Sorry, but your conclusion doesn't follow from your premise... why does the origin point of the universe have anything directly to do with the complexity of conditions for life? (just a comment...)

 

Actually is has everything to do with it........

 

Our planet relies upon the position of both the sun and moon..........our atmosphere is also very complex with the correct combination of gases. With these conditions I think our planet is unique. It has its own unique position with in in the universe created by the big bang.

 

The origin of the point of the universe has a lot to do with it actually……..here is an idea………..get a large bag of marbles (say 100) tip them out on one point on the floor (simulating a big bang effect) and you will see out of the 100 marbles no marble measures the exact same distance from another. The distance representing the conditions for life to evolve. Ok now get a bag of a million marbles and then tip that out on the same point on the floor…….probability is increased because there are more marbles……..we find that probabiluity dictates that there must be one marble thats teh same distance from another (but we are still not certain)...........but one marble represents only one factor……..so then we multiply the number of factors to sustain life (as we know it) to provide a figure. Put it this way………it’s a chance in hell!

 

Sorry, there are no aliens............probability is too high.

But you are assuming that only semi-human carbonbased life can exist. What about silliconbased life forms??? or whatever.... you can't predict what you don't know, so probabilitie doesn't apply here.

He's also using millions of marbles, as opposed to billions, and only in the area we can see... and that's a -galaxy- count, not a -star- count, and each galaxy would have a rather enormous number of stars (the estimated number of stars per galaxy is between 10-200 billion stars (given a range between galaxies 10%-200% of the size of ours)). The chances for life go WAY up with that sort of quantity...

 

... given the estimations of the age of the universe, and the fact that it's outer edge is likely expanding at the speed of light, it's WAY bigger than the observable universe (and those areas aren't likely to be any less star-filled than what IS observable...)

Whoever voted "no, there is no alien life" is pretty damn short sighted.

 

show yourself mr. "God created humanity and only humans have souls". *rolls eyes*

 

The universe, without gratuitious use of meaningless terms like "known" (we don't *know* a fraction of what there is to be *known* about the "known" universe *rolls eyes again*) is huge and vast.

 

point being there are some 200-400 billion stars in this galaxy, how many hundreds of billions, perhaps trillons of galaxies in the universe, some larger and some smaller than the milky way galaxy. Given THAT DAMN MANY it's an absurdly tiny fraction to even hypothesize that something like 100 intelligent species per galaxy would exist, insanely, INSANELY tiny - and that's just assuming the kind of life form we are.

 

this is completely ignoring the possibility of life forms that are spawned, evolve, exist and die out in star systems where solar evolution causes the planet to only be habitable for say 100 million years out of the star's life span. Just b/c our sun has been relaxed enough to be a main sequence star for about 5 billion years doesn't mean biological evolution has to be so lazy everywhere else, maybe other races are born and die within a few million years. astronomical phenomena like solar storms, gamma ray bursts, comet collisions, meteor showers - all of these things can affect life in more ways than just negatively. What if a star system that we would classify as not being able to support life blurbs out a burst of solar storms that irradiates a planet, forces monumental genetic mutation in some base life form like single celled organism and 10 million years later you've got an Asgard.

 

a person doesn't even have to look at how likely it is that there is other humanoid/carbonbased/sun-like-solar-system/earth-like races out there, you can just imagine that beyond our particular "style" of life there are hundreds of other configurations. It's endless, and undeniable.

 

you know right now, at this very moment there could be multi cellular, even intelligent aquatic life on Europa, or rather *IN* Europa since it's believed to contain liquid oceans beneath miles of ice and possibly geothermal energy to maybe sustain life....And we'd never friggin know it, not until we go there anyway ;)

 

the possibilities are endless :)

i belive that they are already here looking like us and walking around with us everyday, its all a big cover up by the gov's of the world and the "New World Order"

 

or maybe ive watched to much X Files and played to much Art Bell

 

but hell i belive theres more out there

I'd definately agree that there's likely to be life all over the place out there in the universe.

 

As to whether there is intelligent life amoungst it?

 

Well is intelligence a trait that offers a real long term (in terms of the timescale of the universe) benefit for a species?

 

At face value, you might say yes. But the fact is dinosaurs managed to last millions of years. At this rate, it is entirely feasable that at some point that the human species destroys the very biosphere it depends on. As agent Smith says in 'The Matrix', "Human beings are a disease, a cancer on this planet. You are the plague."

 

And it's true. Looking at the relevent graphs representing population growth, human population has been growing at a rate that almost exactly matches that for a typical plague species. You see, intelligence means that the usual biological and environmental facts limiting population growth become irrelevant.

 

And in the end... evolution doesn't tend to keep a place for plague species.
