There are a few different theories about the origin of the universe. One of them is the Steady State theory put forward originally by Sir James Jeans around 1920 then adapted by Hermann Bondi, Thomas Gold and Sir Fred Hoyle in the late 1940's.
The Steady State theory offered a simple solution to the way the universe was made, but as we look further back into the earlier stages of the developing universe involving temperatures , astronomers started to see contradictions to the theory. Interestingly, the theory known as Big Bang initially based on the work of Father Lemaitre in 1927,was so named by Sir Fred Hoyle in 1950 over a radio interview and then gained in popularity. Fred's own Steady State theory was based on the idea that the temperature of the universe did not change as space expands, however in 1964 Hoyle's theory lacked support with better instruments able to detect cosmic background radiation which showed cooling temperatures of the universe expanding.
 | The term 'Steady State' means hasn't changed, it has remained in the same state. The proposed Steady State theory meant that the universe was always there though ever expanding with matter being continuously created to form new stars at the same rate that old ones become difficult to observe. The universe will never move nor age and as a star dies, another will form in its place. However, there is not a great deal of evidence to support this theory yet there is considerable evidence to contradict it.
Many scientists don't believe in this theory because the theory states, "That the universe has been here forever and was never actually started," a universe that has no beginning or end in time. More importantly to note is that Scientists contradict this Steady State theory because of the idea that from any point within the universe the view of the average density and arrangement of galaxies is the same! Telescopic observations since the 1950's have produced contradictory evidence to the 'Steady State' theory and is more supportive of the 'big bang model. At present, the universe is emitting mircowaves of light. This is known as 'cosmic background radiation.' These waves can be measured on a scale to show whether the waves are coming towards us or moving away. These waves that are being measured are moving away and this is known as redshift. The redshift is what astronomer Hubble used to show that every distant galaxy appeared to be moving away from each other at a linear rate.In physics red shift happens when light seen coming from an object that is moving away is increased in wavelength , or shifted to the 'red' end of the spectrum. |
