How to Visualize Higher Dimensions - Dimensions Explained - How to Draw Dimensions

Do you know that we can visualize higher dimensions by drawing them on a sheet of paper. Here I have explained higher dimensions starting from the Zero Dimension (0 dimension) to the Eighth Dimension (8th dimension) by Drawing the dimensions. You can use the same technique to draw further higher dimensions.

This video explains 0 dimension, 1st dimension, 2nd dimension, 3rd dimension, 4th dimension, 5th dimension, 6th dimension, 7th dimension and 8th dimensions.

How to Visualize Higher Dimensions Video

Let's begin our journey of explaining and drawing from zero dimension to eighth dimension. We will start with the Zero (0) dimension. Here on the screen we have a single point having no length, no width and no height. As it has no dimension, it is called as the zero dimension. Now if we double the number of points then we enter into a one dimensional (1st dimension) world having only 1 dimension i.e. length. So in the first dimension we only get a straight line having no width or height. Now let's double the points again and this is, what we call as the second dimension (2nd Dimension). Observe here it has only two dimensions length and width. So it is a plane surface having no height or depth dimension. To enter into the third dimension (3rd dimension) let's again double the points and we get the third dimension. As you can see here, the third dimension contains 3 dimensions which are length, width and height. On adding third dimension I.e. height to the second dimensional plain object, they become the third dimensional solid objects. We all live in a three dimensional world. Now to draw and understand the fourth dimension (4th Dimension) we again need to double the points and here we are in the fourth dimension. Observe carefully that to draw fourth dimension we need to join respective points of both the cubes which are three dimensional objects. Now let's repeat the process of doubling the points to enter into the next higher dimension. So to draw the fifth dimension (5th Dimension) all you need to do is just double the number of points that we used to draw the fourth dimension and join the similar points respectively as shown in the video and you will know how would the fifth dimensional space look like. By continuing the same process of doubling the points of a dimension, we can draw the next higher dimensions. Although the concept of drawing the next higher dimension is easy but as you can see here, it becomes more and more complex as we continue. So here for drawing the Sixth dimension (6th dimension), Seventh dimension (7th dimension) and Eighth dimensions (8th Dimensions). I am just showing you the doubling of points only without joining the lines as it would be too complicated and messy for me to draw and also for you to understand. As you now know how to do it so You can do it by yourself for fun. So friends I hope you enjoyed learning how to draw any dimension just by following a simple rule of doubling the points. #Dimensions #VisualizeDimensions #DrawDimensions

Higher Dimensions Explained - 11 Dimensions Explained - All Dimensions Explained

If you want deep understanding and visualization of all the dimensions starting from 0th dimension to the 11th dimension, then you have come to the right place.
As you will continue to read the article; you will understand- what are dimensions, how many dimensions are there according to different theories, how we can visualize higher dimensions and what is the geometrical structure of higher dimensions.
Here I will also explain why we are not able to perceive higher dimensions although we might be living in higher dimensions unknowingly and what supernatural powers a being of higher dimensions would possess.
So please go through this post till the end as most of your questions related to dimensions will be answered here.
First of all let's understand what we mean by dimensions?

What are Dimensions?

Dimension of a point is defined as the minimum number of coordinates that are needed to specify that point in it.
For example, to specify a sheet of paper we need two coordinates only; length and breadth. Therefore it is a two dimensional object.
But to specify a cube in space 3 coordinates are needed these are- length breadth and height. Therefore we call it a three dimensional object.

How many dimensions are there in the universe?

According to classical physics there are 3 dimensions of space; length, breadth and height and one dimension is of time. String theory requires 10 dimensions but as per M theory total no. of dimensions are 11. In Bosonic string theory spacetime is 26 dimensional.

Why we cannot perceive higher dimensions?

