[漢羅] 模擬動畫：兩粒烏洞合併

來！放予輕鬆，咱來看兩粒烏洞合併 ê 動畫。 這支動畫是照 2015 年頭一擺 直接量著 重力波 ê 概念做–ê，模擬動畫是慢動作放送，實際上這規个過程才 3 分 1 秒 ê 時間爾爾。 Tī 這个宇宙舞台，烏洞 tī 頭前，後壁 是 恆星、氣體、kah 塗粉。 兩粒烏洞那踅倚那合併，落尾就合併做一粒。 In 強大 ê 引力 kā in 後壁 ê 光 拗彎做 愛因斯坦環。 烏洞 合併了後，會予本底看袂著 ê 重力波，因為大質量天體 快速合併，造成看會著 ê 影像會 tī 愛因斯坦環 內底 kah 外口產生波動。 LIGO 雷射干涉引力波天文台 量著 ê 重力波 叫做 GW150914，是 tī 13 億光年遠 ê 36 倍 太陽質量 kah 31 倍太陽質量 ê 烏洞合併產生–ê。 落尾，孤一粒烏洞變做是 太陽質量 ê 63 倍大，其中 3 个太陽質量轉做 重力波 輻射 ê 能量。

[English] Simulation: Two Black Holes Merge

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.
