Epsilon used knowledge from Earth to create the Dimensional Wave Reader. It was not like the knowledge he used was specifically relevant to understanding dimensional waves themselves. In fact, he wanted to use dimension related knowledge to create this metal orb that he named ‘Dimensional Wave Reader’.

The Dimensional Wave Reader was a gadget that could read dimensional coordinates and dimensional waves. This reading ability made the user of the Wave Reader capable of pinpointing the location they were searching.

In most cases, these kinds of magical items were not seen as too useful. The Dimensional Wave Reader, however, was important to the point that not everyone could represent or copy it. The number of dimensions, planes or planets were infinite. However, this product could locate the target dimension. With details of the target dimension added, this was a life-saving item that served a more important purpose than several other things.

*‘Dimensional Wave Reader’*

*‘Class – Item’*

*‘Description’*

*‘An item of dimensions, created by mage ‘Epsilon’. It lets its user pinpoint the location of a dimension if the details and knowledge about the target location are detailed enough.’*

*‘Price’*

*‘10 Void Stones – 10 Million Ether Stones’*

Epsilon was very pleased when he saw the value of the Dimensional Wave Reader. Of course, he was not considering selling this item as it was stronger and more valuable, which in turn could bring him troubles that were not worth the price it could be traded on.

The knowledge Epsilon used for creating Dimensional Wave Reader was ‘Five-Dimensional Space’.

*‘A five-dimensional space was a space with five dimensions. In mathematics, a sequence of N numbers could represent a location in an N-dimensional space. If interpreted physically, that was one more than the usual three spatial dimensions and the fourth dimension of time used in relativistic physics. Whether or not the universe was five-dimensional was a topic of debate.’*

*‘The fifth dimension was a micro-dimension which was accepted in physics and mathematics. It’s here to have a nice and seamless tie between gravity and electromagnetism or the main fundamental forces, which seemed unrelated in the regular four-dimensional spacetime.’*

*‘In this case, a fifth dimension would be an extra dimension of space. Such a dimension was proposed independently by physicists Oskar Klein and Theodor Kaluza in the 1920s. They were inspired by Einstein’s theory of gravity, which showed that mass warped four-dimensional space-time.’*

*‘Their model had the familiar four dimensions floating in an infinitely large, negatively curved fifth dimension. While the electromagnetic and nuclear forces were stuck inside a ‘brane’ made of four dimensions, gravity leaked out into the fifth. ’*

A five-dimensional space was a space with five dimensions. If interpreted physically, that was one more than the usual three spatial dimensions and the fourth dimension of time used in relativistic physics. It was an abstraction that occurred frequently in mathematics, where it was a legitimate construct.

Much of the early work on the five-dimensional space was in an attempt to develop a theory that unified the four fundamental interactions in nature: strong and weak nuclear forces, gravity and electromagnetism.

German mathematician Theodor Kaluza and Swedish physicist Oskar Klein independently developed the Kaluza–Klein theory in 1921, which used the fifth dimension to unify gravity with electromagnetic force.

Although their approaches were later found to be at least partially inaccurate, the concept provided a basis for further research over the past century. To explain why this dimension would not be directly observable, Klein suggested that the fifth dimension would be rolled up into a tiny, compact loop on the order of 10-33 CM.

Under his reasoning, he envisioned light as a disturbance caused by rippling in the higher dimension just beyond human perception, similar to how fish in a pond could only see shadows of ripples across the surface of the water caused by raindrops.

*While not detectable, it would indirectly imply a connection between seemingly unrelated forces. Kaluza-Klein theory experienced a revival in the 1970s due to the emergence of superstring theory and supergravity: the concept that reality was composed of vibrating strands of energy, a postulate only mathematically viable in 10 dimensions or more. Superstring theory then evolved into a more generalized approach known as M-theory.*

*M-theory suggested a potentially observable extra dimension in addition to the 10 essential dimensions which would allow for the existence of superstrings. The other 10 dimensions were compacted, or ‘rolled up’, to a size below the subatomic level.*

Epsilon wrote many kinds of knowledge about the Five-Dimension theory. To finally get to the Dimensional Wave Reader, he had read all of them before he got up from his chair to leave the office.

As soon as he stepped into the common area, he saw many researchers were still busily working on how they could find the dimension.

It was evident that should the Underbroom Cave not have this natural dimensional rift or gate, the Werfurs would have no chance to teleport or transport to the other dimensions.

Using the Underbroom Cave’s natural dimensional rift as a case, they would try to find an idea that would let them use or create a dimensional gate everywhere.

Of course, right now they were reaching nowhere with this. They did not even have the means of finding the target dimension, opening a dimensional gate everywhere was not something that looked achievable for them at the moment.

Rabial came to Epsilon’s side to give him food. The latter took this time to talk to him.

“I completed the task of creating and building a ‘Dimensional Wave’. Essentially, pinpointing the target dimension will no longer be a problem for us as long as we have a gadget or person who can control a dimensional gateway or create it. For now, we can use my gadget to open a dimensional gate to the ‘Greenland Continent’.”

Rabial’s breath hitched as soon as he heard this but he was not shocked in the least. From the moment he has been with Epsilon, the human mage always did something that was otherwise considered unattainable or even impossible for many.

Using his magical energy to make his voice loud enough so that it reached every corner of the Underbroom Cave, Rabial made an announcement.

“The researcher Epsilon has found a way to pinpoint the target dimension. From now on, we only have to build a gadget or a spell to control the gateway and then we can travel to the Greenland Continent.”
