    What are your thoughts on other life forms out there... do you think is other life in this universe? And if there is, is it intelligent enough to try to contact us?

    The universe is so freakin' H-U-G-E it's likely that there would be other life forms out there. Hell, haven't they already found some?

    Intelligent life, I wouldn't know. Maybe we can chuck a Jimmy Neutron and stick a device into space to communicate with aliens...what? They're intelligent life forms are they not?. :eek: :p

    And what about the 95% of the universe that we can't even see--dark matter? We might be surprised to find that life is far closer than we think.

    I know some of the non-religious/anti-religious at MR can be very caustic and condescending, so I may be sticking my neck out just to get my head chopped off, but I can't help but wonder if at least a small portion of this largely imperceptible matter isn't spiritual essence, the afterlife, heaven, hell, etc. My religion says spirits are composed of matter that is simply more refined, whatever that means. I kind of wonder if dark matter is what it means.

    And, I suppose, that would count as a different kind of life form. :)

    If you can argue that the universe is large enough to accomodate other life forms--which I agree with--isn't it possible that they are so different that we might never be able to effectively communicate? Star Trek, Star Wars, etc. are so full of humanoid aliens with bisymmetric bodies, two eyes, two nostrils, two ears, and a single mouth conveniently placed in more or less the same order as our own. The Roswell/Area 51 conspiracy cranks are in love with the idea of some short, pale bug-eyed humanoid race. Well I don't buy it. If there is intelligent life out there, it could be so foreign to our way of understanding that we might not even notice each other. It could be a pool of bacteria. It probably wouldn't be DNA-based and it might be so fundamentally different that we can't begin to imagine. It could have a hive mentaility. It could be a single pan-planetary organism with no relatives or ancestors. It could be anything. Which is my point. I respect the SETI movement, but I wonder if any intelligent life in range would even want to talk--they might be antisocial or simply less curious. They might not dream of using ER or using it the way we do. The patterns they send might be so foreign as to go unnoticed by the computers. Or maybe other intelligent races killed themselves off even faster than we (probably) will. The possibilities are so endless that hope for an answer seems unfulfillable.

    There are 50-100 billion stars in our galaxy.

    There are 50-100 billion galaxies in our universe.

    Those numbers are so large, even something that has a very low chance of happening, such as the formation of life, must happen all the time. And I'd say, once you get multicellular life, it is just a matter of time before a brain arrives on the scene.

    have to agree there are just so many other stars, galaxies planets out there
    i guess there should be a place where some "pro-life" accidents happend and some intelligent life forms exist
    the problem is thou that we will perhaps never meet other life forms from other planets...the distances are just too great
    without ability to move a _lot_ faster than light ..."it's not gonna happen"

    but i have to add one of my favourite quuotes here:
    "There are 10^11 stars in the galaxy. That used to be a huge number. But it's only a hundred billion. It's less than the national deficit! We used to call them astronomical numbers. Now we should call them economical numbers."

    I agree. Scitistist toss around "light years" when talking about things in space like they are the size of city blocks. Not 5.88 trillion miles. With visable space being 13.4 BILLION light years away there is no doubt that something with a brain is out there, in my mind.

    I DO believe there's life out there. There HAS to be...

    However - the way the Universe ORIGINATED all that time ago leads me to believe that if there WERE life out there, then it would only theoretically be at the same technological level than ourselves. So, all that talk of UFO's seems a little far-fetched, especially if you consider the VAST distances needed to travel from one location to another...

    Kip Thorne's theory of Folding Space seems like the BEST idea to travel from one location to another - I think it goes something like this:

    By the use of an ENORMOUS source of energy (one yet to be found or harnessed - but he speculated the use of a Black Hole at one point...), one can "fold", or distort, space to bring two points closer together.

    Otherwise, you're stuck with the whole "Time Dilation" issue; where as you travel to a point APPROACHING TO or FASTER THAN (currently theoretically impossible - but you have to have an open mind about things) the speed of Light, then time - as YOU know it - slows down, yet stays at the constant rate outside your "sphere" of travel. Therefore, you've theoretically gone FORWARDS in time, and will have outlived your relatives by the time you return. Of course, the speed you travel is DIRECTLY PROPORTIONAL to the length of time you spend away...

    Kind of freaky, really.

    That means that any aliens, in order to travel the vast distances, would have had to do so from perhaps THOUSANDS of years previous. A bit pointless, when you consider they came ALL this way, and NOT make contact when they arrived...

    :rolleyes:

    IMO there must be other inteligent life out there somewhere! I can't beleive that given the enormous size of space/universe/whatever, our little planet is the only place where life exists.

