The civilizations would have to be super advanced in order to generate the 100 MHz signal that they are scanning for. Huge amounts of energy would have to be channeled into transmission of such signals. Would we ever expend such an effort to tell someone in another galaxy that we exist? 100 MHz is in the middle of the FM radio band, but in our expanding universe what would have been the frequency transmitted by any one of the 2,800 galaxies scanned in the survey? https://www.sciencedaily.com/releases/2024/08/240826131354.htm Ron Okimoto
