To understand this mind-boggling idea,
為了了解這個讓人一頭霧水的觀點
consider one of these a black hole floating in space.
想象一下有個黑洞 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過巨大
that it has collapsed in on itself.
以致于往內塌陷
It's so massive that not even light can escape its gravity,
巨大到就連光線也逃不過其引力
which is why it's almost perfectly black.
所以它才會是近乎漆黑
Its gravitational field is so powerful,
它的重力場如此強大
it doesn't only warp and distort light but also time.
不僅能使光線扭曲變形 甚至時間也逃不過
To see how,imagine a clock is being sucked into it.
你不妨想象 成有個時鐘被吸進去
As the clock gets closer and closer to the black hole,
隨著時鐘越來越接近黑洞
it begins to get slower and slower.Time itself begins to slow down.
它開始走得越來越慢 時間慢了下來
Now imagine the clock as it enters the black hole.
現在想象時鐘進入黑洞
Well,assuming,of course,it could withstand the extreme gravitational forces,
當然這是要假定 它能承受極為龐大的重力
the clock would actually stop.
時鐘會就此停止
