Galactic Communications Using a Gravitational Lens

Gravitational lensing is the process of a large mass bending light from a distant source. Einstein predicted this and astronomers can now detect it. By placing an optical collector or a radio antenna at a distance of 550 AUs or greater from our Sun, it can be used as a lens to focus detail from […]

The Length of a Civilization

The Drake Equation attempts to estimate how many intelligent civilizations may have developed over time in a given area of space. One of the most important factors in the equation is the length (L) of time that a civilization exists. This is wide open to speculation and it is tempting to assume that an advanced […]

Galactic ET-Net

Advanced civilizations will not be using the same technology that we use and just as ants might find it difficult to understand the internet, we struggle when trying to define advanced technology. Modulated waves of electromagnetic energy are not the only way to communicate. In the Standard Model of physics, the force carriers are divided […]

Imagine a Pea in a Swimming Pool

The standard size for an Olympic swimming pool is 50 meters long and 25 meters wide. Imagine a square pool half that size; 25 meters by 25 meters and around 9 feet deep. Throw into that pool a pea. The average pea is about 1/8 inch in diameter. The pool represents our galaxy, the Milky […]

Old Intelligence is Already Here

The article referenced below ponders the question of whether our technology is too primitive to detect advanced ET life. Yes, our technology is too primitive to detect technology that is advanced far enough beyond ours to avoid detection. The electromagnetic “profile” of life on Earth has been spreading out into space for about 100 years […]

Search for Old Intelligence

Our Search for ExtraTerrestrial Intelligence (SETI) programs scan the cosmos for tell-tale electromagnetic traces of other civilizations. 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. […]

Singularity Horizon

The “Singularity” describes a future event in human history where intelligence and ability are being replicated and growing so fast that a hyperbolic curve is created where there is one general growth rate before the singularity and a completely different growth rate after the event. The turning point, where the growth rate changes dramatically, can […]

ET Slow Scan

ET phone home. . . slowly. 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 […]

Golden Data

Voyager1 is currently the most distant human made object from the Earth, somewhere beyond 10 billion miles from the Sun. When we launched Voyager1 in 1977, a “golden record” was included with it, in the hopes that it would be able to communicate something about life on Earth to any intelligent beings that found it. […]

Drake Equation

The “Drake Equation” was composed by Frank Drake in 1960 as a means to predict the chances that there is intelligent life somewhere else in the universe. 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 […]
