A Short Story of `String` Theory ;
;{After Brian Greene `s ` Fabric of the Universe `:ISBN 0-375-41288-3}
`String theory accounts for messenger particle exactly as it accounts for matter particle......If string theory is correct, the usual concept of space and time , the frame work within which all of our daily experiences take place simply don`t apply on scales finer than Planck`s scale (scale of string).....there would be no such thing as distance shorter than Planck`s length or duration shorter than Planck`s time.........here is a theory that can quell the hostility between Quantum mechanics and General relativity.
Even if the Theory is proved right no body will ever see a `string`.( it is like recording this page from a distance of 100 light -years. Electrons have 3 times the electric charge of the down- quark. Particle-properties are determined by strings vibrational pattern..... The mass of a particle in string theory is nothing but energy of its vibrating string.`
