Extraterrestrial Civilizations: The Drake Equation
We all love hearing stories about aliens and extraterrestrials. But what if I told you that there is a probabilistic equation that is used by scientists to estimate the amount of active and communicative extraterrestrial civilizations there are in the Milky Way. It is called the Drake Equation and it was made by Frank DrakeContinue reading “Extraterrestrial Civilizations: The Drake Equation” Continue reading

SETI isn’t Science: Why the Search for Aliens is a Waste of Resources
The Search for Extraterrestrial Intelligence (SETI) has been ongoing for about 60 years now, and it’s time to reconsider if it’s worth the millions of dollars and hours it burns every year. To start off, I want to make the case that SETI isn’t real science. It’s a faith-based effort that isn’t falsifiable. An article … Continue reading SETI isn’t Science: Why the Search for Aliens is a Waste of Resources → Continue reading
The Drake Equation
We hear about aliens all the time, whether in books or movies or tv shows, and this leads us to ponder our own existence. Are we alone, or is there other life out there? This is a question that has plagued mankind since begun exploring interstellar space, and started looking for life in our own … Continue reading The Drake Equation Continue reading

The “Archaeological-Form” of the Drake Equation
The Revised Equation The Drake Equation is a very useful tool to speculate on one of the most intriguing questions of all time: are there other intelligent lifeforms out there in the universe? The equation helps to predict the odds of the existence of other civilizations. It is all still speculation, but recently … Continue reading The “Archaeological-Form” of the Drake Equation → Continue reading

The Drake Equation
The Drake Equation is a formula that is commonly used to stimulate discussion of the possibility of extraterrestrial life- not to necessarily quantify the number of communicating civilizations. The Drake Equation uses many variables to quantify estimates for the number of communicating civilizations, but a number of them are quite controversial as they are not […] 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

The origins of life and the Drake equation
In using the Drake equation to discuss and estimate the probability of non-Earth life in our universe, one factor we estimated was the probability of life developing on a given planet in the habitable zone. The problem with making such an estimate as students in an Astronomy 201 course, of course, is that we all…

Are We Alone?
The famous science fiction writer Arthur C. Clarke was quoted as saying, “Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.” A truer statement is hard to come by. Yet quote also sparks tremendous debate and intrigue among those whose ears come across it for the … Continue reading Are We Alone? →

Impacts on Saturn and the Drake equation
NASA’s Cassini spacecraft recently observed meteors colliding with Saturn’s thin rings. This marked the first direct evidence of small meteoroids breaking into streams of rubble and crashing into Saturn’s rings, although astronomers already expected this to be occurring regularly. However, specific details of such impacts were merely speculation, much of which is cleared up via […]

The Drake Equation – A Scientific Shot in the Dark
The Drake Equation is an incredibly interesting topic of discussion. Obviously, determining the number of communicating civilizations in our galaxy is a monumental task. Because of the sheer size of the problem, the fact that a simple equation can bring us anywhere close to a reasonable guess is in itself very impressive. As impressive as […]
