Hey, Where is Everybody?
When we studied the Drake Equation in class, it was interesting to note that using the maximum possible values for each variable in the equation, there could be as many as 21,000,000 detectable civilizations out there right now waiting to be discovered? If there are so, so many civilizations out there sending communication into space … Continue reading Hey, Where is Everybody? → Continue reading
Fermi Paradox
Do you believe in aliens? With over 4,000 planets outside of our solar system and likely many many more, it seems almost crazy not to. Using the Drake Equation, astronomers estimate the probability of alien life outside of our solar system. Depending on the scientist’s opinions and research, this number can vary greatly but oftenContinue reading “Fermi Paradox” Continue reading

The Fermi Paradox
The Fermi Paradox is the paradox that while there are probably other intelligent life forms in the Milky Way, none have have made any communication with Earth. Since Earth is a younger planet of the Milky Way, if intelligent civilizations existed they would likely be much older, meaning they would have the technology to communicate […] Continue reading
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
