They hope to find a beacon announcing the presence of an intelligent species out among the stars, but they also are looking for any signal that might indicate intelligence even though it is not intended as an announcement.

In cyber-security, a stealthy attempt at reconnaissance often involves slowing down a scan until the time frame goes below the parameters in the intrusion detection signatures and the scan effectively disappears from the radar of the defenders. SETI radio astronomers monitor space for tell-tale radio signals that might demonstrate […]

Fermi Paradox

If our Solar System and planet Earth are typical of the universe, then considering how many galaxies and how many stars there are, the place should be teeming with intelligent life. (see the link to the Drake Equation below that discusses this) The Fermi Paradox is that in spite of this logical reasoning that there […]

The equation includes a series of values that are estimated by common sense or logic or any other means available. Once the values are filled in, the equation […]
