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

Astrobiology – Indicators of Life on Other Worlds
Astrobiology studies the past, present, and future of life in the universe. One facet of this interdisciplinary field is considering the possibility of life on other planets or worlds. Scientists utilize research in biology, chemistry, astronomy, and cosmology to help determine if life could exist elsewhere in the universe, and if so, how we can […] 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

Alien civilizations. How many are there?
Throughout my life, I have always been curious of what lies beyond our sky and more importantly who lies there? After discussing the Drake Equation in class and also the probabilities and alignments necessary for there to be life, I am going to address this topic. According to the Guardian, scientists say that the amount […] Continue reading
Extremophiles (Post 7)
Extremophiles are types of organisms that can survive in abnormal or extreme conditions. The picture above is a popular tourist destination in Yellowstone National Park known as “Grand Prismatic Spring.” The spring is extremely hot at 160 degrees Fahrenheit but it is famous for its vibrant colors. These colors are actually caused by a type […] 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 Egg
A man named Andy Weir, created an idea of life and the universe called, The Egg. The story starts out with a man dying in a car crash and coming face to face with what seems to be God. Immediately this person begins asking about their family and the life they left behind along with […] Continue reading
The Fermi Paradox
The Fermi Paradox attempts to describe why we have not made contact/found any intelligent life although the conservative estimate for how many intelligent civilizations there are throughout the universe is ten million billion. This theory is completely based on speculative math using the data we know about our universe. The paradox also describes Types of […] Continue reading
Answer to the Fermi Paradox: They Just Don’t Need Us
The Fermi paradox states that due to the relatively high chance of intelligent life existing somewhere else in the universe, they should have visited us by now, except they have not yet. So why? There are currently some explanations ranging from intelligent life just not existing to them not deeming us worthy of participating in […] Continue reading

Where Are the Aliens?
Based on various calculations and estimations made by scientists all over the world, there is a very high probability that aliens (i.e. life elsewhere in the universe) exist. However, we have never encountered any tangible or irrefutable evidence of aliens. This contradiction is called the Fermi Paradox. One possible explanation for this paradox is that […] Continue reading
