first used in English in 1656 in Thomas Blount's Glossographia."
Quote: "In 1731 taken up in Latin by German philosopher Christian Wolff, in Cosmologia Generalis."
Quote: "Religious or mythological cosmology is a body of beliefs based on mythological, religious, and esoteric literature and traditions of creation myths and eschatology."
Quote: "In the science of astronomy, cosmology is concerned with the study of the chronology of the universe."
Quote: "It is investigated by scientists, including astronomers and physicists, as well as philosophers, such as metaphysicians, philosophers of physics, and philosophers of space and time."
Quote: "Theories in physical cosmology may include both scientific and non-scientific propositions and may depend upon assumptions that cannot be tested."
Quote: "Physical cosmology is a sub-branch of astronomy that is concerned with the universe as a whole."
Quote: "Modern physical cosmology is dominated by the Big Bang Theory."
Quote: "The Big Bang Theory attempts to bring together observational astronomy and particle physics."
Quote: "A standard parameterization of the Big Bang with dark matter and dark energy, known as the Lambda-CDM model."
Quote: "Cosmology is a 'historical science' because 'when we look out in space, we look back in time' due to the finite nature of the speed of light."
Quote: "Physical cosmology is the study of the observable universe's origin, its large-scale structures, and dynamics, and the ultimate fate of the universe."
Quote: "Scientists, including astronomers and physicists, as well as philosophers, such as metaphysicians, philosophers of physics, and philosophers of space and time."
Quote: "Physical cosmology relies on scientific observations and theories, while religious or mythological cosmology is based on beliefs from various literary and cultural traditions."
Quote: "Physical cosmology is concerned with the study of the observable universe's origin, its large-scale structures, and dynamics."
Quote: "Theories in physical cosmology may depend upon assumptions that cannot be tested."
Quote: "To understand the nature and history of the universe and its ultimate fate."
Quote: "Cosmologists, including philosophers of space and time, investigate the fundamental aspects of space, time, and their relationship in the context of the universe."
Quote: "Cosmology is considered a 'historical science' because 'when we look out in space, we look back in time' due to the finite nature of the speed of light."
