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

  • Publicado em 5 Mai 2015
  • 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?

    Aliens don't come to earth because it has only one star reviews

  • NeverMeantToBuild

    Have you ever tried to speak to an ant? You could try as hard as you can use every bit of technology we have - we can currently travel into space but still can't talk to ants... my point is there's a great chance we just are so far behind we aren't getting the signal

    There is a possibility that since the universe is “young” in a certain sense and that the earth has existed for a third of it, we could be the “ancient aliens” that will be found millions or billions of years later

  • ShadoVerse

    Imagine someone on another planet seeing a similar space sci-fi vid about our and more planets.

    Kurzgesagt seriously couldn't go 5 minutes without being existentially horrifying

    It’s so fun to watch this at midnight and get an existential crisis while trying to go to sleep.

  • Charlotte Koskamp

    I always find it funny that people start looking for advanced civilizations. I think the chance is way bigger to find simple life forms than entire civilizations

  • David Lindsay Troffer

    Maybe there are technologically advanced civilizations out there, but they just don't care if there is other life "out there". That specific curiosity may be unique to humans.

  • Melodie Frances

    I also wonder if other life forms could be so drastically different from us that we wouldn't even recognize them as being alive. And that they are already here.

  • Just Some Guy With Bad Directions

    Imagine we’re the only civilisation that hasn’t passed the filter ahead and then like a couple billion planets see us as like the most undeveloped planets. We are pretty young for a planet so it is kinda funny.

  • OllieSutton

    I think whenever this question is asked, its normally by people who cant wrap their head around how big the universe actually is. The chances are that there is thousands of life forms, in ways we cant even imagine life would develop, but the chances of us ever finding it is incredibly slim

    These aliens are probably so advanced that they can’t bother with our primitive minds. It makes me sad I will never get to see the future of humanity. Will we evolve to be smarter? Will we kill each other? Or will we colonize the stars? I don’t know, I’ll just die here in the meme era.

  • Scott Wells

    It could just be a time overlap issue. I can imagine it being an extremely unlikely event that any intelligent species makes it past a million years of existence (especially when you consider what a teeny tiny amount of time that we’ve been here). But let’s say, for argument sake, that a million species last a million years in our immediate neighborhood. When placed randomly on the multi billion year timescale between when our universe was cool enough to host life and now the chances of overlap are still quite minuscule. So maybe the whole issue is just that no 2 species have ever been here at the same time.

    The Fermi paradox is by far one of the most interesting theories out there.

  • The Mr. Man

    "We are alone"

  • Jerry Salazar Ramos

    The Dune universe takes place 20,000 years into our future and involves thousands of planets being inhabited by us humans, yet no alien life is found. Not saying there is no alien life forms out there, I truly believe there are. I just love the different perspective Frank Herbert gives us with his Dune series. Humanity diverges over time into fundamentally different beings. Human beings by the time of Paul Atreides have been in space for over 20,000 years. Earth, old Earth, is so far into the past that it’s just a rumor, a fiction. To the lower-educated classes, they just simply accept that people have been in space forever. Just something to think about, nerd rant over, lol.

  • Mike Sargsyan

    In my personal opinion, what the paradox doesn't account for is the insanely large size of the universe. There can be millions of advanced civilizations traveling through their galaxies, however, the amount of galaxies being in the billions, it is quite possible to never meet them in our lifetimes. The paradox sophistiaces things by adding concepts like "the Great Filter" which, for example, can be avoided in different types of civilizations. The absurd size of the universe just makes such encounters highly unlikely.

    Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.
