A model describing the Universe as static and not changing. According to this model the Universe always existed and always will, and it was in the past the same way we see it today.
The steady-state theory is obsolete - it is now known that the Universe does change over time (the Steady-State Theory states that it doesn't). According to the Steady-State Theory, the Universe has no beginning and no end.
The steady-state universe theory
The steady state model assumes that new matter is created at the universe expands, the big bang theory states that no new matter is ever created, but only changes form.
Red shift supports the steady state theory in that the red shift indicates the Continuity Condition. Steady State means Conservation of Energy and does not require an expanding universe. It is the misunderstanding of red shift that adds the requirement of an expanding universe and the need for continuous creation.Hubble saw red shift as a "hitherto unrecognized principle of nature", not an expansion of the universe. less prudent physicists have misunderstood red shift. Red shift is an indicator of "continuity condition" and the result of centrifugal force balancing gravitational centripetal force.Steady State is the proper term for Conservation of Energy or Homeostasis, which seems to characterize the universe. "Steady State Theory" without expansion is well supported by red shift.The proper Theory of Gravity, E = -mu/r + mcV, accounts for 'dark Energy and red shift" and a finite universe.

The steady-state universe theory
The steady state model assumes that new matter is created at the universe expands, the big bang theory states that no new matter is ever created, but only changes form.
The Steady State Universe was an enhancement of upon Albert Einstein's Static Universe and was proposed in 1948 by Hermann Bondi, Thomas Gold, and Fred Hoyle. The revised Steady State Theory was based on an extension of something called the Perfect Cosmological Principle, which holds that the universe looks essentially the same from every spot in it and at every time. Or more simply stated, the revised Steady State Theory promotes that new matter and energy are continuously created as the universe expands and the rationalization for an ageless universe.
steady state theory
Observational data does not support the Steady State Theory. The central idea of the Steady State Theory is that the aspect of the Universe (the way it looks) won't change over time; it is quite clear, from observations, that in the remote past, the Universe looked quite different from what it looks now.
The Steady State theory states that matter is produced in the universe at a continuous rate, so that the universe stays constant throughout space and time. It is no longer an accepted theory in much of the scientific community.
Steady State is not a "discovery", it's a hypothesis that has been disproved. According to Steady State, the Universe in the past should look the same as it does now. Observations of far-away galaxies show that this is not the case.
The steady state theory was disproved by observations in the sense that at larger distances, the Universe doesn't look the same as nearby. This means the Universe has changed over time, directly contradicting the main assumption of the steady state theory. - I am not sure to what extent quasars were involved, but quasars do tend to show up more frequently at greater distances, i.e., in the early Universe.
proposes that the universe looks the same on large scales to observers.
