Infinite Worlds: A Journey through Parallel Universes

  • Published on: 18 March 2015
  • The multiverse hypothesis, suggesting that our universe is but one of perhaps infinitely many, speaks to the very nature of reality. Join physicist Brian Greene, cosmologists Alan Guth and Andrei Linde, and philosopher Nick Bostrom as they discuss and debate this controversial implication of forefront research and explore its potential for redefining the cosmic order. Moderated by Robert Krulwich and featuring an original musical interlude, inspired by parallel worlds, by DJ Spooky.

    This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.

    The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

    Can you edit the title to just "a journey through parallel universes" ?There is absolutely no evidence of other worlds, let alone that they are infinitely many in number.

    During my short stint at M.I.T I had the good fortune of working with a Dr. that worked in a small lab located in the basement at Harvard and he proved to me the existence of a Parallel universe which was a lot like our universe but with small differences. He was able to prove how both universes vibrated at different frequencies which once he isolated the frequency of the other universe he was able to send/receive objects from the other side. Once he sent his lab partners car to the other side and never saw it again but did get a auto CD player in return. What made that so amazing was it was 1985 and our side hadn’t came out with CD players yet. The man had a 220 I.Q and was the most brilliant myopic S.O.B I’ve ever known.

    So the big bang is the father of all universes? I thought big bang produced our universe only. My question is. What contained the big bang it self? Was big bang in an empty space that contains all universes including big bang itself?

    It all makes sense now, can anyone else see it too?Look at the shape of a shell or any natural objects form. It's the cosmological constant pushing out.

    There much more theories of the universe creation than UNIVERSES and most likely all of them are wrong.

    Inflation doesn't have enough evidence for it to say that it actually occurred. It's more likely that our univers is all there is and the big "bang" wasn't a bang at all but rather a bounce.

    At -1:31:15 Mr. Green says and I quote .. "when things expand they cool off" .. lol .. really ?? Was that a mouse slip or should I say a lip slip.Is that even real science or pseudo theoretical scientism ?? coz things expand when heat is applied and they contract when cooled.Then Mr. Green comes up with "repulsive gravity suffusing space" and cheesy cheese analogies.. wtf ?? and that is science .. wowing the gullible, impressionable audience with repulsive pseudoscientific word saladry. Then he has a boring quintet of average musicians to qualify his quasi science. I've had enough, I'm outta here. It's the pseudo science circus, 50% of the bread n circuses programme.

    The confusion comes in when you keep comparing this particular Universe to the Big BangBut what About how many Galaxies that might Exists with Many Universes that seem to Exist in Circles - as too how do they relate to the Big Bang🤨But even deeper then that, How does the Different Dimensions fit into the Big Bang & Does the “Flower of Life” have anything to Do with how Reality becomes Fairy tales

    🙄It's "amazing" how these scientists in the 21st century 🍿are just now figuring out what the Ancients knew eons ago ... / what those of us from Generation X knew back in the 1970s and 80s from reading between the lines of what we used to call books 📚 handed to Us by an already back then orwellian staged up public school 🏫 system ... And don't get me wrong from the rolling of my eyes I don't dislike the presenter here I'm just irked that it took his colleagues and others as long as it did for them to get up to speed

    My problem with simulation hypothesis is that it doesn't seem to explain anything that we can't explain without it.

    I don't believe that we're in the simulated universe because if we were we wouldn't be able to influence our reality with focused thoughts and intention. Also I believe that Space is some kind of liquid and gravity is more like electromagnetism. QUESTION: Is thought faster than light?

    A small dense mass had all the mass in the universe ?Uhhhh, really ?Or are you saying the big bang energy was converted to mass as it cooled ?

    I have a difficult time accepting the size of the universe.It doesn't make sense.So, something is going on that is Matrix related.

  • Sekeeta Helia Straatmans

    How can anyone who theorises about Big Bang or Multiverse OMIT/LEAVE OUT the Spirit of the Thinker??? In other words, Thinking must generate everything and because it (thinking)(the Power of Living Light) has many abilities and is invisible-it doesn't make sense to try make a 'model'. Thats because we Live it. We are the individualising model...

    When you can't figure out how our universe works, just invent an infinite number of them.

    For anyone who believes this nonsense, that also means you now have the answer of how something comes out of nothing at all. Little quantum fluctuations dancing around. Btw, fluctuations of what

    Without even watching the video, the title of it suggests that it is science fiction that they will be talking about. Have they even seen one and where are they ? Science is standing on Shakey Ground these days
