BBC: Stephen Hawking warns humanity has just 200 years to escape Earth

Stephen Hawking warns humanity has just 200 years to escape Earth and says Donald Trump has taken ‘the most serious, and wrong, decision on climate change this world has seen’

Professor Hawking believes life on Earth is at high risk of being wiped out. Future generations must forge a new life in space if we want to survive. He also accused Donald Trump of taking ‘the most serious, and wrong, decision on climate change this world has seen’ – Report from Daily Mail

Humans must find a new home in space in the next 200 to 500 years if we are to survive, Professor Stephen Hawking has warned.

The physicist repeated his warning that the human race is doomed at the Starmus Festival celebrating science and the arts, which is being held in Trondheim, Norway.

He also slammed US President Donald Trump, saying ‘I am not denying the importance of fighting climate change and global warming, unlike Donald Trump, who may just have taken the most serious, and wrong, decision on climate change this world has seen,’ he said.

Hawking called for leading nations to send astronauts to the Moon by 2020 in a bid to re-ignite space exploration.

They should also aim to build a lunar base in 30 years’ time and send people to Mars by 2025, he said, according to the BBC.

‘Spreading out into space will completely change the future of humanity,’ he said.

‘I hope it would unite competitive nations in a single goal, to face the common challenge for us all.

‘A new and ambitious space programme would excite (young people), and stimulate interest in other areas, such as astrophysics and cosmology’.

He revealed his hope nuclear fusion-powered ships propelled by light or another energy form will guide us to our new home.

‘The Earth is under threat from so many areas that it is difficult for me to be positive,’ he admitted.

‘The threats are too big and too numerous.

‘Our physical resources are being drained, at an alarming rate. We have given our planet the disastrous gift of climate change.

‘Rising temperatures, reduction of the polar ice caps, deforestation, and decimation of animal species. We can be an ignorant, unthinking lot.’

Professor Hawking is working with  Russian billionaire Yuri Milner’s Breakthrough Starshot project to send a fleet of tiny ‘nanocraft’ carrying light sails on a four light-year journey to Alpha Centauri, the nearest star system to Earth.

‘If we succeed we will send a probe to Alpha Centauri within the lifetime of some of you alive today,’ he said.

‘It is clear we are entering a new space age. We are standing at the threshold of a new era. Human colonisation and other planets is no longer science fiction, it can be science fact.’

The camera-equipped miniature probes, would be sent on their way by tens of gigawatts of focused power from an array of lasers, reaching their destination in about 20 years.

He said doing nothing and acting as ‘cosmic sloths’ was not an option.

‘When we have reached similar crises in our history, there has usually been somewhere else to colonise. Columbus did it in 1492 when he discovered the New World. But now there is no new world. No Utopia around the corner.

‘We are running out of space and the only places to go to are other worlds.
