    Fascinating stuff...

    LIGO Hears Gravitational Waves Einstein Predicted - Video - NYTimes.com
    http://nyti.ms
    About a hundred years ago, Einstein predicted the existence of gravitational waves, but until now, they were undetectable.

    I'll stick to Star Trek please.

      Ha!

      I'm really curious now where this confirmation takes us next...

        Although most people will naturally focus on the physics achievement - confirmation of the existence of gravitational waves predicted in 1916 by Albert Einstein on the basis of his theory of general relativity - I am particularly impressed with the instrumental part. Measuring a positional change of 10,000 times smaller than a proton is a an unbelievable achievement. Some audiophiles will be very proud - the some basic interferometry technique used in LIGO has been used to develop their speakers. B&W has been using this technique since the early 70's - Peter Fryer, their research director has been a pioneer in the field of laser interferometry applied to speakers.
        My opinions rely on listening mainly to acoustical, non amplified music. I do not care about electronic music or listening to rock at stadium levels, but I enjoy Mahler and Shostakovitch.

            Von Schweikert told me a story of how before LIGO all he could do was watch drivers with a strobe light synched and a frequency generator to observe driver diaphragm behavior. Times have changed a lot since the 70's.

              This piece puts it in a little better perspective for the layperson!

              Astronomers have finally found evidence of gravitational waves. Now things can get interesting.
