The Fermi Paradox is a complicated contradiction that considers the probability that other life in the Universe exists, and asks why we have never encountered it. Essentially, some calculations were made to suggest with a high probability that there are many worlds in our universe and even solar system that are habitable, and that the … Continue reading Where are they?

Believe it or not, there are organisms on Earth that can survive unimaginable conditions! These beings are called extremophiles, and they’re nothing short of amazing. One example is the tardigrade, which can live in the most extreme heat, cold, dehydration and radiation. The simple fact that these organisms exist give us reason to believe that … Continue reading Resilient Life on Earth Increases Possibility of Extraterrestrial Life → Continue reading → Continue reading
Is liquid water necessary for life to form? If judging strictly from the only life we know, of course. However, humanity’s exploration of the universe has just begun, and we can’t say for sure what lies beyond Earth. Other worlds within our solar system have organic compounds that life could possibly evolve from. In particular, … Continue reading Methane-Based Life → Continue reading → Continue reading
The Fermi paradox is named after the famous scientist Enrico Fermi. In this paradox, Fermi acknowledges the apparent contradiction between the amount of extraterrestrial life that we have detected (none) and the high probability that extraterrestrial life exists. For these “high probabilities”, Fermi was drawing on lines of reasoning similar to that presented in the…
The Fermi Paradox is the apparent contradiction between the lack of evidence for extra-solar civilizations and the fact that there is a high probability that many Earth-like planets exist that are older than ours and that it would conceivably be possible to explore the galaxy in a couple million years. Simply stated, where are the … Continue reading Blog 6: The Fermi Paradox → Continue reading → Continue reading
Astrobiology is becoming an increasingly discussed topic as new exoplanets are being found and we discover more about the worlds of our own solar system. Of course, for there to be life on other planets, it first needs to come into existence on its own through abiogenesis, or the creation of life through non-biological sources. … Continue reading Hydrothermal Vents: The Origin of Life? → Continue reading → Continue reading
The Search for Extraterrestrial Intelligence (SETI) has been ongoing for about 60 years now, and it’s time to reconsider if it’s worth the millions of dollars and hours it burns every year. To start off, I want to make the case that SETI isn’t real science. It’s a faith-based effort that isn’t falsifiable. An article … Continue reading SETI isn’t Science: Why the Search for Aliens is a Waste of Resources → Continue reading → Continue reading
We hear about aliens all the time, whether in books or movies or tv shows, and this leads us to ponder our own existence. Are we alone, or is there other life out there? This is a question that has plagued mankind since begun exploring interstellar space, and started looking for life in our own … Continue reading The Drake Equation Continue reading → Continue reading
Simply stated, the Fermi Paradox asks the question, “Where Are All The Aliens?” The life-projecting equations we’ve discussed in class, such as the Drake and Seager Equations, all seem to suggest that thousands, millions, or billions of other forms of life should be out there in the universe. But if that’s the case, why haven’t … Continue reading The Fermi Paradox and The Great Filter → Continue reading → Continue reading
As we’ve seen over the past few generations, our ability to harness technology to accomplish things never before seen or done has only increased exponentially. As a race, we’ve been able to photograph a black hole, we’ve been able to send probes to places in space that were thought to be unreachable, and we’ve just … Continue reading Are We Alone? → Continue reading → Continue reading
