Fermi Paradox: 71 years later, SETI may have solved the cosmic mystery

Posted by in categories: alien life, existential risks

“Where is everybody?”


The Fermi Paradox has perplexed scientists for years. We examine the possibility that we haven’t heard from any aliens is because no one is transmitting.

Could Simulation Theory Explain Why “Space is Hard”?

Posted by in categories: alien life, existential risks

What if none of this is real? What if everything we see, hear, touch, taste, smell, and perceive is part of a gigantic simulation designed to keep us contained? And what if the beings who built this simulation are part of a highly advanced alien species that created the simulation so they could study us and keep us under control.

This is the essence of the “Zoo Hypothesis,” which is a proposed resolution to the Fermi Paradox. It is also sometimes referred to as the “Planetarium Hypothesis” as a way of clarifying that the intention of the big simulation is not to protect but to control. Moreover, the zookeepers in this scenario have designed the simulation so that humanity won’t suspect they are living in a cage.

Rogue Planets Could be Habitable

Posted by in category: alien life

There might be billions, even trillions, of rogue planets in the Milky Way. Could they support life? How can we find out?


The search for potentially habitable planets is focused on exoplanets—planets orbiting other stars—for good reason. The only planet we know of with life is Earth and sunlight fuels life here. But some estimates say there are many more rogue planets roaming through space, not bound to or warmed by any star.

How neutron star collisions flooded Earth with gold and other precious metals

Posted by in category: alien life

It killed some alternate ideas about gravity, too!


The universe is pretty good at smashing things together. And when neutron stars do it, the collisions release a flood of elements necessary for life.

NASA’s Got A New, Big Telescope. It Could Find Hints Of Life On Far-Flung Planets

Posted by in category: alien life

The James Webb Space Telescope will let scientists study small, rocky planets around distant stars in more detail than ever before. After decades of work, it could head into orbit later this year.

How does terraforming work in the Alien universe?

Posted by in categories: alien life, engineering, environmental

Back to Aliens, we find “Building Better Worlds” as the main slogan of the nefarious Weyland-Yutani Corporation. Apparently, terraforming (and presumably mining) celestial bodies is a large part of their galactic business. When acid hits the fan and the xenomorphs take over Hadley’s Hope, their operations on LV-426 have been active for decades. But is that enough time for Acheron (formally labelled as LV-426) to develop a breathable atmosphere?

The film itself doesn’t have many answers when it comes to terraforming, but the procedure appears to revolve around reutilizing the existing atmosphere – breaking down pre-existing elements, transforming, and redistributing them – instead of starting from scratch, which would indeed take centuries. Basically, mankind can’t turn any planet or planetoid into an Earth-like environment in the Alien universe; most components need to be present already, same goes for the atmospheric conditions. This fixes the centuries-long problem that comes up in other works of fiction, or at least makes the storytelling more realistic.

Complementary material detailing the Alien universe’s history and technology claim the first “Automated Atmosphere Processor” became a reality in 2,029 with a first terraforming process happening on Gliese 667 Cc during the 2030s and ending around 2040. The Weyland Corp Terraforming Division was created in 2,072 effectively starting a new age of space exploration. As stated before, native atmospheres are transformed thanks to the company’s “Atmosphere Processing Plants” and other techniques, such as algae bloom tanks that consume excess carbon dioxide and generate oxygen. It all depends on the properties of planets which have been previously scouted, inspected, and approved for viable terraformation.

Mars Was Always Destined to Die

Posted by in categories: alien life, chemistry

Mars is the solar system’s near-miss world. Earth may have gotten everything right when it came to sustaining life—atmosphere, water, proximity to the sun. Mercury, Venus and the outer planets, with their extreme temperatures and inhospitable chemistry, may have gotten everything wrong. Mars, on the other hand, came so close, yet fell short.

Thanks to data from rovers and other spacecraft, we know that the Red Planet once fairly sloshed with water—with dry deltas, riverbeds, and sea basins stamped into its surface. But 4 billion years ago, the Martian core cooled, shutting down the dynamo that sustained its magnetic field. That left the planet vulnerable to the solar wind, which clawed away the atmosphere, and allowed the Martian water to sputter into space. Before long—in geological terms—the planet was a desert.

At least that’s long been the thinking. But a new paper published Sept. 20 in the Proceedings of the National Academy of Sciences suggests otherwise. According to the new research, Mars was doomed from the start. Its small size—about half the diameter of Earth and less than one-ninth the mass—simply never produced the gravitational muscle to allow the planet to hold onto either its air or its water. With or without a magnetic field, Mars was destined to die.
