Neil deGrasse Tyson and Edward Snowden recently discussed the idea that encryption mechanisms with advanced extraterrestrial species and humans could theoretically render communication as indistinguishable from cosmic background radiation. With only a short period of time in a species growth where open communication is broadcast to the stars (through the sluggish and primitive nature of radio broadcasts), this could prevent us (or other species) from making contact with one another.

With the Drake Equation stating a high probability of communicative extraterrestrial civilizations and the contrasting Fermi Paradox citing lacking evidence of such, it begs the question of whether outlying reasons have an impact. In my opinion, the Drake Equation rings true in the sense that hundreds of billions of stars exist in our galaxy alone (many with their own diverse planetary bodies), setting the stage for extraterrestrial life to disavow itself as insatiable ramblings. Unlike that which is eminent in the Fermi Paradox, I believe, in this case, a conclusion based off of inductive reasoning seems to hold more water than an evidence-only approach.

Keeping in mind the discussion in The Guardian article, a flaw of the Fermi Paradox’s evidence-based perspective should become apparent: secure, encrypted communication (cloaked by design) would render the existence of extraterrestrial intelligence invisible to the prying ear. If intentional, there could be many reasons for withholding this whereabouts of a species location. An abstract theory from science fiction may itself hold a degree of truth. An example of which, is the video game series ‘Mass Effect,’ where an advanced, sentient machine-race cleanse the galaxy of advanced life every 40,000 years. The reasoning for doing so is to “bring order to chaos” and for reasons “unfathomable.” Be it for an abstract reason such as this or simply for secure communication, the encryption of the resultant transmission’s presence wouldn’t register as noticeable to any observers. As nearly all signs of outside life would be mute, it then lays in the other senses that hold the most promise of enlightenment.

Previous studies of the galactic habitable zone have been concerned with identifying those regions of the Galaxy that may favor the emergence of complex life. A planet is deemed habitable if it meets a set of assumed criteria for supporting the emergence of such complex life. In this work, we extend the assessment of habitability to consider the potential for life to further evolve to the point of intelligence—termed the propensity for the emergence of intelligent life, φI.

As astronomers get closer to finding potential signatures of life on faraway planets, a new mathematical description shows how to understand life’s spread — and to determine if it’s jumping from star to star. “Life could spread from host star to host star in a pattern similar to the outbreak of an epidemic,” study co-author Avi Loeb of the Harvard-Smithsonian Center for Astrophysics (CfA) said in a statement.

Long time ago I was wondering why not to use drones ( (named for that concrete application Extreme Access Flyers) to explore the space, to reach new planets, asteroids … it would be exciting … rovers are limited in action, so what if we make it airborne? Once in space, why not to send a drone or a swarm of them from the main spaceship to explore a new planet? They could interact, share capabilities, morph, etc.

While the economy looks more or less promising for civil and military, there is still a long path to walk …

“Teal Group’s 2015 market study estimates that UAV production will soar from current worldwide UAV production of $4 billion annually to $14 billion, totaling $93 billion in the next ten years. Military UAV research spending would add another $30 billion over the decade.”

It’s generally assumed that we will eventually find signs of life in the galaxy. But rarely do we consider searching for advanced civilizations that have destroyed themselves. Here’s how we could do it—and what the search for dead aliens could tell us about our own future.

Typically, astrobiologists and SETI enthusiasts are in the business of searching for signs of active extraterrestrial civilizations. Proposed signatures that could be detected by astronomical instruments on Earth include radio and optical signals, megascale engineering objects (such as Dyson Spheres) radiating in the far infrared, artificial illumination, and abnormal levels of atmospheric carbon dioxide suggestive of a post-industrial age civilization.

But a new study by a research team from Cornell University’s Carl Sagan Institute suggests we should also look for signs of alien civilizations that have destroyed themselves. It would be a grim task, but the ability to detect extinct civilizations would not only tell us something about the prospect of intelligent life in the galaxy, it might also tell us something about our own fate as well.

How does science fiction become science fact? Often the link between art and science can be hard to pin down. It can be unclear if science fiction is actually influencing science or merely observing it, giving the public sneak peaks into the implications of scientist’s work.

But some work of science fiction create direct links to the future. As a young man in Russia, Konstantin Tsiolkovsky read a translation of Jules Verne’s ‘From the Earth to the Moon.” And although Verne’s plan to get to the moon wouldn’t have worked, the novel had just enough science mixed in with its romance to make the central idea seem plausible. Tsiolkovsky became obsessed with the idea of spaceflight, and his life’s work created the foundations of modern rocketry.

One hundred years after Verne wrote his novel, a group of individuals who had been inspired by Verne’s fantasy as children launched a voyage to the moon.
