"The human race shouldn't have all its eggs in one basket, or on one planet," the renowned astrophysicist told the website Big Think, a forum which airs ideas on many subjects from experts.
"Our only chance of long-term survival is not to remain inward looking on planet Earth, but to spread out into space," he added.
He warned that the human race was likely to face an increased number of events that threaten its very existence, as the Cuban missile crisis did in 1962.
The Cold War showdown saw the United States and Soviet Union in a confrontation over Soviet missiles deployed in Cuba, near US shores, and brought the world to the brink of nuclear war.

A massive asteroid might crash into Earth in 2182, scientists have warned.
The asteroid, called 1999 RQ36, has a one-in-thousand chance of actually hitting the Earth at some point before the year 2200, but is most likely to hit on September 24, 2182.
The asteroid was first discovered in the year 1999 and is more than 1,800 feet across. If an asteroid of this size hits the Earth it would cause widespread devastation and possible mass extinction, reports the Daily Mail.
Scientists say that any attempt to try and divert the asteroid will have to take place at least 100 years before it is due to hit to have any chance of success.

Mexican authorities have arrested a man who was trying to smuggle 18 small monkeys into the country by carrying them in his clothing.
Roberto Sol Cabrera, a Mexican citizen, was stopped at a random check at Mexico City's international airport after arriving from Lima.
In a statement, police said Mr Cabrera Zavaleta had been behaving "nervously".
Once he was searched, it was discovered that he had hidden 18 titi monkeys in a girdle around his waist.
After his arrest, Mr Sol Cabrera confessed that the animals had travelled in his luggage, and that he had put them under his clothing "to protect them from X-rays" as he was going through customs.
The animals had been put into socks, police explained, and two of them were dead at the time of confiscation.

Divers have found bottles of champagne some 230 years old on the bottom of the Baltic which a wine expert described on Saturday as tasting "fabulous."
Thought to be premium brand Veuve Clicquot, the 30 bottles discovered perfectly preserved at a depth of 55 metres could have been in a consignment sent by France's King Louis XVI to Russian Tsar Peter the Great.
If confirmed, it would be by far the oldest champagne still drinkable in the world, thanks to the ideal conditions of cold and darkness.
"We have contacted (makers) Moet & Chandon and they are 98 per cent certain it is Veuve Clicquot," Christian Ekstroem, the head of the diving team, told AFP.

At last octopus paul who predicted the FIFA WC 2010, is set to get away from the media and the world eye.
The Sea Life Oberhausen aquarium's spokeswoman Tanja Munzig told AP Television News on Monday that the intuitive invertebrate will "go into retirement and do what he likes to do best: play with his handlers and delight children who come visit to him."
Oberhausen is located in Germany, where Octopus Paul was born.

You might have seen dolphin dancing to the tunes of his master in zoo show. People love such dolphin to its loving and interactive nature, one such popular dolphin is 'Moko' which even made headline through the world for finding out and rescuing two stranded whales.
Moko was a familiar sight around the North Island's eastern beaches, swimming among bathers but sometimes blocking them from reaching shore.
Conservationists confirmed the carcass of a bottlenose dolphin was "probably" Moko, and tests are being done.

As one of my post reported that plane powered by sunlight is being tested for the night time and the BBC reports says that the mission, i mean the test flight was successful and had continuously flow through out the night, continuously for 26 hrs.
The plane landed at Payerne airport after a total flight time of 26 hours.
During the flight it reached a height of 8,700 m (28,543 ft).
Assistants rushed to stabilise the experimental aircraft as it touched down, ensuring that its huge 63m (207ft) wingspan did not scrape the ground and topple the plane.
Car to run with 'petrol made from CO2'

Scientists are inching closer to produce a new fuel from carbon dioxide and sunlight which they claim will help meet world's energy needs and minimise carbon emissions.
A team at Sandia National Laboratories in Albuquerque, New Mexico, is developing the technique which will produce "synthetic liquid fuels" in solar-powered reactors.
Experiments have also shown that the reactors can absorb carbon dioxide (CO2) and turn it into carbon monoxide. The same reactors can also be used to turn water into hydrogen and oxygen.
The two can then be reacted together with a catalyst to form hydrocarbon fuels, in a technique known as the "Fischer-Tropsch" process.

