As part of a new documentary to be released on the BBC next September, physicist, theorist and cosmologist Stephen Hawking says there is only one century left for mankind to escape extinction. 

A century to leave the Earth and find a viable existence in another planet. Stephen Hawking believes that this is the challenge facing humans. 

The astrophysicist said in a documentary made for the BBC television station that we had only a hundred years left before the human race disappeared forever from the surface of the Earth, reports the Telegraph, Tuesday 2 may. Hence the solutions?

In a year, things would have worsened to the point of accelerating the extinction of man on Earth? 

Whether it is a simple com to promote this new documentary or a sincere prediction, the problem is posed: it will be necessary to find a habitable shelter in case humanity is really destined to have to leave the Earth. 

The planet Mars, which Elon Musk wants to conquer from 2018, is emerging as the first of the alternatives. Yet life on the red planet could prove very harmful. 

The radioactive particles in its atmosphere would produce irreversible sequelae on the human brain. 

Not to mention its soil with toxic substances, its freezing temperatures and its unbreathable air. 

So of course, some will argue that it is possible to terraform Mars to make it a truly habitable planet, but it would take hundreds of thousands of years, Popular Science points out. 

Perhaps the ideal would be to begin exploring beyond our solar system in the hope of finding some of the 100 billion planets of the Milky Way a little water, land, Breathing air. Otherwise, one can always remain pragmatic and prefer to flee ahead to new horizons, reflection on our modes of production and consumption. 

If they remain unchanged, they will continue to destroy the environment, on Mars, as on any other planet. 

They will go to explore other parts of the universe in the hope of finding refuge there. 

Entitled "Expedition New Earth," the documentary was produced to celebrate the return of the BBC's flagship futuristic series Tomorrow's World, after 38 years of absence. 

It is expected to be released next September, the BBC said. 

Stephen Hawking, a proponent of apocalyptic predictions, however, spoke last year on a longer deadline: 

"Although the risk of catastrophe that weighs on the planet in a given year seems low, it adds up over time and will become almost certain In 1,000 or 10,000 years, "he told a conference at Oxford University last November.
