这是迄今为止测量到的最强的引力波信号——它显示了什么？GW250114是今年早些时候由位于美国华盛顿和路易斯安那州的激光干涉引力波天文台（LIGO）的两个臂探测到的。分析表明，这一事件是由两个质量约为太阳质量33倍的黑洞合并成一个质量约为太阳质量63倍的更大黑洞造成的。尽管这一事件发生在大约10亿光年之外，但信号是如此强烈，以至于所有黑洞的旋转，以及最后一个黑洞的初始响铃，都被推断得异常准确。此外，正如之前预测的那样，它比以前更好地证实了合并黑洞的总视界面积大于合并黑洞的视界面积。一位艺术家的插图描绘了一个富有想象力和概念性的观点，从碰撞前的一个黑洞附近。

It was the strongest gravitational wave signal yet measured -- what did it show? GW250114 was detected by both arms of the Laser Interferometer Gravitational-wave Observatory (LIGO) in Washington and Louisiana USA earlier this year. Analysis showed that the event was created when two black holes, each of mass around 33 times the mass of the Sun, coalesced into one larger black hole with a mass of around 63 solar masses. Even though the event happened about a billion light years away, the signal was so strong that the spin of all black holes, as well as initial ringing of the final black hole, was deduced with exceptional accuracy. Furthermore, it was confirmed better than before, as previously predicted, that the total event horizon area of the combined black hole was greater than those of the merging black holes.
