Implications of Directed Energy for SETI<\/h3>\n

 <\/p>\n

The implications of recent advances in directed energy\u00a0on\u00a0searches for extraterrestrial intelligence (since we have given up on finding\u00a0any here on Earth) are profound. We will explore the basic signal and noise properties of systems (basically a link margin calculation) and be able to show that it is already possible for us to both send and receive directed energy signals across the entire horizon (visible universe). This allow us to go vastly beyond the normal discourse of looking locally for sources of signals and search at extra galactic distances\u00a0for extremely narrow bandwidth signals that may be present from civilizations as advanced or more so than ourselves. This has profound implications for SETI given the likely number of planets that are now predicted\u00a0from the recent Kepler and other surveys, assuming that advanced civilizations even need to be on planets and that they have any desire to communicate with\u00a0others in regions of the electromagnetic spectrum we are able to access.

Trillion Planet Survey (TPS) <\/strong><\/span><\/h3>\n\n\n\n\n
We propose a search for continuous wave (CW) laser beacons from an intelligent civilization in the Andromeda galaxy. Using only a 0.8 meter telescope, a standard photometric system, and an image processing pipeline, we expect to be able to detect any CW laser signal directed at us from an extraterrestrial civilization in M31, as long as the civilization is operating at a wavelength we can “see”, had appropriate power and has left the beacon on long enough for us to detect it here on Earth. The search target is M31 due to its high stellar density relative to our own Milky Way galaxy. Andromeda is home to at least one trillion stars, and thus at least one trillion planets. This is an unprecedented number of targets relative to other past SETI searches. For this reason we call this project the Trillion Planet Survey.<\/i> -Stewart, Zhang, Lubin, & Taylor, COSPAR-2018 <\/a><\/td>\n\"\"

“If a class 4 civilization in Andromeda wanted to target the Milky Way and used our \u201cintelligent targeting\u201d scheme to maximize detection by intelligent life on planets, such as ourselves (i.e., target the stars in the Milky Way), then a simple Earth-based 3 year survey with a 1 meter telescope would detect a single class 4 civilization anywhere in Andromeda with near unity probability.”<\/i> – ‘The Search for Directed Intelligence’, REACH – Reviews in Human Space Exploration – Vol 1, 20-45, March 2016<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
