Stephen Hawking warns Earth will DIE by 2600

Professor Stephen Hawking has warned mankind will destroy the Earth, turning it into a blazing fireball, within the next 600 years. The renowned physicist believes soaring population sizes and increasing demands for energy will lead to the catastrophe. Humanity should begin looking to the stars to avoid this fate, he argues, with our nearest neighbour Alpha Centauri the best candidate for our escape.

Hawking urged potential financial backers to get behind a project that could one day lead to manned flights to the system. Hawking made the comments while speaking via video link at the Tencent Web Summit, held in Beijing. The British cosmologist, who was diagnosed with motor neuron disease aged 21, is backing the Breakthrough Starshot project.

The Breakthrough Starshot project's ultimate goal is to send a fleet of tiny, light-propelled ‘StarChips’ to our nearest star system, Alpha Centauri. An artist's impression is pictured
It would see a nanocraft probe sent to Alpha Centauri in just over 20 years.   Speaking at the conference, he said: 'The idea behind this innovation is to have the nanocraft on the light beam.  'Such a system could reach Mars in less than an hour, or reach Pluto in days, pass Voyager in under a week and reach Alpha Centauri in just over 20 years.'  The Alpha Centauri star system is 25 trillion miles (4.37 light years) away. 

With today's fastest spacecraft, it would take about 30,000 years to get there. Breakthrough Starshot aims to establish whether a gram-scale nanocraft, on a sail pushed by a light beam, can fly over a thousand times faster.  Astronomers estimate that there is a reasonable chance of an Earth-like planet existing in the 'habitable zones' of Alpha Centauri's three-star system. 
Hawking warned at a seperate conference that AI could be the 'worst thing' for humanity, arguing that mankind needs to put measures in place to prevent robots from taking over

It has been a busy few days for Hawking, with not just one, but two doomsday predictions for the future of the planet. Humanity must also be prepared to tackle artificial intelligence to stop robots replacing people, he warned at the 2017 Web Summit, held in Lisbon and attended by around 60,000 people.

Hawking said the technology could transform every aspect of life but cautioned that intelligent machines pose new challenges. 

He said robots are already threatening millions of jobs but that this new revolution could be used to help society and for the good of the world, including alleviating poverty and disease.

'The rise of AI could be the worst or the best thing that has happened for humanity,' Hawking said via video link at the opening night of the summit on Monday. We simply need to be aware of the dangers, identify them, employ the best possible practice and management and prepare for its consequences well in advance.'

Hawking's comments come during an escalating debate about the pro and cons of AI, a term used to describe machines with a computer code that learns as it goes. Silicon Valley entrepreneur Elon Musk, who is chief executive of electric car maker Tesla Inc and rocket company SpaceX, has warned that AI is a threat to humankind's existence.

But Microsoft co-founder Bill Gates, in a rare interview recently, told the Wall Street Journal that there was nothing to panic about. Hawking said everyone has a role to play in making sure that this generation and the next are fully engaged with the study of science at an early level. He hope that this will create 'a better world for the whole human race'.

'We need to take learning beyond a theoretical discussion of how AI should be, and take action to make sure we plan for how it can be,' said Hawking, who communicates via a cheek muscle linked to a sensor and computerised voice system.

'You all have the potential to push the boundaries of what is accepted, or expected, and to think big. We stand on the threshold of a brave new world. It is an exciting, if precarious, place to be and you are the pioneers,' he added.


  1. Stephen Hawking hasn't taken account of the fact that our exponential growth has stopped. The same number of children were born in 2005 as in 2017 and our population is currently growing due to increasing lifespans, not through exponential growth. The middle of the range estimate is for it to level off at around 11 billion by 2100.

  2. You know, this guy is turning into a real downer and curmudgeon in his old age. Practically every time he speaks now, it is negative and depressing.
    He says E.T. will kill us if we make contact, the world is ending etc. Perhaps he should get up of his ass and wonder around town wearing one of those, “The End Is Near!” signs.

  3. you people are in the dark ages. technology is stopping for nothing. look whats happened in ten years or fifty years. your lifetime will see AI and you will not be able to stop it. look again at the past and i hope you will see into the future
