After the recent warning to the world against contacting aliens, renowned physicist Stephen Hawking has once again gave a strong statement that the human race is going to be doomed unless we move to space.

Hawking, who had previously issued warnings about robots wiping out humanity, had been warned that the threat of war and/or disease looms large over our home planet Earth and humanity has better chances of surviving if the giant shift to space is made.

This warning has come through by way of a new book, 'How to Make a Spaceship', written by journalist Julian Guthrie, which contains an afterword by the physicist.

He said, 'I believe that life on Earth is at an ever-increasing risk of being wiped out by a disaster, such as a sudden nuclear war, a genetically engineered virus, or other dangers'.

The Daily Mail reported, that the scientist said, “I think the human race has no future if it doesn't go to space,”.

The 74 years old scientist, further stated that the threats included nuclear war, catastrophic global warming and genetically engineered viruses.

The Daily Mail also quoted that, 'We are not going to stop making progress, or reverse it, so we must recognise the dangers and control them.'

To get away from these threats, humankind will have to colonise other planets, which according to Hawking will take more than a century.

Hawking said, 'We will not establish self-sustaining colonies in space for at least the next hundred years, so we have to be very careful in this period'.
