To Serve Man
Twilight Zone, one of the favorite t.v. series growing up. My favorite episode, the one that really stuck with me, was “To Serve Man”. In this episode, Aliens come to Earth with seemingly peaceful and helpful intentions. They just want to help and serve man. Plot twist: they were serving man alright… for dinner. This […] Continue reading

Blog 7 – Interplanetary Life Travel
From the title, you might think the subject of this blog is about human space travel, something that isn’t very developed today. However, it is possible that some life forms before us have experienced travel between the planets. There are theories that support the idea that life originated on either Venus or Mars, and then […] Continue reading

Blog 7: Wait But Why
Where is everybody? That is essentially the question asked in the Fermi Paradox. Compared to Earth and our solar system, the universe is extremely vast and extremely old. Surely there must be intelligent life somewhere within the depths of the unexplored universe? The Drake Equation (written as N = R* • fp • ne • fl • fi • fc • … Continue reading Blog 7: Wait But Why Continue reading

The Fermi Paradox
“Where are they?” asked Enrico Fermi to his colleagues in 1950. Where is all the life that, by all rights, should populate our galaxy and the rest of the universe? The Fermi Paradox arises from the knowledge that the whole of human history is but a blip in the cosmic calendar. If we have so […] Continue reading
Drake Equation
You may have heard of the Drake equation before, and you may have heard that it can “predict” the number of aliens we may one day face (or fight?). Well, you’re not too far off. The Drake equation allows astronomers and scientists to estimate the number of civilizations that exist in the deep vast space […] Continue reading
Blog 7: Last Universal Common Ancestor
The Last Universal Common Ancestor, LUCA, was a microbe that live around 4 billion years ago. It is believed that it is anaerobic and autotrophic, not breathing and making its own food. There is also evidence it live near iron-sulfur rich hydrothermal bents deep underground. it would have possessed a metabolism dependent upon hydrogen, carbon […] 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 […] Continue reading
The Fermi Paradox
The Fermi paradox is based entirely upon a lunch conversation between Enrico Fermi, an iconic physicist, and his friends and co-workers. When discussing their belief that there must be intelligent life elsewhere in the universe, Fermi asked a simple, but profound question: “Where is everybody?” While, on its surface, this question seems somewhat ridiculous, it […] Continue reading
Hello?
Is anybody out there? There are only two answers to this question: yes, or no. And it’s hard to say which one is scarier. For as long as we have studied and understood the cosmos, this question has constantly pelted our curious minds. Amidst the dark, cold, corridors of space, on a small ball of […] Continue reading
