There are a number of problems with the steady-state theory, but at the time the theory was proposed, there were also points in its favor.
The steady-state theory rests on the foundation of the perfect cosmological principle. Hence, any evidence that the universe evolves is evidence against the steady-state theory. The existence of quasars and the change in the expansion rate of the universe a few billion years in the past, discussed earlier, are evidence against the steady-state. This evidence for the evolution of the universe did not exist in 1948, when the steady-state theory originated. It became part of the cumulative weight of evidence that had built up against the steady-state theory by the mid 1960s. In gallant attempts to save the steady-state theory, its proponents, chiefly Hoyle and Jayant Narlikar, have argued that the universe can change over time periods of a few billion years without violating the perfect cosmological principle. We must look at even longer time spans to see that these changes with time average out.
The cosmic background radiation is widely considered the final blow to the steady-state theory. Again, proponents of the steady-state theory have made gallant efforts to save their theory in the face of what most astronomers consider overwhelming evidence. They argue that the background radiation could be the cumulative radiation of a large number of radio sources that are too faint to detect individually. This scheme requires the existence of roughly 100 trillion (about 10,000 times the number of observable galaxies) such sources that about are one millionth as bright as the radio sources we do detect. Few astronomers are willing to go to such great lengths to rescue the steady-state theory.
Another objection raised against the steady-state theory is that it violates one of the fundamental laws of physics as that law is currently understood. The law of conservation of matter and energy states that matter and energy...
