Infinite Worlds: A Journey through Parallel Universes
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.

I'm very interested.
What about the thing holding the multiverse like the omiverse
Rudy Burdick looks like you are ready to translate for donald trump.
Russian scientist don't seem to be nerds at all. Or maybe they are just so manly that even their nerds aren't nerds to us.
The most fascinating part is realizing the universe has spawned creatures capable of understanding it. The graph matching the predicted observations is indeed amazing. We are the universe's way of understanding itself.
Yes , imagine a group of atoms collecting themselves to understand wtf is going on 😀
The most fascinating thing is there are both, even a spectrum, of people capable of being aware of a universe or aything outside what they know for sure.
We are the imperfect representation of a higher more perfect universe Pythagoras

Welcome to the realisation mentioned in the last line.
What makes these people so amazing is not necessarily their incredible mind but rather their humbleness.
definitely both! :-)

In the pursuit of the truth of the nature of our reality, one must first face the reality that our we don't know everything, so we should be open to anything.
Carlos Hernandez I'm open to you not knowing a god damn thing you are talking about, are you open to that possibility?
He's speaking of God in a figurative sense, no a being. Same as Einstein did.
Truly exceptional. It makes you think how small and insignificant we are yet the potential is unlimited. Loved the sense of humor too.
Outstanding. Brian Greene explains things so clearly. As far as the multi verse theory goes, made a believer out of me. Thanks Brian.
Infinity, might be, from a Logical Verifiable Scientific reality, impossible to prove, or verify. After all, there can be no end to that verification process. Recently, in Quanta Magazine, I have read that Mathematicians now, instead, use an Alternate Phrase, "Big Numbers Sets", and they also figured out that using smaller limited sections, from "Big Number Sers" allows their Super Computers to render "Patterns Within Those "Smaller Sections" from "Big Number Sets"! How many "Super Computers" can You Afford to melt down in an unlimited numbers row? Always retreat back to your imaginations, and keep attempting to find "The Way"!
Without proof? This is getting familiar and I can't quite put my.....Hail Mary full of...
I just love listening to Brian; not only is the subject fascinating, but he sounds so idk, excited about sharing it - and so clear. Much like Sagan, Nye, Dawkins, Tyson and Krauss, their lectures are absolutely riveting.
Raubhautz I'm riveted
BRIAN'S THE BEST ONE THERE... ALAN SEEMS A BIT COOL
Nye shouldn't even be in this conversation...
Nye neither tyson , talk about over inflated egos
Please do not include Bill Nye with the likes of Carl Sagan, Richard Dawkins, Neil Degrasse-Tyson please. He doesn't deserve to be mentioned in the same paragraph as those great thinkers. Bill Nye is a hack.
An infinite universe or multiverse may seem weird or too difficult to comprehend, but when you think about it, a finite universe or reality is perhaps even more weird. Either way, I'd say the true nature of reality is truly weird!!!
Yeah, nice to think that we are an alien simulation wich creates random worlds when "Jonny" spams "create" button in science class...
@@artopiiparinen1778 yours is far closer than the premise here. MWI is actually dead in the water and pretty much nonsense, but great for comics. what's far more fascinating is the holographic theory where the information is encoded in VAST 2-D branes.. but they are separate and unique realms (and not that many, perhaps 7 for the Bulk). when a NDExperiencer or Sage pierces the veils they can see them realms. but they are definitely NOT alternative timelines
I can't see there being a single or even a multiple reality,and with individual people their reality is certainly different than mine and yours simply because we do not exist in a certain time nor place,but rather a realm that is lost in a vast expanse in which our lives are played out forever. It's easy for me to say that at the moment of death we are reborn to life,as I believe we are a conscience awareness of our God.
Look up the definition of simulation
@@artopiiparinen1778 Look up the definition simulation
Thanks for top notch wisdom of our era, for free - and without commercials! Brian Greene really did something for mankind organizing the festival and uploading to UT free of charges. To this particular part, I do not know how Andri Linde is doing it, but he can really be funny.
