Have you ever thought that we might be living in higher dimensions without being aware of it? So are we really living in higher dimensions or hyperspace? We may not be able to perceive higher dimensions because of the limitations of our senses and also the limitations of our brain.
To support my idea let me give you few analogies and examples...
As we know we have five senses in our body. We use these five senses to collect information from our surroundings. Using different senses we can see, hear, smell, taste or touch the outer world.
The information gathered by the senses is processed by our brain and we get some useful information from this raw data.
You can think of the senses of our body as the sensors used in measuring instruments and our brain as the processing unit of random and raw information.
We have two cameras in the form of eyes to see the outer world, two sound sensors (ears) for hearing the surrounding sounds. Our skin acts as the touch sensor that we use to feel the outer world. We can sense hardness, softness, humidity and temperature of the surrounding things.
In the same way we also have sensors for smell and taste in the form of our nose and tongue respectively.
we have other sensors in our body like pressure sensors, pain sensors, color sensors, orientation or balancing sensors, motion sensors, various chemical sensors, radiation sensors and many more.
But what I want to let you know is; that all the sensors that our body has; have their own limitations.
They have their working ranges. Out of this range they can not work, just like any measuring instrument.
For example- Human visual sensors that is our eyes, can see only in the visible spectrum range of the Electromagnetic wave spectrum.
Our visual sensors are not capable to perceive the world that contains other lower frequencies like infrared, microwaves or radio waves and also the higher frequencies like ultraviolet, x rays or gamma rays.
If someone strongly believes only on what his or her eyes see, then it does not mean that the world that he can not see, doesn't exist. A hidden world with much larger range of frequencies still exists, whether humans eyes can perceive it or not, doesn't matter. This is simply the limitation of our visual senses.
But we can still detect and see these frequencies with the help of our scientific instruments. Some animals like snakes can sense the lower frequencies of the infrared radiation just like an infrared camera.
In the same way bats can hear ultrasonic sounds that are impossible to hear for our hearing sensors. We can hear only within the range of 20 Hz to 20kHz. But bats can hear well up to 113kHz.
So it may actually be possible that we are already living in a universe of higher dimensions but because of the limitations of our senses and our intelligence, we are incapable of perceiving the higher dimensions.
But why we cannot perceive the higher dimensions?
Actually higher dimensions are curled in on themselves in a process known as compactification.
So we can only perceive three dimensions of space called as length, breadth and height and one dimension of time where we can move only in the forward direction.
Now I will explain with the help of an example, how we will find higher dimensions on changing our viewing reference frame and on going into microscopic level.
Suppose there is a rope tied between two rocks and you are looking at it from a distance. From your frame of reference, the rope is one dimensional (length). But now imagine, there is an ant crawling onto the rope. It can definitely see at least two dimensions. The ant can move not only along the length of the rope but also along its thickness. It can also see the roughness and grooves of the rope. So from the ant's reference frame, the rope is not just one dimensional as it can see other dimensions too.
Now if we enter into the rope for more details, at the Microscopic level of atoms, then we will find that from the reference frame of tiny atoms the rope is three dimensional. It has large number of atoms arranged in a 3D pattern and each having solid nucleus and electrons that revolve around it in 3 dimensional space.
On going further at extremely small level we will enter into the world of strings. These strings vibrate in 11 dimensions. According to the string theory, everything in this universe is made up of tiny vibrating loops known as strings. Vibrations of the strings are responsible for the mass and other properties of a matter.
Hence we have seen that a simple rope may appear one dimensional for you from some distance, two dimensional to an ant, three dimensional at the atomic level and even 11 dimensional at the level of strings. All depends on the frame of reference and at what microscopic level we are observing.
So it will not we wrong to say that we might be living in a world of higher dimensions unknowingly. For this, we can blame our limited intelligence and limitations of our senses.