Actually We might be living in higher dimensions without being aware of it. But because of the limitations of our brain and senses we may not be able to perceive them.
According to some researches extra dimensions may be "curled up" at extremely small scales. This scale is so small that we can not see them with our experiments based on current technologies. As we live in a three dimensional world, it's very hard for our 3 dimensional brain to visualize higher dimensions.
There is a process known as compactification, where higher dimensions are curled in on themselves. On changing our reference frame and going into microscopic level we will find higher dimensions.
Let me explain it with the help of a simple example-
Suppose we are looking at a rope from some distance which is tied between two rocks. From this distance we will see only one dimension of the rope i.e. length. Now Imagine that an ant is crawling onto the rope. So from the frame of reference of ant, the rope is at least 2 dimensional as it can see it's breadth and thickness also along with its length. The ant can also feel the grooves and roughness of the rope.
If we go to microscopic level and see from the reference frame of atoms then we will see a whole new world of 3 dimensional atoms having solid nucleus and electrons revolving around it in 3 dimensional space.
On going further into the microscopic level of strings inside the atom, we will see that strings are vibrating in 11 dimensions. Everything in this universe is made up of tiny vibrating loops known as strings according to string theory.
So now you can understand how we can find higher dimensions at the microscopic level.

11 Dimensions Explained Video


 

Now I will discuss every dimension, starting from the zero dimension to the eleventh dimension.

0th Dimension (Zeroth Dimension)

There is no length, no breadth and no height of an object in the zeroth dimension. Example of zeroth dimension is a point.
Lets imagine someone is living in the zeroth dimension then he would neither have any body nor any shape. He can not move in any direction like forward, reverse, up or down. zeroth dimension is the basis of all the higher dimensions.

1st Dimension (First Dimension)

An object in first dimension has only one dimension i.e. length. A straight line is an example of first dimensional object. We can get straight line by joining two points.
A one Dimensional being can move only in a straight line. It cannot move in other dimensions like left, right and upward or downwards directions.

2nd Dimension (Second Dimension)

Second dimensional objects also known as two dimensional or 2D objects are flat shapes. Some common examples of two dimensional shapes are squares and triangles.
As the name denotes, two dimensional objects are made up of two dimensions length and breadth. There is no third dimension of height or depth. Therefore these objects are flat figures having non zero area but zero volume.
If someone is living in two dimensions, then he would be able to move only on a surface without being able to move in up or down directions.
He will not have any idea of the third dimension which is height.
Can you imagine what will happen when a 3 dimensional object enters into the world of two dimensional being? Let's understand it with an interesting example.
Suppose a two dimensional being present in his two dimensional space is watching a three-dimensional apple entering into his flatland world on a vertical axis perpendicular to the plane of the flatlander.
But as we know a two dimensional being cannot see a three dimensional object. So how would that 3 dimensional apple look like from the frame of reference of that flatlander?
He can not see the Apple until it touches his 2 dimensional plane as it's above his flatland and he cannot see anything which is above or below his 2 dimensional plane world.
but as the Apple just touches the plane, he will see a dot which is nothing but the point of contact of the Apple to the plane.  Now as the Apple goes below his plane world, he sees a circle growing in size on his plane and the size of the circle is maximum when half of the Apple is Above and half is below the plane and then the circle size becomes smaller and smaller and then a point and finally it disappears for him.
It means the 2 dimensional being sees only the cross sectional view of the Apple that is cut by his 2 dimensional plane at that moment.
So for a person living in a particular dimension, objects of higher dimensions suddenly may appear from nowhere, may change shapes and size and then disappear into space. It may appear supernatural or kind of magic for a lower dimensional being but for that higher dimensional object it's nothing special. It just moves in dimensions that are not perceived by him.

3rd Dimension (Third Dimension)

On adding one more dimension to 2 dimensional objects we enter into the world of three dimensions. This third dimension is of height.
Therefore to represent three dimensional or 3D objects we need three coordinates length, breadth and height.
As we have Already discussed that two dimensional objects are plane figures therefore have zero volume.
But three dimensional objects are solid objects and therefore have non zero volume.
Some common daily life examples of three dimensional things are balls, chair, car and we humans.
We live in a three dimensional world. This is the reason we can move in forward, reverse, up and down directions easily.
as we have full control over the three dimensions of space.

4th Dimension (Fourth Dimension)

Time is considered the fourth dimension. A four Dimensional being can move freely in time dimension. It would have full control over time. He would be able to move in any desired direction in time; past or future.
Suppose you are living in a four dimensional world then you would be able to go to a certain point in time in past and change your decisions.
But we humans are 3 dimensional beings, therefore have full control over the three dimensions of space but we are forced to move only in one direction in time; the forward direction, as we are three dimensional beings.
But if we consider the fourth dimension from the geometrical point of view then Hypercube is a 4 dimensional object. It is also called a Tesseract.
The relationship between a hypercube and a cube is same as that of cube and square. So in simple terms a hypercube or tesseract is four dimensional analog of the cube.
As a cube has 6 square faces, in the same way hypersurface of a tesseract consists of 8 cubical cells.