What Einstein did in General Relativity, in a nutshell is this: Gravity had been measured assuming space and time were constant. Doing that led to the conclusion that gravity was a force, which it could be, but then it would be a completely unique force and quite mysterious. So Einstein let space and time be a variables instead of constants. He eliminated gravity as a force but that still allowed celestial bodies to have their momentums and move in circles, etc. His reformulation also allowed, but he didn't see it at first, for an expanding universe instead of one that contracted. The contracting universe idea was based on thinking of gravity as a force. I'm not sure, but I think Einstein had at one time claimed that the universe was static in size and thought all the celestial motions would just go on forever, except of course he knew suns would bow up or burn out, but other than that, same forever. Note that QED (quantum electro-dynamics) rejects general theory of relativity and posits a gravity as a force mediated by a flow of graviton particles, though none has ever detected such a particle and at this point, 2017, it seems unlikely such a particle will be detected. Both theories can explain the motion of celestial bodies. Multiverses don't explain anything, but they merely guess that hard to explain phenomenon, like black holes or dark matter, arise when the properties of our universe just happen to interact with the mostly different properties of another universe, the various universes generally not interacting much at all. Interaction can only occur within a framework of similar properties that allow for interaction. BTW, way back in 1789 Immanuel Kant ( in Critique of Pure Reason) had an inkling that human reason might be lacking, but he noted, that if it is we'll never know....except in cases that reasoning seems unable to produce satisfactory explanations and two or more explanations seem equally plausible. Such situations would imply something else is afoot, but we will not be able to describe it within the limits of reason, and thus would not be able to describe it or explore it at all.
My amusement was that scientists often speak on another level, and some of the guests in the panel knew this, leaving others to over explain for the event. I sensed a bit of uncomfortable silence, and a bit of figiting, as the Russian physicist went over the average viewer ( or audience's) head
Gotta love Brian Greene, the way he translates cosmology to people in general but he inspires colleagues also to visualize concepts consistent with the equations. Einstein imagined his ideas first then worked it later. "Imagination is more important than knowledge. For knowledge is limited to all we know and understand, while imagination embraces the entire world, and all there ever will be to know and understand".
BRIAN'S THE BEST ONE THERE... ALAN SEEMS A BIT COOL
The more of these that I watch, the more I learn that we know next to nothing at all about reality.
I agree this host should listen and not interrupt so much he cut in often and with disregard. Having said this it is a fantastic and stimulating series. Love it.
I ❤️ professor Greene for creating such a great institution.
I'd like to hear them complete their explanations without interference.
If it weren't for Brian moderating, you would realize just how mind numbing the science can get

I can co relate with this video very much as my religious books like Vedas, Upanishads, Mahabharat, Bhagwad Geeta, Puranas are filled with such stories, realities and concepts. It's great to know that these scientists are also attuned with the spiritual side of these concepts. It is a wish to work under these great physicists.
I am not a bible thumper but was incouraged to read it and if read carefully many people in the bible also discribed being moved to another dimension or reality as well. but I will definately look into these other regigions as welll
Man, I can't get enough of Brian Greene. It has been 8 years since this video was uploaded. 19 year old me binging on all of his videos. He's got to be one of the bests, if not, the best around here. So humble, so humorous, so soothing. I kinda have a man crush on him😅
When minds like this get together, it's so refreshing to be presented with geniuses taking the mickey out of themselves with their tongue in cheek humor. Theses are minds who appreciate the magnitude of the subject and yet have the innocent childlike prankster attitude to make it palatable and pleasurable for the rest of us. Cool!
One of the most interesting and entertaining presentations on YT. I wish I had been there. Even more, I wish this same group could come together again and rehash this based on all the new information we have gained since 2009.
To have the same group together again in 2021 would be very interesting !!!

I must have watched this 20 times or more. I’v never heard this explained so beautifully before.
Brian Greene: a man who found his true calling.
We are just a grain of sand in this vast infinite conscious universe, & yet we are part of everything. We are not alone. I've encountered what i called Galactic civilization on my one Out of body experiences, they are more advanced, time is irrelevant there. I can sense there's life there, but i was pushed away because i carry fear on my Consiousness & that place only radiates on love, peace, abundance, oneness, compassion. The pineal gland is the portal to another dimensions / realm of collective source of consciousness! Meditate, stay at peace, stay on oneness, stay on love. To this day I'm still shock on what I've seen, that when i came back in my physical body, it feels like this life is a dream. A very sacred dream, that our existence on earth is nothing but an brief instant. Physical body dies, Consiousness transitions.💕
and just how relentlessly charming is Brian Greene
I already know what they are going to say,i've watched them talk so many times about this BUT:Never gets old
Between you and all your doubles in parallel universes where the same video (or something very similar) exists, you all have probably watched it billions of time through. 😊
Interestingly in old scriptures from hindu philosophy also in line with Multiverse. We are now reinventing in different manner. But arguments are so lovely that it never gets old.
