Part - 2 of 3 ( Strings the Thing )
String theory is a lot stranger .
Here tiny bits of strings are vibrating energy .
Strings the thing .
Quantum cafe : Here we can order one thing and get another .
Two theories always describe the Universe .
1) General relativity :- All the big things in Universe ( G . R ) .
2) Quantum mechanics :- All the small things in Universe ( Q . M ) .
How to unite both Quantum mechanics and General relativity ?
General relativity (G.R) : - Space-time fabric .
Quantum Mechanics (Q.M) :- Space-time fabric twisted ( bumping ) .
General relativity (G.R) :- Gravity is the force .
Quantum mechanics (Q.M) :- Strong nuclear force (S.N.F) present in the nucleus .
Electromagnetic force (E.M) present in the electricity .
Weak nuclear force (W.N.F) present in Radioactivity .
In the heart of every bit (or) matter there is vibrating energy called strings which determines properties of matter .
There are no experiment to confirm the existence of " String theory " .
In 1968 :- Gabriele Veneziano discovered strong nuclear force ( S.N.F ) .
Around 200 years old there was an equation called Leonhard Euler equation which gave birth to String theory .
Leonard Susskind discovered strings .
In olden days new particles where discovered by smashing atoms .
Messenger particles :- Acts between two different energies (or) forces .
When we move backwards on the cosmic-scale we get.
E.M + S.N.F --- Super force .
Quantum mechanics :- How all the matter behaves .
In 1972 John Henry Schwarz gave mass less particles which had anomalies .
" Strings described gravity at Quantum world ."
Anomalies of quantum world solved in 1984 when they mathematically obtained L.H.S and R.H.S of an equation correctly , where n = 496 .
Cosmic symphony . ( Extra dimension ) .
In 1919 they found extra dimensions .
When we shrink to a smallest size we find other dimensions .
Extra dimensions -> Microscopic small .
Microscopic 6 - dimensional Calabi-Yau space structure .
String theory .
There are 20 constants of nature .
If we change a bit of anything then everything gets altered .
Constants of Universe .
In 1985 it was discovered there are 5 types of strings .
5 - Types of string theory .
Now the question arrived that which one to follow .
Which is correct ?
