Summary:
- The article discusses the potential of using high-energy astronomy to search for signs of extraterrestrial intelligence (SETI) in the universe.
- It explains how the detection of high-energy particles or radiation could provide clues about the presence of advanced civilizations that might be harnessing the energy of their host stars or other cosmic phenomena.
- The article highlights the advantages of this approach, such as the ability to detect signals over much larger distances compared to traditional SETI methods, and the possibility of identifying technological signatures that could be missed by other search techniques.
