Wow! This breakthrough idea later became known as the Big Bang! The Big Bang was the moment 13.8 billion years ago when the universe began as a tiny, dense, fireball that exploded. Most astronomers use the Big Bang theory to explain how the universe began.
According to the standard Big Bang model, the universe was born during a period of inflation that began about 13.8 billion years ago. Like a rapidly expanding balloon, it swelled from a size smaller than an electron to nearly its current size within a tiny fraction of a second. Initially, the universe was permeated only by energy.
The earliest stages of the universe’s existence are estimated as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level. Diagram of evolution of the (observable part) of the universe from the Big Bang (left), the CMB -reference afterglow, to the present.
The chronology of the universe describes the history and future of the universe according to Big Bang cosmology. The earliest stages of the universe’s existence are estimated as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level.

Who created the universe in?
Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.
How did universe get started?
Our universe began with an explosion of space itself – the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.

The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.
What began the Big Bang?
The universe began, scientists believe, with every speck of its energy jammed into a very tiny point. This extremely dense point exploded with unimaginable force, creating matter and propelling it outward to make the billions of galaxies of our vast universe. Astrophysicists dubbed this titanic explosion the Big Bang.
Was the Big Bang 13.8 billion years ago?
Detailed measurements of the expansion rate of the universe place the Big Bang singularity at around 13.8 billion years ago, which is thus considered the age of the universe.
How did Big Bang happen from nothing?
Instead of extrapolating “hot and dense” back to an infinitely hot, infinitely dense singularity, inflation basically says, “perhaps the hot Big Bang was preceded by a period where an extremely large energy density was present in the fabric of space itself, causing the Universe to expand at a relentless (inflationary) …
Did time not exist before Big Bang?
Mind-Bending Study Suggests Time Did Actually Exist Before The Big Bang. According to a straightforward interpretation of general relativity, the Big Bang wasn’t the start of ’everything’.

Wait, start at the beginning. Of everything.

The universe started very, very small and quickly expanded to the size of a football. The universe didn’t expand into anything, space was just expanding into itself.
