The origin of the universe is the origin of everything. The universe is everything from the tiniest particles to the enormous structure like Hercules-Corona Borealis Great Wall and the very existence of space-time and life.
Multiple scientific theories plus creation myths from around the world have tried to explain it’s mysterious genesis.
Nevertheless, the most extensively count on explanation is the Big Bang theory.
The big bang theory states that the universe commences as a hot and infinitely dense point. Only a few millimetres wide it was similar to a supercharged black hole.
About 13.7 billion years ago this tiny little singularity violently exploded. And from this explosion all, that matter space and time were created.
Origin of the Universe
Then turn out two major stages of the universe’s evolution call the:
● Matter Era
They’re defined by key events that succour shape the universe.
First, the arrival of radiation era title for the dominance of radiation right after the big bang.
This era is made of smaller phases call epochs that occurred within the first hundred and
thousands years of the universe.
First came the plank epoch. Not a single matter existed in the universe at this time only energy and the ancestor to the four forces of nature super force existed.
At the end of this stage although a key event occurred in which gravity split away from the force.
Grand Unified Epoch
Next came the unification epoch named for the three remaining unified forces of nature.
This epoch breaks off when one of those forces call strong nuclear broke away.
Then this epoch initiate during which universe rapidly expanded. Almost instantly it extends from the size of an atom to the size of great fruit.
The universe at this time was piping hot and it churned with electrons quarks and other particles.
Origin of the Universe
In this last two forces electromagnetic and weak finally split off.
During this epoch, all of the universe’s ingredients were present however the universe was still too hot and dense for subatomic particles to form.
After that in the hadron epoch, the universe cooled down enough for quarks to bind together and form protons and neutrons.
Lepton Epoch and Nuclear Epoch In these two epochs which is last phases of radiation era. The protons and neutrons underwent a significant change.
They fused and created nuclei. And in doing so they created first chemical element in the universe call helium.
The universe’s new ability to form elements the building blocks of matter queued the matter era.
Much as the name suggests the matter era’s defined by the presence and predominance of matter in the universe. It features three epochs that span billions of years.
The vast majority of the universe’s life span and includes the present day.
The first was the atomic epoch. In this phase, the universe’s temperature cooled down enough for electrons to attach to nuclei for the first time called recombination.
This process succour creates the universe’s second element call hydrogen.
This hydrogen along with helium atoms dotted the universe with atomic clouds within the clouds small pockets of gas may have had enough gravity to cause atoms to collect.
All these clusters of atoms formed during this epoch. And became the seedlings of galaxies.
Nestled inside those galaxies stars began to form.
And in doing so they queued the latest and current stage of the universe’s development the stellar epoch.
The formation of stars then causes a tremendous ripple effect to help shape the universe as we know it.
The heat within the stars caused the conversion of helium and hydrogen into almost all the remaining elements in the universe.
In turn, those elements became the building blocks for planets moons life every possible thing we see today.
This all only been possible because of the many developing stages universe been through.
But whatever these theories say countless questions about the origins of the universe will remain leading to from where that first dense dot came from.
Why even anything exists? Just for a matter of time for the answer to emerge.
