Wind Blows from the Milky Way’s Black Hole: Evidence Emerges
What the discovery suggests For decades, scientists have watched supermassive black holes at the centers of galaxies both consume material and, on occasion, spew it back into space as powerful outflows. While some active galaxies proudly display dramatic jets, our Milky Way’s own Sagittarius A* has long appeared unusually quiet. The latest observations, however, hint…

Setting Bounds On SETI: A Hybrid Strategy Using BOAT GRB 221009A
Overview: the SETI data deluge The Search for Extraterrestrial Intelligence (SETI) faces a data scale problem. The universe is vast, and even if we could detect signals from other civilizations, deciding where to look, which frequencies to monitor, and when to listen is a monumental task. Against this backdrop, a new arXiv preprint by Naoki…

Setting Bounds On SETI: A Hybrid Spatial-Temporal Signaling Strategy
A Hybrid Spatial-Temporal Framework for SETI The Search for Extraterrestrial Intelligence (SETI) faces a data-scale problem: there are countless places to listen, countless frequencies to sweep, and timing windows that may pass undetected. Traditional anchors—like listening near a presumed natural beacon or picking a single historical event as a cue—have limitations. A new preprint from…

Setting Bounds On SETI: A Hybrid Strategy Linking Galactic Center and BOAT GRB
Introduction: The SETI data scale problem The Search for Extraterrestrial Intelligence (SETI) faces an enormous data scale challenge. With countless stars and a near-infinite range of frequencies and observation times, even a smart instrument can drown in possibilities. A new pre-print from Naoki Seto of Kyoto University proposes a practical way to narrow the search…
