6億人一起跳地球@7/20日19時39分13秒

德國藝術家勞希曼2005年成立「跳地球」網站,發起「跳地球日」 (World Jump Day),號召西半球民眾2006年7月20日格林威治11時39分13秒(台北時間7月20日19時39分13秒)一齊往空中一跳,說只要有六億人同時這麼一跳,將能改變地球在宇宙裡的位置,亦即使地球改變軌道,離開太陽一點,從而「停止全球暖化、延長白天時數,創造更適合人居的氣候」。

勞希曼當初向科學家和部落格提出「跳地球日」,只當朋友圈裡說說,結果消息傳開,變成全球話題,好奇、好玩、好事的人紛紛上網,網站擠爆好幾次。齊跳日轉眼就到,據7月18日統計,已達598,104,080人登記參加,已近全球上網人數的一半。該網站聲稱20日達到六億人沒問題。

六億人同步一跳,把地球跩離軌道,屬於一種「地球工程」(geoengineering),用意不錯,但問題很多,難以當真。從道德層面看,誰能承擔地球軌道改變的後果?有人說,地球走上新軌道,日曆不是要改寫嗎?也有人說,誰能保證這麼多人真的同一秒起跳?

但真正的問題是,這麼一跳真的有用嗎?根據專門討論怪點子的「瘋狂物理學」網站 (madphysics.com),假定每人體重一百公斤,六億人就是將10先11平方,再乘6,他們齊跳產生的動能相當於7.5兆焦耳 (TJ),等於一百萬噸黃色炸藥(相當於一枚現代氫彈)所釋能量的2%,造成的地球移位只有一個氫原子半徑,亦即地球軌道不變。

英國廣播公司 (BBC)報導,科學家計算,地球再遠離太陽2.4公里,就能抵消大氣裡二氧化碳增加兩倍之害,但這需要用數百萬枚氫彈來炸地球。到時地球還在嗎?

人定勝天的想法自古從沒斷過,例如人類從來就想控制或改變氣候,用溫室廢氣把生活環境搞砸後,此念益切。救地球有治本,有治標,治本是迅速減少或根本停止排放溫室廢氣,看目前人類的表現,大不易。

治標即「地球工程」,例如取法火山爆發,把無數硫化小球(sulphur pellet)射到空中,增加把太陽光擋回去的反射力,但硫化物會破壞臭氧層,暖化問題解決,人類也死光了。

美國國家科學院知道,讓5萬5000面鏡子進入軌道,把太陽光反射掉,能抵消二氧化碳加倍的效應,但每鏡子必須有一百平方公里大,不可行。看來,「地球工程」說易行難,還是想法治本吧。

you feel like












You feel like you are putting on a mask
where you dont even know who you are
you feel like you are lying to yourself
and everyone else that you cared the most
you feel like what you beliveded in
has shattered into unsignificant pieces of information
that you dont even understnad what they mean
you feel like you are the darkest star among the universe
that nobody sees and nobody can touched upon
you feel like you are hopelessly yelling out for help but
all what you can do is remain stiff with ur heart, your body and remain silent
you feel like you are holding back all the things you really feel
and all the things you really want to say because you are afraid of facing the truth
you feel like you are going back to where you were before
the total emptiness and the total disaster
you feel like the nights have swallow you , eaten you alive
and hitting right at you to tell the truth
you feel like being teared apart as if you are not who you are,
double personalised life one for the day one for the night

you feel like you dont know what to feel where to go when to stop how to begin and you feel like
you just want to be able to tuck in the bed and sleep peacefully for the rest of your life.
