Quote: "Cosmology is a branch of physics and metaphysics dealing with the nature of the universe."
The study of the universe, its origin, evolution, and eventual fate. Includes topics such as the Big Bang theory, dark matter, and dark energy.
Big Bang Theory: The scientific explanation for the origin of the universe.
Hubble's Law: The relationship between the distance of galaxies and their redshifts, used to determine the rate of cosmic expansion.
Cosmic microwave background radiation: The residual radiation of the Big Bang that fills the observable universe.
Dark matter: The invisible matter that cannot be detected through conventional observational methods, but interacts with gravity.
Dark energy: The mysterious energy pushing the universe to accelerate its expansion.
Inflationary theory: The theory that the universe underwent a rapid period of expansion in its early stages.
Black holes: Extremely dense regions of space where gravity is so strong that nothing, not even light, can escape.
Neutron stars: Extremely dense stars composed almost entirely of neutrons.
Supernovae: The explosive deaths of massive stars, leading to the formation of black holes or neutron stars.
Solar system formation: The process by which planets, asteroids, comets, and other bodies were formed from a protoplanetary disk around the early Sun.
Red giants: Large, aging stars that have exhausted their hydrogen fuel and are fusing heavier elements.
White dwarfs: The remnants of stars less than 8 times the mass of the Sun, composed of electron-degenerate matter.
Gravitational waves: Ripples in the fabric of space-time caused by violent cosmic events like black hole mergers.
Nucleosynthesis: The process by which simple atomic nuclei fuse together to form heavier elements.
Exoplanets: Planets outside of our Solar System.
Galactic evolution: The formation and evolution of galaxies over time.
Cosmic ray physics: The study of extremely high-energy particles that originate outside of the Solar System.
High energy astrophysics: The study of astronomical objects and phenomena that involve high energies, such as gamma-ray bursts, active galactic nuclei, and pulsars.
Stellar astrophysics: The study of stars, their formation, evolution, and eventual fates.
Black hole thermodynamics: The study of the relationship between black holes and thermodynamics, including the concept of black hole entropy.
Physical Cosmology: It deals with the study of the origin and evolution of the universe, structure formation, and the large-scale properties of the cosmos, using the principles and techniques of physics.
Mathematical Cosmology: It is a branch of cosmology that deals with the mathematical modeling of the universe using analytical and numerical techniques.
Observational Cosmology: It is a branch of cosmology that deals with the observation and measurement of celestial objects and phenomena in the universe using various telescopes and instruments.
Particle Cosmology: It is a subfield of cosmology that deals with the study of the behavior of elementary particles in the early universe and their interaction with the cosmic microwave background radiation.
Inflationary Cosmology: It is a theory that explains the rapid expansion of the universe in its first moments after the Big Bang and its subsequent evolution.
String Cosmology: It is a theoretical framework that incorporates the principles of string theory in the study of the early universe and its evolution.
Loop Quantum Cosmology: It is a theory that incorporates the principles of loop quantum gravity in the study of the early universe and its evolution.
Brane Cosmology: It is a theory that incorporates the principles of M-theory in the study of the early universe and its evolution.
Modified Gravity Cosmology: It is a theory that explains the observed properties of the universe by modifying the laws of gravity at very large scales.
Dark Energy Cosmology: It is a theory that explains the observed acceleration of the expansion of the universe by introducing a new form of energy called dark energy.
Multiverse Cosmology: It is a theoretical framework that incorporates the possibility of the existence of multiple universes and explores their properties.
Topological Cosmology: It is a theory that investigates the topology of the universe and its implications for its evolution and structure.
Cosmoarcheology: It is a subfield of cosmology that deals with the search for evidence of advanced civilizations in the universe.
Cosmoclimatology: It is a subfield of cosmology that investigates the role of cosmic factors in climate change on Earth.
Planck Cosmology: It is a branch of cosmology that deals with the analysis of data from the Planck spacecraft, which mapped the cosmic microwave background radiation in detail.
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: "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."
