Fermi national labortory did a experiment and they found an unexplained phenomenon which made the scientist guess thepossibility of another kind of neutrino which could prove the string theory is right.

Many scientist hold the opinion that string theory was the only way to handle the conflicts between quantum mechanics and gravitation,which was Einstein’s last dream.

However things are not always goes as plain sailing.
The truth was that string theory could’t be test in laboratory.So that some scientist pointed out that it was only existed in fantasy.At the same time ,we could’t prove that it was wrong.
From where we stand,substance are consist of little dot,but string theory’s principle is line.

String theory was shaped in 1968 by Gabriele Veneziano,(伽布利耶· 威尼采亚诺)a Italian’s physicist.He merely wanted to find a function to describe the strong interaction between the nucleus.Fortunately ,he found the Euler's Function in a math book which is two hundred years ago.This function was the model of string theory. But the contiual development is Leonard Susskind’s(李奥纳 特· 苏士侃) discovery.
