How do you know you’re a person who has lived your life, rather than a just-formed brain full of artificial memories, momentarily hallucinating a reality that doesn’t actually exist? That may sound absurd, but it’s kept several generations of top cosmologists up at night. They call it: the Boltzmann brain paradox. Fabio Pacucci explores this mind-numbing thought experiment.

Lesson by Fabio Pacucci, directed by Skirmanta Jakaitė, Art Shot.

    If you’re looking for an inventive thriller to read, we highly recommend Stuart Turton’s book “The 7 1/2 Deaths of Evelyn Hardcastle." Download a free audiobook version here: www.audible.com/ted-ed
  • @sanskar_vyas
    The animation and character design in this one was uniquely good
  • @lias934
    A beautiful Paradox- "The brain uses itself to understand itself"
  • @Bob.ross22
    When I was younger I had a thought a bit like this. I didn’t know about entropy and the eventual heat death of the universe and thought that time was infinite. In that case, wouldn’t every single possible scenario that could ever be imagined and all variations of them inevitably come true by the nature of infinity? For example, in the far future there will be an identical video made on a planet identical to Earth and a commenter with an identical life to mine will have made this comment, except the comment would end in a period
  • @lordsiomai
    The way this channel casually drops existential crises in me. Beautiful stuff!
  • @jessical4866
    Boltzmann’s logic of entropy to statistics to infinite universe - and the way TedEd illustrated it - gave me so much serotonin.
  • @HarperBizzare
    Kurzgesagt: I'm your only source of existential crisis. Ted ED: Hold my beer.
  • @Ubrzani
    As a long-time (more or less) TED-Ed follower, this is the first episod which broke my brain! 🤯Also, yet another impeccable animation! 👏
  • Thank you TED for putting my continuing existential crisis into words, such that more can experience it.
  • @ezrankala
    Now we are talking, This is the content I crave for! Boltzman ... what a guy Thanks TED!
  • @JDG-hq8gy
    It’s impossible to calculate the probability that we’re a Boltzmann brain because we’re using laws of thermodynamics, quantum physics, etc. that we could’ve just imagined
  • I’ve been very interested in The Boltzmann Brain hypothesis recently and this is just wonderful.
  • @MrKohlenstoff
    It would be so ironic if a Boltzmann brain randomly formed, hallucinating the experience of this exact video explaining the brain's own nature.
  • @the_otter5936
    This is really interesting! I'd heard about the Boltzman brain, but I'd never considered it much. I was quite creeped out when you mentioned how much more likely it is than a real universe.
  • The artistry in this video makes an already enriching and super-interesting topic a beautiful experience to watch. Thank you for posting.
  • @CassBlast5
    Whoever did the art for this should be commended; it's awesome
  • @jvb5590
    I applaud the animator hired for this video - exquisite interpretations of Boltzmann's thinking.
  • @_aidid
    I have had such paradoxical thoughts since my teenage years, but I never thought that other people have this too 🧐
