LIGO - http://en.wikipedia.org/wiki/LIGO
LIGO, which stands for the Laser Interferometer Gravitational-Wave Observatory, is a large-scale physics experiment aiming to directly detect gravitational waves. Cofounded in 1992 by Kip Thorne and Ronald Drever of Caltech and Rainer Weiss of MIT, LIGO is a joint project between scientists at MIT, Caltech, and many other colleges and universities. It is sponsored by the National Science Foundation (NSF). At the cost of $365 million (in 2002 USD), it is the largest and most ambitious project ever funded by the NSF.
Observations at LIGO began in 2002 and ended in 2010; no unambiguous detections of gravitational waves have been reported.
Din pacate se pare ca in urma experimentelor care au durat 8 ani au constatat ca undele gravitationale nu exista. Deci nu este vorba de aparatul matematic sau de formule ci de realitatea undelor gravitationale ... in spatiul 3D |
Although people have made LIGO-type detectors since the '70s, the first large scale ones only came into operation around 2000. Our first generation of LIGO ran from 2002 to 2010. We knew that that detector didn't have a great chance at detecting signals, but we wanted experience with the technology and the engineering challenges. We searched, but we didn't find anything.
But we are just now finishing up the instillation of the second generation detector. And we expect that, starting late next year, we'll be able to directly detect gravitational waves for the first time. We estimate that we'll have at least several detections per year, and that there will be some that will come in with enough signal amplitude that we'll be able to use those gravitational waves to do some very interesting astrophysics.
LIGO sus LIGO jos, repeți același cuvânt ca un disc stricat dar habar nu ai cum funcționează sau despre ce este vorba.
