    What if there was life in another galaxy? Not extraterrestrials, but just normal humans. And they were in the same situation as us like they, too, were

    think about if there could be life somewhere else. And we would never even know... And it wasn't just antimatter it was real people. Do you think

    this could be possible?

    Have you read Aleksei Tolstois' "Aelita"? A fine art of early Russian science fiction. I think it can! Or if you read/ watch Star Trek, you will know that you will see their "alien hypothesis" around the galaxy.


    It is by will alone I set my mind in motion.

    Absolutely. There is no reason to believe that we are the only intelligent life form in the universe, and likewise there is nothing that forbids those life forms from looking very much like ourselves. In fact that is a very distinct possibility if they live on a world which is similar to our Earth.

    I think the assumption that we are alone in the universe is one of Incredible Arrogance. As Sagan said (I paraphrase) There are biliions and billions of stars and each one could have planets If only 1 percent of these planets can support life that still means Millions of worlds. And if our world can support life, why not another?. and that is assuming life as we know it.
    Not all who wander are lost... Some of us just misplaced our destination.

    I would rather be a superb meteor, every atom of me in magnificent glow, than a sleepy and permanent planet. The proper function of a man is to live, not to exist.

    If you subscribe to the idea of panspermia, I suppose it could be possible for life identical to ours to evolve on another planet in another galaxy. Perhaps whatever delivered us here also deposited our beginnings on another similar world. The odds would be incredibly slim. And even then, there's an incalculably small chance they would be identical to us.

    Still, the chance that we are alone in the universe is even smaller if you ask me.

    If you use the term "we". You are describing an incredable amount of consequences that arrived at our persent form. The chances that there would be an identical version of "us" that developed independently of "us" in another galaxy I think would be almost mathmatically imposibble. We are though, a great accumulation of designs that makes us what we are and are a great adaptaion to what "we" need to survive. The eye. Especially two for stereo scopic vision. But maybe 4 are better??? Two arms for opposed work and two legs for fast agile motivtion. Maybe sets of three is better??? I really think identicals is near impossible.
    Now, if you believe in "seeding" of the universe. That narrows it down considerably. The development of the speices would still have to do its adaptations to the existing environment of the local planet/area. But if "seeding" is considered, the basic DNA would have set programing that would/might drive certain features etc to a certain configuration. Although the new species would still be a product of its environment and could still be drastically different in form and function. If intellegence is possible in only one form, such as our brains use, then intellegence could be very similar and communications could be easier. I feel that although the chances are mathmatically high, that high number of those chances also make the configurations also too diverse to be possible. But I could be wrong 8^)

    Possible? Yes. Probable? No.

    Yes. A sound occurs whether someone hears it or not. Soud is defined as
    mechanical radiant energy that is transmitted by longitudinal pressure waves in a material medium (as air) and is the objective cause of hearing
    Although sound is he cause if hearing that doesn't mean that if there is nobody hearing it then there is no sound.

    See also Sound -- from Eric Weisstein's World of Physics

    Of course there are other definitions of sound such as
    a : a particular auditory impression :
    b : the sensation perceived by the sense of hearing
    etc. So it really depends on what definition you're using. I'm a physicist so I use the one found in a physics text.

    I think this is very much a philosophical question.
    I would argue that there is only a pressure wave - sound or noise only happens through perception by an observer, it is a subjective experience.

    If life is in the galaxy,
    and domed to be trapped on its planet or stellar system.
    Multiplication or size is a common problem.

    The sheer size of the universe leads me to believe there is intelligent life elsewhere. I'm no mathematician, but as someone mentioned earlier when quoting Sagan, even if only a small percentage of the vast number of stars in the universe were orbited by planets that could support life, that would still be a lot of planets that may contain life.

    Also, we generally tend to think that the only kind of intelligent life that may be 'out there' would be something similar to humans. Again, I'm no expert in this field, but we humans are as we are because of the way we have evolved to adapt and thrive in our environment. There may be planets out there totally unsuitable for sustaining humankind, that possess a number of other intelligent lifeforms who have adapted to thrive in their environment.

    As far as I can tell, life tends to 'find a way'. I recently watched a documentary on this very subject, and they discussed the presence of life in some kind of acid pits in Yellowstone National Park. Albeit primitive life, but life nonetheless.

    If some form of life can survive in one of the most hostile places on earth, why not then in the distant reaches of the galaxy? To sum up this post, yes, I believe there is intelligent life elsewhere in the universe. I do not however, believe it would be similar (let alone identical) to us.
    It is said that anticipation evokes happiness, so I say: look forward to every tomorrow.

    Stephen Gould famously talked about 'replaying the tape of life' and declaring it would turn out differently every time. Conway Morris, took the opposite tack and argued that intelligent lifeforms would be bipedal organisms, with principal sensory organisms and brain sat atop their body structure (i.e. they have heads). While I prefer the prose of Conway Morris I have to concede I'm somewhat with Gould on this one.

    When you do the math, life should be really abundend, Multi cellular life is rare, and intelligent life even more so. On average the order of size for intelligent life is about singular in galaxies. So, yeah, probably they do exist. They are just too far away for us. We have, just our little galaxy.