I just discovered this channel today and my god do I feel gypped by life for not discovering it sooner. The most fascinating topics to me.
Dr Greene, you must be the most talented presenter of complex ideas in an approachable way. Thank you for making cutting edge science something I can now include in my own outlook, very much appreciated.
Brian Greene is so interesting, and Andrei Linde is so fun, I love these talks.
This was absolutely worth it just for Andrei’s sense of humor. That finance joke at the end has me crying laughing right now.
This is the funniest bunch of physicists so far. I love that they can crack a joke while talking about serious stuff like cosmology 😄 I also like that the guy asking the questions, is asking all the questions I want to hear. And the mic drop at the end deserves an applause
"THATS WHY ITS BLUE" 💙
What is blue?
That was truly the highest point answer.
After watching this video and then researching REM sleep patterns, I have concluded that when we dream, we get a glimpse into a parallel universe where there is an energy akin to our own.
Wow. Great. Real scientific.
For fuck sake
BEAUTIFUL, JUSS BEAUTIFUL🤩🌟. THANX TO THE WORLD SCIENCE FESTIVAL WE ARE EMPOWERED WITH CURIOSITY❤
i don't know why many people dislike the host so much. as a non cosmo scientist person, i feel.the host, hes presenting common people with their common understanding
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.
He was once Steward of Gondor, I believe.

I've spend an entire day binging on science lectures and these meet ups. The universe is a wonderful mystery!
Time well spent my girl! :)
Just life itself and the universe is so amazing I honestly can’t get my head around it and for our universe to maybe many of a million?!! If this doesn’t make you appreciate to be alive then you better start taking life for granted bc for all this to happen either on purpose or a random we are lucky to be alive and be intelligent life forms! I love science but I’m fascinated with everything beyond the stars. ⭐️
My God that Russian scientist is charming as hell! Mr. Linde, you are my new favorite.
Panties sopping wet...I feel ya
@@TheMillieSmallsNo, not like that. 😂 Ew.
This would explain the ridiculous odds of us being here in the first place. If there is a multiverse every possible outcome would probably come true, giving that there’s so many pocket universes, some multiverse bubbles could have different physics then ours, so it would make it more plausible for us to exist like do with the odds stacked against us of being here in the first place, because in lots of other multiverse bubbles there might not be life but in others there will be life, so with all that in mind maybe that’s why we can’t find aliens, because we are the only aliens/intelligent life in our pocket universe! It’s a mind blowing hypothesis but it does make a bit of sense how we came to be in the first place giving that if you changed the the laws of physics ever so slightly, we wouldn’t be here today. I love this discussion and it was so enjoyable to watch, it was very informative and funny at the same time.
It may make sense to you but it offers no proof whatsoever.
Never tired of watching again and again and putting mental efforts to understand you guys
His interjections are more like interruptions, at first it was wholesome. By the end you just dont want him to talk.
They’re all like this. So annoying

They should just have Brian Greene translate after each speaker speaks. Like college professors, there's no denying they are really smart and know what they're talking about - they just have trouble explaining things to people who arent in their field and dont already understand what they are trying to say.
Scorch428 absolutely agree!
Everybody but but Nick Bostrom
Brian Greene should just host all of these.
