Multiverse ideas gained scientific weight in the 1980s with the invention of inflation, a period when the early universe suddenly expanded.Inflation explains why the cosmos is so flat and smooth

https://en.wikipedia.org/wiki/Inflation_(cosmology)
In physical cosmology, cosmic inflation, cosmological inflation, or just inflation, is a theory of exponential expansion of space in the early universe.The inflationary epoch is believed to have lasted from 10 −36 seconds to between 10 −33 and 10 −32 seconds after the Big Bang.Following the inflationary period, the universe continued to expand, but at a slower rate.

The Inflation Theory proposes a period of extremely rapid (exponential) expansion of the universe during its first few moments. It was developed around 1980 to explain several puzzles with the standard Big Bang theory, in which the universe expands relatively gradually throughout its history. Limitations of the Big Bang Theory.

Physicist Alan Guth, the father of cosmic inflation theory, describes emerging ideas about where our universe comes from, what else is out there, and what caused it to exist in the first place.

https://cmb.sites.stanford.edu/research/cosmology/cosmic-inflation
Cosmic inflation is the theory that the universe underwent a brief period of exponential expansion a small fraction of a second after the Big Bang singularity. This idea was initially introduced in the 1980s as the most natural solution to several problems with the standard Big Bang model, including the Flatness Problem, the Horizon Problem

https://cfa.harvard.edu/news/can-cosmic-inflation-be-ruled-out
Cambridge, MA - A team of astrophysicists say that cosmic inflation — a point in the universe's infancy when space-time expanded exponentially, and what physicists really refer to when they talk about the 'Big Bang' — can in principle be ruled out in an assumption-free way.. The astrophysicists, from the University of Cambridge, the University of Trento, and Harvard University, say that

In the standard big bang cosmology (without inflation), Ω = 1 is an unstable solution: If Ω were ever-soslightly less than 1 at an early time, then it would rapidly slide toward 0. For example, if Ω were 0.9 at 1 s after the big bang, it would be only 10 -14 today.

The Big Bang was a tremendous theory, but it had a few problems. In 1980 Alan Guth developed the revolutionary theory of cosmic inflation, and astronomers have been looking for evidence to this day.

https://www.physicsoftheuniverse.com/topics_bigbang_inflation.html
Cosmic inflation is the idea that the very early universe went through a period of accelerated, exponential expansion during the first 10 -35 of a second before settling down to the more sedate rate of expansion we are still experiencing, so that all of the observable universe originated in a small (indeed, microscopic) causally-connected region.

In the 1980s, cosmologists began developing a theory called cosmic inflation that hypothesized that immediately after the Big Bang the universe expanded with unexpected rapidity, an idea thought to be necessary for the development of the large-scale structures such as stars and galaxies that are important features of the universe we inhabit

Hoping to build on the Big Bang, American physicist Alan Guth proposed the theory of cosmic inflation in 1981. Since then, c osmic inflation has become an important concept in the study of the

Cosmic inflation arises from types of matter and interactions that we now know to exist — hurray, Higgs boson! — and it addresses several long-standing cosmic puzzles. Inflation makes several specific predictions for what the universe should look like today. Simple models fit the latest observations to astonishing accuracy.

Nature reporter Ron Cowen explores Professor Alan Guth's theory of cosmic inflation, which scientists may have confirmed by searching for gravitational waves from the seconds after the Universe's formation. "Guth's idea was that the cosmos expanded at an exponential rate for a few tens of trillionths of trillionths of trillionths of seconds after the Big Bang, ballooning from subatomic

As the Big Bang theory goes, somewhere around 13.8 billion years ago the universe exploded into being, as an infinitely small, compact fireball of matter that cooled as it expanded, triggering reactions that cooked up the first stars and galaxies, and all the forms of matter that we see (and are) today.

We think the Big Bang was the beginning of time and space itself. But there are problems with this story. T he energy of empty space - known as the cosmological constant - poses one major problem.
