In fact in 1972, I wrote a paper on this subject with Brandon Carter and an American colleague Jim Bardeen. We pointed out that, although there were many similarities between entropy and
38、 the area of the event horizon, there was this apparently fatal difficulty. I must admit that in writing this paper I was motivated partly by irritation with Beckenstein, because I felt he had misused my discovery of the increase of the area of the event horizon.

Thats when I turned the world upside down, at least for scientists, with several new ideas. I proposed that space and time had to be looked at in a whole new way that Newtons view of spa
43、ce and time was inaccurate. These ideas became known as the special theory of relativity and introduced the equation E=mc2. Ten years later I presented the general theory of relativity. The general theory showed that gravity is not a force, as Newton had thought. It is instead a curvature (曲率曲率) of
