"THE STRING THEORY"

Vibration produces everything

It is exist due to the physicists.
Brain Greene



It starts from the curious people.
German mathematician Theodor Franz Eduard Kaluza suggested very bold idea
He proposed our universe might not have only three dimensions but more than three dimensions. There might be some additional dimension but for some reason we don't yet see. When someone made a bold idea people won't believe in that & nothing to do with the world around us.
This particular idea however although whether we don't know right or wrong, but in the future Experiment may tell us right or wrong. This idea made major effect on physics from last century.
I like tell you about that extra dimensions let's go to the 1907 when Einstein discovered the Theory of relatively and try to understand in terms of gravity.
But many people says that Newton has already provided the theory on gravity and that explain the motion of planets, motion of everything around us. But Einstein knows that Newton had left something behind.But Newton knows that it's theory is correct but can't explain each and everything . Just like how does the sun attracted earth how?.
Here comes Einstein tell us how gravity works, Einstein tells us that space is flat as no matter present in there,if matter present in the environment such as the sun causes the fabric of space to work, and that communicate with the force of gravity.

According to these ideas moon is orbiting around the earth,in valley and in contour.
By the virtue of there present,so this the new idea how gravity actually works .

This idea was tested in 1919 through astronomical observation it really works and describes a data and this gained Einstein. Prominent around the world. This what Theodor Franz Eduard Kaluza ( German mathematician) was thinking that he like Einstein searching For unified Theory .
That one theory might be able to describe nature of all forces by one set of ideas , one set of principle,one master equation. Eduard Kaluza was thinking that Einstein been able to understand the gravity in terms of curves in space, infact space & time more precise. May I can play the same game with other known force, which was that time known as the electro magnetic force in terms of curves. So he proposed that there are more dimensions if I need to describe more forces. So he imagined that there are 4 dimensions not 3 .
So when he driveved the equation for four dimensions instead of 3 dimensions he found one more extra equation. So he found the equation that scientist used to describe EM force . So he was very happy that he found unified theory. He took his Theory very seriously. So question arises from his Theory that if there is extra dimension why we can't see them, & does this theory work in detail in practicality. First question was answered in 1926 by mathematician he suggested that dimensions might come in two verities there might be be easy to see dimensions there might be very small dimensions we can't see, it is present around us but we can't. See . If you go inside you will find amazing things that which explains that dimensions exist .
So this is the explanation that how the additional dimension exist .
Let's go to 2nd question does this theory work when you applied in the world around us. Einstein and many scientist work on try to find this frame work applied to physics​ of the universe. But they won't find the unified theory that explains everything. So here comes the string theory which can explain everything might clear our doubt.the theory which try to understand the basic fundamental individual uncuttable Constituents making up everything in this world around us.

If go inside the Apple you will find molecules then atoms then subatomic particles. Electrons orbiting around the nucleus, with nuetrons and protons even they have smaller particles inside of them known as quarks conventional idea stop there . Here the new idea of string theory

if go inside you will find a vibrating strings and these produces different patterns they don't produce different musical notes rather they produce different particles making up the world around us, vibrating in different frequencies produce the different particles, and different particles are responsible for everything around us, so you will find different particles . gravitons , quarks, electrons are all built up by one place. So if you see the vibrating string it's vibrating but Changes it's dimensions it is difficult to calculate the dimensions so string theory defines that yes extra dimensions exist .

Vibration determines everything.

One of the goals of Physics is to find a single theory that unites all of the four forces of nature. These are; electromagnetism, gravity, and the strong and weak nuclear forces. The first two are familiar. Electromagnetism is the force that holds a fridge magnet to a refrigerator while gravity is trying to pull it off towards the earth.
The strong nuclear force is responsible for holding the central part of atoms (their nuclei) together, while the weak nuclear force is involved in the decay of these nuclei.
In the attempt to tie all the four forces together a lot of interesting ideas and new theories have been proposed. One of the most promising of these new theories is string theory. In attempting to unite gravity with the three other forces, string theory requires us to change the way we view the universe.
According to the theory all particles are actually tiny vibrating strings and each type of vibration corresponds to a different particle. The different particles are like the different notes that can be played by bowing a violin string. However, the strings of string theory almost certainly would not look like violin strings.
String theory also requires us to accept the existence of extra dimensions in the universe. We are familiar with the four usual dimensions: up-down, forwards-backwards, left-right and time, but string theory requires seven more dimensions!

A universe of eleven dimensions seems strange to us but many physicists think these extra dimensions are possible and are looking for ways to detect them.
The attempt to unify the 4 forces of nature is one of the most exciting areas of physics and I hope to be around if this is successful, whether it is string theory or some other candidate that is successful. On the other hand there is the possibility that no single, theory exists that can describe all the forces of nature in a neat and tidy way as we would like.
Whatever the outcome, scientists from all over the world will continue working together to discover what could be the ultimate theory of everything.
String theory can make us understand everything and next part about multiverse.

To be continued...
