Kessel Run in Twelve Parsecs

Posted on January 23, 2018 by Nathan Xiao

The speed of light is one of the few constants in our universe that we consistently look to when it comes to space. It is an astronomical measurement that we only dream of achieving. Seeing the Millennium Falcon shift into overdrive or the Enterprise slip into hyperdrive are only distant fantasies for us Earth-bound creatures. … Continue reading Kessel Run in Twelve Parsecs → Continue reading →

Putting the speed of light into perspective

Posted on January 23, 2018 by terranojm

The theory of special relativity tells us that there is an absolute speed limit in the universe, that being the speed of light. At a speed of about 300,000 km/s, light takes only one second to travel to the Moon from Earth and eight minutes to travel to the Sun from Earth. This speed is … Continue reading “Putting the speed of light into perspective” Continue reading →

Space Bubbles AKA Quantum Foam

Posted on March 13, 2016 by astr2110geoffren

Spacetime is often described as a “fabric”, but there is one theory that would describe it as more like sea foam- made of a bunch of tiny bubbles. This is the quantum foam theory. The quantum foam theory basically came into existence to try and unite Einstein’s theory of relativity and quantum mechanics, something that […] Continue reading →

Holes and Wrinkles

Posted on April 28, 2013 by ibrahim2016

There is a lot of misconception about two of the more arcane forms of proposed space travel: Warp Drives and Worm Holes. They work on the same principles but function in wholly different ways. General Relativity explains that any mass or energy can bend space and time. Since there is energy everywhere space and time […] Continue reading →

To Stretch or Not To Stretch

Posted on February 1, 2013 by ibrahim2016

Physics has the distinction of hosting the one of the weirdest concept hierarchies  Don’t get me wrong: physics is beautiful in its intricate connections. But sometimes, especially in the case of modern physics, one feels something like: So, most of us know about special relativity. A quick summary for the unfortunate: Special relativity establishes the speed […] Continue reading →

Scale, Relativity, and the Power of 10

Posted on January 26, 2013 by sharpew

For my first official blog post, I’d like to write about the Powers of Ten video, and the subsequent site I came across because of it. Although I have seen the Powers of Ten video in a class several years ago, watching it again filled me with the same sense of curiosity and amazement as […] Continue reading →
