Suddenly, the singularity began expanding, and the universe as we know it began while this is not the only modern theory of how the universe came into being – for example, there is the steady state theory or the oscillating universe theory – it is the most widely accepted and popular not only does the. The universe is observed to be expanding, so if the density remains the same, matter must be continuously created this radical assumption is not the reason that the steady state model is now rejected like any good scientific model, the steady state made many quantitative testable predictions, and these. Steady state theory propones the idea that the universe looks the same no matter the viewpoint and that the universe has always looked like this essentially, the the theory states that the universe is uniform throughout both time and space the advantage of steady state theory over some other theories is its simple and. The big bang model can explain the existence of the cmb while the steady-state model cannot when we look carefully at the beginning assumptions ( presuppositions) of those who believe in the big bang and those who believe that god created the universe, we see that it all comes down to where you. But the theory of an initial cosmic explosion was soon challenged by a new hypothesis—that the universe might be in a steady state after all in 1946 the bondi and gold insisted that the universe is not only homogenous in space but also in time—it looks the same at any place and at any time they grandly called this the.
With the announcement earlier in the week of what appears to be direct evidence for cosmic inflation, i ended up getting involved in a discussion on one of john gribbin's facebook posts with a gentleman who said the big bang theory will be discredited in the next few years (or words to that effect), and. The doppler effect: draw in a series of diagrams in the 4 boxes which show how light can appear to be blue shifted and red shifted you can use a extension ideas: learners could debate evidence for and against the big bang theory, after researching some of the alternative theories, such as the steady state theory. Almost two decades later, a similar “steady state” universe would be proposed by fred hoyle, hermann bondi, and tommy gold, in papers published in 1949 but these models of the universe are not supported by modern theories in fact, a tenet of modern cosmology is that as the universe will expand a.
In the 1950s and earlier 1960s, there was quite wide support for the hoyle/gold/ bondi “steady state” cosmology as a rival to what we now think of as a big bang model the basic idea is that the universe, on the big scale, “looks the same” at every time, as well as in every direction and this temporal isotropy. Using hubble's data and the big bang theory, it seemed like the sun was older than the universe and the original big bang paper was conceptually brilliant but technically flawed in this environment, other theories seemed equally plausible perhaps the universe was in a “steady state”, where new matter. Looking back in time the main alternative to the big bang theory of the universe is called the steady state theory in this theory, the universe does not change very much with time remember that because light takes a long time to travel across the universe, when we look at very distant galaxies, we are also looking back in. This figure is an illustration of the steady state theory notice that the contents of the universe look the same even as it expands it is like baking a cake the cake is just the dough heated up to a point of expansion the baked cake and the dough are the same material, except the cake is the expanded.
The steady state theory was proposed in 1948 by hermann bondi, thomas gold, and fred hoyle it was derived from the perfect cosmological principle, which states that the universe looks essentially the same from every location within it at all times (in a macroscopic sense) this was philosophically. 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. Therefore, the universe is expanding, and the big bang model seems more reasonable than the steady state model the second observational evidence is the radiation produced by caes, charles j cosmology: the search for the order of the universe usa: tab books inc, 1986 p 72 7 gribbin, john in search of.
The basic tenet of the steady-state theory is that the universe on a large scale does not change with time (evolve) it has always existed and will always continue to exist looking much as it does now the universe is, however, known to be expanding to allow for this expansion in an unchanging universe, the authors of the. Steady-state theory, in cosmology, a view that the universe is always expanding but maintaining a constant average density, with matter being continuously created to form new stars and galaxies at the same rate that old ones become unobservable as a consequence of their increasing distance and velocity of recession. The answer is that not only is the big bang the best theory to explain the start and evolution of the universe, it's the only one that doesn't make incorrect predictions let's see this in action well, if we look at the universe when it was early enough, it would also be denser and hotter in fact, we can go back.

Far from it: while a strong contender for the title, it had some powerful rivals, especially the steady state theory see, edwin hubble had correctly pointed out two fantastic facts about our universe: it's very, very, very large, and it seems to be getting bigger or at least, it looks like every galaxy is getting farther.
Fred hoyle and others developed the steady state theory to challenge the big bang theory fred hoyle discusses his ideas in video clips from the bbc archive. The theory has been largely abandoned in favor of the big bang theory, largely due to the discovery of quasars and other entities that appear only at very great distances, suggesting an absolute relationship between the age of objects and their distance steady state theory was also discredited by the discovery of cosmic. The key importance of the steady-state model is that as a competitor to the big bang, it was an impetus in generating some of the most important research in the steady state theory asserts that although the universe is expanding, it nevertheless does not change its look over time (the perfect cosmological.
