Detection of gravitational waves

Click For Summary
Current gravitational wave detection is primarily conducted by LIGO, which has only managed to set upper limits on wave magnitudes. The next-generation LISA will enhance sensitivity, focusing on events like mergers of massive objects, particularly black holes. There is confidence in the feasibility of direct detection, although challenges remain due to the required sensitivity and the distance of detectable events. The gravitational wave amplitude diminishes with distance, complicating detection, especially for neutron star mergers, which may only be observable within our galaxy. Overall, advancements in technology and theory suggest that significant breakthroughs in gravitational wave detection could occur in the near future.

Would a neutron star collapse to a BH through accretion produce detectable waves?
I think that would depend upon how far away it would be. I honestly don't know how far away we could detect such events.

Well, maybe we'll all get lucky. Stranger things have happened... Maybe there are two 100x or more stellar mass BH's a 10 ly or so away about to merge perfectly perpendicular to the plane of LIGO! Fingers crossed everyone!

Hey, maybe this is the 2012 issue those lunatics go on about. We'll get full confirmation of GR/QM, then immidiately be accreted. :smile:

LOL Now that is an end of the world I would buy tickets for. I'd just hope we get slung into deep space... a literal spaceship earth.
