A Proposal for a Neutrino Detection Array Spanning 200,000 Square Kilometers

Sometimes in astronomy the acronym for a project fits it particularly well. That would absolutely be the case for the Giant Radio Array for Neutrino Detection, who hopes to scale up to a size of 200,000 sq km in an effort to measure ultra-high-energy tau-neutrinos. Is it ambitious? Yes, but that doesn't really stop humanity …
