1. Steady State Theory; Bondi, Gold, & Hoyle Theoretical Model New matter is continuously created to keep the amount of material in density of the universe the same. It is a finite universe with a repeating pattern. Material is created, expands, and new material is created.

2. New material is created in this model to keep the density of the universe the same.

3. Pros and Cons Support This theory was theoretical and based on primitive observations of our universe. Scientists used mathematical calculations to support Problems The model was disproven with CMBR. CMBR showed that there was initially one point of expansion not many.
