The Speed of Light

Posted on February 13, 2017 by Haley's Comet

Growing up I had frequently heard the phrase “Faster than the speed of light” but until now, I had no idea what that truly meant. Prior to this class, all I knew was that faster than the speed of light meant FAST, and that all human travel was slow in comparison. In fact, according to… Continue reading The Speed of Light Continue reading →

Posted on February 2, 2017 by brynnabhall

When considering the greater span of history, starting with my first Astronomy class taught by Professor Weintraub “How Old Is the Universe?” the concept of the nature of time in space has fascinated me. I think part of this relates to the fact that I am a history major and a history buff, and therefore … More Our Miniature History, the Cosmic Calendar, and Understanding One’s Place Continue reading →

The Fermi Paradox

Posted on April 30, 2016 by alecsolarsystem

Dating the Solar System?

Posted on March 15, 2016 by samihahplanet

No,  I’m not referring to taking our Solar System out to a romantic dinner and movie. What astronomers and physicists are interested in is the age of our Solar System. And given the vastness and inaccessibility of most of the Solar System, revealing the true age of it has proven to be quite the challenge. Astronomers have, however, been able to […] Continue reading →

Getting really really lucky, or discovering the secret to warp travel

captain’s blog, Stardate 69668.2 This blog post is of the unrestricted variety, so naturally I will take this opportunity to talk about science fiction. One of my favorite things about sci-fi movies is how frequently (and casually) characters from Earth encounter other intelligent species. Or maybe even other species live with us humans here on Earth. […] Continue reading →

Why We Should All Love Earthquakes

Posted on March 15, 2016 by 2016spaceodyssey

Earthquakes are one of the most obvious consequences of Earth’s plate tectonics.  The crust slowly moves along the with the “current” of the mantle as the Earth surface constantly rearranges itself.  Without plate tectonics, it is very possible that life could not have taken a foothold on Earth.  On Mars, which does not have plate […] Continue reading →
