    From the link:
    :biggrin:

    S-matrix theory from the sixties also had these three basic ingredients...

    Falsifying Models of New Physics via WW Scattering
    Jacques Distler, Benjamin Grinstein, Rafael A. Porto and Ira Z. Rothstein
    We show that the coefficients of operators in the electroweak chiral Lagrangian can be bounded if the underlying theory obeys the usual assumptions of Lorentz invariance, analyticity, unitarity and crossing to arbitrarily short distances. Violations of these bounds can be explained by either the existence of new physics below the naive cut-off of the the effective theory, or by the breakdown of one of these assumptions in the short distance theory. As a corollary, if no light resonances are found, then a measured violation of the bound would falsify generic models of string theory.

    It was told about a former Distler's work in PF...

    Technological improvements to capture more detailed cosmic maps should help narrow down the possibilities and may allow scientists to crack the code of the cosmic energy map - and inch closer to identifying the single geometry that fits our universe.

    The implications of such a possibility are profound, says Tye. "If this shape can be measured, it would also tell us that string theory is correct."



    LOL. It would?
