THE UNIVERSE AND ITS CREATION
The desire to know how things are made and why everything is the way it is has always fascinated humans and all species alike...
I am going to try and walk you through how it all started...The Universe..hope you enjoy the ride...

Well there is the obvious philosophical standpoint and a religious standpoint that what we have was a creation by God or a higher power...which is debatable but the fact that we haven& #39;t found how something was made out of nothing makes this plausible and open to intepretation...
Now, to the theories researchers have spent entire lives on:
In the 1940s a competing hypothesis arose, called the Steady State theory.British astrophysicist Fred Hoyle and others argued that the universe was not only uniform in space—an idea called the cosmological principle—but also unchanging in time
Quick note:cosmological principle basically means that when viewed on a large enough scale, the properties of the universe should not show any irregularities as it was perceived by some scientists that out universe was in fact a constant entity and not ever changing as we know it
Here is why this theory fails though: Astronomers can figure out how old a galaxy or star is by measuring its distance from Earth. The farther away from Earth an object is, the longer it has taken light from the object to travel across space and reach Earth.
This also means that the most distant objects we can see are also the oldest. This was conclusive proof that steady state theory was not the ultimate truth to the creation of the universe.
The reason why I mention this theory is that only when we see and understand failures and attempts will we know the real value of the achievement

The best-supported theory of our universe& #39;s origin centers on an event known as the big bang..
This theory was born of the observation that other galaxies are moving away from our own at great speed in all directions, as if they had all been propelled by an ancient explosive force.
We know the theory, but maybe not the person..this theory was first proposed byA Belgian priest named Georges Lemaître first suggested the big bang theory in the 1920s, when he theorized that the universe began from a single primordial atom.
The idea received major boosts from Edwin Hubble& #39;s observations that galaxies are speeding away from us in all directions
as well as from the 1960s discovery of cosmic microwave radiation,which are perceived to be remnants of the electromagnetic radiation from the early stages of the universe—by Arno Penzias and Robert Wilson.
Adherents of the Big Bang believe that this small but incredibly dense point of primitive matter/energy exploded. Within seconds the fireball ejected matter/energy at velocities approaching the speed of light.
At some later time—maybe seconds later, maybe years later—energy and matter began to split apart and become separate entities. All of the different elements in the universe today developed from what spewed out of this original explosion.
In the first 10^-43 seconds of its existence, the universe was very compact, less than a million billion billionth the size of a single atom. It& #39;s thought that at such an incomprehensibly dense, energetic state, the four fundamental forces...
Gravity, electromagnetism, and the strong and weak nuclear forces—were forged into a single force, but our current theories haven& #39;t yet figured out how a single, unified force would work. To pull this off, we& #39;d need to know how gravity works on the subatomic scale, which we don& #39;t
It& #39;s also thought that the extremely close quarters allowed the universe& #39;s very first particles to mix, mingle, and settle into roughly the same temperature. Then, in an unimaginably small fraction of a second, all that matter and energy expanded outward more or less evenly,
As time passed and matter cooled, more diverse kinds of particles began to form, and they eventually condensed into the stars and galaxies of our present universe..
By the time the universe was a billionth of a second old, the universe had cooled down enough for the four fundamental forces to separate from one another. The universe& #39;s fundamental particles also formed. It was still so hot, though, that these particles hadn& #39;t yet assembled yet
As the universe kept expanding, this piping-hot primordial soup—called the quark-gluon plasma—cooled down and even today as the universe expands this keeps going and we are amazed everyday
On a personal note here: The concept of something from nothing and the fact that everything we have and see now also had a starting point is something that has always fascinated me...
We still have a long way to go in terms of finding out the entire truth to the origin of the universe and new theories are bound to arise which give us a better understanding...but in all this prospect of the origin of the universe is very fascinating...
That& #39;s all I have for you today..
I hope you enjoyed this trip through the universe as much as I did while writing this..so until next time...