Can we propose this? Imagine an infinite multiverse that has no beginning and has been expanding forever and will continue to expand forever. Thus giving rise to an infinite number of universes at any point in the multiverse's evolution because, no matter how far back we go, we can always go back infinitely further so the multiverse has already expanded for infinity and therefore spawned an infinite number of universes (and that number will continue to grow even though it's already infinite). As soon as infinity is allowed to roam free things seem to get really weird. Now ... could you describe all of that insane and infinite complexity in nothing more than all the infinite numbers between zero and one? Maybe all of that insane, infinite complexity is no more profound than all the infinite numbers between zero and one and the multiverse is insanely trivial :)) It blows my mind to think that, as infinity is introduced it almost trivialises endless complexity and blows anything sane out of the water. If you can wield infinity then you are a Master of the Universe (and who wields the wielders? [He Man holds aloft his sword, I hold aloft He Man]). There could well be an infinite number of universes! I wonder if there is some kind of exclusion principle? So the multiverse does not bother to create an infinite number of exactly identical universes. An infinite number of "mes" typing this exact same comment into KZhead. And that infinity is a trivial infinitesimal in the grand cacophony. Perhaps the multiverse is rigged so that it doesn't bother with exact copies or maybe it simply doesn't care and everything exists including infinite copies and infinite copies with one sub atomic particle in a slightly different state and ... so on. What are the philosophical ramifications of this? If we've already got an infinite number of universe that have already been created and yet we're constantly expanding and creating more isn't that leading to a paradox? We've already created everything so how can we carry on creating? The multiverse contains itself? An infinite regression. Is there some kind of moronic banality in all of this? (Sorry multiverse, please don't destroy me just yet) And anyone that denies the allowance of an infinite multiverse or is uncomfortable with it will need to answer the question; well what got the multiverse started? What is the multiverse contained in? And then, "what contains that?" and so on, back to our god - infinity. I'll carry on watching these. Awesome pub conversation to have down at "The End of Time". Certainly won't get you laid though. Women tend to switch off when you start talking about science shit :))
That musical interlude though :)) Pretentious cheese
Science takes just as much blind faith to believe in as the many religions do, doesn't it?
No, because science works to predict, test and falsify theory, whereas religion simply swallow whole whatever the priest puts on the plate.
John von Horn Not me, love a good conversation about physics, the cosmos and quantum mechanics to the point it becomes philosophy or time to call a cab cos even the designated driver only abstained in every other universe...
Lucille de Lorme ~ Splendid attitude. I watch these wonderful talks while my wife is working in the garden and then try to explain them to her during our long evening walks and she listens patiently and just like the best of us can only mutter - wow.
OMG this is fantastic great talk Brian and Andrei
The interviewer rejects these theories because of a grandiose sense of self-worth. Ego is his biggest barrier to broadening his understanding.
Rookie Collins ego is much more destructive than that in all aspects of our lives.
Rookie Collins I think he does that, so they will explain better
He's not rejecting the theories moron. Robert is a stand in for an audience that may not be versed in the subject and asks questions to get more elaborate or consice answers. You really have no idea how these panel discussions operate. He hosts a Radio Lab. He 100% understands this science better than you.

Nerd girl
The rubber sheet example is very nice and intuitive. But it has one substantial flaw: It reduces reality to two dimensions. Reality has 3 spacial and (according to Einstein) one time dimension. But let's focus on the main problem with the rubber sheet: You drop a massive object (like a sun) onto that 2-dimensional sheet. The fact that it "falls" and ends up in a ditch is the result of gravity! So we explain something with the "force" of gravity - exactly what we intend to explain. Now we add a few planets and show that they orbit around that sun. For that purpose we now need two forces: Gravity and kinetic energy. Gravity exists already, so we need to push that second ball sideways to make it orbit (for a while). Unless we apply the exactly needed amount of kinetic force (push), it will either collide with the sun after a few orbits or be flinged out to space immediately. We also ignore the resisting force of friction. Now lets make that rubber sheet 3-dimensional. How? Suddenly we have no more force of gravity pushing our sun down into the sheet. And the planets now follow .... hmmm ..... lines around the sun. And each planet's size determines how those "gravity lines" are shaped and bent? How does that work in three dimensions, where the sun is not pushed down into a sheet by a "gravity" existing outside the system? Multiverse and strings are just following a human need: To slice massive sizes and complex realities into smaller "understandable" pieces. Math on top of all is denying that the reality is "infinity". Besides: Your joke about "Beta and Gamma" is nice, but inaccurate. His name is George Gamov. That's exactly why I always warn to change personal names in spelling as well as mispronouncing names. It leads to serious mistakes (not only jokes). Since some languages use different signs - this problem becomes even harder.
Great explanation of how objects curve space. Haven't been able to get my head around that notion before then. Great talk!
Sounds like a good explanation for at least some forms of paranormal activity. Furthermore it looks like there are plenty of possibilities for consciousness to carry on after the physical (physical to us here) has ceased. Rarther than oblivion.
THANK YOU for enlightening our consciences and minds. Always very instructive, human and respectful !
but the music resolved itself multiple times as opposed to the lecture. very nice.
How things have changed! Alan Guth was ridiculed for his study about string theory. And now he is celebrated and acknowledge.
