Theory of everything

Theory of everything is a predictive theory in physics that yet not discovered, is a unified theory that will be able to describe all of the phenomenon in physics.

Theory of everything is realised to discover to overcome the contradiction among the physics theories.

Theory of everything will be the ultimate theory in physics to describe al of the physics phenomenon.

It is also called the ultimate theory or master theory.  It is a single theory of theoretical framework of physics that can explain and can links with all other physics theory and theoretical aspects in universe

Two different theoretical aspects upon which all of the physics is rest on is quantum field theory and general theory of relativity. The difference in general theory of relativity from quantum field theory is that general theory of relativity is focusing on gravitation and understanding of universe in large scale and massive object such as stars and galaxies  and quantum field theory is focusing on three non gravitational force.

Three non gravitational force,  strong force, weak force and electromagnetic force combine and merge and leads to emergence of grand unification theorem.

Quantum field theory and general theory of relativity is incompatible with each other. Both two theories are not implement in same case.  QFT is for low scale and low mass but general theory of relativity is for high mass and high scale.

Gauge Symmetry

In mathematics,  Lagrangian system admits a special types of symmetry that is called Gauge symmetry. Not only in mathematics, but also in physics gauge symmetry have wide range of applications. In theoretical physics gauge field theory and depends of some parameter function.

Gauge symmetry of Lagrangian is defined as the differential operator on some vector bundle with the condition of its value taken in linear space.

Gauge symmetry is depends on vector bundle and its partial derivatives. Example of such types of dependencies in Yang-Mills theory, classical field theory and Gauge gravitation theory.

There happens some odd things in gauge symmetry
Being Lagrangian symmetry, gauge symmetry satisfies first Noethers theorem.


According to second Noether theorem, Gauge symmetry and Noether identities have a relationship of one to one correspondence. This one to one correspondence is satisfies by Euler-Lagrange operator.

Gauge symmetry characterize the degeneracy of Lagrangian system.


In terms of quantum field theory, there found another complexity.  There a generating functional fail may found invariant under gauge transformation. In this case gauge symmetry is replaced and BRST symmetry is introduces instead of it.

Grand unification theorem

Grand Unification Theory is simply called GUT.  It is a model in particle physics that is unified form of three gauge interaction. These three  gauge interaction is electromagnetic force, strong force and weak force.

The properties of Grand Unification Theorem is that it is characterised by a larger gauge symmetry with just only one coupling constant. Due to merging of three fundamental interaction out of four fundamental interaction in universe causes Grand Unification theorem.

The authenticity of Grand unification theorem is the reality of Grand unification epoch in early universe when the fundamental interaction of universe were not distinct.

The difference of GUT form theory of everything is in terms of gravity.  Gravitation is not merged in GUT with other three fundamental interaction.

Grand Unification Theorem is not generally acceptable. It is very complex.  The realisation of GUT model is comparing very complex with standard model. In Grand unification theorem there need additional field of interaction and additional dimension of space.  In GUT there have difficulty of reproducing observed Germain masses and mixing angle.

Baryon

We know about quarks. The combination of three quarks made a sub-atomic particles that is called baryon. Baryon is an element of hardon family. Just like baryon, messon is also a member of hardon family.

The word baryon comes from greek. Baryon means heavy. When it was named as baryon then it was higher mass than most of the existed elementary particles.

Baryon is special types of quark based elementary particles that participates in strong interaction, though another quark based particles lepton do not participate in strong interaction.
