Neutrinos offer a particularly promising view of the extreme Universe. Since neutrinos are not attenuated by the intervening CMB and other radiation fields, they are messengers from the very distant and very young universe. Since neutrinos are not degraded or absorbed by the source material at production, they carry information about central engine dynamics. Since neutrinos are not deflected by cosmic magnetic fields, they should point to their sources. This will allow astronomy to be performed. The neutrino cross-section at extreme-energy (≳ 1020 eV) may also offer a window to new particle physics above thresholds inaccessible to terrestrial accelerators. Measurement of an anomalously large neutrino cross-section would indicate new physics (e.g. low string-scale, extra dimensions, precocious unification), while a smaller than expected cross-section would reveal an aspect of QCD evolution. Here I focus on the significance of the neutrino cross-section at extreme-energy (EE), and how it may be determined; and on hints in the EE cosmic ray data which may already implicate ≳ 1020 eV neutrinos.
