黑洞一直是天文物理學上最神秘的領域,它由質量龐大的恒星殆盡後,重力塌縮至無限小的「奇點」(singularity)而成。根據科學家愛因斯坦(Albert Einstein)提出的廣義相對論,它的重力場將強得令任何物質、輻射甚至光線都無法逃逸。

In 1965, when Dr. Hawking was 23, the British mathematician Roger Penrose proved that if Einstein’s theory of gravity, general relativity, was correct there is a point of infinite density — a singularity — at the center of a black hole.
