Laser scanners have been installed in two US states to search for extraterrestrial civilizations. These are LaserSETI lasers, which are the development of the Hawaiian SETI Institute, which implements a program to search for intelligent beings outside the Earth using lasers.
The lasers are installed in Hawaii, at the summit of the Haleakala volcano, and in California, at the Robert Ferguson Observatory in Sonoma. As American experts suggest, humanity cannot detect extraterrestrial civilizations because it does not have the necessary tools. LaserSETI aims to remedy this situation.
They will look for powerful laser pulses over the Pacific Ocean. Perhaps extraterrestrial civilizations are also looking for answers in space using a laser.
