Gravitational radiation has been directly detected. The first-ever detection was made by both facilities of the Laser Interferometer Gravitational-Wave Observatory (LIGO) in Washington and Louisiana simultaneously last September. After numerous consistency checks, the resulting 5-sigma discovery was published today. The measured gravitational waves match those expected from two large black holes merging after a death spiral in a distant galaxy, with the resulting new black hole momentarily vibrating in a rapid ringdown. A phenomenon predicted by Einstein, the historic discovery confirms a cornerstone of humanity’s understanding of gravity and basic physics. It is also the most direct detection of black holes ever. The featured illustration depicts the two merging black holes with the signal strength of the two detectors over 0.3 seconds superimposed across the bottom. Expected future detections by Advanced LIGO and other gravitational wave detectors may not only confirm the spectacular nature of this measurement but hold tremendous promise of giving humanity a new way to see and explore our universe.

重磅消息！引力輻射已被直接探測到！去年九月，華盛頓和路易斯安那州的激光干涉引力波觀測台（LIGO）雙方設施迎來歷史性時刻，同時捕捉到這一信號。經過多次一致性檢查，最終以5-sigma的成果發佈。測量到的引力波與來自遙遠星系中兩個大型黑洞合併後所預期的波形相符，隨後產生的新黑洞瞬間在快速的振蕩中回響。這一現象是愛因斯坦所預測的，標誌著人類對引力和基本物理學理解的基石獲得確認。這也是有史以來最直接的黑洞探測！插圖展示了兩個合併黑洞的模樣，以及在0.3秒內兩個探測器的信號强度。未來高級LIGO和其他引力波探測器的檢測，將不僅確認這一壯觀的測量，還可能為人類探索宇宙提供全新的視角和方式。
