Alexander Friedmann, in 1925, was the first to use the equations of general relativity to develop mathematically models of the Universe. He made no effort to say which of these models matched what our Universe actually WAS, or if any observations could resolve this.
Independently of Friedmann's work, Georges LeMaitre did the same in 1927, but said that we live in an expanding universe, and showed that (what later would be called) Hubble Expansion would be seen. LeMaitre's ideas would later be called the Big Bang.
Strangely enough, neither of these works became widely known, so Howard Robertson, as well as Arthur Walker, ALSO -- and all them independently of each other -- later developed these same ideas.
Thus, a Friedmann Universe is connected to Big Bang Cosmology in that one must do the mathematics that Friedmann first did in order to do what LeMaitre later did.
Because all of these men did their work independently, the mathematics is now called the F-L-R-W Metric.
Alexander Friedmann, a Russian mathematician, theorized mathematical models of the universe in 1922, following Einstein's theories. Friedmann's work formed the basis of what we now refer to as the "Big Bang" theory.
It's not - the big bang theory is related to the creation of the Universe, AI is related to human thought.
Jesuit priest Georges LeMaitre first proposed the idea, now known as the Big Bang, as a description of our Universe and as an explanation of observed phenomena. Alexander Friedmann had earlier shown that an expanding universe was a mathematical solution of the equations of general relativity, but did the same with a contracting universe. Friedmann also made no attempt to discern which solution applied to our Univese. Note that LeMaitre and Friedmann did their work independently of each other.
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.
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.
Evidence. See related question.
The Big Bang Theory tells what happen at the begning of the universe. How the Earth comes into the universe
Some questions about the Big Bang theory and its implications for the origin of the universe include: What caused the Big Bang? How did the universe evolve after the Big Bang? What evidence supports the Big Bang theory? What are the implications of the Big Bang for our understanding of the universe's beginning and future?
Perhaps you mean the Friedmann Theory - Alexander Alexandrovich Friedmann is best known for his pioneering theory that the universe was expanding, governed by a set of equations he developed from Albert Einstein's equations of general relativity, showing that the Universe might be expanding in contrast to the static Universe model advocated by Einstein at that time. From these equations he postulated three Friedmann models describing positive, zero and negative curvature respectively. This dynamic cosmological model of general relativity would come to form the standard for both the Big Bang and Steady State theories. However it was Georges Lemaître, a Belgian physicist and Roman Catholic priest, who, in 1927, independently used Friedmann's equations to propose that the inferred recession of the spiral nebulae (per Edwin Hubble's discovery of 1924) was due to the expansion of the Universe. As such, the Jesuit priest Georges LeMaitre was credited with being the first to mathematically detail a cosmological study now known as the Big Bang.
Georges Lemaître, a Belgian physicist and Roman Catholic priest, who, in 1927, independently used Friedmann's equations to propose that the inferred recession of the spiral nebulae (per Edwin Hubble's discovery of 1924) was due to the expansion of the Universe, is called the pioneer or father of the Big Bang Theory. As such, the Jesuit priest Georges LeMaitre was credited with being the first to mathematically detail a cosmological study now known as the Big Bang. However the consensus for modeling cosmology was agreed upon based on the work of four scientists: Alexander Friedmann, Georges Lemaître, Howard Percy Robertson, and Arthur Geoffrey Walker. Occasionally referred to as the FLRW, FRW, FL, or RW (e.g., a complete or partial combination of their last initials) Universe, it presents a metric used to explain Einstein's field equation of general relativity and thus became the foundation for the currently understood version of the standard 'Big Bang Theory'. Note: While the Friedmann Theory preceded the Big Bang Theory, the developed equations were fundamental to establishing a foundation for the Big Bang Theory.

He used the phrase "big bang" in a sarcastic way.
The Nobel Prize has not been awarded specifically for the Big Bang Theory. However, in 1978, the Nobel Prize in Physics was awarded to Arno Penzias and Robert Wilson for their discovery of cosmic microwave background radiation, which provided strong evidence for the Big Bang Theory.
