第一篇：Englis_外星人存在的可能性演讲稿

In the universe, are we alone, or is there life out there in space?

Background:

On December 2, 2010, the NSAN(美国国家航天航天局)held a conference and

issued the latest findings of cosmobiology(宇宙生物学)which had a major influence on extraterrestrial life.When the news was released, the hearsay on the internet said that the United States announced they discovered the alien.But most of the media did very peacefully.Do the alien or extraterrestrial lives really exist in our universe?

I think so!

The first reason is the extremophile [ik'stri:məfail](嗜极生物).And what is the extremophile? Generally speaking, the extremophile is a kind of creature who can grow and breed in “extreme” environment.You may be confused what does the relationship between the extraterrestrial life and the extremophile.Let me explain it for you.The reason why we don’t believe extraterrestrial life exist is we know the environment in the other planets is very hard and it does not suitable for biology.There are many places in our planet whose environment is very likely to the other planets, and we find creatures , who are extremophile , on those places.Since these creatures can live in this kind of environment, we have the reason to believe that these creatures also can live in other planet.Let us to know an invertebrate(无脊椎动物)named water bear(水熊虫), then you will know how strong life is.The European Space Agency(欧洲太空总署)took some water bears to the space using satellite, exposed them to the space environment, let them without air and took 1000 times the radiation of other creatures on the ground.The water bears suspended their all life activates in the extreme space environment.But when the satellite back on earth, the researchers examined the water bear and the result showed that most of them were survived.I think if we throw some water bears to the Mars, millions years later we may harvest Martians.These are just some hypothesis, but some proof real exist.The proof is Martian meteorite “AllenContinuously Habitable Zone(CHZ)or ”ecoshell“(Astronomy, Planetary Evolution, Chemical and Biological Evolution)

Ne = Number of planets in the CHZ(Astronomy, Planetary Evolution, Chemical and Biological Evolution)

PL = Probability that life will arise in the CHZ(Chemical and Biological Evolution)PI = Probability that the life will develop an ”intelligent“ civilization(Chemical and Biological Evolution)

Lic = Lifetime of intelligent civilization(Speculative Sociology)

The Milky Way Galaxy contains some 250 billion stars, and even with a million civilizations, less than one star in 200000 would have a planet inhabited by an advanced civilization.The Milky Way is just one of billions of galaxies in the observable universe.Considering the whole universe there will be more planets which have high civilization.they are so far away from us that we can't contact with them.If the UFO is really a ride with aliens and aliens really come to Earth, why they don't contact with us? This question is easy to answer.Well, the first thing if they are too big or too small, they can't communicate with us.can we communicate with bacteria?

The second thing thinking about how we observe animals, you will know why they don't contact with us and why we can't find them.So don't bully people around you.they may be aliens.”Aliens may exist but mankind should avoid contact with them as the consequences could be devastating" Stephen Hawking said.Thinking of how European settlers did with American Indians after Columbus discovered new lands, you will agree with Hawking.

Do you like aliens? You maybe say yes.However, I don't want to see them!Then let me tell you the reason for that.Actually, there're many on our Earth.However there are few people can see them.Luckily, I am one of those who can see the aliens clearly.Last week, I made a joke on a little alien.I kicked a football and it hit the alien.I ran away quickly and laughed aloud.The little alien is too young.So he always wants to make a joke on me, but I never give him a chance.Unluckily, yesterday he met me in English class.I saw him go straight to our English teacher, then he put a figure on sir's head.There will be something terrible happening on me, I thought.Right on cruel sure enough,“THE MONITOR!”The monitor couldn't answer the question.I knew it was my turn “THE pARTNER!”Oh, my god!My English is so poor.How can I answer this question? Suddenly, I saw the little alien.He laughed happily.I regretted making the joke on him.I don't want to see aliens again!

第四篇：存在演讲稿

存在演讲稿

在中国人的宇宙观里，宇是时间，宙是空间，在辽阔的时空交错中，看见了古今未来。无论我们是否思宇宙，是否谈宇宙，我们都是宇宙的一部分。用亚里士多德的话说，这是“思想思想”。我们用来思想思想的能力，即我们用来思想的能力，实质上是同一种能力。如果我们怀疑我们思想人生，思想宇宙的能力，那我们同样也有理由怀疑我们思想思想的能力。所以，宇宙是一切存在之全。

在斯宾诺莎主义里，存在即上帝。爱人，是道德价值，爱上帝，是超道德价值。而在中国，存在即精神，提高心灵的境界达到超越现世的境界，得到高于道德价值的价值。先为学，后为道。所以在我们自己的多元宇宙里，往往是接近现世的。

