Where is everybody?
The Fermi Paradox addresses the famous question: are we alone? Statistically, it’s extremely unlikely that Earth hosts the only life in the universe. Most of the universe is (by current knowledge) unreachable to humans. But let’s look at our own galaxy. Many estimates say there should be at least a hundred thousand civilizations in theContinue reading “Where is everybody?” Continue reading
Let’s Talk about Aliens
I don’t know about you, but thinking of aliens brings up images of UFOs and bright green skin, bulbous heads and an echo of “Take me to your leader.” However, this representation of extraterrestrial life is simply something made up by… Continue reading

So Where Are the Aliens?
Our galaxy should be teeming with civilizations, but where are they? If we imagine that we would be able to survive long enough to become interstellar travelers, and that we begin to colonize habitable planets around nearby star systems, we would have dozens of outposts around nearby stars within a few centuries. We would beContinue reading “So Where Are the Aliens?” Continue reading
Where is everybody?
Despite evidence that suggests that there should be extraterrestrial civilizations, we have not yet detected any signs of these civilizations. This issue is called the “Fermi Paradox,” after Enrico Fermi—a Nobel Prize-winning physicist. Compared to the lifespan of the universe, our sun is relatively young at 4.6 billion years old, so there are older stars […] Continue reading
Fermi Paradox
What is the Fermi Paradox? In the most basic sense, the Fermi Paradox addresses the contradiction for the high likely hood of extraterrestrial intelligent life and the absence of any communication with our planet. Physicist Enrico Fermi asks the extremely thought-provoking question, “Where is everybody?”. While there are a number of interesting theories and possibilities … Continue reading Fermi Paradox → Continue reading
Life in Our Solar System
One of the biggest questions that philosophers and scientists alike ask: Are we alone in the universe? Is it possible that there’s sentient life outside of our small blue planet? The Fermi Paradox asks us this question. The universe is so big. Using even the most conservative estimations of exoplanets in the habitable zone, calculations […] Continue reading

Fermi Paradox
Named after Enrico Fermi, the Fermi paradox essentially asks the question: Where are the aliens? If you think about it, there are tons of stars in the galaxy. Billions that are similar to our sun! Many of these stars are older than our earth and most likely have some earth-like planets around them. Therefore, there […]

Blog #7: The Great Filter Theory
If we think for a moment about the size of our universe and how many Earth like planets orbiting a star much like our Sun, it doesn’t take long to begin to wonder, where is everybody else? This is called the Fermi Paradox. Some estimate that there should be about 10 quadrillion (10 million billion) […]

How Astronomical Are Our Chances of Finding Extraterrestrial Life?
I’ve always thought that we weren’t alone in the world–and my Astronomy class has really helped to confirm my thoughts. After studying the Drake Equation, it seems almost certain that intelligent life and life that could eventually communicate with us must exist. After all, the Earth is only 4.6 billion years old–a baby compared to […]
