根據(jù)愛因斯坦的理論，我們發(fā)現(xiàn)一個令人吃驚的事實：普通個子的成人的軀體里包含著30顆氫彈的能量。愛因斯坦用一個簡單的公式，一下子使地質(zhì)學(xué)家和天文學(xué)家的視界開闊了幾十億年。該理論尤其表明，光速是不變的，最快的，什么速度也超不過它~~~

文中需聽寫單詞或詞組用[-No-]表示，句子用[---No---]表示。請邊聽寫邊理解文意，這樣可以提高聽力準(zhǔn)確度，并為訓(xùn)練聽譯打下基礎(chǔ)哦~~~
Hints:
lump

supreme
You may not feel outstandingly [-1-] , but if you are an average-sized adult you will contain within your modest frame no less than 7 x 10^18 joules of potential energy—enough to explode with the force of 30 very large hydrogen bombs, [---2---]. Everything has this kind of energy trapped within it. We're just not very good at getting it out. Even a uranium bomb—the most energetic thing we have produced yet—releases less than 1 percent of the energy it could release if only we were more [-3-] .
Among much else, Einstein's theory explained how radiation worked: [---4---] . (It could do it by converting mass to energy extremely efficiently à la E =mc^2.) [---5---] (Ditto.) [-6-] , in a simple formula, Einstein endowed geologists and astronomers [-7-] billions of years. [---8---] Nothing could [-9-] it. It brought light (no pun intended, exactly) [-10-] the nature of the universe. Not incidentally, it also solved the problem of the luminiferous ether by making it clear that it didn't exist. Einstein gave us a universe that didn't need it.

how a lump of uranium could throw out constant streams of high-level energy without melting away like an ice cube
It explained how stars could burn for billions of years without racing through their fuel.

Above all, the special theory showed that the speed of light was constant and supreme.

你或許覺得自己不大健壯，但是，如果你是個普通個子的成人，你那不起眼的軀體里包含著不少于7×10^18焦耳的潛能--爆炸的威力足足抵得上30顆氫彈，要是你知道怎么釋放它，而且確實愿意這么做的話。每種物體內(nèi)部都蘊藏著這樣的能量。我們只是不大善于把它釋放出來而已。連一顆鈾彈--我們迄今為止制造出的能量最大的家伙--釋放出的能量還不足它可以釋放出的能量的1％，要是我們更聰明點的話。
其中，愛因斯坦的理論解釋了放射作用是怎么發(fā)生的：一塊鈾怎么源源不斷地釋放出強輻射能量，而又不像冰塊那樣融化。（只要把質(zhì)量極其有效地轉(zhuǎn)變?yōu)槟芰浚@是辦得到的：E=mc^2。）該理論解釋了恒星為什么可以燃燒幾十億年而又不把燃料用盡。（同上。）愛因斯坦用一個簡單的公式，一下子使地質(zhì)學(xué)家和天文學(xué)家的視界開闊了幾十億年。該理論尤其表明，光速是不變的，最快的，什么速度也超不過它。因此，這使我們一下子弄清了宇宙性質(zhì)的核心。而且，該理論還解決了光以太的問題，說明它并不存在。愛因斯坦的宇宙不需要以太。
