The Elegant Universe: Part 1

This the part 1 of the bestselling book by "BRIAN GREENE" , explaining string theory and many more.. String theory may well be THE THEORY OF EVERYTHING fulfilling ALBERT EINSTEIN's dream for an unified theory..

STAY TUNED FOR THE REST OF THE PARTS....2 more to go...

STRING THEORY

The Basics of String Theory


At its core, string theory uses a model of one-dimensional strings in place of the particles of quantum physics. These strings, the size of thePlanck length (i.e. 10-35 m) vibrate at specific resonant frequencies. (NOTE: Some recent versions of string theory have predicted that the strings could have a longer length, up to nearly a millimeter in size, which would mean they're in the realm that experiments could detect them.) The formulas that result from string theory predict more than four dimensions (10 or 11 in the most common variants, though on version requires 26 dimensions), but the extra dimensions are "curled up" within the Planck length.

In addition to the strings, string theory contains another type of fundamental object called a brane, which can have many more  dimensions(a mind blogging 11 dimensions).In some "braneworld scenarios," our universe is actually "stuck" inside of a 3-dimensional brane (called a 3-brane).

String theory was initially developed in the 1970s in an attempt to explain some inconsistencies with the energy behavior of hadrons and other fundamental particles of physics.

As with much of quantum physics, the mathematics that applies to string theory cannot be uniquely solved. Physicists must apply perturbation theory to obtain a series of approximated solutions. Such solutions, of course, include assumptions which may or may not be true.

The driving hope behind this work is that it will result in a "theory of everything," including a solution to the problem of quantum gravity, to reconcile quantum physics with general relativity, thus reconciling the fundamental forces of physics.

Variants of String Theory


Bosonic String Theory: The first string theory, which focused only on bosons.

Superstring Theory: This variant of string theory (short for "supersymmetric string theory") incorporates fermions and supersymmetry. There are five independent superstring theories:

  • Type 1

  • Type IIA

  • Type IIB

  • Type HO

  • Type HE


M-Theory: A superstring theory, proposed in 1995, which attempts to consolidate the Type I, Type IIA, Type IIB, Type HO, and Type HE models as variants of the same fundamental physical model.

Research in String Theory


At present, string theory has not successfully made any prediction which is not also explained through an alternative theory. It is neither specifically proven nor falsified, though it has mathematical features which give it great appeal to many physicists.

A number of proposed experiments might have the possibility of displaying "string effects." The energy required for many such experiments is not currently obtainable, although some are in the realm of possibility in the near future, such as possible observations from black holes.

Only time will tell if string theory will be able to take a dominant place in science, beyond inspiring the hearts and minds of many physicists.

Upcoming Post

Want to know about "String Theory" ? I hope you do..Its one of the latest theory put forward by scientists.

Its a theory to know how this whole mechanism of this universe started,what we are made,why each objects have their own specific characteristics...and many more

So stay tuned to know more on "String Theory",which may be that one theory which can explain everything of this universe...
Sorry everyone I had been for so so so long time...I had some family issues to deal with..Now I am back and will go on posting more scientific facts for you..And thank you guys for sharing,commenting and following my blog even after my long absence...

NEW POST COMING SOON :-) :-)
