《異種》成真　地球發現外星人散布的生命種子

▲溫韋萊特團隊發現的金屬小球，裡面還有一些黏性的生物物質從裡面滲出來。(圖／翻攝自天文學期刊)國際中心／綜合報導英國科學家仔細檢視過一個小小的金屬圓形物體後，宣稱它可能是外星人故意送到地球來繁洐生命的微生物。科學家說，大家不要被顯微鏡把它放大後的體積所蒙騙了，這個看起來像一顆行星大小的球體，直徑比不上人類頭髮的寬度。英國白金漢大學(University of Buckingham)發表報告說，這個微小的金屬球體，是天體生物學家溫韋萊特(Milton Wainwright)和他的團隊利用高空氣球在地球平流層收集宇宙塵埃後從中發現的。溫韋萊特告訴《快報》網站(Express.co.uk.)說：「這個球體的直徑跟人類頭髮的寬度差不多，球體外發現一些絲狀生物，還有一些黏性的生物物質從裡面滲出來。」通過顯微鏡觀察發現，這個球體並沒有一般隕石撞擊形成的痕跡，它們可能是輕輕的落到地球來。溫韋萊特提出假設說：「一些未知的外星文明把它們送到地球來，是為了在地球播下生命的種子。」上述理論來自一名諾貝爾獎得主的學說。溫韋萊特教說：「這種小球可能來自某個外星文明，它們被宇宙射線或流星帶到地球。這種聽起來像是科幻小說的理論，稱作『定向泛種論』(Directed panspermia)，若非發現DNA雙螺旋結構的美國分子生物學家克里克(Francis Crick也提出過這套理論，可能不會有任何嚴肅的科學家會非常認真地的看待這種說法。」「定向泛種論」的理論是：地球上生命的種子來自宇宙。生命透過在彗星或隕石上「搭便車」的方式，在整個已知的宇宙中散播。支持者認為，要讓科學界接受這套理論還有很長的一段路要走。溫韋萊特說：「儘管距離科學界認可我們的研究成果仍需一些時日，但我們還會繼續研究，希望在未來能找出到底是哪個外星文明向地球傳送了這些球形的微生物。原文請看這裡相關報導及更多照片請看這裡http://www.dailymail.co.uk/sciencetech/article-2955620/Did-aliens-send-metal-orb-seed-life-Earth-Microscopic-sphere-contain-microorganisms-claims-astrobiologist.htmlhttp://www.huffingtonpost.com/2015/02/03/aliens-send-space-seed-to-earth_n_6608582.html?utm_hp_ref=mostpopularUK Scientists: Aliens May Have Sent Space Seeds To Create Life On EarthThe Huffington Post | ByLee SpeigelEmailPosted:02/13/2015 8:12 am ESTUpdated:02/13/2015 9:59 am EST

Scientists in the U.K. have examined a tiny metal circular object, and are suggesting it might be a micro-organism deliberately sent by extraterrestrials to create life on Earth.Don"t be fooled by the size of the object in the microscopic image above. It may appear to look like a planet-sized globe, but in fact, it"s no bigger than the width of a human hair.TheUniversity of Buckingham reportsthat the minuscule metal globe was discovered by astrobiologistMilton Wainwrightand a team of researchers who examined dust and minute matter gathered by a high-flying balloon in Earth"s stratosphere."It is a ball about the width of a human hair, which has filamentous life on the outside anda gooey biological material oozing from its centre," Wainwright said, according toExpress.co.uk."One theory is it was sent to Earth by some unknown civilization in order to continue seeding the planet with life," Wainwright hypothesizes.That theory comes from a Nobel Prize winner."This seeming piece of science fiction -- called "directed panspermia" -- would probably not be taken seriously by any scientist were it not for the fact that it was very seriously suggested by theNobel Prize winner of DNA fame, Francis Crick," said Wainwright.Panspermia is a theory that suggests life spreads across the known physical universe, hitchhiking on comets or meteorites.The idea of directed panspermia was suggested by Crick, a molecular biologist, who was the co-discoverer of the structure of DNA in 1953. Twenty years later, Crick co-wrote -- with biochemist Leslie Orgel --a scientific paperabout directed panspermia.The abstract of their manuscript states:It now seems unlikely that extraterrestrial living organisms could have reached the Earth either as spores driven by the radiation pressure from another star or as living organisms imbedded in a meteorite. As an alternative to these nineteenth-century mechanisms, we have considered Directed Panspermia, the theory that organisms were deliberately transmitted to the Earth by intelligent beings on another planet.We conclude that it is possible that life reached the Earth in this way, but that the scientific evidence is inadequate at the present time to say anything about the probability. We draw attention to the kinds of evidence that might throw additional light on the topic.In contrast to what Crick-Orgel speculated about in 1973, four decades later, a team of scientists, led by astronomer-astrobiologist Chandra Wickramasinghe of the Buckingham Center for Astrobiology, announced they had foundfossils with biological propertiesattached to a meteorite (check out the slideshow at the bottom of this story) that fell in Sri Lanka.Of course, these controversial claims bring forth the skeptical side of science.In the case of the meteorite fossils, astronomerPhil Plaitwrote that the scientists didn"t do a good enough job convincing him there were actual fossils in that meteorite.Wainwright and his team launched balloons nearly 17 miles into Earth"s stratosphere, and when they examined the material collected by one of the balloons (like the one pictured below), they discovered a small crash mark which indicated to them that the microscopic, circular object didn"t simply land softly."On hitting the stratosphere sampler, the sphere made an impact crater, a minute version of the huge impact crater on Earth caused by the asteroid said to have killed off the dinosaurs," Wainwright said.

Even with this more recent discovery of a tiny globe found lodged into a high-flying balloon, the alien space seed proponents know they have a long way to go before that can be proven and accepted by the scientific community."Unless, of course, we can find details of the civilization that is supposed to have sent it in this respect, it is probably an unprovable theory," Wainwright conceded.Time -- and space -- will tell.ALSO ON HUFFPOST:CloseScientists Claim ET Fossils In Meteorite1of8