5th Dimension (Fifth Dimension)

A person living in 5th dimension can control time in different ways. A fifth dimensional being can move either in past or future as per his wish.
He would have all the powers that are possessed by a fourth dimensional being.
But he would also be able to be present at different locations at the same time. It would also be possible for him to do many jobs and have different hobbies simultaneously.
Actually Parallel universes exist in this dimension, therefore in the fifth dimension you can I have careers in different fields. In this case, you will have another versions of yourself in parallel universes who would be living their lives independently. They would have separate timelines for the parallel universes. Their lives in different parallel universes will be based on cause and effect. It means their lives will change as per the decisions made by your self versions in different universes.
But one limitation of fifth dimension is that you cannot meet your self version in directly using shortcuts to another timeline of parallel universe.

6th Dimension (Sixth Dimension)

A six dimensional being has all the powers that a person living in 5th dimension has along with some extra capabilities.
Parallel universes exist also in the 6th dimension. A six dimensional being can see all the presents, pasts and futures of all the parallel universes.
But one limitation of the sixth dimension is that all the parallel universes must have the same beginning (initial conditions) that is the Big Bang.
Like in the fifth dimension, in the sixth, dimension also you are free to choose multiple careers of your choice and your multiple versions can live their lives simultaneously in parallel universes.
As I already discussed, one problem with the fifth dimension was, you can not meet your self version in another parallel universe directly using shortcuts.
But the sixth dimension is free from this limitation. You can easily jump from the timeline of your universe to any point present on the timeline of any parallel universe.

7th Dimension (Seventh Dimension)

Seventh dimension can have infinite number of universes. A seventh dimensional being can have infinite forms of itself and can move from one universe to any other universe.
All the powers are possessed by a 7th dimensional being that a sixth dimensional being has.
The seventh dimension is free from the limitations of the sixth dimension.
The 7th dimensional universes may have originated from different start conditions.
And a person living in the seventh dimension can have infinite forms of itself which are able to move freely between all the infinite number of universes at his will. These infinite number of universes may have originated from different initial conditions not just the big bang.

8th Dimension (Eighth Dimension)

The eighth dimension has a plane of all the possible presents, pasts and futures for all the infinite number of parallel universes and all these infinite universes extend up to infinity.
String Theory says in the eighth dimension objects do not have any physical existence. You may think of it analogous to our digital world, where we can not touch the objects but only can see or hear them. They can change shapes, size and appear or disappear instantly. So it may be somewhat similar to the virtual reality.

9th Dimension (Ninth Dimension)

Infinite number of universes exist in the ninth dimension. It is possible for the universes in the ninth dimension to have their own laws of Physics and separate conditions and probabilities of their origin.
You will be surprised to know that in the ninth dimension many civilizations or aliens may live simultaneously at the same place. These coexisting civilizations may not see or feel the presence of each other.
The ninth dimensional being would have mind boggling super powers. That being would be capable of going to any point in time- past, present or future of any infinite number of universes.
He would have no physical form and would be able to move freely in space and time in any of the universes.

10th Dimension (Tenth dimension)

The 10th dimensional being would have infinite powers. He would be able to do  the things that are beyond your imagination.
He would be able to control even the spacetime and everything present in all the infinite number of universes.
So what would you call that 10th dimensional being who is infinitely powerful.
I think we can call him The God!!!
Some researches also suggest that God lives in the 10th dimension.

11th Dimension (Eleventh Dimension)

Many unanswered questions were arised when the superstring theory was introduced. Therefore to answer these questions, eleventh dimension was proposed by the researchers.
We can observe only three dimensions of space and One dimension of time. It is not possible for us to observe higher dimensions as higher dimensions are Compactified or curled up.
According to superstring theory, everything in the universe is made up of one dimensional and infinitely small vibrating loops called strings.
Even the subatomic particles are made up of Strings and unique characteristic of each subatomic particle is because of the manner in which the strings vibrate.
It is interesting to note that, frequency of vibration of the string is responsible for the mass of the particle.
But the string theory does not answer two important questions related to strings, what these tiny strings are made of and where they come from.
Size of the strings is of the order of 10^(-33) cm. This size is unimaginably small. This is many times smaller than the diameter of the nucleus.
10^-33 cm is actually millionth of a billionth of a billionth of a billionth of a centimeter.
I know Without giving an analogy our brains can not understand, how small this number is.
If we increase the size of an atom up to the size of the observable universe, then the size of the string would be just equal to a tree.

