    Puffs of smoke waft from a circuit board as interns solder tiny circuits for the Evolved Laser Interferometer Space Antenna. "We're looking for evidence of black holes," Robert Buttles said.


    "As of now we only have images of material spinning around a black hole, but we haven't been able to physically measure the black hole itself."


    Pairs of black holes radiate gravitational waves as they orbit each other in a binary system. Analyzing these waves can allow scientists to study black holes directly.

    "All other emission from a black hole binary is actually from material around the black hole-for example, gas falling into the black hole from an accretion disk and generating x-rays-but not [data] from the black hole itself," said Jeffery Livas, an astrophysicist working on the eLISA.

    yeah, on the other site,
    on danshawen's topic
    http://www.physforum.com/index.php?showtopic=55414&st=0&#entry665341
    ,
    i pointed these facilities out.
    they are designed to pick up gravitational radiation.

    i actually said,

    " there's a gravitational spectrum.
    also look into advance ligo.
    for now there's lisa, elisa, nanograv 2015 and nonograv.
    there's also,
    virgo and advance virgo and geo600 "

    Still a crying shame that NASA needed to withdraw from its partnership with the original "LISA" mission due to those two horrible variables of economics and politics.

    Reminds me of that other mission the "SSC" that was cancelled in the early 90's.

    a mother space craft and two daughters
    will not happen as of now.
    or as of yet anyways.
    esa also states it will be less sensitive now also.

    From memory in the original mission, [LISA] the three space craft were to form a triangle with arms around a million kms long.

    also look into something called boom tubes.
    and the MMS,
    magnetospheric multiscale mission

    reminds me of GRAIL mission for moon

    Could this experiment ever be revived?
    From memory, it was to be far bigger then the LHC.
    What stage of completion was ever reached?

    The LPF (Lisa Path Finder) proof of concept mission is still planned for launch for July 2015. Now thou Obama can't just stop NASA from working because budget didnt get approved, it's all in ESA hands now. http://www.esa.int/Our_Activities/Space_Science/LISA_Pathfinder_overview. LPF is one spacecraft of the original 3 spacecraft required configuration in LISA.

    Thanks "Youreyes"
    I was referring though to the SSC.

    I'll go make that clearer in the appropriate post.

    The Superconducting Super Collider (SSC) which was being built around Waxahachie, Texas(just South of Dallas/Fort worth) was nixed on October 21, 1993.
    Supposedly, it was either finish the SSC or fund the International Space Station...

    Thanks for that.
    Rather sad that once again, politics and economics must curtail potential groundbreaking scientific experiments such as this would have been.
    Maybe a time in the future will see those two horrible variables, as being far more positive, to the scientific disciplines, as science in general, continues to weave its wonders and revelations.

    Before it was nixed, many people were forced off their land.

    Were they compensated for it?
    I know it doesn't solve all problems, but sometimes we need to be realistic about the march of progress.
    Just a pity in this instance, that short sighted politicians decided to pull the pin.

    Well the super collider was built only over in Europe for 10 billion dollars which was less than the one that was supposed to be built in America. The cost was always rising and as was pointed out the last estimate was for 4 billion dollars more in cost increases and that was only the beginning of cost overrides. That collider is working and has found some break through particles so science research is and will continue only in other countries not just in America.

    Could you post a link about them being forced off and not paid to move?