The former Formula One engineer who created the iconic McLaren F1 supercar has officially unveiled the T.25 -- his idea for a new class of city car.
Murray and his team based in Shalford, south east England, have been working on the design for the past three years and, until now, have kept the exact details of the car firmly under wraps.
At less than eight feet long and a little over four feet wide, the T.25 is smaller than Daimler AG's popular Smart car, and a petrol engine model will retail for around $9,000.
The centralized driving position -- also a feature of Murray's McLaren F1 -- and central instrumentation and controls are perhaps its most obvious traits borrowed from Formula One.
Cell Phone Radiation reallys does effects Bees: Study

A new study has suggested that cell phone radiation may be contributing to declines in bee populations in some areas of the world.
Bee populations dropped 17 percent in the UK last year, according to the British Bee Association, and nearly 30 percent in the United States says the U.S. Department of Agriculture.
Parasitic mites called varroa, agricultural pesticides and the effects of climate change have all been implicated in what has been dubbed "colony collapse disorder" (CCD).
But researchers in India believe cell phones could also be to blame for some of the losses.
In a study at Punjab University in Chandigarh, northern India, researchers fitted cell phones to a hive and powered them up for two fifteen-minute periods each day.

The teeth of "Leviathan Melvillei" were so large it was initially assumed they were elephant tusks.
"There were no elephants in South America before 3 million years ago, and the specimens found have an age of 12 to 15 million years, so that was impossible," said Professor Jelle Reumer, one of the team of scientists who found the fossil in the Pisco-Ica desert in coastal Peru.

Reports say the 2m (6.5ft) female elephant was tracked down in Maungdaw in the west of the country.
White elephants are only nominally white - they often look reddish-brown in the sun, and light pink when wet.
Analysts say the animal is likely to be brought to the capital, Naypyidaw, for the military ruler, General Than Shwe.

Known as a geoid, it essentially defines where the level surface is on our planet; it tells us which way is "up" and which way is "down".
It is drawn from delicate measurements made by Europe's Goce satellite, which flies so low it comes perilously close to falling out of the sky.
Scientists say the data gathered by the spacecraft will have numerous applications.

This data comes from a new survey out this week in the Proceedings of the National Academy of Sciences.
The study found that 97 percent of scientific experts agree that climate change is "very likely" caused mainly by human activity.
The report is based on questions posed to 1,372 scientists. Nearly all the experts agreed that it is "very likely that anthropogenic greenhouse gases have been responsible for most of the unequivocal warming of the Earth's average global temperature in the second half of the twentieth century."
As for the 3 percent of scientists who remain unconvinced, the study found their average expertise is far below that of their colleagues, as measured by publication and citation rates.

Yissum Research Development Company Ltd., the technology transfer arm of the Hebrew University of Jerusalem, has just introduced what they're calling "solid organic electric battery based upon treated potatoes." In short, it's a potato powered battery, and it's as real as you're hoping it is.
The simple, sustainable, robust device can potentially provide an immediate inexpensive solution to electricity needs in parts of the world lacking electrical infrastructure, but we're hoping that it can work a similar amount of magic for developed nations as well.
Researchers at the Hebrew University discovered that the enhanced salt bridge capability of treated potato tubers can generate electricity through means readily available in the developing world. This cheap, easy to use green power source could substantially improve the quality of life of 1.6 billion people, comprising 32% of the developing non-OECD populations, currently lacking access to electrical infrastructure. Such a source can provide important needs, such as lighting, telecommunication, and information transfer.

I don't think so, this soon possible unless we are struck with Natural disaster. This claim was made by an Australian scientist named Frank Fenner.
He was the one who helped in eradicating smallpox around the world.
Professor Frank Fenner, emeritus professor of microbiology at the Australian National University, has claimed that the human race will be unable to survive a population explosion and “unbridled consumption”.
“It’s an irreversible situation. I think it’s too late. I try not to express that because people are trying to do something, but they keep putting it off,” Prof. Fenner said.

GONE RENEWABLE Synthetic rubber, produced using biotechnology.
86 percent of the tire’s environmental impact revolves around how it affects fuel consumption. Only 12 percent of the carbon dioxide emissions associated with tires arise from the raw materials and manufacturing.
Tire makers say that fuel economy improvements of 4 to 8 percent over conventional tires are typical for these energy-saving designs. The low-rolling-resistance designs use silica-based mineral fillers, rather than just the standard carbon-black reinforcing fillers, to reduce friction.
the research laboratories at several tire makers are making progress toward reversing the trend of increased petroleum content. One of the first to pursue this path was Sumitomo Rubber Industries, which has a global alliance with Goodyear in the Dunlop brand, for the Enasave tire it introduced in Japan in 2006. Among other changes, Sumitomo engineers substantially reduced the amount of petrochemicals by cutting the amount of synthetic rubber in half, to 11 percent of the tire’s composition from about 22 percent.

The team, led by adventurer Bertrand Piccard, says it will try to fly the Solar Impulse nonstop for 24 hours as part of its test program.
It says the pilot, Andre Borschberg, will need to conserve enough battery power during the day to make it through the night.
Borschberg says being able to fly through the night will allow the plane to stay airborne for successive cycles and come close to permitting perpetual flight.