Arubagyal gyal good point about Alan Guth and others which is why even thou I am tempted to make fun of all of this I try and keep an open mind and my mouth shut.string theory may turn out to be a dead end but some pretty smart people think there is something to it.
sorry but String theory can exist quite happily with 10 dimensions and certainly doesn't lead to MWIs
Where is the god Factor
loved that russian scientist, so fun :D
A great phycisict too :)
Andrei Linde is so funny! This talk was engaging and enriching like all other WSF talks I’ve seen. I can’t wait to go in-person one day. Thanks Brian Greene and WSF!
from a simpleton point of view, the big bang developed from a black hole that simply got too massive/big. So much matter got pulled together from gravity, that eventually it couldn't be held together anymore and the straw broke the camel's back. Gr8! Peace ☮💜Love I love Brian, and the comedy of the others. I remember reading Guth's expansion paper back in the 90's, and it changed me. These are giants of the subject. Please note too: If you read the term "many worlds", it is not the topic they're discussing here. The term is a name for a way to calculate numbers in quantum theory and is not describing actual reality of worlds. I've noticed this confusion lately in a lot of talks on the internet, and it leads to goblins and unicorns and fairy type of fantasy tallk.
Excellent & fascinating video, but could do without the moderator Robert Krulwich!!
Initially, I was at odds with the moderator. However crazy, he contributed in some substantially positive way. Ultimately, the panelist were able to maintain composure and approach his absurdity appropriately. I learned a lot, and now I know why I'll never study finance.
The ending statements of andre linde is profound, humorous, and poetic.
Great panel. Five dudes at the top of their game.
I listen to these talks when going to sleep. As i am a lucid dreamer I have he most excellent nights 👍🤙
The Allegory of the Cave.... Most people who are not used to new concepts or even new views on old concepts tend to see the "what if's" and "possibilities of the unknown" as fantasy, make-believe, or absolute science fiction... Those who leave the cave... Or even release themselves from the wall and look a different direction... These are the innovators, the artists, novelists and dreamers that build our world. We need more of them... 🤔
OMG, that closing line was absolutely hilarious. You gotta listen all the way.
Multiverse ! Nice to know, wonderful to observe. Now, can we just get along here on own little "bubble" ? Or are we going to fight and argue until we burst this beautiful bubble and scatter the particles into nothingness ? All our worries & questions never to be resolved......
I love these discussion topics. I just wish Brian Greene would moderate every one of them. Each time they have a journalist moderate them the person feels that they have to be a comedian and continually interrupt these brilliant panelist with their stupid jokes. Why? How many of us tune in to these science videos to hear a comedy act?
It did give a silly atmosphere to a serious subject. Almost mocking, in fact. Not all journalists are that flippant when moderating. Some are well versed science writers, others... aren't. "Let the guest finish his thought" comes to mind here though.
What Hubble didn't realize is that a number of conditions can cause objects to red shift, not just moving away. And some objects moving away aren't red shifted at all. Physicist Wal Thornhill has done a good job of both documenting and explaining this. Everything that exists as matter is electro-magnetic by nature. EVERYTHING.
Neutrinos aren't electromagnetic. Neither is Higgs field. Neither are Higgs bosons, or light wouldn't be able to move unrestricted. Neither are gravitons, or gravity would be attracted and repelled by lightning. (Earth gravity doesn't fall apart in solar storms). Neither is Dark Matter, which doesn't absorb or reflect photons at all. ...and that's just the stuff we know about. So no, evidence does not support an "electro-universe" or whatever easy answer they're pitching folks these days. New ideas are great, but not every single one is equal.
Love the live music that went on way longer than expected. Great work.
People have a hard time accepting these theories just as they did accepting that the earth was round and that there were other continents, just as they had a hard time accepting that slavery was wrong, and having sex outside marriage didn't mean that you were going to be burnt forever and ever and ever with fiery torments. Isn't is great to know that people are finally starting to move away from the ancient ideas about God and are embracing agnosticism, atheism, and a more kinder understanding of spirituality? I knew you'd agree....
So let me ask this: When scientists talk about the universe expanding, is it the underlying substrate, our pocket of space known as "the observable universe", both, or something else? I think what is confusing me the most is that between Andrei's visual and Brian's visual it seems like there may be a subtle difference in representation. Put simply: Do these multiple universes have definite boundaries like soap bubbles or holes in Swiss cheese? Or, are the boundaries merely there to draw distinction between one pocket of space and another, like boundaries on a map? **Edit: I found an answer to my first question, plus I finished the rest of the video. I think Robert Krulwich was not the best choice to head this forum, or at least he could've saved his grievances until the end.(Brian Greene seemed visibly peeved by the end.) Andrei Linde was hilarious though.

