PTE Re-tell Lecture 真实讲座练习题:普朗克比例

在PTE中,无论是Summarise Spoken Text 还是 Re-tell Lecture的考题大都是从真实的讲座或者演讲中截取的,中间经常经常夹杂很多不同的环境音.很多同学都反映有时未必是听不懂,而是听不到. 鉴于此,墨尔本文波雅思PTE专门为大家总结了真实讲座的PTE练习音频,相比新闻音频来说,整体更加接近PTE考试的真题,内容方面,我们也会为大家提供考试中存在的近似题,最近我们会持续更新,敬请期待!

The Planck scale is such a tiny number that it is hard to wrap your mind around how small it is. But in the analogy, you cannot help, if you were to take say an atom and magnify that atom to be as big as the size of the observable universe, that’s a huge scale of magnification. Then under that same scale of magnification that the Planck Scale will turn into the roughly the size of an average tree. So a tree is the observable universe as the Planck Scale is to an atom. That‘’s how small it is. That’s why so challenging to observe any of the physical phenomena that we think may be taking place at the Planck Scale, it’s just so fantastically small.
