First proposed by Sir James Jeans around 1920(known as continuous creation), and then reintroduced by Sir Hermann Bondi and Thomas Gold in 1948, with revisons by Sir Fred Hoyle, the Steady State theory of the origin of the universe states simply that while the universe is indeed always expanding, the density always remains the same due to the continued creation of new matter to form stars and galaxies to replace the older ones that are no longer observable due to their increasing velocity of recession and distance from us. The theory also states that the universe had no beginning and thus will have no end and that the density of matter within the universe is on average the same everywhere. Although, this theory seems a bit outdated now, (observations over the last 40 years tending to support the Big Bang model), there was a time when this theory was considered to be the prime candidate for describing the origin and evolution of the universe. |
