    I dare say one of the greatest discoveries could be gravitational radiation from the BB and probable Inflation itself!

    I see the Livingstone detector has a '' 25 percent greater sensitivity'', wonder why they didn't increase the sensitivity of the other detector? Although it's planned for the future.
    I'm thinking as long as they detect an event on both, then it's a bonus to get a little more detail/ definition.
    They say the increased sensitivity will increase the range. I think, if Livingston detects an event beyond the reach of the Hanford detector, then you may be wondering if it counts, since it's not a 'joint' detection so to speak.
    Interesting times ahead.

    The checking of data from the LIGO first run (O1), shows no ''significant evidence'' of GWs from pulsars.
    Let's hope better luck next time with the more sensitive upgrade made for O2 which started last november 30th and looks like running until april / may this year.

    Thanks for the latest news sweetpea:
    The discovery and confirmation of gravitational waves and BH's can never be underestimated.

    I should have said what I'm waiting for. I want to see if their talking of a possible detection of the same event on all three detectors... LIGO and Virgo. Perhaps more than one event caught on all three.
