Steady State Theory
ConceptAbout
The Steady State Theory is a cosmological model proposing that the universe is constantly expanding while maintaining a constant average density. This is achieved through the continuous creation of matter, balancing the expansion of space. Developed by Fred Hoyle, Thomas Gold, and Hermann Bondi in 1948, it served as an alternative to the Big Bang theory. The theory suggests that the universe has no beginning or end, existing infinitely in both time and space. Key features include the perfect cosmological principle, which states that the universe appears the same at all times and places. The theory acknowledges local changes, such as star life cycles, but asserts that on a grand scale, the universe remains unchanged. However, the discovery of cosmic microwave background radiation in the 1960s significantly diminished its support, favoring the Big Bang model instead. Despite this, the Steady State Theory remains an interesting historical concept in cosmology.
