Stephen Hawking issues warning again - Future of human race in grave danger unless we move to space!

New Delhi: After recently meting out a warning to the world against contacting aliens, renowned physicist Stephen Hawking has once again made a strong statement saying that the human race is destined to be doomed unless we move to space.

Hawking, who has previously issued warnings about robots wiping out humanity, has 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.

'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,' he said.

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

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

The Daily Mail also quoted him saying 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 Hawking believes will take more than a century.

'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,' Hawking said.
