Quote: "Cosmology is a branch of physics and metaphysics dealing with the nature of the universe."
The study of the origin and evolution of the universe.
Astronomy and astrophysics: These fields study celestial objects, their properties, and behaviors.
Classical mechanics: This branch of physics deals with the motion of objects according to basic laws such as Newton's laws of motion.
General relativity: This theory describes the behavior of objects with strong gravitational fields.
Quantum mechanics: This theory describes the behavior of objects on a very small scale, such as atoms and subatomic particles.
Particle physics: This branch of physics studies the fundamental building blocks of matter and energy, including particles such as quarks and leptons.
Thermodynamics: This branch of physics studies the behavior of systems at the macroscopic level, such as heat and temperature.
Electromagnetism: This branch of physics studies the behavior of electric and magnetic fields.
Cosmological models: These models describe the structure and evolution of the universe as a whole.
Inflationary theory: This theory proposes that the universe underwent a rapid expansion in the first fractions of a second after the Big Bang.
Dark matter and dark energy: These are forms of matter and energy that cannot be observed directly but are thought to be responsible for certain phenomena observed in the universe.
Nuclear physics: This branch of physics studies the behavior and characteristics of atomic nuclei.
Astrophysical observations: Observations of celestial objects are crucial for understanding the universe, and a basic understanding of observational techniques is necessary for studying cosmology.
Mathematical methods: Many of the concepts and theories used in cosmology are complex and require sophisticated mathematical tools for their analysis and understanding.
Data analysis and modeling: The analysis and modeling of observational data is crucial for testing and refining theories of cosmology.
Simulations and computer modeling: Computer simulations are an increasingly important tool in cosmology, allowing researchers to explore the behavior and evolution of the universe under various conditions.
Standard Cosmology: A theoretical model of the universe based on the assumption that the universe is homogeneous and isotropic on a large scale.
Inflationary Cosmology: A model that proposes a brief period of exponential expansion in the early universe to explain why the universe appears to be so homogeneous.
String Cosmology: A theoretical framework in which the universe is described as a system of interacting string-like objects.
Loop Quantum Gravity Cosmology: A model that combines the principles of general relativity and quantum mechanics to describe the universe at its smallest scales.
Brane Cosmology: A theory that proposes our universe is a four-dimensional brane embedded in a higher-dimensional space-time.
Cyclic Cosmology: A model that assumes the universe undergoes a series of infinite cycles of expansion and contraction.
Emergent Cosmology: A model that assumes the universe is a self-organizing system with emergent properties that arise from the interactions among its parts.
Modified Gravity Cosmology: A model that proposes modifications to Einstein's theory of general relativity to explain the observed phenomena in the universe.
Multiverse Cosmology: A framework that proposes the existence of multiple universes, each with its own set of physical laws and parameters.
Quantum Cosmology: A model that applies quantum mechanics to the whole universe to explain the origin and evolution 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."
