[請益] 粒子&反粒子,看過DISCOVERY的"史蒂芬霍金看宇宙"請進
最近看到DISCOVERY的"史蒂芬霍金看宇宙:時間簡史過去篇"時
他提到了粒子與反粒子在宇宙中的出現
在太空任何地方,都會有粒子(正質量)與反粒子(負質量)成對出現
其同時出現,存在不到十億分之一秒後,並又同時消逝,如下:
(○反粒子,●粒子)
nothing.....
↓
←○●→
↓
←○ ●→
↓
○ ●
↓
○→←●
↓
○●
↓
nothing.....
然後,他說如果這樣的情形發生在黑洞附近的話,就會變成:
(◎黑洞,○反粒子,●粒子)
◎ nothing.....
↓
◎ ←○●→
↓
◎ ←○ ●→
↓
◎←○ ●→
↓
◎○ ●→
↓
◎ ●→
所以他的結論說,黑洞附近會有輻射產生,科學家也證明他的想法是對的
不過我想問的是,為什麼不會有下面這種情形發生呢?
◎ nothing.....
↓
←○●→
◎
←●○→
↓
←○ ●→
◎
←● ○→
↓
←○ ●→
◎
←● ○→
↓
●┐
○ ↓
◎
● ↑
○┘
↓
◎ nothing.....
我的意思就是,成對產生的粒子,會跟其他成對產生的粒子抵銷,為什麼不會這樣呢?
這裡有個影片類似我要問的東西:http://www.youtube.com/watch?v=xvq6uZf-Nck
圖真難畫阿......不知道有沒有人能理解我要問的東西(= =|||)
