I think of gravitomagnetism as as the "magnetic" portion of gravity, with gravity being the "electric" portion. Since gravity ("electric") seems to affect space (which the LIGO could detect) what does the gravitomagnetic portion affect? Was it not detected or did the LIGO respond to both components?

    $\begingroup$ While you may think of things that way, I don't believe that the framework for GR does, so you probably need to clarify how what you are asking corresponds to GR. $\endgroup$ – Jon Custer Mar 8 '16 at 21:05
  • $\begingroup$ "This apparent field may be described by two components that act respectively like the electric and magnetic fields of electromagnetism, and by analogy these are called the gravitoelectric and gravitomagnetic fields, since these arise in the same way around a mass that a moving electric charge is the source of electric and magnetic fields.