My dear friends this was all about 11 dimensions. I hope I could answer most of your questions regarding dimensions.

Origin of the Universe - The Big Bang Theory, Evolution and Timeline of the Universe

The video explains How the universe was created. This documentary is based on Origin and evolution of the universe. You will know how the universe came into existence 13.7 billion years ago after the big bang and before the big bang our universe was just a singularity but within fractions of a second the universe grew tremendously.

This all has been explained in the video as timeline of the universe from its beginning to the present time. There was no time or space before 13.7 billion years ago. Suddenly NOTHING changed into EVERYTHING.

The BIG BANG

The universe came into existence with Big bang around 13.7 billion years ago. Actually nothing existed before the big bang not even the time. Contrary to common belief, big bang was not really an explosion. In big bang the space itself expanded. The Big Bang model states that before the big bang, the whole universe was in the form of a point of infinitely small size, infinite density and also infinitely high temperature. This is called as the Singularity.

Origin of the Universe Video

Cosmic Inflation Era

Within first millionth of a trillionth of a trillionth of a second after the big bang, the universe grew really big!!! There was an exponential expansion of the universe in this extremely small span of time. This inflation era lasted from 10^-36 seconds to around 10^-32 seconds only. Therefore this phase of the universe is known as the Cosmic Inflation era.

Formation of the First Atoms

A few milliseconds after the big Bang the temperature of the universe was about 5 trillion degrees Celsius. At this level of temperature elementary particles like Quarks and Gluons mixed up to form a soupy primordial fluid that spread throughout the cosmos. Protons and neutrons are made up of Quarks and...Gluons act like glue to combine Quarks together so that protons and neutrons can be formed. When the universe was just 3 minutes old, Protons and neutrons fused together. This fusion process formed an isotope of hydrogen called as deuterium and also helium. But this process stopped as the temperature decreased. Finally after 380 thousands years after the big bang the temperature dropped to a level that was suitable for hydrogen and helium to combine with free electrons and in this way first neutral atom came into existence.

The Dark Ages

This was a very long duration of time that lasted nearly 100 million years, when there was no source of light in the universe. Therefore we call it The Cosmic Dark Ages. As most of the knowledge about the universe is obtained almost entirely from the light of stars, this makes it very difficult to get insight into this phase of the universe where stars were yet to form.

Formation of Stars

After the long dark ages, formation of stars started in the universe. This phase started by around 180 million years after the big Bang and continued for around 500 million years after the beginning of the universe. Because of gravitational force clouds of gases were pulled together and formed large sized spherical structures. At high enough temperature and pressure in the core of the spherical shapes, fusion reactions were triggered. In the fusion reaction two atoms of hydrogen fused together to form a single atom of helium. The fusion reactions in the stars generated large amounts of energy that lit up the universe. With the passage of time our universe filled with such shining stars. This stage in the evolution of the universe is known as the 'Cosmic Dawn' or 'reionization'.

Merging of Galaxies and Formation of Black Holes

Large sized galaxies started to form by the merger of smaller galaxies. Nearly 1 billion years after the big bang, supermassive black holes formed at the centers of the galaxies. Galaxies also grouped together due to attractive force of gravity and formed galactic clusters containing hundreds to thousands of galaxies. The brightest things in the universe was also formed called as Quasars. In this way the universe continued to evolve for billions of years.

Birth of the Solar System

Nearly 4.5 billion years ago clouds of gases collapsed down in a galaxy known as the Milky way. In this galaxy formation of a medium sized yellow star (Sun) took place under the influence of attractive force of gravitation. The star having 9 rings around it coalesced into 9 planets. The 3rd planet from the Sun was at the right distance from it that provided suitable conditions for the life to flourish. That planet was our home planet, the earth. Here on our planet different types of life forms evolved ranging from microbes and tiny creatures to gigantic Dinosaurs. As time passes various other species of plants and animals also appeared on the planet. And finally about 200 thousands years ago from the present time, the most intelligent life...humans evolved on earth. So this was the journey of our universe from its beginning to the present time.

