放松，看着两个黑洞合并。受到2015年首次直接探测到引力波的启发，这个模拟以慢动作播放，但如果实时运行，则需要大约三分之一秒。在宇宙的舞台上，黑洞被放置在恒星、气体和尘埃的前面。它们的极端引力将它们背后的光透镜成爱因斯坦环，当它们螺旋地靠近并最终合并成一个。当大质量物体迅速合并时产生的不可见的引力波导致可见图像在爱因斯坦环内外波动和晃动，即使在黑洞合并之后也是如此。LIGO探测到的引力波被命名为GW150914，与距离13亿光年的36和31个太阳质量黑洞的合并相一致。最后一个黑洞的质量是太阳的63倍，剩下的3个太阳质量转化为引力波辐射的能量。今天的事件视界：这是美国宇航局的黑洞周！

Relax and watch two black holes merge. Inspired by the first direct detection of gravitational waves in 2015, this simulation plays in slow motion but would take about one third of a second if run in real time. Set on a cosmic stage, the black holes are posed in front of stars, gas, and dust. Their extreme gravity lenses the light from behind them into Einstein rings as they spiral closer and finally merge into one. The otherwise invisible gravitational waves generated as the massive objects rapidly coalesce cause the visible image to ripple and slosh both inside and outside the Einstein rings even after the black holes have merged. Dubbed GW150914, the gravitational waves detected by LIGO are consistent with the merger of 36 and 31 solar mass black holes at a distance of 1.3 billion light-years. The final, single black hole has 63 times the mass of the Sun, with the remaining 3 solar masses converted into energy radiated in gravitational waves.
