黑洞黑洞blackhole广义相对论所预言的一种天体。一个质量比太阳大8倍以上的恒星，一般经过超新星爆发留下超过二、三个太阳质量的核，将没有任何力能阻止它继续坍缩。当它的半径小于引力半径rg＝2GM/c2（G为万有引力常数，c为光速，M为天体的质量）时，没有任何物质或辐射能够逃逸出来，成为黑洞。黑洞的性质由三个参量来表征，即质量M、角动量J和电荷Q。当J＝Q＝0时，它是球对称的史瓦西黑洞；当Q＝0时，则为轴对称的克尔黑洞。黑洞的性质决定了探测黑洞的困难性。如果向黑洞下落的气体具有较大的角动量，则应绕着黑洞在轨道上旋转，形成一个气盘。气盘中相邻层之间因气体的粘滞性引起的摩擦产生了热能，理论计算表明，气盘应具有很高温度，在X射线波段产生辐射。另一方面，黑洞的质量应大于中子星的质量上限，能够精确确定质量的是双星系统。因此，最有希望找到黑洞的是大质量X射线双星，尤其是天鹅座X-1。这是一个X射线变源，它有一个光学对应体，从这个9等超巨星的光谱得到视向速度的周期性变化，暗示一个不可见伴星的存在。进一步算出它的质量大于4太阳质量，很可能是8太阳质量，大于中子星的上限2～3太阳质量；另一个有希望的黑洞候选者是大麦哲伦云X-3，它也是一个X射线双星，其中不可见天体的质量也是8太阳质量。