然而，思想家罗素提出过一个问题，“你怎么证明世界不是在五分钟前被创造出来的？”也许我们觉得一张几小时前的购物单，一本几天前买的书，或者我们记得做过什么事，认识过什么人。但是，记忆也是可以随着世界创造而被创造出来的。你怎么证明自己的记忆都是真的？传统哲学里认为物质不以意志为转移，但是量子中却存在一种粒子它的运动轨迹由观测结果决定。眼见未必为实，耳听也未必为虚。薛定锷的猫在原子瓶中，你却不能回答它现在是否活着这个问题。我们生从何来？去往何处？庄周吾梦也的回答洞穿了一切。看似荒谬的答案解决了一切问题。浮生若梦，因为若，所以存在了选择的可能。你可以觉得浮生是梦，也可以觉得一切无比真实。所以存在与否，也存在了不确定的确定性。

既然存在，在时代发展过程中就一定存在各种各样的问题。综合起来的精神高点就是两难结构。两难之所以难，就是因为两方面都具有一定的合理性。这就像黑格尔所说的，真正的悲剧不是出现在善恶之间，而是出现在两难之间。后来萨特的存在主义中的选择学说，与这有很多相似之处。不过黑格尔表现出一种深刻的无奈，而萨特则表现出一种洞悉生存秘密后的主动。然而，天下的事情未必都能像萨特说的那样具有主动选择的能力。比如清末的一些学者们，很多选择不能由他们自己做出，只能在别人选择的夹缝中做一些自己力所能及的事情。

我们何其幸运，拥有自己选择的能力，自己的命运掌握在自己手里。我们可以选择自己想做的事情，可以选择自己想要的未来。但是这些选择都是建立在一定的基础之上的。我们要先学会选择怎样活在当下，不是虚度年岁在原地守株待兔，也不是一味务实闭门书斋。有一句话说“书斋里的思考往往在现实中以反讽的方式实现。”所以我们既要安于内，也要观于外。这就像从象牙塔到十字街头，存在的多元性在这里得到体现。象牙塔的高度并不能俯瞰一切，十字街头的喧扰也不一定就没有真理。在这个过程中，有些人会随波逐流，有些人会发生变化，但也有些人会固守本真。社会的发展往往不是由喧扰的人群决定的，而是十字街头的少数坚持原则的人主导的。

有人说，书读得越多，经历的越多，往往会看到更多的阴暗面。但是我却相信存在。物质双方都是可以转化的，不美好的一面越多，说明美好的一面越多。看不到不代表不存在，就像不成功并不代表不可能。

第五篇：爱因斯坦能量守恒定律被指证明鬼魂存在可能性

爱因斯坦能量守恒定律被指证明鬼魂存在可能性

据美国《生活科学》（livescience）网站11月9日报道，近期网络上涌现出了大量文章，重申爱因斯坦的能量守恒定律证明了鬼魂存在的可能性。著名搜索引擎谷歌的统计数据显示，该网站上相关搜索词条竟然多达近800万条。不过，科学家称上述观点纯属无稽之谈。

爱因斯坦的能量守恒定律表明，能量是守恒的，既不能被创造也不能被消灭。该言论的支持者们认为，如果上述定律被视为现代物理学的永恒真理，那么人类体内的能量在肉体死亡后就不应该随即消失，而是会转变成另一种存在形式即鬼魂。信奉这一观点的“抓鬼”爱好者经常会在深夜携带着各类电磁场探测设备前往废弃的仓库、楼房或墓地去追踪鬼魂出现的迹象。

同意上述观点的人中，也不乏专业人士。鬼魂研究专家约翰·卡丘巴就是其中的一员。他曾在自己2007年出版的专著《幽灵猎人》一书中探讨过能量守恒定律与鬼魂存在性之间存在必然关联这一问题。

然而，科学家指出，只要用最基础的科学理论来分析一下，就知道这种言论纯属无稽之谈。实际上，人类体内的能量在肉体死亡之后会与其他有机生物一样回归到自然环境中。如果遗体被埋葬，那么人体内的能量就会被植物、昆虫或土壤中的细菌分解吸收；如果遗体没有被埋葬，那么这些能量会被分食遗体的野生动物吸收转化；如果遗体是被火葬的，那么能量则会以热能和光能的形式消散到空中。

这个过程说起来其实非常简单，与人类吸收和代谢动植物中的能量是一个道理。这些食物通过人体消化代谢系统的化学反应生产出人类生存和再生产所需的能量和热量，而不会转化成另外一种存在模式。

有些“抓鬼”爱好者还声称自己携带的电磁场探测仪器能够检测到“鬼魂”散发出的电场。但科学家指出，虽然人类和其他有机生物在代谢过程中会散发出微弱的电流，但是肉体一旦死亡，这一现象就会自然停止，因为电流的“源头”已经停滞了工作。这与切断了电源开关之后灯泡就无法再被点亮是一样的。
