based On Probabilities Alone.

Ok, now how big is the Universe again? Too big to measure, right? Yet there are actually those who believe that merely because we haven't captured one in a jar, there is no life on other planets? Really?
Anyone who's been exposed to a statistics class can see that based on probabilities alone, humans are not the be-all, end-all of life that exists, other than in our own little arrogant, finite minds.

Great question but...When we ask questions of that sort we are never aware that our human sense-perceptions are super-limited, and better to say - undeveloped. No matter how "well" we "see" " the world" through telescopes or microscopes, all these impressions have to be processed through our old, super limited human sense-perceptions. Remember great Protagoras? or I. Kant?



We have not learned much since..... Our sciences are still based on the most outdated mentality since Descartes!! Read outstanding sage - W. Heisenberg. Think on your own, and be as intuitive as you can. Please remember, that our best knowledge is still based on the "evidence" of the most deceiving perception of all we possess - our sight!



The external world is not about creating the Universe with its stars and planets, or black holes for us, and it has no TIME to show us how it "looks" - it changes ENTIRELY, in every instant, so are we, and the rest of all living forms. No telescopes or microscopes can really "capture" any actual evidence" of anything but our own limitations. The laws of nature out there are still unknown to us. We need to Start new sciences based on a new philosophy, and new knowledge about our own human nature and its limitations, by trying to change our limitations and stiff conventions.

About "aliens" - again, our limitations do not allow us to sense much, and I imagine that myriads of different living existences are right HERE, "going" through us, but we do not sense a thing.... Life is everywhere - it changes this fascinating world.

anti3tastic, None of that makes sense to me. First of all, the title of the group is "I believe life exists beyond planet Earth". That means that it COULD be one amoeba on a planet billions away, or it COULD be an intelligent being in our galaxy. The title does not suggest what life, or if it can make it to planet Earth. Secondly, the universe is ever expanding. That's actually what the group picture shows. They are pillars of creation. That's one image of a set. As for the Multiverse Theory that you mentioned, Stephen Hawking is the one who presented it. That's irrelevant however, because this is not about if "they" could get here. Thirdly, I think that you should try to be a little bit open minded and realise that, just because science is incapable of proving something now, it doesn't mean it doesn't or cant exist. I am not a mathematician, but I understand probability. If you knew more about Einstein, you would not try to use his theories to make us look ignorant. He actually suggested the possibility of time travel. By the way, I already knew what you meant about "under 30". You don't have to call all of us stupid. I don't even know what to say about the end of your post. I just think it takes more of a stretch to get to that conspiracy than to life beyond Earth.

Everyone is all enthusiastic about "aliens." Oh well, I'm going to be the Scrooge that throws cold water on this "hope."

What if Einstein is correct? Any of you think of that? ( Are any of you under 30? Most likely, you guys don't even know what I'm talking about! ) That means that the absolute speed limit in the universe is the speed of light. This could make it mighty hard for these other "intelligent beings" to get here, or to even send radio signals, unless they are from a relatively close star. Even in that case, you are talking LIGHT YEARS!

OK, you can argue for the possibility of intelligent life SOMEWHERE, but that somewhere, if it isn't at the VERY nearest stars, is likely hundreds or thousands, or even millions of LIGHT YEARS away!!! This makes it hard to ever PROVE that there is intelligent life anywhere.

I could be wrong, but I will state my opinion. I think that if it involved intelligent life from the very nearest star systems, they would have been here by now. And I'm assuming that these creatures are advanced indeed, if they can travel even somewhere NEAR the speed of light. If they can't do that, a voyage to Earth may very well take hundreds of years! Well, then again, maybe they aren't so advanced. I will even say that, maybe, there is nothing there! Let your imagination take you to that possibility, too!

If you say that the possibilities are limited only by what your imagination will allow, that could be true. But, aside from your quasi-mystical new age physics, what do you really know for sure? Yes, there could be something to the idea of different dimensions. A lot of that is pretty dreamy and theoretical. Just because it's mentioned in some sci-fi program, doesn't make it fact.

I think there is a reason why the media is pushing all the "friendly alien" and possibility thinking on this subject.

Yes, I think that life may exist in forms other than what we're familiar with but, so far, no proof. What there IS proof of is that the technology exists right here on earth, to STAGE an alien invasion, in order to control the population!!

Oh yeah. There's every reason to believe there's other intelligent life expressions "out there."

We truly are the universe trying to understand itself. Cloned realities that each occupy

a different place; draft versions of a story in-process, and ONE chapter is the human race.

Our souls are extended throughout a simultaneous now. Forever wherever, limited only by what imagination will allow. And that's just this universe. Put in this perspective, we are like tiny ants crawling on one single blade of grass...

I too believe that there is some kind of life out there somewhere. If not, what's the use of the other planets and universes' out there? What I find absolutely mind boggling is that there's a very good possibility that there is no end to space. It's just too much to imagine and why would the human species be the only one to evolve? Anyway, that's all I have to contribute.

Hah hah. Unnecessary censorship.

what?

Well, based on the recent NASA kepler mission, around 5-6% of stars contain earth-size planets that lie in the "habitable zone" around a star. In other words, temperature conditions conducive to liquid water. Of course they may be planets like venus or mars. It's impossible to say what the probability of them ACTUALLY having liquid water conditions at current. But nevermind that.



There are are around 100 billion stars in our local galaxy, give or take 25%. A lot of them are smaller than the sun. That means 1-10 billion earthlike planets.



So my educated guess would be on the order of less than a billion to several billion planets with liquid water and earthlike conditions.



The odds of them developing life...considering the ubiquity of microbes on almost every environment here on earth, is fairly good.



Also, earth has several species that are highly intelligent creatures with a complex social and communication system,such as elephants, orcas, ***** whales, african gray parrots, etc. So you have to consider that although intelligent life is probably by no means rare, many of them may not have the capacity, or the interest for radio technology.
