Steady State Theory was a theory proposed in twentieth-century cosmology to explain evidence that the universe was expanding, but still retain the core idea that the universe always looks the same, and is therefore unchanging in practice (and has no beginning and no end). This idea has largely been discredited due to astronomical evidence that suggests the universe is, in fact, changing over time. STEADY STATE THEORY BACKGROUND AND DEVELOPMENT When Einstein created his theory of general relativity, early analysis showed that it created a universe that was unstable — expanding or contracting — rather than the static universe that had always been assumed. Einstein also held this assumption about a static universe, so he introduced a term into his general relativity field equations called the cosmological constant, which served the purpose of holding the universe in a static state. However, when Edwin Hubble discovered evidence that distant galaxies were, in fact, expanding away from the Earth in all directions, scientists (including Einstein) realized that the universe didn’t seem to be static and the term …
