Don’t talk to aliens, warns Stephen Hawking (VIDEO)

Don’t talk to aliens, warns Stephen Hawking (VIDEO)

The aliens are out there and Earth had better watch out, at least according to Stephen Hawking. He has suggested that extraterrestrials are almost certain to exist — but that instead of seeking them out, humanity should be doing all it that can to avoid any contact.

The suggestions come in a new documentary series in which Hawking, one of the world’s leading scientists, will set out his latest thinking on some of the universe’s greatest mysteries.

Alien life, he will suggest, is almost certain to exist in many other parts of the universe: not just in planets, but perhaps in the centre of stars or even floating in interplanetary space.

Hawking’s logic on aliens is, for him, unusually simple. The universe, he points out, has 100 billion galaxies, each containing hundreds of millions of stars. In such a big place, Earth is unlikely to be the only planet where life has evolved.

“To my mathematical brain, the numbers alone make thinking about aliens perfectly rational,” he said. “The real challenge is to work out what aliens might actually be like.”

The answer, he suggests, is that most of it will be the equivalent of microbes or simple animals — the sort of life that has dominated Earth for most of its history.

One scene in his documentary for the Discovery Channel shows herds of two-legged herbivores browsing on an alien cliff-face where they are picked off by flying, yellow lizard-like predators. Another shows glowing fluorescent aquatic animals forming vast shoals in the oceans thought to underlie the thick ice coating Europa, one of the moons of Jupiter.

Such scenes are speculative, but Hawking uses them to lead on to a serious point: that a few life forms could be intelligent and pose a threat. Hawking believes that contact with such a species could be devastating for humanity.

He suggests that aliens might simply raid Earth for its resources and then move on: “We only have to look at ourselves to see how intelligent life might develop into something we wouldn’t want to meet. I imagine they might exist in massive ships, having used up all the resources from their home planet. Such advanced aliens would perhaps become nomads, looking to conquer and colonise whatever planets they can reach.”

He concludes that trying to make contact with alien races is “a little too risky”. He said: “If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the Native Americans.”

The completion of the documentary marks a triumph for Hawking, now 68, who is paralysed by motor neurone disease and has very limited powers of communication. The project took him and his producers three years, during which he insisted on rewriting large chunks of the script and checking the filming.

John Smithson, executive producer for Discovery, said: “He wanted to make a programme that was entertaining for a general audience as well as scientific and that’s a tough job, given the complexity of the ideas involved.”

Hawking has suggested the possibility of alien life before but his views have been clarified by a series of scientific breakthroughs, such as the discovery, since 1995, of more than 450 planets orbiting distant stars, showing that planets are a common phenomenon.

So far, all the new planets found have been far larger than Earth, but only because the telescopes used to detect them are not sensitive enough to detect Earth-sized bodies at such distances.

Another breakthrough is the discovery that life on Earth has proven able to colonise its most extreme environments. If life can survive and evolve there, scientists reason, then perhaps nowhere is out of bounds.

Hawking’s belief in aliens places him in good scientific company. In his recent Wonders of the Solar System BBC series, Professor Brian Cox backed the idea, too, suggesting Mars, Europa and Titan, a moon of Saturn, as likely places to look.

Similarly, Lord Rees, the astronomer royal, warned in a lecture earlier this year that aliens might prove to be beyond human understanding.

“I suspect there could be life and intelligence out there in forms we can’t conceive,” he said. “Just as a chimpanzee can’t understand quantum theory, it could be there are aspects of reality that are beyond the capacity of our brains.”

  1. Says there is no God from els were but says do not chat to aliens funny wet of strife do tell him to try wisdom in for a try 🙂 bless God the holy of holys the all and you all as is as was is as is

  2. Their flying crafts are invisible…even they can be invisible…I also believe they won’t eat us lol. And yes they are far advanced beyond the word we call technology

  3. Here is the model of the car on compressed air.
    Just imagine how the world would have looked like by now if humans would have left the oil where it belonged. In the earth.
    This car was fully operational in 1932

  4. There is no lack of energy sources here on earth.
    There is just a multitude of bad choices.
    There were cars on compressed air in the 1930 ‘s, but the problem was that it is a cheap, clean and efficient principle.
    And, most of all, the compressed air system makes it possible for most individuals to produce their own energy supply.
    With firewood, waterpower, windpower, solar etc etc.

  5. Replace aliens with energy companies, especially oil, for the reason the moons off limits. They know the HE3 (Helium 3) on the moon will solve our energy needs for millenia. Its safe, non-poluting and their is heaps of it. They would be out of business overnight

  6. So far the scenario is such that there was an invitation sent into space about how friendly humans are and a warm welcome was written as a promise.

    But when an airforce sees a flying metal bal or anything else they dont understand, they use it for target practising, without wondering how this thing can fly without wings.
    They shoot first and investigate later.

    A despicable species, with a few exceptions.

  7. Can imagine what aliens would think of the human race checking the comments thoughts and beliefs of the world’s elite .Their knowledge of aliens is so disappointing after all the direct clues put on purpose to enlighten us of their existence. It’s obvious doesn’t apply to all, much still to be done to eliminate this ignorance. They will know how to proceed to this end.

  8. Solar system is not only belongs to humans or creatures in earth , if some life’s exists in our milky way or even from interstellar may considering us as aliens …. well I have only interest to learn about it , but for me religious attitude of people like kind of aliens
