STRING THEORY

STRING THEORY

The Theory which has superiority, the theory which is completely unique and different, the theory which has magic in it is STRING THEORY. The possibilities are impossible but STRING THEORY made everything possible.

This theory is of five different types:

Type I

Type IIA

Type IIB

E8*E8 heterotic

SO(32) heterotic

This theory was thought it’s wrong and ended but Edward Witten solved the theory like a puzzle he joined all the five different string theories and made it Unified M-Theory.

What is a STRING?

Matter is composed of atoms and which atoms has protons ,electrons and neutrons and in turn these particles are made up quarks and these quarks are made of STRINGS, this is called String level coming from what we see an object or a matter to its smallest particle. This string vibrates at the size of Planck’s length 10^-35m at particular resonant frequencies.

Observe the below figure you may understand what the level is

M-THEORY

The unification of five string theories (three super strings and two heterotic strings) the combination is M-Theory. This theory has 11 dimensions but looks like 10 dimensions in some points in its space of parameters. And also It describes a object called membrane.

This theory mainly has 3 factors which depends on them

1.Gravity

2.Nonabelian Guage symmetry

3.Supersymmetry

Gravity:

All the five string theories state about the gravity and also the quantum mechanics,standard quantum field theory makes gravity impossible.

Nonabelian guage symmetry:

In this theory the guage fields also carry the charges

This is the second prediction Nonabelian gauge symmetry measurably small corrections proportional to α’

Super symmetry:

It states that every fundamental particle must have a shadow force carrier particle and every force carrier must have a matter particle .The relation between the shadow force carrier particle and matter particle is called super symmetry.

TIME TRAVEL

Time Travel, some people just think it just a science fiction ,time travel wow!!! traveling into the future past sounds very interesting ,yes there is a physics behind this as Einstein's two theories-General theory of relativity and special theory of relativity,these include black holes ,worm hole,cosmic holes ,extra-dimensions and many more.He said that worm holes are like a tube or a shortcut connecting to space and time,space and time are curved as shown in figures,it's a shortcut.

There are many laws supporting time travel,M-THEORY(String theory) particle physics-the large hadron collider(CERN) are trying to find out the extra dimensions by colliding the protons nearly 99.99% speed of light.

One Physicist Dr.Ronald mallet ,as Einstein said that space and time are curved ,Dr. Mallet is trying to bend the space time using the ring laser he started few years ago may be he might successfully complete it by facing the paradoxes,like grand father paradox and other but still there is a way out says Dr Mallet .

This Time Travel theory which is interlinked to all parts of physics like Astronomy,cosmology ,Quantum mechanics, Astrophysics,Particle physics, Technology and others.

Let us wait few more years for the changes in physics
