The Fermi Paradox — Where Are All The Aliens? (1/2)

Kurzgesagt – In a Nutshell | October 11, 2025



The universe is unbelievably big – trillions of stars and even more planets. Soo… there just has to be life out there, right? But where is it? Why don’t we see any aliens? Where are they? And more importantly, what does this tell us about our own fate in this gigantic and scary universe?

    Have we tried not looking at everything through an exploitation lens like we do? Like is that even possible to be in harmony for Christ's sake? 100% certain that agent Smith was dead on in his speech and we are most certainly a virus I mean come on we're doing the exact same thing every time over and over and over again endlessly and those that disagree are either consumed themselves or absorbed. If you want to do a great video you should do one on, "planet Earth, a mass Stockholm syndrome phenomena"

    Dyson spheres have got to be the dumbest concept ever thought of like right up there with the concept of government, finances, religion, property ownership, crapping in the same place everyday, etc. like you would have to be walking into a wall retarded to think up some stupid crap like a Dyson sphere

    Maybe angels and demons, the kingdom of God and the kingdom of darkness, are both advanced civilizations from other worlds, interacting with us on earth.

    The responsibility of passing on life is in my opinion an artificial one—there’s no such inherent responsibility. If we deserve it, we’ll get there, and if we don’t, we won’t. We might even get there without deserving it..

    As for the Fermi paradox, I can’t agree that we’re so special as to be the only ones—that sounds very unlikely. The “complex cells” filter and the “intelligent life” filter seem to be better candidates for hard filters and perhaps a more acceptable explanation. That would make the probability high enough across the observable universe, but not so likely if we only consider our own galaxy

    If the next stage of mankind with conscience ( I do not mean Christian morality though without the base of it no conscience is possible) the fermi paradox is very likely.

    Oumuamua.

    3I/Atlas, now followed by a host of similar bodies, like a troop.

    Swan, about 100 times larger than 3I/Atlas.

    Transmissions from voyager spacecrafts.

    Signals that are a pattern.

    For all we know, the universe could be teeming with intelligent life, and we may be the only primitive , less intelligent form of life.

    Without Stars, there would be no Life.

    Therefore with Suns there may be Llife.

    Given the amount of Suns in the Universe, the obvious fact remains…..Without Suns, no Life and with Suns there may be Life.

    Anybody who says there is no Life or indeed, there is no intelligent Life in the Universe, other than here on Earth is ignorant.

    Really we are all ignorant as regards Life elsewhere in the Universe.

    But really, just look up to the Stars….

    Imagine people after ww2 decided to stop investing in weapons all together…. Imagine a world în witch the priorities are : human development (not more and stupid, but constant number and better life quality), environment; wild life protection; AI put in the use of bettering life, exclusion of corruption by eliminating full blood lines.
    Imagine a society that managed to put its priorities in line, eradicated diseases, ended suffering, invested in good science , and left…. And imagine being a member of that society…
    Would you keep in touch with us knowing how we are???
    Beings tend to not return to the bad place they evolved from…

    1.) Wir sind nicht die einzigen Lebensformen im Universum. Es gibt hundert tausende Planeten auf denen Leben enstanden ist.
    2.) Von diesen hundertausenden an Planeten haben tausende eine Zivilisation entwickelt
    3.) Ausnahmslos alle Zivlisationen sind untergegangen, weil alle irgendwann die zerstörerischen Kräfte der Wissenschaft entdeckt haben. Einige früher, einige später. Einige haben sich mit Industrialisierung zerstört, andere haben Kriege mit den schlimmsten vorstellbaren Waffen geführt. Alle haben sie sich am Ende selbst zerstört, auf die eine oder andere Art und Weise.
    4.) Die Menschheit wird das gleiche Schicksal ereilen. Ich bin nur gespannt, wie sie es genau machen. Entweder per nuklearem Holocaust, Zerstörung des eigenen Habitats durch Maßlosigkeit oder einfach durch ein mutiertes Virus, welches tödlich ist und Massen dahinrafft.
    5.) Es gibt zu viele Möglichkeiten, sich selbst zu zerstören, wenn man denn erstmal die Funktionalität des Universums genau erkannt hat
    6.) Die Erschaffung einer Zivilisation benötigt Milliarden von Jahren. Die Zerstörung schafft man in einem Jahr oder weniger.
    ergo
    7.) Das Universum ist fehlerhaft, so fehlerhaft, dass keine Zivilisation es jemald schafft, mehrere Planeten zu bevölkern.
    8.) Das ist reiner Zufall, niemand hat das Universum so designed.

    Before 1400AD , peoples in the america's didn't know about other peoples of the world ,and we know they were wrong . So just because we don't know of other aliens , doesn't mean we are the only life out of all other worlds . It's like a person saying others don't exsist because they are not important enough to exsist . Therefore this paradox is a false premise .
