Currently, virtually all SETI (search for extraterrestrial intelligence) experiments scan the skies looking for radio or light signals. However, over the years, some researchers have suggested that another, potentially better way to find evidence of alien life is to not look for broadcasts from afar, but instead to hunt for what are essentially messages in a bottle — a SETA (search for extraterrestrial artifacts) approach.
For example, in 2004, researchers suggested that broadcasting a signal across the cosmos is expensive and inefficient. Instead, the scientists calculated that inscribing messages onto a hunk of matter and launching it at potential extraterrestrial pen pals would require about a trillionth as much energy.
Another concern with conventional SETI is that extraterrestrial civilizations may be long dead by the time astronomers do actually detect signals from them. In contrast, extraterrestrial artifacts could provide a way for us to directly learn about alien civilizations, especially if these artifacts are equipped with artificial intelligence...
In the new study, Benford developed a version of the Drake equation for artifacts. The new formula specifically focused on what he calls "lurkers" — hidden and likely robotic extraterrestrial probes. Although the civilizations that deployed these lurkers may well be dead, the lurkers themselves could still be active enough to communicate with us.

His brothers James and Gregory are heavily into science fiction. Believe Greg authored a few books in which a character is involved in discovery of the remnants of a machine intelligence facility upon Earth’s moon.
And every lock that ain’t locked when no one’s around.
Aliens carefully brought the moon into the earth’s orbit. It is really made of metal and mostly hollow inside, except for the work and sleeping quarters the aliens use. On the dark side of the moon there is a space ship docking bay. The moon is really a giant death star and if we humans get out of line the aliens will blow up the earth.
The ship’s name is Dahak. It’s sentient and replaced the real moon around 50 to 60,000 years ago.
