Glossary
- Big Bang Theory: A theoretical model of the universe that begins with the explosion and rapid expansion of a single point with infinite density
- Ultimate Fate of the Universe: Cosmological concept that theorizes how the universe will end
- Big Crunch: Theoretical end of the universe where the gravity in the universe draws all matter into a massive black hole
- Big Freeze: Alternative theoretical end of the universe scenario where expansion has continued to the point of maximum entropy and there is not enough thermodynamic energy for any processes to take place
- Multiverse: Theorizes that since reality is made up of an infinite number of universes, it is feasible that some will come to an end while others will not
Types of Cosmology
- Physical (study of the largest-scale structures in astronomy without any kind of religious assumptions).
- Metaphysical (concerned with explaining the fundamental nature of being and the world).
- Religious (explains the history and structure of the universe based on religious values).
- Esoteric (a subset of metaphysical cosmology concerned with explaining universal phenomena based on philosophical beliefs).
