What is the Steady State Theory?

Answer 1

The Steady State Theory is an alternative cosmological model that suggests that the universe is eternal, unchanging, and has always existed in an essentially steady state. According to this theory, matter is continuously created to maintain a constant average density as the universe expands. This concept opposes the Big Bang Theory, which states that the universe originated from a singular event known as the Big Bang around 13.8 billion years ago. The Steady State Theory was popular in the mid-20th century but was largely abandoned in favor of the overwhelming evidence supporting the Big Bang Theory.