    Ditto.. ;)

    Although the only thing that worries me, is all the 'noise pollution' we send out into space... radio, music and since the late-early 20th Century motion pictures, now think of all the stuff that's transmitted... everything including WW2+ other major conflicts, movies involving death and destruction... nevermind the dodgy music that goes with porn films... :eek: but let's face it, if other intelligent life is capable of receiving these signals, what are they going to think?? personally I reckon they'll be doing their best to avoid 'us' ever knowing about them.... either that or slipping their spaceships into 5th and getting as far away from us as possible :(

    I used to think so.... but in the last few years I'm becoming more and more convinced that we are alone in this universe. No, it's not a "god" thing either... Carl Sagan's famous analysis has a flaw in it. So let's assume that after the "mind game" you're down to a billion planets that "could" have higher life forms. Silly, as the calculation used to get there "assumes" too much. I'd be the first to admit that I am WAY wrong... when evidence comes in to support it.

    I'm partial to string theory, even though 11 dimensions leaves my brain a quivering mess. But "partial too" and "facts" are two entirely different things. One things for sure: We know pretty much nothing about the universe, and even with 100 billion worlds, there is a chance that they are quite empty.
    Hope I'm wrong... I want my daughter's daughter's daughter to be the first to shake the apendage of the emmisary from planet Wrrch-nthchgyef.
    It's all crap.

    Well, the numbers of stars in the galaxy and the number of galaxies in the universe are built on assumptions that are pretty well supported. I assume you are talking more about the "chance of life". Sure, tons of assumptions there.

    But no one has any idea. My feeling is, it has happened here, so it is possible. If we see evidence of it on Mars, then it probably has happened thousands of times in each galaxy. To me, the assumptions needed to say there is no life anywhere but here are more unlikely than those needed to say there is life elsewhere.

    The bigbang is constantly going out in every direction creating planets, stars, space. Ok, the farthest object we have ever seen from earth is 13.8 BILLION LIGHT YEARS away. Thats just what we can see. However theroreticaly space goes on forever in every direction. Now use the volume of a sphere equation and insert 13.8 Billion light years as the dimaiter. Think of how many cubic light years that is. And that's just a fraction of the volume of space. The odds of a planet that has water or another earth like plannet is a giant number. It doens't even have to have water to support life. Carbon, silicone? Or an element we don't even know about. Then the odds get even higher.

    There's a cool book out there by Isaac Asimov, entitled "Extraterrestrial Civilisations".

    It gives a scientific and mathematical process as to find the possible existence of extraterrestrial life. Using basic statistics, and our crude knowledge of the CURRENT size of the Universe, it breaks down, chapter by chapter, the feasibility of life out there.

    If anything, it's an interesting read - and it CERTAINLY gets you thinking...

    No more matter is being created. All of the stars and planets and galaxies are already here, they're just spreading out. I think by the latest estimates, there are more like 400 billion stars in our galaxy, and 200 billion galaxies. that works out to about 80,000,000,000,000,000,000,000 or 80 quintillion stars. Even if only one in a billion had planets (actually, the percentage is far more than that) That's still, at the very least, 80,000,000,000,000 or 80 trillion planets. Of those, there has to be at least one with some form of life. Heck, there might even be other life in our solar system, like under the ice on Europa, where there's a liquid ocean. Mars probably had life at one point, too.

    With billions of stars in a galaxy, and billions of galaxies, there's got to be life out there. In fact, theres a good chance that there's a lot of life out there. If it can happen once, it can happen again. In fact, if you assume the universe to be infinite, (which it probably isn't) anything that can happen has or will happen, and more than likely will happen multiple times. If we are alone, it seems like an awful waste of space.

    If there isn't it's an awfully big waste of space.

    Just think of the logistics though.
    earth is 4 and a bit billion years old. and humans have been space capable in some fassion for 50 years.

    I think it's more likely than not that there is other life out there in other galaxies, and less likely than not that we will be able to communicate with it, because of the distance separating us. Life on Mars would be a lot easier to talk to than life in another galaxy.

    here's the problem with having a planet with intelligent life... the species has to evolve in... the life of its star, the time between major astrological collisions, and it has to be able to evolve to a high enough level before it destroys itself.

    Also, if there is more intelligent life out there, why would we want it to come over here? That would be like the United States fighting WWI over again, only we had the technology of today back in 1918. Or maybe even present day America vs. 1776 Britain. Their technology would be so much greater than ours if they figured out a way to travel across the universe.
