The Fermi Paradox
The well-known Fermi Paradox is a simple question with no clear answer: “where are all the aliens?” Given the immense size of our galaxy (not to mention the size of the entire universe), it seems likely that life would have bloomed on other planets, and that on at least some planets, this life would be […] Continue reading
the fermi paradox
Sir Arthur C. Clarke, a British science fiction author, said that “two possibilities exist: either we are alone in the universe or we are not. Both are equally terrifying”. And he was exactly right! The more that we learn about and explore the universe, the more we learn about the possibility of life out there, […] Continue reading

Blog 7 – The Dark Forest Solution to Fermi’s Paradox
Fermi’s paradox is that based on the number of stars in our galaxy and estimates on the likelihood of intelligent, space-faring civilizations to develop in a star system, we should expect to see some signs of alien life in our galaxy. Some possible solutions to the paradox are that Life is more rare than we […] Continue reading

The Fermi Paradox is the conflict between the lack of evidence of extraterrestrial life and high estimates for its existence. The main explanation people have come up with for this paradox is that intelligent life is rare. Using this explanation, it makes sense why there would be many places with rudimentary life, but without intelligent […] Continue reading

Where is Everyone?
The Fermi Paradox was developed in 1950 by the Italian-American physicist Enrico Fermi. The paradox itself refers to the notion that if there is an extremely high possibility of life outside of Earth, then why have humans not discovered evidence of other intelligent life forms. This could be for a multitude of different reasons such […] Continue reading

Where are all the Aliens? Natural and Self-Inflicted Explanations for the Fermi Paradox
Broadly speaking, our views on the probability of extraterrestrial life have gotten more optimistic over time due to a long series of discoveries that have increased our estimates for the size of the universe, the frequency of planets, the frequency of liquid water on worlds, and the ability for life to thrive in extreme conditions.Continue reading “Where are all the Aliens?

The Fermi Paradox & Possible Implications
Are we alone? This sentence, likely thought by many humans around the world and throughout history in hundreds of languages, brings forth a profound question. Also known as the Fermi Paradox, the search for intelligent extraterrestrial life has captured many minds. If life is so plentiful here on Earth, and there are so many habitable […] Continue reading
Extraterrestrial Existence
Shouldn’t Earth have been visited by extraterrestrials already? Enrico Fermi, a physicist from Italy, asked the same question in 1950 and sparked a wonderful conversation in the field of astronomy and astrobiology. In 1975, Michael Hart published “An Explanation for the Absence of Extraterrestrials on Earth,” noting that the lack of intelligent life from the … Continue reading Extraterrestrial Existence → Continue reading

The Fermi Paradox
The age-old question of whether life exists on other planets in the Solar System is one that may not be solved for centuries. Frank Drake and Sara Seager spent years developing their respective equations (shown below) that can be used to predict the probability of aliens existence, but the concept of life outside of EarthContinue reading “The Fermi Paradox” Continue reading
The Fermi Paradox
The Drake Equation honestly surprised me by how plausible the existence of aliens could be somewhere in the universe. However, that could also be used as damning evidence in the claim of extraterrestrial beings. If intelligent intergalactic life is as probable as astronomers believe, how have we not found any yet. It is a simpleContinue reading “The Fermi Paradox” Continue reading
