SETI

SETI is an acronym for the Search for Extraterrestrial Intelligence. It is an effort to detect evidence of technological civilizations that may exist elsewhere in the universe, particularly in our Galaxy. There are potentially billions of locations outside our Solar System that may host life. With our current technology, we have some ability to discover evidence of cosmic habitation, and, in the specific case of our SETI experiments, to find beings that are at a technological level at least as advanced as our own.
