人类首次直接探测到了引力波_科技_腾讯网

这次探测到的引力波是由13亿光年之外的两颗黑洞在合并的最后阶段产生的。两颗黑洞的初始质量分别为29颗太阳和36颗太阳,合并成了一颗62倍太阳质量高速旋转的黑洞,亏损的质量以强大引力波的形式释放到宇宙空间,经过13亿年的漫长旅行,终于抵达了地球,被美国的"激光干涉引力波天文台"(LIGO)的两台孪生引力波探测器探测到。 根据广义相对论,该双星系统会以引力波的形式损失能量,轨道周期每年缩短76.5微秒 1974年物理学家约瑟夫・泰勒(Joseph Hooton Taylor, Jr)和拉塞尔・赫尔斯(Russell Alan Hulse)发现了一颗编号为PSR B1913+16的脉冲星,他们发现该脉冲星处于双星系统中,其伴星也是一颗中子星。根据广义相对论,该双星系统会以引力波的形式损失能量,轨道周期每年缩短76.5微秒,轨道半长轴每年减少3.
