Technology must be controlled to protect the future of mankind, Stephen Hawking has warned.
The physicist, who has expressed about the dangers of artificial intelligence in the past, said a "World Government" could be our only hope.
He says that our "logic and reason" might be the only way to defeat the growing threat of nuclear or biological war.
We are living through the most dangerous time in the history of the human race, according to Professor Stephen Hawking. The Cambridge University physics professor named overpopulation, climate change and diseases as just some of the threats facing our planet
Since the beginning of civilization, aggression has been helpful insofar as it has advantages of final survival,"he told the Times.
"It is hardwired into our genes by Darwinian evolution.
"Now, however, technology has progressed at a pace that this attack can destroy us all by a nuclear or biological war. We must control this hereditary instinct by our logic and reason.
He suggests that 'a form of world government' could be ideal for work, but itself would create more problems.
"But that could become a tyranny," he added.
"All this may seem a bit loaded of doom, but I am optimistic. I think the human race will rise to these challenges.
Recently, the University of Cambridge physical teacher named overpopulation, climate change and diseases such as some of the threats to our planet.
He said, we have developed a technology that could destroy the Earth, and we need to "recycle" for a new world where robots have replaced many jobs every day.
Wrote in a commentary article in The Guardian, Professor Hawking explained what he worried about the future of our planet.
"For me, the appearance really about what is now, more than at any time in our history, our species needs to work together," he said.
"We are facing great environmental challenges: climate change, food production, the overcrowding, the decimation of other species, the epidemic disease, the acidification of the Oceans."
Professor Hawking said 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
Together, they remind us that we are the most dangerous time in the development of humanity.
"We now have the technology to destroy the planet on which we live,but have not yet acquired the ability to escape."
"Perhaps a few hundred years, we will have human colonies established in the middle of the stars, but now we only have one planet, andwe must work together so to protect."
The world-renowned physicist has already issued warnings to the world that robots could annihilate mankind and who leaves the Earth isour only hope and that our days on earth are numbered.
In September, the physicist warned that our planet is becoming a dangerous place because of the threat of war or disease.
"I believe that life on Earth is a growing risk to be wiped out by a disaster, such as sudden nuclear war, a genetically engineered virus or other dangers," he said.
I think that the human race has no future if she does not go to space.
Professor Hawking held similar remarks earlier this year during the annual Reith Lectures for the BBC recording on January 7.
The Conference explored research into black holes, and his caveat was conducted during questions commissioned by members of the audience.
When asked how the world will end, Hawking said that increasingly,most of the mankind faces threats come from advances in technology.
The scientist, who had 74 this year, said that the threats include nuclear war, catastrophic global warming and viruses genetically.
"We aren't going to stop making progress, or reverse the trend, thenwe must recognize hazards and control them," he said, speaking to the Radio Times prior to the Conference.
Out of these threats, humanity will have to colonize other planets, that Hawking believes will take more than a century.
"We will not establish self-governing colonies in space for at least the next 100 years, so it must be very careful in this period," said Hawking.
In July, the Professor Hawking and Tesla founder Elon Musk has led1,000 Robotics experts in an open letter warning that "autonomous weapons will become the Kalashnikov of tomorrow."
"Probable life of human civilization is much bigger if we are a species of multi-planete as opposed to a single-planet species," Elon Musk said last year.
THE UPRISING OF ROBOTICS
Our desire to create useful digital assistants and Self driven vehicles could bring our demise.
Professor Stephen Hawking has warned that humanity is facing an uncertain future as technology learn to think for himself and to adapt to its environment.
Speaking at a demonstration in London earlier this year, the physicist told the BBC: "the full development of the artificial intelligence could spell the end of humanity."
This is echoing claims he did earlier in the year when he said the success in creating to have "would be the biggest event in human history,[but] Unfortunately, it may also be the last."
He argues that the evolution of the situation in PDAs digital Siri, Google instant, and Cortana is just symptoms of a TI arms race that "paleagainst what will bring the coming decades."
But Professor Hawking has noted that other potential benefits of this
technology could also be important, with the potential to eradicate,war, disease and poverty.
"Longer term, it there no fundamental limits of what can be accomplished," continued Professor Hawking.
"There is no physical law preventing particles of organized in a manner even more advanced than the arrangements of particles calculations in human brains"
This week, the U.S. Senate introduced a bipartisan bill authorizing a new $19.5 billion (£ 15 billion) budget for Nasa to send a crew to the red planet, but it must happen in the next 25 years to mandate
'If we're a single planet species, then eventually there will be some extinction event,' Mr Musk said.
His company SpaceX is working to send humans to space.
Last week the firm test fired one of its new Raptor 'interplanetary transport engines' which the company will use to carry astronauts to Mars.
The rocket engine is three times more powerful than the one on the Falcon 9 rockets. It will ultimately be used to launch SpaceX's manned spacecraft off our planet.
Mr Musk, chief executive of SpaceX, said the rocket will be ultimately capable of producing thrust of 690,000lbs over 382 seconds.
The engine is powered using liquid methane and liquid oxygen rather than the kerosene used in the Merlin engines of its Falcon 9 rockets.
