To understand this mind-boggling idea,
为了了解这个让人一头雾水的观点
consider one of these a black hole floating in space.
想象一下有个黑洞 漂浮在宇宙中
A typical black hole is a star so massive
典型黑洞的形成是有恒星太过巨大
that it has collapsed in on itself.
以致于往内塌陷
It's so massive that not even light can escape its gravity,
巨大到就连光线也逃不过其引力
which is why it's almost perfectly black.
所以它才会是近乎漆黑
Its gravitational field is so powerful,
它的重力场如此强大
it doesn't only warp and distort light but also time.
不仅能使光线扭曲变形 甚至时间也逃不过
To see how,imagine a clock is being sucked into it.
你不妨想象 成有个时钟被吸进去
As the clock gets closer and closer to the black hole,
随着时钟越来越接近黑洞
it begins to get slower and slower.Time itself begins to slow down.
它开始走得越来越慢 时间慢了下来
Now imagine the clock as it enters the black hole.
现在想象时钟进入黑洞
Well,assuming,of course,it could withstand the extreme gravitational forces,
当然这是要假定 它能承受极为庞大的重力
the clock would actually stop.
时钟会就此停止
