Aliens may exist but contact would hurt humans: Hawking
Quote:
LONDON (AFP) – Aliens may exist but mankind should avoid contact with them as the consequences could be devastating, British scientist Stephen Hawking warned Sunday.
"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," said the astrophysicist in a new television series, according to British media reports.
The programmes depict an imagined universe featuring alien life forms in huge spaceships on the hunt for resources after draining their own planet dry.
"Such advanced aliens would perhaps become nomads, looking to conquer and colonise whatever planets they can reach," warned Hawking.
The doomsday scenario is suggested in the series "Into the Universe with Stephen Hawking" on the Discovery Channel, which began airing in the United States on Sunday.
On the probability of alien life existing, he says: "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."
Glowing squid-like creatures, herds of herbivores that can hang onto a cliff face and bright yellow predators that kill their prey with stinging tails are among the creatures that stalk the scientist's fantastical cosmos.
Mankind has already made a number of attempts to contact extraterrestrial civilisations.
In 2008, American space agency NASA beamed the Beatles song "Across the Universe" into deep space to send a message of peace to any alien that happens to be in the region of Polaris -- also known as the North Star -- in 2439.
But the history of humanity's efforts to contact aliens stretches back some years.
The US probes Pioneer 10 and 11 were launched in 1972 and 1973 bearing plaques of a naked man and woman and symbols seeking to convey the positions of the Earth and the Sun.
Voyager 1 and 2, launched in 1977, each carry a gold-plated copper phonogram disk with recordings of sounds and images on Earth.
why does nasa waste money on trying to find ET life?
what does it achieve when we do find them?
in the short time that humans have left on this planet i doubt we'll come in contact with any life with comparable intelligence to humans
If you look at the math, its absolutely staggering at the number of earth-like planets that theoretically exist. Even at most, CONSERVATIVE estimates, based on the randomization of planetary systems, there are approximately 25,000 planets in the universe that are identical to Earth. Using non-conservative estimates, they go into the hundreds of thousands-millions.
And of course they haven't 'contacted' us because of the immense distances.
If anyone needs a reminded of the magnitude of the universe:

of course we are not alone in this universe. I can saw for sure alien lifeforms would need some source of fuel to power their lifeforms as we do food and air. also they will be a dominating force if we do encounter them because the theory of evolution says the weak die off and the strong flourish. these aliens would look for ways to promote their own well being regardless if that means helping us or killing us.
i say my curiousity for the encounter of these aliens outweighs the dangers that may be posed onto us in the case of encounter.

So you enjoy being a native indian? (referencing the OP )
it doesnt have to be traditional green men to be considered "alien" though
the smallest living bacteria on another planet would be enough, and the odds of somthing like that seems very likely
True. There's speculation that there are bacteria, possibly 'sea' life underneath the thick ice layer in Saturn's moon Europa, near the moon's core, which acts as an power source.
Scientists have long thought that the sun is a requirement for life, but recently that has been disproven with the discovery of extremophiles in sub-terranean caves. These bacteria thrive on geothermal activity in pitch black.
If we could find life in the form of bacteria in these moons, it would probably be one of the most important scientific discoveries of all time. Not to mention the philosophical/religious implications would be huge.

but on a more serious note - what if these alien lifeforms exists not in our visible spectrum, but rather in some other reach of the electromagnetic spectrum? What if what they view is tangible is actually a solid to us and vice versa?
It's right there in the bible! At least it will be, when it happens. We'll have to find out which parts to twist and reinterpret to suit our needs. PRAISE THE LORD~!
