Hawking, 68, has long suffered from a motor neurone disease that
has extremely limited his powers of communication and movement, but
that has never stopped him from making important contributions
to scientific theory. Hawking just finished up a three-year
project, a TV series called Stephen Hawking's Universe, which
will air on Sunday May 9 at 9 p.m. on the Discovery Channel.In
the show he will offer up some controversial assessments on
extraterrestrial life and what it might be like. Hawking
is a firm believer that alien life does exist. The universe
contains hundreds of billions of galaxies, each with hundreds of
millions of stars, many which have been shown
to have planets in orbit. Numbers virtually guarantee
that life has evolved elsewhere, Hawking believes. He states,
"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."So what might these
extraterrestrial species be like? Hawking believes that most
are likely "simple" species, similar to those that have
evolved on Earth; ranging from microbes to land animals.However,
Hawking believes there is likely intelligent life out there.
And he's frightened by that possibility.The aliens in
Hawking's vision would be much like the malefic beasties in the
blockbuster science-fiction flick Independence
He describes, "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 colonize whatever
planets they can reach."He says that humans should try
to avoid alien contact as we colonize
space. He states that such contact would be "a little
too risky". What would result? He states, "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."In addition to his
theories about vicious aliens, Hawking suggests that based on
examples of life surviving on Earth in extreme environments, life
could be found in unbelievable places, such as in the center of stars
or even floating in interplanetary space.Hawking's colleagues
concur on this point. Lord Martin Rees, a British royal
astrophysicist, told his students in lecture earlier this year that
humans might not be able to recognize or understand forms of life
they stumble across in space. He states, "I suspect there
could be life and intelligence out there in forms we can’t
conceive. 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."How close could primitive life
be? Professor Brian Cox, University of Manchester's "rockstar
physicist" suggests we look in our own solar backyard. He
says that Mars, Europa (a moon of Jupiter), and Titan (a moon of
Saturn) are likely places to find it.

Nor will we ever colonize Mars or Venus, to say nothing of the other planets, although I guess its possible that we could eventually put some kind of a small base on Mars kind of like we have in Antarctica, if we ever got our act together and decided to seriously push the space program.
quote: But ask them if they are 100% positive it's a fact, and I bet you they would then go back to saying the evidence "could" support that. Simply meaning, it's not a fact, and to assume so is wrong!
quote: To this all I can say is that at one point in time "Physics" stated that heavier then air flight was not possible!
quote: Fact is there are already many possibilities out there that do allow for FTL travel, while they may not be proven facts, the truth is they have not been "unproven" either. Thereby to state that FTL is not possible, is quite simple a false statement. Truth is, science can prove that it might be possible, we just have no means to test it to prove which side "is" fact.
quote: bottom line is he was rated down...
quote: To this all can say is if everyone stopped projects because they were told it's not possible, then we would probably still be living in caves! As many of today's innovations were once thought, "Not Possible"
quote: At some point you have to go with what is within the realm of probability and not get carried away with hypotheticals. There are some very smart people (I've mentioned some names in my other posts) out there saying that the SETI program is a waste of money and should be shut down because the likelihood of another intelligent species existing anywhere else in the Universe is basically NILL.
quote: I don't think physics ever stated this. The fact of the matter is that anyone could look up in the sky and see birds flying around and realize that heaver than air flight was possible.
quote: Unless Einstein's theory of special relativity is fundamentally wrong (and its been proven correct over and over again in various experiments), anything with mass travelling faster than the speed of light is physically impossible.
quote: But I still hold to my position that we will never leave the solar system. Let's be frank here, we can't even balance our national budget and make social security or medicare solvent. And if we can't do those very basic things, colonizing a planet around Alpha Centauri is impossible.