String Theory for Dummies - String Theory - String Theory Explained

We will discuss here- What is string theory, what are strings in string theory and how small are these strings. We will also answer, Why string theory is so important and how it has proved promising in answering the deepest questions in fundamental physics.

What are Strings in String Theory

Before the introduction of string theory, it was considered that the fundamental particles of the nature are point like particles. But according to string theory it is not true. String theory says that these fundamental particles are extremely small one dimensional objects known as strings. So strings are the smallest thing in the whole universe as everything, even the subatomic particles are made up of these one dimensional objects called strings. Graviton is a quantum mechanical particle that carries gravitational force. In string theory one of the many vibrational states of the string corresponds to the graviton.

String Theory Explained Video

What is String Theory

String theory deals with how these strings propagate through space and how do they interact with each other. According to the string theory all fundamental particles are actually tiny vibrating loops of string. Various properties of particles like mass and charge are determined by the vibrations of the one dimensional string like entities. According to researchers, the size of the string is about 10^-33 cm.

Why String Theory is Important?

Scientists hope that string theory will help in answering deepest questions related to fundamental physics. String theory has been applied to unravel mysteries of early Universe cosmology, black holes, nuclear physics and condensed matter physics. Quantum gravity is one of the deepest problems in modern physics. All the fundamental forces except gravity are described within the framework of quantum mechanics. As Albert Einstein described gravity using the general theory of relativity but the general theory of relativity is formulated within the framework of classical physics. According to Einstein's general theory of relativity, gravity is the distortion of space-time caused by the presence of matter. So a quantum theory of gravity was needed in order to reconcile general relativity with the principle of quantum mechanics. String theory can help us here. Actually string theory potentially provides a unified description of gravity and particle physics. It is a self contained mathematical model that describes all fundamental forces and forms of matter. So we can say that string theory is a candidate for a theory of everything. Now let’s get an idea about how small are the strings in string theory.

Size of Strings in String Theory

Actually a string is of the order of 10^-33. This number is so small that just by staring at this number you won’t get the idea. So let me make it simple for you with an analogy. Let’s assume an atom were magnified, to the size of the whole observable Universe, then a String would be the size of a tree!!! Now let me do one more comparison to make it more clear. This time I'll compare the size of an electron with the size of a string. So, if we increase the size of an electron equal to the size of the Earth, then a string would not be bigger than just a 3 storey building.

Strings in String Theory | The Smallest Thing in the Universe | String Theory

Strings, the Smallest thing in the universe ! Do you know, What is the smallest thing in this universe? According to string theory the smallest thing in the universe is the String.
Some of you will say, that Atom is the smallest particle and according to some, subatomic particles like electrons, protons and neutrons are the smallest particles, and some others that are from the science background may say that, particles like Quarks, Muon, Photon, Higgs boson, Graviton etc. are the smallest particles in the universe that can not be divided further. But that's not true.


What are Strings in String Theory

Actually according to recent studies, the smallest thing in this universe is unimaginably small. It is the 'strings' of string theory. It is so tiny that it doesn't seem to occupy any space.
But before Knowing how small a string is, it is important to know what is a string according to string theory.


What is String Theory

In Physics, string theory is a theoretical framework in which the point like particles of particle physics are replaced by one-dimensional objects called strings. According to the string theory all fundamental particles are actually tiny vibrating loops of string. Various properties of particles like mass and charge are determined by the vibrations of the one dimensional string like entities. The String theory describes how these strings propagate through space and interact with each other.


How small are Strings in String Theory 

According to researchers, the size of the string is about 10^-33 cm. This length is so small that your mind cannot understand this number without giving you an example and analogy.
So let's try to understand it. Let me first tell you that 10^-33 cm is actually millionth of a billionth of a billionth of a billionth of a centimeter. I know you are confused again. Ok let's try again, this time by giving you an interesting analogy.
To give you an Idea let's compare the size of a string with the size of an atom.
If an atom were magnified, to the size of the whole observable Universe, then a String would be the size of a tree!!!
Now let me do one more comparison to make it more clear. This time i will compare the size of an electron with the size of a string.
So, If we increase the size of an electron equal to the size of Earth, then a string would not be bigger than a 3 storey building.
After giving you 2 examples, I can hope you can imagine the unimaginably small size of the String.
So friends, Now you know, what is the smallest thing in the whole universe and how small it is.
