Possible societal effects of a SETI success
By: Perry McCarney
WE ARE NOT ALONE! This is the least information we would derive from a SETI (Search for ExtraTerrestrial Intelligence) success, yet the most profound. Likely to rock our society to its very core and possibly fracture it into opposed camps that would violently clash...
An explanation of the Fermi paradox
By: Perry McCarney
It IS rocket science! But fortunately we do not need to be conversant with the technical specifications of spacecraft propulsion systems to understand the rationale behind Enrico Fermi's (1901-1954) question "Don't you ever wonder where everybody is?" The question is generally stated as...
By: Elton Gahr
For years SETI has been looking for messages from outer space, searching the sky for signs that we are not alone in the universe, but while we have been listening rarely have we said anything ourselves. The Arecibo Broadcast is the most powerful of our...
When could humans first set foot on Mars?
By: D. Vogt
A manned mission to Mars is quickly emerging as the most important near-term goal for the future of manned space programs. Just as was the case prior to the missions to the Moon in the late 1960s, there remains considerable uncertainty over how to resolve...
Space technology future: Non-polluting rockets for space exploration
By: Anthony Megna
The future of space exploration looks bright indeed with some of the ingenious non-polluting rockets on the drawing board! Leading the way is the solar-sailor, a spaceship that uses the power of the sun the explore the solar system. Just as the ocean explorers of...
Why the Search for Extraterrestrial Intelligence (SETI) may not be a good idea
By: D. Vogt
There are essentially two arguments for why the Search for Extraterrestrial Intelligence (SETI) may not be a good idea: it is a waste of funds, and it may end up attracting unwanted attention from hostile or exploitative alien civilizations. On balance, as can be quickly...

What was the Arecibo Broadcast?
By: Perry McCarney
Messages to outer-space have become somewhat contentious lately. Are we seeking technologically superior, benevolent extra-terrestrial species or setting ourselves up as victims to more scientifically and militarily capable predators? While the Arecibo broadcast was the first electromagnetic METI (message to extraterrestrial intelligences), only preceded by...
By: Imonikhe Ahimie
SETI, or the Search for Extra Terrestrial Intelligence, is a collective designation for a series of experiments designed to ascertain whether or not there is intelligent, communicative life in outer space. The search has been carried out, mostly, by trying to detect radio transmissions...
The speed of light explained
By: Irrira Rikki
MUST ACCOMODATE Why must a text book be the only explanation to the speed of light, when even the scientists who wrote down their 'theories only' are taken to be gospel truth? Are there no new minds around in this today's Space Age, who...
