The theory of the multiverse suggests that our universe – the one that contains billions and billions of galaxies, planets, and stars – and extends tens of billions of light-years away; may not be the only universe to exist. 


What would you do if someone told you that there was potentially an exact copy of you in some other place – the same weight, the same age, the same size, and all the other attributes that make you unique but exactly the same?

What would be your reaction to two exact ‘copies’ of you somewhere out there? Or even three? Would you be excited or scared?

Whatever feeling this thought ignites in you, you’re sure to embark on a ride of your life in this article.

With this in mind, we are going to explore everything you need to know about the multiverse right here. 

Let’s get straight into it! 

What Is A Universe?

To first understand the complexities of the multiverse, we need to fully comprehend what the term ‘universe’ consists of. 

When thinking of the universe, many things come to mind, some would even say all things come to mind since that is what it essentially is: an all-encompassing entity.

From galaxies, stars, planets, and solar systems to humans, plants, animals, molecules, compounds, protons, electrons, and atoms – the universe is made up of everything in our realities. 

As you gaze up at the night sky, you’ll be able to see thousands of various stars and celestial bodies, sometimes, if you’re lucky, a galaxy or cluster, too. 

If you take things one step further and introduce a telescope into the mix, then you’ll be able to see celestial objects situated millions of kilometers away. 

With the most powerful instrument of observation, you’re even able to see the earliest stars in the universe and the remnants of the Big Bang. 

How Does The Big Band Interlink Here?

In terms of astronomy, the Big Bang is described as being the beginning point of the universe’s timeline.

According to the theory, the universe started at one point and expanded out to become what it is. In fact, it continues to expand today!

As such, when thinking about the universe, we typically consider the Big Bang – which occurred approximately 13.8 billion years ago – to be the starting point of everything. 

Although, what happens if the Big Bang didn’t influence the beginning of space and time, but only the starting point for our universe?!

What Is The Multiverse?

This is where the theory of the multiverse comes into play.

Here, the theory implies that our universe – the one which consists of billions and billions of galaxies, planets, and stars, and extends billions of light-years away – is not the only universe that exists. 

Somewhere, there could potentially be another universe completely the same but different from ours in terms of natural laws. 

Something that may even blow your mind further is that there may not only be one but an infinite number of such universes, too.

All of such universes differ from one another and contain millions of different celestial bodies, and potentially intelligent life forms, too – the same as our universe. 

Here, multiverse theory suggests that our universe isn’t the only universe to exist but it is a member of an infinite magnitude of universes. 

The multiverse is an idea that arose from the popular and widely known theory – the inflation theory. It was developed in 1980 and contributed information to the Big Bang where gaps were missing. 

While the Big Bang theory offers a reasonable explanation of the universe’s origins, there are three problems that it doesn’t explain.

Firstly, it doesn’t address the universe’s flat geometry. 

Plus, it doesn’t take into consideration the horizon problem and monopole issues interlinked with the universe.

Therefore, the theory doesn’t explain why the universe’s structure contains so much homogeneity. 

Multiverse Theories

Multiverse (1)

One of the most scientifically accepted theories comes from the concept of inflationary cosmology.

This is the idea that during the minuscule moments after the big bang, the universe was exponentially and rapidly growing. 

This theory helps to explain some of the observations in the universe, including the distribution of galaxies and their structure. 

One of the many predictions that came along with this theory was that inflation could take place over and over again in the universe – even infinitely!

This creates a constellation known as bubble universes. 

While these bubbles won’t contain all the same properties – physics may behave differently in some, others could be similar to our universe.

That said, they all exist beyond the realm of our observation. 

Is There Direct Evidence Of The Multiverse?

While there are particular features of the universe that would suggest the multiverses exist, there has been no direct observation that would suggest its existence.

Thus far, such evidence has only been theoretical and even philosophical. 

While some scientists believe that the Big Bang was the result of some grand cosmic coincidence that allowed our universe to become perfectly balanced, others believe that multiple universes exist, and ours simply contain the required characteristics for our survival. 

Some scientists even argue whether or not the multiverse could be an empirically testable theory.

Here, some people would attest that it isn’t since by definition the multiverse is dependent on our universe, thus, impossible to access. 

That said, maybe the correct tests simply haven’t been figured out yet. 

Final Thoughts

The sheer expanse of the universe can sometimes be difficult to deliberate and come to terms with. 

Although, with so much space, it’s hard to imagine humans are the only intelligent beings inhabiting space. 

This is where the idea of the multiverse comes from. Essentially, it suggests that multiple universes exist which may or may not contain similar characteristics to ours. 

Hopefully, this guide has informed you about everything you need to know about the multiverse.
