Stephen Hawkings Warning

[oldeno]

No need to worry.Let it be for new generation to find how they look like.We are glad to live this far.

Aliens almost certainly exist but humans should avoid making contact, Professor Stephen Hawking has warned.
In a series for the Discovery Channel the renowned astrophysicist said it was "perfectly rational" to assume intelligent life exists elsewhere.
But he warned that aliens might simply raid Earth for resources, then move on.
"If aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans," he said.
Prof Hawking thinks that, rather than actively trying to communicate with extra-terrestrials, humans should do everything possible to avoid contact.
He explained: "We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet."
The real challenge is to work out what aliens might actually be like



In the past probes have been sent into space with engravings of human on board and diagrams showing the location of our planet.
Radio beams have been fired into space in the hope of reaching alien civilisations.
Prof Hawking said: "To my mathematical brain, the numbers alone make thinking about aliens perfectly rational.
"The real challenge is to work out what aliens might actually be like."
The programme envisages numerous alien species including two-legged herbivores and yellow, lizard-like predators.
But Prof Hawking conceded most life elsewhere in the universe is likely to consist of simple microbes.
In the recent BBC series Wonders of the Solar System, Professor Brian Cox, a physicist from the University of Manchester, also suggested life may exist elsewhere within our solar system.
He said organisms could be present under the ice sheet that envelops Europa, one of Jupiter's moons.
Professor Cox added: "Closer to home, the evidence that life could exist on Mars is growing.
"We will only know for sure when the next generation of spacecraft, fine-tuned to search for life, are launched to the moons of Jupiter and the arid plains of Mars in the coming decades."

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.

?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.?
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:
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.?
Stephen Hawking's Universe begins on the Discovery Channel on Sunday May 9 at 9pm

after watchin V i think we should blow the shit ot of anything that comes near us ..

after watchin V i think we should blow the shit ot of anything that comes near us ..

if they ever get anywhere near earth we wont stand a chance,
the best thing to do is find them first and suss out if they are friendly or not?.

Traveling at the speed of light is impossible so if say their world is 1 light year away they would all be dead by the time they got here. Not much of a fight then. And Stephen Hawking knows this so what the hell is he wittering on about.

[mikeslocks]

Silica life forms cell division might not degrade and get old like carbon based humans that mean they could live for ever. Mel Gibson could boar them to death about who already owns everything. Aliens could eliminate the Jersey Shore cast and make life on earth bearable again and reruns of the yankers.

Traveling at the speed of light is impossible.

So how does light travel then?

its not impossible there is something that can travel at the speed of light

but tbh i dont know about all this moon and meeting aliens and space travel i think we are just getting a little bit carried away

i cant even get a letter cos theres an inch of snow outside

[alexics]

Photons are the only thing that can travel at the speed of light and they are considered massless. The amount of energy needed to travel at the speed of light approaches infinity the nearer it gets to that speed. Also the objects mass increases. It's all because of the equation e=mc2. You can plot this relationship using the gamma function but it is a very uninteresting thing to do.

radio waves travel at the same speed, 186,000 mps

I don't believe everything is what it appears to be, these facts that scientists proclaim to be facts where at one point just an idea, sometimes things are believed until seen in a different light such as the world being flat.

Who is to say that one day we won't find something out that will suggest traveling at the speed of light can be possible ?


Does this video open you're mind at all ?

To what?

The double slit experiment is standard in the teaching of wave-partical duality.
The effect was first noticed by Isaac Newton in the 17th Century and refined by Thomas Young in the 18th. I learned it in school.

There's nothing "mind opening" about it.

It changes behaviour when they try to observe it. As if it knows when it is being watched.

i understand what youre saying completely
quite interesting analogy
