What happens when two black holes collide? This extreme scenario likely occurs in the centers of some merging galaxies and multiple star systems. The featured video shows a computer animation of the final stages of such a merger, while highlighting the gravitational lensing effects that would appear on a background starfield. The black regions indicate the event horizons of the dynamic duo, while a surrounding ring of shifting background stars indicates the position of their combined Einstein ring. All background stars not only have images visible outside of this Einstein ring, but also have one or more companion images visible on the inside. Eventually the two black holes coalesce. The end stages of such a merger may provide a strong and predictable blast of gravitational radiation, a much sought after form of radiation different than light that has never yet been directly observed.

當兩個黑洞碰撞時，會發生極端而壯觀的事件，這種情況可能在一些合併的星系和多星系系統的中心出現。特定的影片展示了這種合併的最後階段的計算機動畫，同時突顯了出現在背景星空中的引力透鏡效應。
黑色區域代表著這對動態雙黑洞的事件視界，而周圍不斷變化的背景星星環則顯示了它們合併後的愛因斯坦環的位置。所有背景的星星不僅可以在這個愛因斯坦環之外看到影像，還可以在裡面看到一個或多個伴隨影像。最終，這兩個黑洞合併在一起。
這種合併的最後階段可能會提供一個強烈且可預測的引力輻射爆發，這是一種與光不同的輻射，至今尚未被直接觀測到。
