Human race 'must colonise space or face extinction', warns Stephen Hawking

Stephen Hawking has warned that unless the human race colonises space within two centuries it will disappear forever.

The astrophysicist says that our only chance for long-term survival is to move away from Earth and begin to inhabit far-flung planets.

In an interview with the website Big Think, Professor Hawking said he was an optimist but the next few hundred years had to be negotiated carefully if humans were to survive.


Stephen Hawking has warned that humans will only survive if we leave Earth and venture into space
‘I see great danger for the human race,’ he said. ‘There have been a number of times in the past when survival has been a question of touch and go.

‘The Cuban missile crisis in 1963 is one of these. The frequency of such occasions is likely to increase in the future. We shall need great care and judgment to negotiate them all successfully.


‘But I am an optimist. If we can avoid disaster for the next two centuries our species should be safe as we spread into space.’

Earlier this year, Professor Hawking warned humans should be wary about trying to make contact with other alien life forms as we could not be sure that they would be friendly.

‘If we are the only intelligent dead’beings in the galaxy we should make sure we survive and continue.’

But he warned that mankind was entering an increasingly dangerous period.

‘Our population and use of the finite resources of planet Earth are growing exponentially along with our technical ability to change the environment for good and ill,’ said the author of the bestseller, A Brief History of Time.

‘But our genetic code carries selfish and aggressive instincts that were a survival advantage in the past. It will be difficult enough to avoid disaster in the next 100 years let alone the next thousand or a million.

'Our only chance of long-term survival is not to remain on planet Earth but to spread into space.

‘We have made remarkable progress in the last 100 years but if we want to continue beyond the next 100 years our future is in space.’
Earlier this year, Hawking he said that a spaceship capable of travelling through time - but only forwards - would breach Albert Einstein's theories of relativity.
This means that humans might one day be able to use time travel to skip generations into the future.
Having taken six years to reach its full speed of 98 per cent of the speed of light (650million miles per hour), a day on board the ship would be equivalent to a year on Earth, he said, allowing those on board to reach the edge of the galaxy in just 80 years.

霍金﹕200年內不移民外星 人類將滅亡
http://hk.news.yahoo.com/article/100809/4/jlwe.html
(明報)2010年8月10日 星期二 04:40
【明報專訊】著名物理學家霍金    在接受美國    著名知識分子視頻共用網站BigThink訪談時,再次語出驚人,稱人類如果想繼續存活,需要在200年內移民外星,否則將會滅亡。

指大危機發生頻率將增加

霍金說:「我看到人類的大危機。過去已經有數次人類存亡只是一瞬間的問題。1963年的古巴導彈危機正是其一……這種情况發生的頻率,在未來很可能會增加。我們應該非常小心去作出決定和判斷,令它們迎刃而解……但我也很樂觀。如果我們可以在未來兩個世紀避免災難,我們這物種在散播到太空後應該安全。」

今年較早時,霍金曾警告人類要小心和太空中的外星生物接觸,因為我們不能確定牠們是否友善。他在最新訪談中說:「如果我們是銀河系中的唯一智慧物種,我們要肯定可以生存下去。」他直言,「人類已經步入愈來愈危險的時期……我們的人口以及使用地球有限資源的程度,正隨著我們的科技幾何級數上升,令環境變得愈來愈糟」。

「人類基因中似乎帶有的『自私貪婪』基因,在過去來說,這對生存是優點。但在未來100年要避免災難,都已經非常困難,更遑論是1000或者100萬年……要長遠都可以生存,就不能留在地球,而是擴散到太空去。我們在過去100年作出了值得紀念的進步,但如果我們要在未來100年都繼續,我們的未來就是在太空中。」他表示因此他支持人類太空航行。霍金過去曾稱,相信人類終有一天將可研發出時光機,但時光機只可以往前,不能回到過去。

現有飛行器 赴合適星球需花5萬年

直到目前為止,人類的科技只能發展出以光速千分之一來在太空航行。這代表如果人類使用在阿波羅登月任務中的化學燃料飛行器,前往最近的適宜生活星球,最少要花上5萬年;如果想要在人類壽命期限內移民,我們必須研製出接近光速的飛行器,同時還要保持艙內的人們在飛行過程中能持續抵禦來自外太空的種種輻射    。

霍金:人類必須在100年內 移居另一星球
http://hk.on.cc/int/bkn/cnt/news/20170515/bknint-20170515223229194-0515_17011_001.html

英國著名物理學家霍金曾多次發表對地球毀滅的看法,他將於本年夏季播出的紀錄片《霍金:探索新地球》(Stephen Hawking: Expedition New Earth)中,再次重申預測,指人類必須在100年內離開地球,移居另一個星球,否則將面臨絕種的命運。

霍金稱地球正面對無數威脅,如氣候變化、小行星撞擊、病毒蔓延和人口增加等問題,變得愈來愈危險,而他和團隊正為人類的外太空生活作好準備。他指人類在未來100年,必須移居到另一個星球,否則將會面臨滅亡。霍金此前亦曾指人類將在1千年內會滅絕。

葡萄友:人類壽命由1,000年減到100年 全因以下3大原因
https://hk.style.yahoo.com/%E8%91%A1%E8%90%84%E5%8F%8B%E4%BA%BA%E9%A1%9E%E5%A3%BD%E5%91%BD%E7%94%B11000%E5%B9%B4%E6%B8%9B%E5%88%B0100%E5%B9%B4-%E5%85%A8%E5%9B%A0%E4%BB%A5%E4%B8%8B3%E5%A4%A7%E5%8E%9F%E5%9B%A0-002537777.html

可以話係現世最具影嚮力嘅物理學家霍金,一向都愛發表預測地球命運嘅言論,之前已經有過多番推測,包括人工智能會令人類滅絕、嘗試聯絡外星人會遭遇不幸等,而佢一路以嚟都推算,人類大慨只有1,000年嘅壽命就會終結;不過近霍金最新嘅推論,竟然一下子縮減咗900年,話人類只餘下100年可以生存!

雖然世界上有唔少理論推論人類會滅絕,但畢竟出自物理學大師霍金把口,唔可以完全亂嗡架,根據佢嘅推論,因為以下幾個間題已經急速惡化,導致人類都命不久矣,係咪?快啲睇下啦!不過香港人最關心係,人類末日,咁樓價會唔會跌呀?

溫室效應
導致全球變暖嘅溫室效應可以話係人類滅亡一大原因,溫室效應之下全球海水因冰層融化而不斷上升,據最新美國多間大學推算,2100年時,海平面會上升52至98cm,美國紐約、中國上海等大城市將被淹浸!

小行星撞擊
唔好以為睇戲,其實地球周不時被行星碎片撞擊,而對上一次造成大規模傷亡嘅就係1908年西伯利亞Tunguska隕石撞擊事件。目前最大威脅係一顆由NASA發現嘅小行星,每6年會近距離掠過地球一次,可以話係計時炸彈。

新變種傳染病
講起傳染病大家都唔會陌生,自十多年前嘅SARS開始,一直到禽流感、豬流感、伊波拉等,無一唔係不停變種,而且呢啲新型病毒全部都係死亡率高,致病速度極快,早年已經有英國病毒學家John Oxford警告2017、2018年有機會爆發全球性傳染病。
