Neutrino telescopes, such as IceCube Neutrino Observatory, detect astrophysical very-high-energy neutrinos from distant astrophysical objects. Here, we report the first preliminary result using astrophysical neutrino flavour information to search anomalous space-time effects allowed by new physics theories. Neutrinos are elementary particles of Nature, and they are composed of three types, or flavours; electron, muon, and tau neutrinos. Neutrino flavours are a new way to study, or "taste" the universe, because new space-time structure can drive non-standard flavour mixings of neutrinos which can modify the flavour data from the standard cases. We did not find any evidences of an anomalous flavour mixing from IceCube astrophysical neutrino flavour data. Although the current statistics and detector sensitivity allows us to search rather special new physics effects, we demonstrate the sensitivity of this new approach goes far beyond any known technologies, and we reach for the first time the necessary precision to look for new physics within the Planck scale expectation.
