What is string theory? That is a mysterious epic!!!

To explain General Theory of Relativity and Quantum Field Theory by String Theory !!!

We know everything in the world through two theories. The first is the General Theory of Relativity and the second is the Quantum Field Theory.

These two theories are right in their own purpose. Just understand that if the size of an object is large then the general theory of relativity will work there and if the size of an object is very small then the quantum theory will work there.

String Theory

Why two different theories for knowing all the facts of this universe? Can't we come up with a theory that will help us understand all the events in the universe !!! This is the origin of string theory in physics. What is special about this theory is that it speaks of quantum gravity. Even Multiple Universe, Multiple Dimensions, and the previous answer to the Big Bang.

If there is a theory that would prove our quantum gravity, we would get a unified theory that would make it easier for us to explain the general theory of relativity and quantum field theory. For all the theories offered in the past, string theory claims to be the only one that can explain quantum gravity.

Suppose you have an object.  Now if we think on a microscope level what it is made of !! But we find that these are made of atoms. Now if we go inside the atoms, we will see that there are tiny electrons in it, which revolve around the nucleus. And if we go inside the nucleus, we get newtons and protons. Now if we go inside first, we will get quarks. With which our proton particles are made.

Here we end up thinking about modern physics. And we think quarks are the smallest part of an object. This is why it cannot be broken. But string theory says that there is an energy inside the quark which is always vibrating. Which makes it look like a vibrating spring. It can be round or swollen or straight.

When you see a guitar vibrate in a different pattern, different sounds come out. When these energy strings, located within the quarks, vibrate in different patterns, they form different particles and take the form of different objects.

If we had a microscope that would allow us to see the smallest object on this earth, we would see that we have the energy to look around like a spring that is vibrating at different frequencies.

Because they vibrate at different frequencies, they produce different particles. This is why the universe is so diverse. Every object and every particle in this universe is made up of objects that look like strings.
