“Twinkling little stars” that’s what comes to most of our minds when we think of universe. And that is what came to our ancestors mind when they were fascinating about universe. Unlike most of ourselves they started exploring it and laid the foundation for where we stand now. We know a lot more about universe, or at least we think so. Well, to tell you the truth dear reader we can only see 4% of our universe; 96% is the portion we cannot see. Now how can we expect to know about universe when we cannot see most part of it? Our explorers or scientists worked for decades to find the solution. And they finally reached the conclusion that the answer is not in the deep space but in the realm of very small subatomic particle. They proposed a theory…show more content…
Think of a guitar string that has been tuned by stretching the string under tension across the guitar. Depending on how the string is plucked and how much tension is in the string, different musical notes will be created by the string. Similarly, every particle is made up of tiny strings, like musical notes the vibration of string will produce excitation in particles. How can that be? Well, we would ordinarily picture an electron, for instance, as a point with no internal structure. A point cannot do anything but move. But, if string theory is correct, then under an extremely powerful 'microscope' we would realize that the electron is not really a point, but a tiny loop of string. A string can do something aside from moving it can oscillate in different ways. If it oscillates a certain way, then from a distance, unable to tell it is really a string, we see an electron. But if it oscillates some other way, well, then we call it a photon, or a quark, or a ... you get the idea. These strings are very tiny; if an atom was magnified to the size of the solar system, a string would just be the size of a tree. String theory could be the theory of everything. It perfectly explains the nature of the cosmos and unifies the general theory of relativity and quantum
