An exploration of the idea that all true technological intelligence is inherently artificial in a sense, including the human brain. This has major implications on the Fermi Paradox and may be one of the strongest solutions of why when we search the heavens, we do not see evidence of alien life.
Asteroid samples fetched by NASA hold not only the pristine building blocks for life but also the salty remains of an ancient water world, scientists reported Wednesday.
The findings provide the strongest evidence yet that asteroids may have planted the seeds of life on Earth and that these ingredients were mingling with water almost right from the start.
“That’s the kind of environment that could have been essential to the steps that lead from elements to life,” said the Smithsonian Institution’s Tim McCoy, one of the lead study authors.
Amid the swirling vastness of galaxies, each a cosmic city of stars and planets, the silence raises a compelling question: could the very nature of galaxies themselves hold the key to why intelligent life remains unseen?

Could tiny grains from asteroid Bennu unlock the secrets of life in our solar system?
Does life exist beyond Earth and have the building blocks of life existed in our solar system for billions of years? This is what a recent study published in Nature Astronomy hopes to address as a team of international researchers analyzed dust samples obtained from the asteroid Bennu, which is hypothesized to have broken off from a larger parent body, to ascertain if it contains the building blocks of life as we know it. This study has the potential to help scientists better understand the early conditions of the solar system, along with the formation and evolution of the planets and moons that comprise it, as well.
For the study, the researchers used a transmission electron microscope at Goethe University to analyze grains that were part of the 122 grams (0.27 pounds) of dust samples returned to Earth by NASA’s OSIRIS-REx mission in September 2024. The goal of the study was to ascertain what components comprise Bennu, which existed since the early days of the solar system more than 4 billion years ago.
In the end, the researchers identified greater amounts of nitrogen, carbon, and ammonia than were obtained from asteroid Ryugu by Japan’s Hayabusa2 spacecraft in 2020. Additionally, this study identified 14 of the 20 amino acids that comprise Earth-based biology, along with all five nucelobases that comprise DNA and RNA. These findings indicate that the building blocks of life potentially existed in the solar system billions of years ago and could comprise some of the planetary bodies of astrobiological interest today, including Saturn’s moon Enceladus and dwarf planet Ceres.
How long until alien life reaches us? If an extraterrestrial life form was travelling to the solar system, how long would it take for it to reach us?

Thirty years after the discovery of the first exoplanet, astronomers have detected more than 7,000 of them in our galaxy. But there are still billions more to be discovered. At the same time, exoplanetologists have begun to take an interest in their characteristics, with the aim of finding life elsewhere in the universe. This is the background to the discovery of super-Earth HD 20,794D by an international team including the University of Geneva (UNIGE) and the NCCR PlanetS.
The new planet lies in an eccentric orbit, so that it oscillates in and out of its star’s habitable zone. This discovery is the fruit of 20 years of observations using the best telescopes in the world. The results are published in the journal Astronomy & Astrophysics.
The OS axiom posits that reality operates like a computational construct. Think of it as an evolving cosmic master algorithm—a fractal code that is both our origin and our ultimate destiny. This axiom doesn’t diminish the beauty or mystery of existence; on the contrary, it elevates it. When we think of the universe as a computation, we realize that the laws of physics, the flow of time, and even the emergence of consciousness are not random accidents but inevitable outcomes of this higher-order system.
This concept naturally leads us to the Omega Singularity, a term I use to describe the ultimate point of universal complexity and consciousness. Inspired by Pierre Teilhard de Chardin’s Omega Point, this cosmological singularity is where all timelines of evolution, computation, and consciousness converge into a state of absolute unity—a state where the boundaries between the observer and the observed dissolve entirely. In The Omega Singularity, I elaborate on how this transcendent endpoint represents not just the culmination of physical reality but the quintessence of the “Universal Mind” capable of creating infinite simulations, much like we create virtual worlds today.
But let’s take a step back. How does this all relate to the OS axiom? If the universe is computational, it means that all processes—be they physical, biological, or cognitive—are governed by fundamental rules, much like a computer program. From the fractal geometry of snowflakes to the self-organizing principles of life and intelligence, we see the OS postulate at work everywhere. The question then becomes: Who or what wrote the code? Here, we enter the realm of metaphysics and theology, as explored in Theogenesis and The Syntellect Hypothesis. Could it be that we, as conscious agents, are co-authors of this universal script, operating within the nested layers of the Omega-God itself?

We often speculate that the reason we can’t hear aliens civilizations is because our SETI efforts (the Search for Extraterrestrial Intelligence) relies on radio and telescopes to weak to hear them. But how plausible is that? and what would it tell us about our own future?
The Zoo Hypothesis is a Fermi Paradox solution that assumes extraterrestrial civilizations can’t be detected by our SETI efforts because they keep our whole world in an Alien Zoo.
