Study Notes
Cosmological Theories
- The Big Bang Theory proposes that the universe started as a singularity, an area predicted to be in the core of a black hole with very high temperature and density.
Cosmological Models
- The Bread-Raisin Model represents the expanding universe, where the bread represents space and the raisins represent galaxies.
Steady-State Theory
- According to the steady-state theory, the average density of the universe remains constant despite the continuous expansion.
Universe Core Formation
- Homogeneous accretion explains the idea that the universe's core formed through the gradual accumulation of matter.
Cyclic Model
- The oscillating universe theory proposes that the universe is expanding and will eventually collapse and begin another cycle of expansion.
