The Elegant Universe : ( Part 3 of 3 ) .

Part - 3 of 3  ( Welcome to the 11 th Dimension ) . 

How to control space and time ?

All the things are made up of tiny strings .
When we bend space-time we can create wormholes .




                             Wormhole formed by tearing the fabric of space-time and connecting it . 

        " According to String theory Einstein was not always right . "

Rips in space-time fabric . ripping a hole in the space-time continuum



                                           Rips in space - time fabric . 
                            " Strings can protect the rips in the space-time fabric ."




What are the hidden dimensions ?
 There are tiny strings vibrating inside Quarks .

Different types of vibrations of strings gives different types of matter.

Its necessary to master vibrations of strings .

"   *** There were 5 types of strings theory ?   "

Edward witten :- A conference held in 1995 .
He gave new prospective of string theory .
Edward said its just " 5 different ways of looking the same theory " . 

Here comes the new " M-Theory " . 







Normally there are 10 dimensions .

1 time dimension  ( T )
3 spacial dimension . ( X , Y, Z )
6 other small-scale dimensions ( Microscopic )



                                                           3 spacial dimensions  (X , Y, Z ) . 






                                                            4 th dimension Time ( T )






                                      6 dimension Calabi Yau space structure  ( Microscopic ) . 
                                       



But according to M- Theory there are 11 - Dimensions .

When there are more dimensions there are more degrees of freedom .

When strings are stretched they form membrane (or) brane .

This was a 3-dimensional approach .
These had a lot of energy and thus had a large size ( size of the Universe )
High dimension of space.






Consider a dough of bread . 

                                 
                                                                        Dough of bread .




Slices of bread . 





Here one slice may form one UNIVERSE .


                                              Consider this as a UNIVERSE .



Consider these Parallel slices of bread as parallel UNIVERSES . ( Extra dimensions ) .


                                                          Parallel slices of bread . 
                                    

Considering these slices of bread these forms extra dimensions .

Newtons gravity " Apple " -> An important force of Nature . ( G ) .

Magnets has E.M ( Electro magnetic ) force .

E.M   >>>  G 

1 X 10 ^ 39   >>>  1   

E.M  is greater then Gravity by 1 followed by 39 zeros .

Why can't we feel strength of Gravity ?

                                                                 Snooker .
 
   While playing snooker the sound waves are produced that are like gravity waves .

Why Gravity was so different ?

Strings are tied to 3 - Dimensional membrane .





                                                Open and closed strings . 






                                                          Strings encircling Graviton .



Graviton appears in other dimensions and hence is weak in the present dimension .

Hence Gravity is very weak in present dimensions .

At the instant of Big - bang all physical laws breakdown .



Physical laws breakdown at the instant of big bang . 

It is sometimes suggested that Big-band did not happen at all by String - theory . 


                                                    Membrane Universes ( Parallel ) .


When these membrane collide then BIG-BANG occurs , because energy of collision should go somewhere .


                                                           Colliding membranes .


They collide many times and hence many times Big - bang occurred .

Can string theory solve Big - bang ?

Detecting the evidence of Strings . 






In FERMI-LAB , Atom smashers .



                                            Atoms collide to give Graviton .

FERMI - LAB :- Located in the border of France and Switzerland .


                                                           


                                                           FERMI - LAB 



CERN :- Atom smasher .

 It is 7 times stronger than FERMI - LAB .







                                       CERN : - LHC   ( large hadron collider ) 








*** Super - symmetry .



In particle physicssuper symmetry (SUSY) is a proposed extension of spacetime symmetry that relates two basic classes of elementary particles:bosons, which have an integer-valued spin, and fermions, which have a half-integer spin.[1] Each particle from one group is associated with a particle from the other, called its super partner, whose spin differs by a half-integer. In a theory with perfectly unbroken super symmetry,

Each pair of super partners shares the same mass and internal quantum numbers besides spin  . 

Since no super partners have been observed yet, super symmetry must be a spontaneously broken symmetry if it exists . 

If super symmetry is a true symmetry of nature, it would explain many mysterious features of particle physics and would help solve paradoxes such as the cosmological constant problem .

Do sparticles exists ?







FERMI   v/s   CERN .

Still we need 10 - 20 years for clear understanding of atom - smashers .

Is still string - theory right (or) wrong ?

Still how many years to wait ?

Everytime we looked closer to UNIVERSE we discovered new truth .

String theory , Extra - dimensions , sparticles . etc ........
