Some critics of string theory say that it is a failure as a theory of everything. Notable critics include Peter Woit, Lee Smolin, Philip Warren Anderson, Sheldon Glashow, Lawrence Krauss, and Carlo Rovelli. Some common criticisms include:

  1. Very high energies needed to test quantum gravity.
  2. Lack of uniqueness of predictions due to the large number of solutions.
  3. Lack of background independence.

Famous quotes containing the word criticisms:

    The sway of alcohol over mankind is unquestionably due to its power to stimulate the mystical faculties of human nature, usually crushed to earth by the cold facts and dry criticisms of the sober hour. Sobriety diminishes, discriminates, and says no; drunkenness expands, unites, and says yes.
    William James (1842–1910)

    I have no concern with any economic criticisms of the communist system; I cannot enquire into whether the abolition of private property is expedient or advantageous. But I am able to recognize that the psychological premises on which the system is based are an untenable illusion. In abolishing private property we deprive the human love of aggression of one of its instruments ... but we have in no way altered the differences in power and influence which are misused by aggressiveness.
    Sigmund Freud (1856–1939)
