    Finding alien life on a distant planet would be amazing news - or would it? If we are not the only intelligent life in the universe, this probably means our days are numbered and doom is certain.

    First of all , if we haven't found intelligent life , it doesn't mean that there is none ( over even few ) . But lets presume that .
    So basically speaking we must conclude that there is some great filter since we have not observed any signs of intelligent life , therefore if we get any sign of intelligent life we are probably behind that filter .
    But here's the problem , if we do discover outer space life , doesn't it mean that perhaps there is no such thing as a great filter to begin with ? ( since we "made up" the great filter concept based on lack of outer life )

    I think it's extremely stupid and arrogant of us to believe that in all the infinity of universe all kinds of life would need water to exist. There must be planets where they don't even know what water is. In others, water is probably as dangerous as fire to their lifeforms. Don't forget the universe is infinite and we only know about a few billion stars and planets. The possibilities are endless.

    *It's also possible we are living in a highly computerized matrix system that presents a "false reality", and that in some scope or form, there is another reality covered by the curtain of this one. Maybe that's the real thing where highly intelligent beings exist and they are somehow watching us from it, while we are living in this "fake show" of some sort. That would also mean that space isn't real nor are any other planets. Just a theory, not saying it's right!*

    I think that we don't find E.T. life because it don't want to be find : just by studying the human behavior, the wars, genocides etc...they would surely be afraid of us and make everything they can to avoid our contact.
    From this, two options are possible : 1) If they think like us, they could try to kill us to avoid any danger from us, so it might be our "great filter" in the future. (We can even think that the dinosaurs were intelligent enough to be fearful and have being destroyed by E.T.s ;) ) 2) They have musch more good morality and empathy than us, so even if they are afraid by us, they won't try to destroy us (unitl we became too powerful maybe?).
    A third possibility is that all the intelligent lifes have already emerged and achieved discovering technologies to travel outside our universe, because thay saw that it would be one day unlivable.
    This subject is very interesting because almost all hypothesis can be true, and there is a lot of hypothesis if we have imagination.
    What are yours?

    The way I see it the only reason alien lifeforms haven't interacted with the planet is because there's no reason to. Humans are unintelligent creatures that live towards self destruction. Slowly killing themselves off for luxuries. In the aliens of a potentially highly intelligent species what good would come from landing here? We're useless and we probably don't even hold a fraction of the capabilities they do. We wouldn't be good for war, we wouldn't be good as slaves because we're so inefficient. It's truly like what do we have to offer a species tens to hundreds of times more intelligent than us? The way I say it, ants to us is us to an alien. It's like...I could squash you but what would I truly gain?

    Or the great filter is.....the speed of light can not be over come. Hard to spread out when you can't spread to all corners because of the ginormous distances. We've only been broadcasting radio waves into space for what 80 years? The Milky way is 100,000 light years across. So the majority of the space inside the milky way galaxy isn't aware of our presence.

    this video doesn't take into account the vastness of space and that it takes light huge amounts of time to go from place to place. our own radio broadcasts have only traveled 80 light years or so. also it is unlikely that aliens would use or rely on such dated tech. for all we know alien transmissions are all around us and we simply don't have the tech to hear them.

    Becoming the dominant life form does not mean that dominant life form is intelligent. It merely means that dominant life form is better than the other life forms around to such a degree that the other life forms cannot stop it. Dinosaurs are the classic example. They were the dominant life forms. No doubt about that. However, because they were strong, nothing could stop them, and they dominated for 100s of millions of years. The galaxy may very well be filled with planets populated by extremely strong, resilient animals that do not need intelligence to achieve and retain their dominance.

    The mere fact a universal dilemma is looked into from a galactic scale makes your assumption seriously flawed. What if intelligent species (as in interstellar species) were only present in the ratio of one per single galaxy, on average? Or one every ten galaxies, or per galactic cluster, for all that matters. That would still mean there's potentially billions of them throughout the universe. There, I've just proven your conclusions completely wrong. Also remember, the pretension to make final statements is what gave birth to religions, while we're supposed to be men of science here.

  • dantopper123
    dantopper123 5 days ago

    Ok one thing i dont understand is this, why would anyone assume that if alien life did come to earth that its for malicious purpose? Just like the human race having its "good" and "bad" im sure there is just as much diversity in other possible intergalactic civilizations. Independence day and other alien overlord movies may not be so accurate and science fiction only pointing to evil aliens destroying earth. There are literally thousands if not millions of other solar systems in the galaxy. For something to travel billions of light years just for the singular purpose to annihilate us does seem a little farfetched. But we wont truly know the intent of any alien civilization untill that day comes. Either they teach us to thrive and advance us or they enslave us and harvest what little resources we have left. We are running out gradually using up everything and destroying ourselves. We dont need to think an advanced race would do it. Most likely they are laughing at us.

  • Gustav Bertlin
    Gustav Bertlin 6 days ago

    It’s a pretty interesting theory I gotta say. But I can’t really understand why the fact that we haven’t seen space empires would back up this theory. Just the fact that it was 3 years ago we first detected planets around the closest star to the sun which is only 4ly away, that says quite a lot. What would we expect to see? A Dyson sphere that’s probably not even possible? Even if there was intelligent space empires out there, how would we possibly even detect them? Making a conclusion that space is dead is just ridiculous when we have no way of detecting life.

    Well shit... That just made me feel depressed and cynical. Science and reality can really be a bummer sometimes. Hopefully, we are rare enough that our future isn't certain, but not rare enough that we are the only species that has made it this far. It would be nice to know we aren't the only living planet in the galaxy, or even the universe (which seems unlikely). Because it makes it that much more screwed up when you look at how we treat our planet.

    in 1990,s people discovered alien signal,this signal was modern like one that we could send right now,but,this signal was as thinked send by even a lot of billions years,some people think that's ice ages,but some that's a lot before send.
    As scientists say this signal is about help,surely about nuclear catasthropy or a specific mostly likely natural disaster that we don't even have right now to be avaible,they didn't knew there are others civilazations in the universe,thinks like ours,and that's pretty strange,for me opnion is MAYBE.
