Witrynatons. But the perturbation theory has zero radius of convergence, and so doesn’t actually de ne a \theory". You need M-theory for that, but that’s not yet a \theory" either. As a possible UV completion of the standard model. But the \landscape prob-lem" makes it unclear whether String Theory will have any predictive power. WitrynaSo formulas for scattering amplitudes can in some way be considered as fundamental equations defining the theory. Very schematically, the equation to calculate the scattering amplitude A can be written down as.

WitrynaIn string theory such features include the 6 extra dimensions, the presence of excited string modes, and a particular scattering behavior at high enough energies. If you could test these features and not find them, it would pretty much falsify all string theory models. Of course this is not practical because the required energy scale is way ...
