Supported by the recent detection of a TXS 0506+056 blazar neutrino with an energy in the TeV–PeV range detected by the IceCube experiment, a probe of a new physics scale related to high-energy cosmic neutrinos is provided. At Standard Model energies, the effect of the underlying physics is first investigated. Then, the recorded IceCube170922A data is used to approach the scale of such a new physics which lies above the Grand Unified Theory scale eV.
