what is string theory ?
string theory is theoretical and it is just like a mathematical tool other than classical physics like a cosmology .
string theory suggest that smallest thing in not point particle instead of that it is a string which are one dimensional extended object .
as in above fig the whole black part is universe and it is subdivided into small thread or string which is in blue color . small string connect together and make a anything around us .
These string propagate through space and interact with each other , such string have charge and mass. they possess a vibration by which it communicate with each other .
such vibrational state of the string include ;-
1. Gravition 2. Quantam mechanical particle 3. Gravitational force
1. Gravition;- it is hypothetical or imaginative theory they are expected to be massless it is belived
that something like gravitation and spin around space.
2. quantam mechnical particle;- In last article i have stated about quanta which according to plank's it is electromagnetic energy takes the form of tiny discrete packets called quanta.
3. Gravitational force ;- by which all things with mass are brought towards one another .
basically we may conclude with above discussion string theory is a theory of quantam gravity .
string theory is mathematics for the things like .
- a- black hole
- b- cosmology
- c- nuclear physics
- d- condensed matter physics
major challenge of this theory is that it is based on probability means;-
- it doesn't have satisfying answer for all the condition.
- it also describe many possibility of universe which is complicated and confusing.
but key features which is introduced by the string theory is ;-
- give possibility of parallel universe
which suggests that there could be other universes besides our own meaens
the person who is on this existing earth same copy of him on another earth.
just like we see our face in mirror . which is called multiverse (consist of many earths
around the space).
simply a man is doctor in earth1 may be same physical appearance on another earth but have different ability like he may be carpenter.
2 .Holographic principle;-
which states how information in a space can relate to information on the surface of that space.
