模擬兩個黑洞合併
Simulation: Two Black Holes Merge
發表日期：2024-05-10
放鬆觀看兩個黑洞合併。受 2015 年首次直接探測到引力波的啟發，這個模擬以慢動作播放，但如果實時執行，則需要大約三分之一秒。在宇宙舞臺上，黑洞被擺放在恆星、氣體和塵埃面前。隨著黑洞的螺旋式靠近，它們的極端引力將來自它們身後的光線透射成愛因斯坦環，最終合二為一。大質量天體快速凝聚時產生的引力波本來是不可見的，但它會導致可見影像在愛因斯坦環內外產生漣漪和晃動，即使在黑洞合併之後也是如此。LIGO 探測到的引力波被命名為 GW 150914 ，與距離 13 億光年的 36 個和 31 個太陽質量黑洞的合併相吻合。最終的單一黑洞的質量是太陽的 63 倍，剩餘的 3 個太陽質量轉化為引力波輻射的能量。 今天的地平線事件：美國國家航空航天局（NASA）的黑洞周！
原文：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.
