  But we apply those equations to the far end of the galaxy,
  但我们那些式子在银河系的尽头
• 
  
  the far end of the universe,
  宇宙的边际 久远至大爆炸
• 
  
  and going all the way back to the Big Bang.
  竟然都适用
• 
  
  And we predict the future fate of the universe.
  还能预见宇宙的将来
• 
  
  So, we assume that the laws that we discover here,
  我们假定此时此刻发现的定律
• 
  
  now, are valid everywhere and at all times.
  何时何地都适用
• 
  
  So far that seems to be true,
  至今看来这都是正确的
• 
  
  and that's a big break for us.
  对于我们而言是巨大的成功
• 
  
  But for that you really couldn't do anything,
  但如果你今天发现的定律明天就失效了
• 
  
  if the laws you discovered today are not valid tomorrow,
  不能用预言任何东西
• 
  
  you cannot make any predictions.
  对你就毫无意义
• 
  
  So, it's another unwritten benefit we got unspoken
  所以这就是发现一条普适定律
