Re: [新聞] NASA公布:二十億年前核反應爐照片
看到這種光怪陸離的"新聞"
先看看這則新聞怎麼來的
"明慧網"是什麼東西??!!!http://big5.minghui.org/
這種新聞來源值得相信嗎???
再來做個簡單的查證
google在nasa網站下和gabon nuclear有關的網頁
這是第一個http://antwrp.gsfc.nasa.gov/apod/ap021016.html
裡面不就告訴你是occurred naturally了嗎?!!
怎麼就是有人這麼好騙?!
不過是個花兩分鐘就能釐清的謠言.....
下次這個版又要出現什麼樣的垃圾偽新聞??

: NASA公布:二十億年前核反應爐照片
: 美國航空暨太空總署(NASA)二○○五年二月底公布了在非洲加蓬共和國(Gabon)發現
: 的二十億年前運轉的核反應爐圖片。
: 美國太空總署表示,一九七○年代在非洲發現了二十億年前的核子反應堆(右圖)。圖片
: 顯示的是位於加蓬奧克洛(Oklo)的第十五座反應堆。
: 右圖上明顯的黃色岩石是鈾氧化物的殘餘,淺色條紋是石英,它是反應堆運轉時(或之後
: )地下循環熱水造成的結晶。還有一些穿過岩石的小裂痕和紋理。在使用同位素圖譜技術
: 後發現,這些反應堆在二十億年前就在運轉。
: 事實上《明慧網》於二○○○年三月廿九日就曾報導,二十億年前,在今天的非洲加蓬共
: 和國,曾存在著一個大型的鏈式核反應爐,運轉了數十億年。
: 一九七二年,當加蓬共和國奧克洛礦區的鈾礦石被賣到一家法國的氣體擴散工廠時,法國
: 科學家就發現這些鈾礦含量低於0.711%的自然含量,認為這些鈾礦似乎早已被使用過。
: 當時法國政府宣布這一發現時,震驚了全世界。科學家對這個鈾礦進行了研究,並於一九
: 七五年在國際原子能委員會(International Atomic Energy Agency)會議上發表研究成
: 果。
: P.S.
: 找了一下,NASA的網站也真的有這則照片和新聞:
: http://antwrp.gsfc.nasa.gov/apod/ap021016.html
: Astronomy Picture of the Day
: Discover the cosmos! Each day a different image or photograph of our
: fascinating universe is featured, along with a brief explanation written by a

: Oklo: Ancient African Nuclear Reactors
: Credit & Copyright: Robert D. Loss, WAISRC
: Explanation: The remnants of nuclear reactors nearly two billion years old
: were found in the 1970s in Africa. These reactors are thought to have
: occurred naturally. No natural reactors exist today, as the relative density
: of fissile uranium has now decayed below that needed for a sustainable
: reaction. Pictured above is Fossil Reactor 15, located in Oklo, Gabon.
: Uranium oxide remains are visible as the yellowish rock. Oklo by-products are
: being used today to probe the stability of the fundamental constants over
: cosmological time-scales and to develop more effective means for disposing of
: human-manufactured nuclear waste.
: 我在想會不會是未來人乘時光機到古代做的啊...
: 也只能有這種解釋方法了
