Is the detection of gravitational waves a reality with nowadays technology? Are there recent news?

  • $\begingroup$ I see there was a question very similar to this. Sorry. It looks like there are no (detectable) gravity waves yet, out there. Correct ? $\endgroup$ – user6090 Dec 19 '11 at 20:55

    $\begingroup$ If there were, it would be covered in the news by a bunch of journalists who have no clue what they're talking about. $\endgroup$ – endolith Dec 20 '11 at 20:53
  • $\begingroup$ Comment to the question (v1): It seems this post is conflating gravity waves and gravitational waves. Related for the latter: physics.stackexchange.com/q/10161/2451 $\endgroup$ – Qmechanic Aug 30 '12 at 6:12
  • $\begingroup$ (Advanced) LIGO has, on 11 February 2016, announced detection of gravitational waves from a binary black hole merger with more than $5\sigma$ certainty. $\endgroup$ – Danu Feb 15 '16 at 0:02

Unfortunately gravitational waves have not been detected yet.

There is a number of Earth-bound detectors planned and already in operation (e.g. LIGO, Geo 600, Virgo, Nanograv and others). As for space-borne detectors, ESA works on Next Gravitational-Wave Observatory after NASA pulled out of LISA project in April 2011 due to funding problems. Joint NASA/ESA mission, LISA Pathfinder will launch in June 2013 testing technologies to be used by NGO.

Keep an eye on the pages and blogs of these projects if you'd like to stay up to date on their progress. Also, if gravitational waves are detected, the discovery will no doubt be announced here and even here.

  • $\begingroup$ Maybe we should update this answer with the correct one? $\endgroup$ – Trader Apr 5 '16 at 15:03
