SAMPLE ALL THE FLAVORS!Increasingly, Vanderbilt instructors are incorporating blogs into their course design. Course Blogs at Vanderbilt is a mash-up of live feeds representing a wide variety of Vanderbilt courses that use blogging to help students reflect on, comment about, and introduce new ideas to course material. Click on the blog title to view the originating course blog. You can also click on the Participating Blogs tab for links to each blog.

Before sending the Voyager spacecraft off into space in 1977, Carl Sagan and his team insisted on including a “bottle” to send off into the “cosmic ocean.” This message to potential intelligent life in the universe is contained in the Voyager record, a 12 inch golden record meant to encapsulate life on Earth. The record […] Continue reading → Continue reading
To be, or not to be? Is that really the question? According to the Fermi Paradox, it’s a perfectly valid one. The Fermi Paradox, coined after Enrico Fermi, is a theory that addresses life elsewhere in the universe as a probable reality. The only issue is, however, that no other forms of life (that we […] Continue reading → Continue reading
Time can be lost. Time can be wasted. Time can be saved. Time can be valuable. Time is of the essence. Perhaps a less known is the fact that time can be dilated! What exactly does this mean? It means that differences of elapsed time for someone traveling at high velocity or in the vicinity […] Continue reading → Continue reading
Source: Youtube Channel Kurzgesagt The Fermi paradox is summarized in the video above. At a bare minimum, the Fermi paradox is the paradox of the Drake equation supposedly estimating a large number of possible planets in our Galaxy harboring life, yet no such evidence of intelligent life has been discovered. There are many possible speculations for why […] Continue reading → Continue reading
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 […] Continue reading → Continue reading
Although SETI institute was founded in 1984, the search for extraterrestrial life concerned scientists for many years prior. In 1977, Ohio State’s Big Ear radio telescope heard exactly what it had been searching for: the “Wow!” signal. The radio telescope was attempting to detect radio waves around the three-star system, Chi Sagittarii, when it detected radio […] Continue reading → Continue reading
In 2012, Philip Metzger and some of his colleagues from the Kennedy Space Center worked on a paper theorizing how we could “bootstrap” our way across the Solar System. The first step of their plan was to get materials to the Moon’s surface. From there, development of the industry would continue as the field of robotics has… Continue reading → Continue reading
One of the biggest problems that we have when it comes to interstellar travel is that we don’t have a spaceship that can go fast enough to get us where we want to go in a reasonable time. Luckily, we have some really smart scientists trying to come up with ways to make a really […] Continue reading → Continue reading
What a cutie Tardigrades, aka Water Bears, aka Moss Piglets, are the most resilient species on Earth. They transcend the extremophile label. Many extremophiles are only able to thrive in their own extreme environment. Tardigrades can live in almost every extreme environment. They’ve been known to survive temperatures ranging from 1 kelvin above absolute zero […] Continue reading → Continue reading
The use of anti-matter propulsion might be the key to interstellar travel. Anti-matter is basically normal matter that has opposite charges. When matter and anti-matter collide with one another, they annihilate one another and energy is released. Unlike with nuclear fusion, where only 3% of the total mass of the matter is converted into energy, […] Continue reading → Continue reading
