After confirmation of the hubble's law by observation, the two most popular cosmological theories became the steady state theory of hoyle, gold and bondi, and the big bang theory of ralph alpher, george gamow, and robert dicke with a small number of supporters of a smattering of alternatives. The big bang and the steady state model it is always a mystery about how the universe began, whether if and when it will end astronomers construct hypotheses called cosmological models that try to find the answer there are two types of models: big bang and steady state however, through many observational evidences, the big bang theory can best.
When the steady – state model was first suggested, the best estimate of the age of the universe in the context of the big bang model was about two billion years however, the earth and solar system are about five billion years old. At the time the steady state model was proposed, the big bang model was in trouble because the value of the hubble constant was clearly bigger than the inverse of the age of the universe maran describes the birth and death of the steady state theory without reference to the microwave background there is a difference in χ 2 of 5163.

There was a competing theory called the steady state theory for teachers as per the big bang in the mid 1960s, two scientists working for bell telephone laboratories were concentrating on. The big bang theory and the steady state theory are two theories trying to explain the beginning and the evolution of the universe this article will try to compare the two theories and discuss the differences between them. In cosmology, the steady state model is an alternative to the big bang theory of the evolution of our universe in the steady state model, the density of matter in the expanding universe remains unchanged due to a continuous creation of matter, thus adhering to the perfect cosmological principle , a principle that asserts that the observable universe is basically the same at any time as well as at any place.
Steady state universe - this non-standard cosmology (ie opposed to the standard big bang model) has occurred in various versions since the big bang theory was generally adopted by the scientific community. Big-bang model, widely held theory of the evolution of the universe its essential feature is the emergence of the universe from a state of extremely high temperature and density —the so-called big bang that occurred 138 billion years ago.
The theory was one alternative to the big bang which, like the big bang, agreed with key observations of the day, namely hubble's red shift observations, and hoyle was a strong critic of the big bang.
