霍金挑戰上帝:
宇宙渾然天成

著名天體物理學家霍金,挑戰西方國家傳統宗教信仰,指出宇宙並非由上帝所創造,而是根據物理定律而成,可以無中生有,自我創造。

英國報章披露霍金新書《大計劃》的內容,霍金認為新的科學理論顯示,生命完全可以「自然出現」,毋須上帝控制宇宙運作,而宇宙大爆炸是物理法則的必然結果。

God did NOT create the Universe, says Stephen Hawking

Scientist insists Big Bang explained by laws of physics

Britain's most famous scientist has declared God redundant.
In a provocative book, Professor Stephen Hawking said modern physics left no room for a Creator - and that science could explain the origins of the universe.
In The Grand Design, the best-selling author concludes: 'Because there is a law such as gravity, the universe can and will create itself from nothing.
'Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist.

'It is not necessary to invoke God to light the blue touchpaper and set the universe going.'
The book, co-written by American physicist Leonard Mlodinow and published on September 9, sets out to contest Sir Isaac Newton's belief that the universe must have been designed by God as it could not have created out of chaos.

He cites the 1992 discovery of a planet orbiting a star other than our Sun.

'That makes the coincidences of our planetary conditions - the single Sun, the lucky combination of Earth-Sun distance and solar mass - far less remarkable, and far less compelling as evidence that the Earth was carefully designed just to please us human beings.'

Prof Hawking had previously appeared to accept the role of God in the creation of the universe, writing in A Brief History Of Time in 1988: 'If we discover a complete theory, it would be the ultimate triumph of human reason - for then we should know the mind of God.'

He also leaves open the possibility of life on other planets and entire new universes - the so-called 'multiverse'.

Professor Hawking also says that form of complex theoretical physics known as M-theory, a type of string theory, could be the 'holy grail' that will explain everything in the known universe.
Physicists have long sought after a universal theory that unites quantum theory, matter at the sub-atomic level, with gravity which explains how objects interact.
He says: 'M-theory is the unified theory Einstein was hoping to find. The fact that we human beings - who are ourselves mere collections of fundamental particles of nature - have been able to come this close to an understanding of the laws governing us and our universe is a triumph'.
Professor Hawking has been quite outspoken in recent months over a number of issues.

In April documentary series, he argued that it is 'perfectly rational' to assume intelligent life exists elsewhere in the universe.

And in an extraordinary series of assertions, he said Earth might be at risk from what he imagines to be 'massive ships' which could try to colonise our planet and plunder our resources.

Professor Hawking said: 'We only have to look at ourselves to see how intelligent life might develop into something we wouldn’t want to meet.

'I imagine they might exist in massive ships, having used up all the resources from their home planet.

'Such advanced aliens would perhaps become nomads, looking to conquer and colonise whatever planets they can reach.'

It would be 'too risky' to attempt to make contact with alien races, he concluded.

'If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the Native Americans.'
And last month Professor Hawking has warned that unless the human race colonises space within two centuries it will disappear forever.
He said 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.

科學家發現宇宙最古老星系

http://hk.news.yahoo.com/article/110127/8/mfo0.html


(法新社[url=]巴黎
[/url]26日電) 天文學家今天說,他們捕捉到或許是至今所發現最古老的星系照片,這個繁星滿天的星系,早在宇宙嬰兒期就已經形成。
哈伯太空望遠鏡(Hubble)捕捉到132億光年外的微弱光影,意謂這個星系,在開天闢地的「大爆炸」之後約4.8億年誕生。
天文學家說,就算還有更古老星系,也要等到哈伯下一代的望遠鏡啟用後才能觀察到。
加州大學聖克魯斯(Santa Cruz)分校天文學暨天體物理學教授伊靈沃斯(Garth Illingworth)說:「我們非常接近第一批星系,我們認為是在大爆炸後大約2億至3億年形成。」
新發現的星系UDFj-39546824,是在2009和2010年,花了87小時掃描後,才在天際中指甲大小的區塊發現。
伊靈沃斯說:「這個結果是我們能力的極限,不過我們花了好幾個月測試證實,現在相當有信心。」
這個星系雖然古老,不過大小卻遠不如後起之秀,只有我們銀河系的1/100。
這項公佈在[url=]英國
[/url]「自然」(Nature)期刊的研究指出,這些發現顯示大爆炸後的4.8億至6.5億年間,星系歷經巨大轉變,這1億7000萬年間,星星的誕生速度增加了10倍。(譯者:中央社李威翰)1
