Implications of Directed Energy for SETI

Under construction

The implications of recent advances in directed energy on searches for extraterrestrial intelligence (since we have given up on finding any 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 for 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 from 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 others in regions of the electromagnetic spectrum we are able to access.

Some of this is discussed in:
