1. the branch of astrophysics that studies the origin and evolution and structure of the universe (noun.cognition)
| hypernym | : | astrophysics, |
| definition | : | the branch of astronomy concerned with the physical and chemical properties of celestial bodies (noun.cognition) |
| domain member category | : | big bang theory, big-bang theory, |
| definition | : | (cosmology) the theory that the universe originated sometime between 10 billion and 20 billion years ago from the cataclysmic explosion of a small volume of matter at extremely high density and temperature (noun.cognition) |
| domain member category | : | nebular hypothesis, |
| definition | : | (cosmology) the theory that the solar system evolved from a hot gaseous nebula (noun.cognition) |
| domain member category | : | planetesimal hypothesis, |
| definition | : | (cosmology) the theory that the solar system was formed by the gravitational accumulation of planetesimals (noun.cognition) |
| domain member category | : | continuous creation theory, steady state theory, |
| definition | : | (cosmology) the theory that the universe maintains a constant average density with matter created to fill the void left by galaxies that are receding from each other (noun.cognition) |
| domain member category | : | big bang, |
| definition | : | (cosmology) the cosmic explosion that is hypothesized to have marked the origin of the universe (noun.event) |
| domain member category | : | inflation, |
| definition | : | (cosmology) a brief exponential expansion of the universe (faster than the speed of light) postulated to have occurred shortly after the big bang (noun.event) |
| domain member category | : | closed universe, |
| definition | : | (cosmology) a universe that is spatially closed and in which there is sufficient matter to halt the expansion that began with the big bang; the visible matter is only 10 percent of the matter required for closure but there may be large amounts of dark matter (noun.object) |
| domain member category | : | cosmic string, string, |
| definition | : | (cosmology) a hypothetical one-dimensional subatomic particle having a concentration of energy and the dynamic properties of a flexible loop (noun.object) |
| domain member category | : | hubble constant, hubble parameter, hubble's constant, hubble's parameter, |
| definition | : | (cosmology) the ratio of the speed of recession of a galaxy (due to the expansion of the universe) to its distance from the observer; the Hubble constant is not actually a constant, but is regarded as measuring the expansion rate today (noun.quantity) |
| domain member category | : | ylem, |
| definition | : | (cosmology) the original matter that (according to the big bang theory) existed before the formation of the chemical elements (noun.substance) |
| domain member category | : | dark matter, |
| definition | : | (cosmology) a hypothetical form of matter that is believed to make up 90 percent of the universe; it is invisible (does not absorb or emit light) and does not collide with atomic particles but exerts gravitational force (noun.substance) |
| derivation | : | cosmologist, |
| definition | : | an astronomer who studies the evolution and space-time relations of the universe (noun.person) |
