Hyperspace 1 of 2 – Michio Kaku and the 5th dimension

Unveiling the secrets of hyperspace: Michio Kaku explores the theory of additional dimensions.


Some people seek meaning in life through personal gain, through personal relationship, or through personal experiences. However, it seems to me that being blessed with the intellect to divine the ultimate secrets of nature gives meaning enough to life.” – Michio Kaku

1. The Hyperspace theory and its implications

Following Turok and Bohm mentioned in our last article on the universe (A crowded multiverse 2 of 2), another professor of even greater fame finds his rightful virtual speaking slot in this article: Michio Kaku. Here is a short biography extracted from his own website:

Dr. Michio Kaku— theoretical physicist, bestselling author, acclaimed public speaker, renowned futurist, and popularizer of science. As co-founder of String Field Theory, Dr. Kaku carries on Einstein’s quest to unite the four fundamental forces of nature into a single grand unified theory of everything”.

Most of us have had a chance to see an interview of him in a documentary, read one of his articles, see him on YouTube: he is up there in the Olympus of physics and science popularisers alongside Neil DeGrasse Tyson and Bill Nye.

In one of his 19 books, Hyperspace, Michio Kaku warmly advocates the theory of the existence of multiple dimensions in our universe. A theory that is about 100 years in the making, and nowadays it is central to several physics unification theories. According to it, further dimensions of space would solve doubts and conundrums that are still afflicting academics and keeping humanity at its infant stage.

In this book Michio Kaku illustrates the additional dimensions

More specifically, if more dimensions of space were to exist, obviously beyond the three we can see, touch and feel, popular incompatible theories of physics would merge beautifully: classical physics, the standard model and quantum physics. What is more, the force of gravity would be fully explained, we could access incredibly higher levels of energy due to our expanded understanding of the universe and we would be in a position to either be openly and officially contacted by aliens or be able to travel to find them.

The idea of multiple additional dimensions that Michio Kaku defines as Hyperspace is therefore critical for humankind for a number of different reasons. If it were to be confirmed and discovered, we would experience a giant leap forward in our evolutionary path.

While we absolutely recommend you to read Hyperspace yourselves, we would like to inspire you with some key concepts expressed in it.



2. The carp world

Michio Kaku illustrates the theory of additional dimensions by starting by drawing a parallelism between how we as humanity versus how a group of carps in a pond experience life with the purpose of illustrating the limits that preclude us to perceive other dimensions.

Professor Kaku imagines how a group of carps living in a pond within the Japanese Tea Garden San Francisco go about their life with the main assumption that their reality consist of murky water and lilies. There would be no scientific reason for them to imagine the existence of a parallel universe beyond their own. Why, if they cannot see it? The nature of our world would be beyond their comprehension. The thinnest barrier, the water’s surface, separate both worlds thus being in effect an immense chasm.

Concepts like rain and wind moving the lilies would be impossible for them to know and grasp. Kaku continues the symbolic fable imagining the existence of “carp scientists”. These would probably invent concepts like invisible forces to justify the effects visible to them and their species, like wind and rain.


Here his powerful conclusion: if our scientists invent concepts like forces, it is only because they cannot visualize the invisible vibrations that fill the empty space around us. Kaku is convinced how these invisible vibrations must be coming from other dimensions.

Unfortunately some scientists sneer at the mention of higher dimensions because they cannot be conveniently measured in the laboratory: “for several thousand years, mathematicians would repeat this simple but fatal mistake, that the fourth dimension cannot exist because we cannot picture it in our minds”.

Luckily, Michio Kaku embraces science and is still able to dream, exactly like us here at eXtraHumans – Hyperspace theory 



3. Visualizing the 5th dimension

Our reality is made of 3 dimensions of space and 1 of time and by providing those coordinates we can pinpoint a place anywhere in the universe.

German mathematician Georg Bernhard Riemann was the first to lay the mathematical foundation of geometries in higher dimensional space. He demonstrated that universes made up by 5 or more dimensions are self consistent and obey their own inner logic.



Most of us would wander: how does the 4th spatial dimension look like? In which direction should we start to imagine objects protruding into the 4th dimension? What tips or hints can we get to start imagining it?

The truth is, it is impossible for anyone to visualise the 4th spatial dimension. Many scientists and believers have tried to picture it, but each of them has hit the ceiling represented by a reality limited by 3 spatial dimensions. Georg Bernhard Riemann and all following scientists dedicated to the hyperspace theory have been able to map additional dimensions exclusively mathematically.

While wallowing in our disappointment for feeling that any further dimensions remain beyond our grasp, Plato’s words echo eerily through the centuries when he stated that we are exactly like cave dwellers, forever destined to observe shadows as opposed to real objects. Is the limitation of 3 spatial dimensions connected to an illusory reality? In future articles we will expand both Plato’s cave allegory as well theories about our reality.



4. Kaluza the pioneer and the hyperspace theory

As we have seen in our article The quantum foundation, Einstein showed that the known dimensions (3 of space and 1 of time) could be unified in a 4 dimensional theory that led to the unification of space and time, matter and energy.

Einstein in fact unified space with time (the faster you travel you slower you go) and matter with energy (all matter can be converted to an incredibly high amount of energy).

Ultimately he combined the newly discovered entity “spacetime” with the interchangeable combination “energy-matter”, whereby energy-matter have an impact on how spacetime is shaped.

That was obviously an incredible breakthrough for humankind, however it is not sufficient to explain our reality as a whole since, for example, it does not match the quantum mechanics theories and discoveries.

Einstein was looking for a theory of everything but failed to find it. Then Kaluza, an unknown mathematician, proposed the unification of Einstein theory of gravity with Maxwell’s theory of light (2 diametrically different forces both mathematically and in the real world) in an equation that included 5 dimensions instead of 4.

What you will hear over and over again from all corners of physics is that a theory of hyperspace is clean, beautiful, majestic because it simplifies the laws of nature, and under it all forces of nature can be united marvelously well.

What to expect in the next and final section: Michio Kaku reveals how light is an evidence of the existence of the 5th dimension; also, we consider the implications of additional dimension on the existence of and in establishing a connection with other intelligent beings


“...the “Mind of God,” which Einstein wrote eloquently about, is cosmic music resonating throughout hyperspace.” – Michio Kaku
