Cosmology

Home > Physics > Astrophysics > Cosmology

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: "Cosmology is a branch of physics and metaphysics dealing with the nature of the universe."
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."
