Vertebrate population dropped about 60 percent.

Very alarming news of extinction causing in world animals. A large scale of animals are getting extinction due to certain cause. Most of the cause are men maid. The worlds environment is getting unfavorable to survive.

According to WWF, the plannets vertibrates dropped about 60 percent since 1970.
Seabirds are foumd plastic in their stomach.


Freshwater species is declined about 83 percent since 1970.


The major cause of declining of animals from our plannet is water warming, increasing of atmosphere temperature. Rappid industrialisation and unprotective method of discharging of industrial waste.

A destabilized climate can not give people  happy and healthy life.

Electroweak theory

To describe the electromagnetic force and weak force together electroweak theory is emerged. The basic difference of weak force from electromagnetic force is that electromagnetic force acts in large scale where weak force is active in small scale. The distance like a range of atomic Nucleus weak force is found. But electromagnetic force attraction is found in large scale.

Sunlight is an electromagnetic force. It comes from sun from a large distance.

Fundamental interaction

There exists four fundamental interaction in universe. Four fundamental interaction in universe is as follow,


weak force



Due to strong force formed. It acts between quarks that bind proton and neutron.

Weak force:

 Interaction between electric field and magnetic field creates electromagnetic force.

 Interaction of any objects in universe is gravitation.

How to control gastric problem

Most of the people may found with gastric problem. It is very difficult to identify clearly that what is the root cause of gastric problem.

It is a digestive system disease. That may cause by various factors. HCl is a gastric acid for digestion. Chemically it is Hydrocloric acid.

What we eat, there need digestion. HCl plays an important role in digestion. When HCl releases in digestive system in a uncontrolled rate then gastric problem is seen.

Medication can control gastric problem. But there need life style change. Frequent moving, excersise can control gastric problem more effectively than medication.

Regular scheduled mealing is another factor that significantly control gastric problem.

Fuzzy nebulous object

Nebula is a latin word that means cloud or fog. It includes dust, fog, cloud or other astronomical object. Nebulae is any astronomical objects including galaxy beyond the milky way.

Andromeda galaxy is reffered as andromeda nebulae and spiral galaxy is reffered as spiral nebulae.

Nebulae are very big in size. Some may be hundred of light year diameter. From earth any nebulae may look very big, but not brighter. The brighter nebulae near earth is orion nebulae.

Nebulae produces by stars. Some of the nebulae is found to form by gas that is in interstelar medium.

Supernovae plays an important role in producing nebulae. supernovae explosion of stars throw some massive cloudy objects that forms nebulae.

Most of the nebulae found are diffusion nebulae. Diffussion nebulae have no exact boundary. Emission nebulae and reflection nebulae is such types of example of diffusion nebulae.

When lower mass stars undergo into stellar evolution, the final stage of steller evolution of lower mass stars forms planetary nebulae.

Lorentz transformation

In physics Lorentz transformation is a transformation of co-ordinates between two co-ordinate frames that moves at constant velocity relatively each other.

Dutch scientist Hendrik Lorentz develops such types of co-ordinate transformation. For that reason such types of co-ordinate transformation is named Lorentz transformation with his name.

In co-ordinate transformation frame of reference is highly considerable. Frame of reference is divided into two groups. Inertial group and non-inertial group. Inertial frame of reference focusses on the  relative motion with constant velocity.

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.
