Exciting news: Gravitational Waves detected!
We want to share our excitement about the first-ever direct detection of gravitational waves! The event happened right before the beginning of the first observing run of the advanced LIGO detectors, on 14 September 2015. The waves were generated as two black holes merged into a single black hole about 1.3 billion light years from Earth. In astronomy units this is 410 Mpc, approximately 10% of the way across the visible Universe!
Just as exciting: this is also the first-ever observation of binary black holes. In fact, since black holes are black, and emit no light or electromagnetic radiation, this is the only way we can see them.
Did Einstein@Home play any role in this? No, it didn’t. The signal in the instrument lasted only about 1/4 of a second. It’s not a continuous-wave signal like the type that Einstein@Home has been searching for. But since the observing run ended in mid January, we have been preparing the data to start a new low-frequency all-sky search for continuous gravitational waves. We are now starting to run this on Einstein@Home, so please sign up your computers and disable their sleep mode! In the next months we will extend the frequency range of the continuous waves all-sky searches, target interesting point sources and we are also gearing up to perform broader surveys for binary black hole mergers.

EAH没有在这次的探测中发挥作用。虽然引力波发现了，但是EAH还是会继续运行。
这次观测到的是短时间的(大概1/4秒)信号，而EAH试图寻找的是持续的引力波信号。
想问问：引力波已经被发现了，你们还会继续跑吗？ |

与光速一致
