On the basis of these considerations, I believe that life is common on the many planetary systems in the cosmos.
基于這些考慮，我相信，生命普遍存在于宇宙中許多行星系里。
Moreover ,recent discoveries in astronomy prove that if life exists on other planets in the Universe, most of this life is far older than life on the Earth.
再者，天文學(xué)最近的發(fā)現(xiàn)表明：如果宇宙中其他行星上存在生命的話，那么這些生命中的大部分遠(yuǎn)比地球上的生命古老。
The discoveries relate to the so-called Big Bang theory, which holds that the Universe beganwith a gigantic explosion. The Big Bang theory has now been proved to be a fact by the Nobel Prizewinning work of Arno Penzias and Robert Wilson, who discovered the remnant of the primordial flash of light and heat that filled the Universe at the time of the great explosion. In other words, they discovered a relic of events that actually took place shortly after the beginning of the world. Although many astronomers had resisted the Big Bang theory, the Penzias-Wilson discovery has convinced very nearly the last doubting Thomas.
這些發(fā)現(xiàn)同所謂的大爆炸理論有關(guān)。大爆炸理論認(rèn)為宇宙開始于一次巨大的爆炸。大爆炸理論已被諾貝爾獲得者亞諾·彭齊厄斯和羅伯特·威爾遜的研究所證實(shí)，他們發(fā)現(xiàn)了大爆炸時(shí)充滿宇宙的光和熱的最初閃爆的殘余痕跡。也就是說，他們發(fā)現(xiàn)了世界誕生不久后確實(shí)發(fā)生的事件的遺跡。雖然許多天文學(xué)家都曾抵制過這一大爆炸理論，但亞諾·彭齊厄斯和羅伯特·威爾遜的發(fā)現(xiàn)幾乎使每一個(gè)抱懷疑態(tài)度的人都信服了。
The importance of the Big Bang in a discussion of UFOs and life on other worlds is that it tells us when the world began; it tells us the age of the Universe. An astronomer can calculate on the back of an envelope how long ago the Big Bang occurred. That moment marked the birth of the Universe. The result of the calculation is that the Universe came into being 20 billion years ago.
在討論不明飛行物和其他世界的生命時(shí)，大爆炸的重要性在于它能告訴我們世界是何時(shí)開始的，它能告訴我們宇宙的年齡。天文學(xué)家能在一只信封的背面計(jì)算出大爆炸是多少年以前發(fā)生的。那一時(shí)刻標(biāo)志著宇宙的誕生。計(jì)算結(jié)果是宇宙誕生于二百億年之前。
