Quote: "Cosmology is a branch of physics and metaphysics dealing with the nature of the universe."
The study of the origin, evolution, and structure of the universe.
General Relativity: This is a fundamental theory of gravity that describes the curvature of spacetime, a concept that is central to understanding cosmology.
Special Relativity: This theory explains the behavior of space and time in the absence of gravity and is essential to understanding the relationship between energy and mass.
Dark matter: This is a hypothetical type of matter that does not interact with light, but has a significant gravitational effect on the observable universe.
Dark energy: This is a mysterious form of energy that is thought to be responsible for the accelerating expansion of the universe.
Big Bang theory: This is the prevailing cosmological model that describes the origin and evolution of the universe.
Inflation theory: This is a theory that proposes that the universe underwent a period of exponential expansion shortly after the Big Bang.
Cosmic microwave background radiation: This is the radiation that is leftover from the Big Bang and provides evidence for the early evolution of the universe.
Black holes: These are regions of space where gravity is so strong that nothing, not even light, can escape.
Neutron stars: These are extremely dense, compact stars formed from the remains of supernovae.
Gravitational waves: These are ripples in spacetime that are predicted by general relativity and were recently detected for the first time.
Quantum mechanics: This is a fundamental theory that describes the behavior of matter and energy at the smallest scales.
String theory: This is a theoretical framework that attempts to reconcile general relativity and quantum mechanics by postulating the existence of extra dimensions.
Theoretical cosmology: This is the study of the universe as a whole, using mathematical models and theoretical frameworks.
Observational cosmology: This is the study of the universe through observations and experiments, including the use of telescopes and other instruments.
Cosmological simulations: These are computer models that simulate the evolution of the universe, providing insights into its structure and behavior.
Classical Cosmology: It is a branch of cosmology that deals with the study of the universe's structure, size, origin, and evolution using the laws of classical physics.
Quantum Cosmology: It is a branch of cosmology that aims to apply the principles of quantum mechanics to model the evolution of the universe.
Inflationary Cosmology: It is a theory proposing that the universe underwent a period of exponential expansion right after the Big Bang, which is thought to explain the uniformity of the cosmic microwave background radiation.
String Cosmology: It applies the principles of string theory to cosmology, aiming to explain the universe's structure and evolution at the most fundamental level.
Loop Quantum Cosmology: It is a branch of quantum cosmology that deals with the study of the universe's structure and evolution using the principles of loop quantum gravity.
Brane Cosmology: It posits the existence of a higher-dimensional space that contains our universe, leading to a different understanding of the universe's origin and expansion.
Fractal Cosmology: It looks at the universe as a fractal object, meaning that its structure repeats at different scales.
Emergent Cosmology: It is a theory that proposes the universe's structure and evolution can be explained by emergent laws that arise from the interactions of its constituent parts.
Modified Gravity Cosmology: It is a theory of cosmology that proposes alternative explanations for the universe's structure and evolution by modifying the laws of gravity.
Cosmological Inference: It involves the use of statistical techniques to extract information about the universe's properties from observational data.
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."
