Elon Musk Shocks Scientists with His Knowledge of Extraterrestrial life

 elon musk had a very interesting    conversation about aliens    and as he analyzed with this rate of    development in a few hundred years we    will be able to basically bicycle on    other planets    and after a few thousand years we will    be able to easily visit other galaxies    but our civilization hasn't lived that    long if we compare it to how long earth    or other planets exist    if we look at other planets other    galaxies and analyze how long habitable    planets exist that can have life    it begs the question    why we haven't seen any signs of aliens    where are they    this is a fermi paradox    but fascinatingly enough there are    answers to these questions    and these answers are exciting and    terrifying at the same time    with that elon musk proposes his own    solution to the fermi paradox and    whether aliens exist anywhere or not    we have a fascinating story today so    let's start from the beginning    plenty of time has passed by now for    extraterrestrial visitors to have come    given us a visit    and they haven't    which means that an easy conclusion we    can draw from it is that there are no    aliens    but is that the only conclusion which    can be drawn from it    well spacex ceo and rabid fanboy of    space travel elon musk seems to think    that it is a very complicated puzzle to    solve    as elon said fermi paradox is one of the    toughest questions in philosophy    one of the disturbing implications that    has been brought up as a solution to the    fermi paradox is the possibility that    intelligent life wipes itself out before    it can reach the technological point of    space travel to other planets    such as by depleting their planet's    resources nuclear weapons or climate    change    and musk theorizes that this is why    multi-planetary travel and ultimately    colonization is so important    with our planet's current challenges we    might be on our way to destroying    ourselves before reaching    multi-planetary travel    this is what musk calls the great filter    and it is why he is so dedicated to not    only space travel but the idea of    colonizing mars as a backup for humanity    if we are indeed the only intelligent    species in the cosmos and we destroy    ourselves through nuclear war or earth    is destroyed by vested interest in    fossil fuels slowing down the process    towards renewable energy then that    doesn't just kill humans but destroys    the only intelligent life in the galaxy    and elon thinks that we shouldn't stop    searching for an alien life at all    as he tweeted it would be amazing to    encounter an alien civilization provided    it is not their invasion fleet    another tweet musk posted on his twitter    contains a study from gizmodo which has    different solutions to the fermi paradox    with different explanations as to why we    haven't had a visit from any    extraterrestrial life yet aside from the    depressing possibility that they all    blew themselves up    therefore there are very interesting but    at the same time the creepiest reasons    aliens haven't come to say hello    first of all very popular theory is that    they've been watching us like zoo    animals    this one sounds like a conspiracy theory    or science fiction but it has been    theorized that aliens may have been    around us the whole time    and have been watching us in our natural    environment the whole time    out of different theories that try to    solve the fermi paradox this is the one    that elon musk agrees with but this    argument was first proposed in 1973 by    john ball and regardless of whether    they're watching us for entertainment as    suggested by south park a while ago or    studying us for scientific reasons out    in space watching from afar or hidden    amongst us on earth    this theory says the reason we haven't    seen aliens is that they don't want to    be seen    and at the world government summit this    argument was expanded by elon musk who    said that if there are super intelligent    aliens out there in space    probably they're already observing us    and we just are not smart enough to    realize it    any advanced alien civilization that was    at all interested in populating the    galaxy even without exceeding the speed    of light could populate the entire    galaxy maybe in 20 million years max so    that is quite likely    one more suggestion relating to aliens    secretly being around us is that they    have in fact been trying to contact us    for years but we haven't got the    technology to receive their messages    stephen webb has claimed that there are    many avenues they might have been using    to try and contact us including particle    signals tachyon signals electromagnetic    signals gravitational signals or    something outside the realms of physics    or our imaginations    for those of you excited at the prospect    of aliens like muskies there is hope    that one day we might develop the    technology to realize how many of their    calls we have missed    one more solution to the fermi paradox    is a celestial version of that one scene    from indiana jones with both us and the    aliens waiting in different metaphorical    rooms for the other to break the silence    first there have been points made by    both david grin and michael miesha that    attempting to transmit a call out to    space to contact aliens might draw    dangerous attention to us prematurely    which at the very least is a policy    issue if theoretically other alien    species decided to do the same    then what do we get    everyone listening but no one's speaking    with that    it might be strange that aliens might    have no interest in leaving their home    planet    the concept of dyson spheres large    structures that encase stars or perhaps    entire galaxies    might mean that aliens may have built    their own entertainment to keep them    occupied which has kept them from    exploring the universe in other words    they exist    we just haven't seen them because    they've not bothered to leave their    planet    also a unique proposal was made by milan    m kirkovich and robert bradbury which is    that many intelligent alien species tend    to become more machine based    with large supercomputers that produce a    lot of waste heat    as such they aren't looking for the    comparably quite hot areas which    biological life needs    but instead cooler areas which make    getting rid of waste heat easier    according to this theory that would take    any space travelling species out to the    outer rims of the galaxy    rather than anywhere near us    that means they're out there but just    not near us    this is a reasonable explanation but has    been argued against by other academics    by now    stephen wolfram has suggested that    he-free computing may be in the cards    for our future    so presumably if we can make it so can    intelligent life    that blows a irreparable hole in that    solution to the fermi paradox    another explanation is that just like    the theory that they're waiting for us    to contact them first because they're    worried about drawing attention to    themselves there's also the theory that    most of the aliens have their own    equivalence of ridley scott alien or h.g    wells the war of the worlds and have    decided not to travel at all due to the    perceived risk of traveling in space    after all they cannot guarantee the    humans their meat are going to be any    more friendly than we can guarantee the    aliens we will meet will be    that isn't even to mention the other    risks about sending members of their    species out for long distances in space    in the light of everything terrifying we    know lurks in the place where no one can    hear you scream it makes sense for    anyone alien or not to look at the    concept of space travel and decide to    stay home    truly intelligent life indeed    all in all musk believes that to escape    the great filter of destruction of    humanity by humanity    we need to begin colonizing mars and    other planets whilst we have the chance    especially if we are in fact the only    intelligent life in the galaxy    but for sci-fi fans who may be    disappointed by the low odds be    comforted by the concept that there are    a number of different reasons as to why    we haven't made contact with aliens yet    and just because the odds are low it    doesn't mean that it can't happen    don't forget to subscribe
