String Theory - The Theory Of Everything

The String Theory – most of the people who are enthusiastic to know about science or are currently pursuing science as their major field of education must have come up with this term. This theory is currently the most controversial topic in the field of science, which is also arguably the most important theory in this history of science. Let us understand a little more about this topic.

Now, before we start to talk about the string theory, we must all know about 2 types of physics. The first type of physics is called the classical physics or Newtonian physics. In classical physics we consider particles which are mostly visible to the human eyes. Which means that those items are larger than the wavelength of the visible light. The reasons we are able to see things is because of a phenomena called the reflection of light. When light hits the surface of a substance, then that substance absorbs a specific amount of energy from the light. And the leftover energy is reflected to our eyes. The colour of an item is specific to us only because of the leftover energy which is reflected to our eyes. Now the classical physics has been dominant for many centuries, and it is still applicable in most of our day to day life. However as we have progresses as humans, we have also tried to unravel many mysteries of the science. This leads us to the second type of physics, which is called quantum physics.

When we apply light to a large item then the energy can be easily absorbed. As the particle gets smaller and smaller, its stability gets gradually affected as well. We are now at a point where we are working with particles which are even smaller than the wavelength of light. Which means that light will not be reflected from these particles. If we need to see smaller particles, then we will have to increase the frequency of the light wave. But if we increase the frequency, then we must also energize the light wave. How suppose a high energy light wave hits a very small particle which is unstable. What will happen? The small particle will immediately be dislocated. This is the reason that classical physics does not work with quantum particle, and we had to create a new classification of physics.

In spite of all this, humans have always found a way to learn things. Due to various type of experiments, we were able to discover a little bit about the quantum particles. Some of the quantum particles know to humans are boson, lepton, quark, proton, neutrino, electron, gluon, etc. All of this is but a very small fraction of the type of quantum particles out there. We have now discovered black hole but classical physics does not work in these mega structures. We have known about big bang but do not know how it exactly happed. We know about time dilation but do not know how to achieve is effectively. All these problems are based on quantum physics but is our current rate of progress it will take us a huge amount of money and time to understand these phenomenon, which is not a feasible way. Hence scientists had been tirelessly working on a new ways to understand these phenomenon, which leads us to a theory called THE STRING THEORY.

The string theory tells us that just like how every king of music note can be played using the string of a violin, every king of particle in this universe can be described as a vibration of strings. This is the most complex theory known in science and I do not expect people to understand it just but an essay, but to simplify it, each length of the string is made using multitude of particles and affecting one part of the string alters the properties of the particles adjacent to it.

However the reason it is so complex is that string theory does not consider 2 or 3 or 4 dimensions, but 10 DIMENSIONS. This is currently impossible to speculate using a human’s view point. This is why this theory cannot be practically proven in its original form. Scientists have been trying for years to convert this theory into a definable 3 dimensional model but have been unsuccessful. However we can be sure that, if string theory is proven practically, all the mysteries of the universe will be complete unravelled us. We might be able to solve the mystery of the origin of the universe and probably time travel and time warp.
