"Dynamically stable, non-expanding or non-stretching Universe models; space does not 'expand' with these models."
"Do not confuse with Steady-state models which employ space expansion."

The Big Bang is the theory that was developed to describe the origins of the universe.
It is similar to the Big Bang theory. The ekpyrotic theory is, a theory that their is a parallel universe (More than one) In our universe.
Ptolemy created the geocentric theory of the universe and Nicolous Copernicus created the heliocentric theory of the universe.
The Big Bang theory
A "no boundary" universe is a universe where the change in energy is positive or negative everywhere in the universe. Such a universe theory calls for everywhere expansion or everywhere contraction. The current central dogma in Astronomy is for such an expanding universe. The corrected Law of Gravity indicates that the universe is bounded and not expanding.
Before the Big Bang theory, many scientists believed that the universe was static, or infinitely unchanging.
The Theory of Relativity was created by Einstein, not by Eisenstein. Comment: The most obvious thing is that Einstein's equations predicted that the Universe was not "static". So a "Big Bang", expanding Universe fits the theory.
Mainly, the redshift of distant galaxies, which indicates that they are moving away from us. Also:* Calculations, to the effect that the Universe can't be static. * The microwave background radiation, which agrees closely with the theory. * The percentage of elements (and isotopes) in the Universe, which also closely agrees with the theory.
According to Kepler's Universe theory, the universe was born in 4977 BC.
The no boundary universe theory was formulated in 1983.
The steady-state universe theory
Friedmann Universe Theory was created in 1922.
The Big Bang is the theory that was developed to describe the origins of the universe.
"I believe in the oscillating universe theory."
It is similar to the Big Bang theory. The ekpyrotic theory is, a theory that their is a parallel universe (More than one) In our universe.
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.
Well I do now one theory about the universe. It's the big bang theory. The big bang theory is a theory about how the universe was created.Scientist think that a big explosion created the universe.Scientist found lots of evidence that the big bang theory was true.
