Will the advanced LIGO team announce the discovery of gravitational waves by end of March?
The Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) re-opened in September 2015 after a significant upgrade.
Designed with 10x greater sensitivity and a wider range of covered frequencies than the original LIGO, advanced LIGO should, according to its designers, have an "enhanced physics reach that during its first several hours of operation will exceed the integrated observations of the 1 year LIGO Science Run."
A full description of the experiment in gory detail can be found here.
Calculations of the expected detection rates suggest tens and potentially hundreds of detectable events per year under reasonable assumptions about neutron star and other types of binaries (and of course assuming General Relativity is correct, etc.)
Rumors have been flying that detections have happened.
Will the LIGO experiment publicly announce a 5-sigma (or equivalent) discovery of astrophysical gravitational waves by March 31, 2016?
Metaculus help: Predicting
Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.
The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available. With tachyons you'll even be able to go back in time and backdate your prediction to maximize your points.
The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.
Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.
Note: this question resolved before its original close time. You earned points up until the question resolution, but not afterwards.

Metaculus help: Community Stats
Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.
When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
