This paper asks: is it possible that there are cosmic ray signal SO BIG that they cover the Earth? We found a mechanism, the GZ effect, which would shatter cosmic rays in half before they reach the Earth, creating two impact sites that are correlated in time. Current cosmic ray observatories are awesome, but not big enough to see Earth-sized effects like this. So we wondered if one could see them using a cosmic-ray telescope made out of smartphones, based on this idea: <LINK> Turns out you can! It's a bit tricky, and you need something more common than vanilla GZ effect, but there's a laundry list of exotic theories that would generate such effects. Right now, we're just not looking for it.",https://arxiv.org/abs/2102.03466,"We explore the sensitivity offered by a global network of cosmic ray detectors to a novel, unobserved phenomena: widely separated simultaneous extended air showers. Existing localized observatories work independently to observe individual showers, offering insight into the source and nature of ultra-high energy cosmic rays. However no current observatory is large enough to provide sensitivity to anticipated processes such as the GZ effect or potential new physics that generate simultaneous air showers separated by hundreds to thousands of kilometers. A global network of consumer electronics (the CRAYFIS experiment), may provide a novel opportunity for observation of such phenomena. Two user scenarios are explored. In the first, with maximal user adoption, we find that statistically significant discoveries of spatially-separated but coincident showers are possible within a couple years. In the second, more practical adoption model with $10^6$ active devices, we find a worldwide CRAYFIS to be sensitive to novel ""burst"" phenomena where many simultaneous EASs occur at once.
