When dimensions are mentioned we tend to think of portals through

other worlds, which will be only achievable in the future due to our limited

knowledge and use of the universe. But that is not true, in fact observation on

dimensions could lead us to the “Hyperspace” theory, which may be able to unify

all known laws of nature into one theory, the unification of all known physical

forces “the theory of everything”. But before getting to that, there is a need

for mastering the dimensions that we live in, and its characteristics. As we

are experimenting and measuring our way within our dimensions we reach a limit

which stops from going forward, higher dimensions, from this point on we can

only rely on math and our predications. Since we are prisoners of the third

dimension, and our minds are unable to imagine anything higher.

One physicist who delights in teasing audiences about the

properties of higher dimensional universe is Peter Freund, a professor of

theoretical physics at University of Chicago’s renowned Enrico Fermi Institute.

Freund states one of the reasons that higher dimensions were viewed skeptically

was that there was no way of measuring them and they also had no particular

use. But today scientists call our three-dimensional world too small to

describe the forces that govern our universe. For centuries, scientists

wondered why the four fundamental forces of nature are so different from each

other. Freund emphasizes that the laws of nature become simpler and more

elegant when expressed in higher dimensions, which is their natural home. Take

Electromagnetism for example, it includes electricity, magnetism, light itself,

compared to another fundamental force like gravity which is quite different,

but they are both necessary for our universe to exist, so there must be a

relation between. Hyperspace was proposed a as new theory of gravity in which

light could be explained as vibration in the fifth dimension. “Superstring theory”

took this even further, it predicts a precise number of dimensions for space

and time. Ten, this gives us the advantage to have enough room for all four

fundamental forces which are in their natural home and natural form. Hyperspace

is based of how things change as we change the number of dimensions, it is

clear an increase in dimensions is an increase in the quality we view the

universe in, this can be demonstrated by comparing our self to a two-dimensional

creature. For Hyperspace to be experimented, the ability to see higher

dimensions is needed. When Freund was asked why we can’t see these higher

dimensions, he responded with, because these higher dimensions have been “curled

up” into tiny ball so small that they can no longer be detected, according to

Freund the size of the of these curled dimensions is called Planck Length. He

believed dimensions get smaller as they increase, so we are tiny ball in a

two-dimensional world. There is still debate on this and its reasoning behind

it.

When searching up “Hyperspace” in a search engine it comes up with

pictures that look liked traveling through stars or in a portal, which is a

reference from a sci-fi movie, this is due to the fact there is no pictures of

Hyperspace or how it looks like, since we are unable to see. For a better

realization of higher dimensions best way is to look back at lower dimensions.

The world we live in contains 3 spatial dimensions (?3), this is

illustrated by looking at anything. Everything in this universe has a width,

length and a depth. No single object lacks any of this dimensions in our world.

Now what would happen if we lacked one of this in our universe, how different

would it look like? This is the two-dimensional world, or Flatland, creatures

of this universe can’t even eat since a digestive system would cut them in

half.

These creatures are prisoned by their two-dimensional world, a jail

in Flatland could be done by drawing a line around the criminal, no matter

which way the criminal moves, he hits the impenetrable circle. If a

three-dimensional was held in this jail, he could just walk over the line and

then he was free, in Flatland this would look like he disappeared for a second

and reappeared out of the jail. This is one of many the examples of our reach

in the second dimension. Now imagine the powers of a fourth dimensional being,

it would be like God-like powers in our perspective.

As we go up from zero dimension which is a dot to three dimensions,

the world gets more complex, to a point where the universe has not enough room

for its complexity, so there will be more than one universes. Multiverse, this

happens after fourth dimension which is time, most of the data on this part is

theoretical and is based of predication. Common say there is no use for this,

but this could be the only way to escape this universe, it is wise to say our

world will end one day, so the only way to save intelligent life is to move in

to another universe, a parallel one. How to travel to a different universe is

still a mystery, also there are really strange events that could happen in this

parallel universe, for example due to entropy, the number of different quantum volumes

(all different ways particles can arrange) a person is 10 to the power of 1070,

and let say an average human takes about 1m3 of space, now if this

parallel universe is far enough or even large enough for us to travel further

than 10 to the 1070 meters, we could see repetition of us. Identical

humans but in a different universe. This is the power of Hyperspace

At the end a there is this hypothesis that, a civilization with

access to Hyperspace technology could rule all the dimensions below it and

travel to the edge of the universe. But since most of the data is theoretical

and not experimental, not a lot of research is going through this subject, and

is commonly known as a reference from Sci-Fi comic books or movies. But it

might help us find the foundation of the forces that govern our universe and a

new era of civilization

This was all from part 1 and 2 of a book named “Hyperspace” by Michio Kaku which I read during the past

months.
