The Existence of Extra Dimension (Superstring Theory)

I have posted about this theory in my Friendster Blog 2 years back in a simpler version after I heard a speech by a famous Prof. 'Liang Yan Cheng'.
Now, this will be the Advanced Version of it.
This is a very Complex theory which is still developing and it is categorized in the branch of Theoretical Physics.
Theoretical physics employs mathematical models and abstractions of physics in an attempt to explain experimental data taken of the natural world.
The goal is to rationalize, explain and predict physical phenomena.

I'll put them up based on my very little understanding of it.
The Purpose for this post is to explain about Ghost.

Ok, Here we Start!

We are living in the Space consisting of 3+1 Dimension.
The 3 Dimensions are
Length(Left and Right)
Width (Forward and Backward), and
Height (Upward and Downward).
And the last Dimension is Time.
And hence the word 'Spacetime' purposed by Albert Einstein in his Theory of General Relativity.

However, is the space that we are living today consist merely of the 3+1 Dimension that we are able to detect by using our 5 senses only?
Is there an existence of Extra Dimension that we are unable to detect by using our body 5 senses?
The answer is YES. (Think how the word Sixth Sense came about)
The 'Space' that we are living now does not consist of 'us' only but it also consists of other 'living things' which we are unable to 'sense' them.
Those 'living things' are called as 'Ghost' in layman's term.

And the Extra Dimension can be explained using the Superstring Theory.
We must know about certain concept and terms 1st before we can know(I don't use the word understand here cause it is rather complex, but we can know about it) about the Superstring Theory.

1. What is String?
A String is one of the main objects of study in String Theory.
A String is an object with a one-dimensional spatial extent, unlike an elementary particle which is zero-dimensional, or point-like.

There are 2 Types of String: Closed and Open String.
A Closed String is a string that has no end-points, and therefore is topologically equivalent to a circle.
An Open String has two end-points and is topologically equivalent to a line interval

Not All String Theories contain Open Strings, but Every theory must contain Closed Strings, as interactions between Open Strings can always result in Closed Strings.

Strings can also possess an Orientation, which can be thought of as an internal "arrow" which distinguishes the string from one with the opposite orientation.
An Unoriented string is one with no such arrow on it.

2.What is String Theory?
String theory is a still-developing approach to theoretical physics, whose original building blocks are one-dimensional extended objects called strings.
String theory attempts to reconcile quantum mechanics with general relativity in order to describe a quantum theory of gravity.

3.What is Superstring Theory?
Superstring theory is an attempt to explain all of the particles and fundamental forces of nature in one theory by modelling them as vibrations of tiny supersymmetric strings.
It is considered one of the most promising candidate theories of quantum gravity.
Superstring theory is a shorthand for supersymmetric string theory.

The Extra Dimension
Our physical space is observed to have only three large dimensions and—taken together with time as the fourth dimension—a physical theory must take this into account.
However, nothing prevents a theory from including more than 4 dimensions.
In the case of string theory, consistency(which means there's no contradiction) requires spacetime to have 10, 11 or 26 dimensions.
The conflict between observation and theory is resolved by making the unobserved dimensions compactified.

Our minds have difficulty visualizing higher dimensions because we can only move in three spatial dimensions.
One way of dealing with this limitation is not to try to visualize higher dimensions at all, but just to think of them as extra numbers in the equations that describe the way the world works.
This opens the question of whether these 'extra numbers' can be investigated directly in any experiment (which must show different results in 1, 2, or 2+1 dimensions to a human scientist). This, in turn, raises the question of whether models that rely on such abstract modelling (and potentially impossibly huge experimental apparatus) can be considered scientific. Six-dimensional Calabi-Yau shapes can account for the additional dimensions required by superstring theory.
The theory states that every point in space (or whatever we had previously considered a point) is in fact a very small manifold where each extra dimension has a size on the order of the Planck length.

4. So , What I actually want to say?
Actually Ghost are just living things that live in different dimension.
They are more powerful than us, I mean they can do things that seems extraordinary to us, but at the same time those extraordinary things are actually very easy task for them.
Furthermore, they can see us but we cant see them.
Let me use an Analogy on this, from an Ant's point of view.

Ant, is an animal which live in a '2+1' dimension world.
They know Length and Width but they don't know Height.
In addition, they have fewer sense organ compare to Human Beings.
One of the most important different is We can see Ants but Ants can't never see Us.

Let's say when the ant is moving forward, you put your hand in front of it and block it's way for a while and remove it after that to let it pass.
If the ant can think like us, they will be wondering...
''Why suddenly there is a 'mountain' in front blocking me and the next second the mountain is removed?''
The stupid ant might think that 'he' is being disturbed by a 'Ghost'.
It is so easy for us to block and unblock the ant's way, but for that particular ant, it will wonder why is this happening and scared.

And now, let us think that We are the Ant and those living things(Ghost) that live in the other dimension are Human and read back the analogy above.
How do you feel? haha~

Anyway, don't worry.
There is no such thing as Ghost in this world(or rather in the space that we are living).
Those living things that live in the other dimension are called as Spirit.
Like human, there are Good and Bad(evil) Spirit.

The Good spirits will always protect Human from being attack/disturb by the Bad spirits, unless for certain reasons only those bad spirits are able to attack you such as you give in to it, you ask help from it, you constantly thinking of it and scare yourself, or you have some 'weak points' being exposed to them and they will attack you through those 'weak points'.

Actually most of the time those bad spirits won't exposed themselves to human but they are always around and lure one to do bad things, to take the wrong path.

As for Christian, we do not scare of Evil Spirit because we know we have a God who is greater and more powerful than them. Jesus lives within our hearts and we are being protected.
When Jesus stepped ashore, he was met by a demon-possessed man from the town. For a long time this man had not worn clothes or lived in a house, but had lived in the tombs. When he saw Jesus, he cried out and fell at his feet, shouting at the top of his voice, "What do you want with me, Jesus, Son of the Most High God? I beg you, don't torture me!" For Jesus had commanded the evil spirit to come out of the man. Many times it had seized him, and though he was chained hand and foot and kept under guard, he had broken his chains and had been driven by the demon into solitary places.

Jesus asked him, "What is your name?"

"Legion," he replied, because many demons had gone into him. And they begged him repeatedly not to order them to go into the Abyss.

A large herd of pigs was feeding there on the hillside. The demons begged Jesus to let them go into them, and he gave them permission. When the demons came out of the man, they went into the pigs, and the herd rushed down the steep bank into the lake and was drowned. (Luke 8: 27-33)

This is just one of the story from the bible that shows Jesus authority on Evil Spirit.
There are many other in the Book of Gospel.
Note that what the 'Legion' said to Jesus when 'They' 1st saw Him, He claimed that Jesus is the son of the Most High God.

P/S: All the explanation concerning the Superstring theory are from Wikipedia. I have read through and tidied up everything to make them as simple as possible to be 'digest'.
P/P/S: Watch this video about Superstring Theory and you will understand the theory a lot more. Yea, I said A LOT more and I mean it!
It is a very interesting video which explains the theory with simple words and animation.
