    Here, you can find the paragraph below:
    But I don't understand how a non-detection can mean the detection pf gravitational waves!
    Anyone knows what's the point?
    Thanks

    I don't think that's what they are saying. LIGO did not detect any gravitational waves, therefore, the authors ruled out a neutron-star merger as a source for GRB 070201; however, in order for this conclusion to hold any water, LIGO has to prove that it CAN observe gravitational waves. LIGO has to, at some point, detect SOME gravitational waves before we can use this conclusion with confidence.

    I'm not sure why you think this paragraph is saying a non-detection is a detection. It is not.
