    Awesome blog post over at

    There are lots of images and much more posted explaining a lot of cool stuff. Definitely click the link if you are interested in understanding gravitational waves and detecting them.


    A Spectacular Chance for Gravitational Waves

    One of the most spectacular and successful ideas of the 20th Century was Einstein’s General Relativity, or the idea that matter and energy determines the curvature of spacetime, and the curvature of spacetime in turn determines how gravitation works.

    From the orbits of planets to the bending of starlight, General Relativity governs all gravitational phenomena in the Universe, and accurately describes every observation we’ve ever made.

    And the more concentrated energy is — in any form — in a given region of spacetime, the more severe the curvature that results. This means that if we can probe systems that are more extreme than we find in our own Solar System, we can potentially observe some aspects of General Relativity that are only theoretical predictions at this time.
