Um das zu beobachten, stell dir vor, dass die Distanz zwischen uns und Proxima Centauri und die Größe eines menschlichen Haares verändert hat. Das ist der Level der Präzision, die LIGO beobachtet hat. Wenn das nicht eines der erstaunlichsten Feats in der historischen Geschichte ist, weiß ich nicht, was es ist. Und das war nur die erste gravitationelle Wave, die LIGO entdeckt hat.

Die zweite Entdeckung geschah drei Monate später, im Dezember 2015. Das Signal kam auch aus einem Black Hole Merger, der 1,4 Billionen Lichtjahre entfernt war. Über seine ersten drei Runden hat LIGO mehr als 80 Black Hole Mergers gedreht. Und im August 2017 entdeckte es den Merger von zwei Neutronensternen.

Named GW170817, this signal was notable for being the first gravitational wave to be corroborated by electromagnetic observations from 70 observatories across the planet. This was a breakthrough, not only in gravitational wave detection, but in multi-messenger astronomy. It turns out, LIGO was just warming up during these three runs.

As of May 2023, LIGO has begun its fourth run with better sensitivity than ever. After its latest round of upgrades, which kept LIGO offline for three years, the observatories now have more reflective mirrors, better mirror suspension and improved light squeezing with lower quantum uncertainty. And this time, LIGO also has the support of CAGRA, a new interferometer observatory in Hida, Japan.

Chagra befindet sich im Untergrund, macht es die weltweit erste subterranische Gravitations-Wave-Observatorie und auch die erste, die cryogenische Fenster benutzt. During an engineering run on the 18th of May, LIGO scientists say they already received a signal that was possibly caused by a neutron star being swallowed by a black hole.

We'll have to wait a while for confirmation, but if these early results are any indication, LIGO is about to blow the doors off our understanding of gravitational wave generating phenomena. So, what other developments lie ahead? India is preparing a collaborative project called LIGO India, or Indigo, which will help LIGO triangulate better location data.

In 2027 to 2028, LIGO will implement its LIGO Voyager upgrade, which will achieve higher sensitivity with four times heavier mirrors and higher frequency lasers. And in the more distant future, A third generation facility has been proposed, called Cosmic Explorer. This facility would feature two new observatories, with arms spanning 40 km and 20 km respectively.
