The Multiverse: Does it Even Exist?

A brief look into the idea of the multiverse theory.

When we look at the universe around us, we see an expansive field of space which is constantly growing. It’s estimated that from our fair planet to the edge of the observable universe, it’s 46 billion light years. That’s a lot of places for us to find life and generally explore.

When we watch science fiction shows like Star Trek or Stargate to name but a few, there’s always been those interesting few episodes which don’t take place entirely within the main “universe” of the show. In Star Trek we see this with both the Kelvin Timeline and the Mirror Universe, which while similar to the “Prime” Universe, they do have distinct differences. Stargate did this with a quantum mirror which allowed travel between these different realities, or in one instance, through the stargate itself due to the powers of a black hole.

These sorts of stories give us the scope for a much wider amount of storytelling as so long as it can be imagined, a story can be made alongside the main show itself. But how close to reality is this, or is it simply TV pseudoscience. Tegmark

physicist and professor at M.I.T.



There may be more to this than meets the eye as there are theories from actual scientists due to fields such as String Theory and Quantum Mechanics. These do suggest that there alongside our universe, we could have a multiverse, which could be virtually identical to what we have already. Max Tegmark, a mathematician and cosmologist from MIT has suggested there could be four different types of parallel universe.

The first one which is virtually identical to the universe that we currently inhabit with nothing new inside. This would likely be similar to what we’ve seen on Televisions.

The second may be similar but where the laws of physics as we understand them are different, which could open up some very interesting possibilities, maybe gravity works in reverse?

The third type is one which has a similar law of physics to what we have within our own universe, however it’s differentiation to the first is that the conditions at the start of the universe were different.

Finally, is a universe with the same laws of physics again but some of the bylaws that we have here are different.

While all of these do seem very similar, each one has a very unique take on what you’d see if you were to visit a universe which fit each of those descriptions. It’s hard to imagine what it’d look like, but perhaps the Mirror Universe fits into the final idea, as we did see that it was darker naturally within that space.Everett

proposed the 'Many Worlds
Theory' in 1957


While it is fun to postulate on whether these do exist and we could argue this for decades to come, one of the main questions becomes. If we can’t visit it, how can we be sure that it’s there? Perhaps that’s what some explorers or members of the public thought about America before it was discovered by the European explorers back during that period of time. How can they be sure that it’s really there.

Some scientists have been looking at ways to prove whether there are these parallel universes and have come up with some ideas. Both of these ideas stem from the cosmic microwave background which is what’s left over from the big bang. One of the suggestions is that these universes leave either hot or cold spots within this CMB which we can detect with some of the instruments that we’ve got now. Although nothing has been discovered as of yet.

The second idea, is through gravitational waves from the big bang which put “curls” into the CMB. These are then detected by our telescopes which has been done already, back in 2014, although I don’t believe anybody has used that to show a parallel universe yet.

It’s an interesting conundrum, for all we know there’s another UFP in another universe where Three has become the ultimate dictator, running the community with an iron fist with her cat by her side, although I’m not sure how I would feel about that.


Do you think that you’ve got a doppelganger out there somewhere, perhaps whose made a few different choices leading to a different future? I’d love to know what you all think.

I really loved this article and I’d love to see more like this! This is an area of great interest to me, I’ve always believed that every possible action, consequence, reaction can happen and does happen in alternate realities.

Its very similar to Quantum Super-positioning in Quantum Mechanics whereby something, whether it be an object, state of matter or whatever can exist in every possible form and version at the same time and only becomes one of those states once it’s observed. This could be applied to the ideology of a multiverse, whereby our actions as humans dictate what the outcome, consequence etc. becomes or happens and that a new reality or timeline is formed when a different action is taken.

For example, one day I turned left to walk down the street to go the supermarket for groceries. But what would have happened if I turned right instead? What possibilities could happen by me making such a simple decision? Thanks for writing such an awesome article!

I was meaning to reply to this earlier as I read your reply and I have to agree with you both on the grounds that it's a very interesting topic, as I'm the same, I find issues like this quite engaging as it does give you that scope to think, what if?

I think it would be both interesting but terrifying if we were able to look into these probable universes as how would we feel if we found that some decision we made led to us not being as successful or worse.

I do always wonder whether the human mind would be able to cope with that sort of conundrum as well.

Oh for sure! This sorta stuff is my jam haha, there might be a species or even several capable of perceiving this sorta thing, especially if you consider that time could be the 4th dimension. At our current stage of evolution I’d imagine that we’d simply be unable to perceive or even comprehend such things, perhaps our brains would react in some manner that would be detrimental to our survival. I know it sounds really cliche but total madness would be my expected outcome.

There are those that we believe we will one day evolve to the point were we can understand the nature of the universe as a single equation, so who knows what incredible discoveries are waiting to found out there.

What if you know you were going to get hit by a car tomorrow, naturally you’d take action(s) to avoid that but perhaps by doing that you end up getting hit regardless. Something Guinian said from best of both worlds seems apt here: “When a man is convinced he’s gonna die tomorrow, he’ll probably find a way to make it happen”.

I don't buy into the multiverse theory myself. The reason is hard to put into words but is related to my conviction that the current theory concerning quantum particles is fundamentally flawed and based on human arrogance. To assume that a particle is in more places at the same time because we do not know what position it is in is arrogance. If the method of observation influences the observed than the method of observation is flawed. The fact we have not found a way of observation that does not influence the observed does not mean there cannot be one, merely that we are YET unable to conceive of one.
Therefore if the quantum theory from which current quantum science derives the fundamentals of quantum mechanics has flawes on such a base level, the mutliverse theories that come from quantum therory cannot be considered at this time.

But that's just my opinion.

(...) especially if you consider that time could be the 4th dimension. (...)
Oh, and time does not exist. Time's merely a construct of the human mind, in my opinion.

Thank you for this article Chris, it was quite an enjoyable read. I appreciate that you have a clear and easily understandable manner of communicating complex concepts. If I had a doppelganger out there I would not want to know how they lived their life. I have played many many hours of RPG's and would spend the rest of my life wishing I could go back to an earlier save point and live my life differently using the guidebook equivalent of my other self.

On a side note, if it was a world ruled by Three, would she instead have a dog by her side???

The thing that messes with my head is the supposition that in fact you did turn right, went straight, went up, went down, got hit by a meteor,..etc. You did all these things and each exist in their own existence.

To believe that any of this is true, would have me believe that all of it, that in every moment, every possibility for every atom in existence would be played out and the consequences run their coarse into the next moment.

The numbers get mind boggling, but it doesn't mean things aren't running their course exactly as they should.