Curious did it do the stutter pause thing when you watched this

I see multi universe me in my dreams
I already know what they are going to say,i've watched them talk so many times about this BUT:Never gets old
So do I
Minor mistake in the conversation: 10 to the power “120” = 1 followed by 120 trailing ZEROS. However, 10 to the power “-120” = 1 followed by 119 leading ZEROS. Example: 103 = 1000 (with 3 trailing zeroes) but 10-3 = 0.001 (with 2 leading zeroes).
Way you wrote this seems wrong
Excellent. And for that beautiful conclusion, Andrei; thankyou!
What is maddening for me is the distance between all these parallel worlds so that although we are there somewhere else and ultimately infinitely, and conclusionarily immortally.... We die and never live again... If even to meet just another one of us for the briefest of plank super fluidity.... ....time.
The great minds of our species and our achievements as humans are really remarkable ... Just think about it. We haven't even gotten one human to our nearest planetary neighbour in our tiny solar system and yet, we can propose such ideas like an infinite amount of universes.
overTIMe not that i disagree but in the same referance frame Billions of human beings are borne, live and die in filth and excrements, unable to touch the potential of their nature, not knowing poetry, love, comfort, the thrill of scientific knowledge, etc etc, ever... human nature is truly encompassing a large gamut of mental attitudes ranging from the most beautiful spiritual minds to downright mass murderers, which sadly are the ones who our culture deems successful or representing authority. needless to say the large majority of the middle class (the one who theoretically has education and power) are narrow minded ignorants which is the main reason this stale situation is here to stay
overTIMe because the universe is like hologram. If you know one part you know it all. Ancient philosophers knew it and for this reason they argued that only understanding of own mind can lead to understanding of everything
***** humans are the only self domesticated species, and, providing the vast time scales of social evolution it was only normal that a certain category of us would get at the helm of that process. i was fascinated by reading about a natural process encountered in various niches, that takes the form of a paradox: in some rich environments the biodiversity among tree species, for example, is poorer than in zones with scarcity. the explanation is that in the areas with plenty of sunny days per year, with rich soils and abundant water, some species that got the slightest head start, eventually began to leave their rivals far behind in their battle for the light of the sun. thus the gap can only grow in an accelerated fashion, eventually a few species having grown spectacularly and leaving the others in the dark (besides the sunlight there were other factors including subterranean root wars). the very same kind of process created a huge discrepancy in human society, hence some individuals have almost god like powers (god equating an entity who can predict the future, has the means to change it and has powers over human life). for the last century, enormous financial entities had besides virtually unlimited amounts of money, the power to access the new realms of science. today almost all research is privately funded meaning the results of research into: behaviour of the masses, individual psychology, cybernetics, economics, genetic research, disease research, human life expectancy, meteorology, geology, information theory, signal theory, etc etc are all under private rights and ownership. if you ad to this the power of todays super computing machines you get the real possibility that the elite few have the capacity of seeing into the future (like some banks provide their top customers access to research into how global warming will affect markets and especially agriculture related business) and the means to change the future, or at least adapt to it beforehand. the same means gave them power to engineer society, to program those semi domesticated primates you talk about, the manufacturing of consent as adam curtis puts it in his series. i recommend "the century of the self - happiness machines" to see a history of this process. one can only dream at what kind of insights into the human mind and means of controlling it can some muster with the aid of 2015 science.
+anywherein12seconds - Yet their hubris will catch up to them. These you mention are among those who are behind the destruction of their own life-support system in their rush to poison the rest of us for profit (babies (the young of humans) born pre-polluted with +/- 200 synthetic chemicals detectable in their cord blood). These are those who have always lived uphill, upstream, upwind of the fallout of their actions; yet now their toxic waste is detectable in the most remote places on Earth. They can run, but they can no longer hide. Though they obviously have more resources and can make sure to have less exposure to the toxins, radiation, etc they cannot escape the fact that they, too, are biological entities. Or that all life on this planet co-evolved and is therefore really part of one system. The privitization of scientific research, or knowledge itself, is an important issue, as you point out. So it the privitization of life itself - as in 'patents' on life forms. Which, though explicity forbidden in the US constitution, have been granted - not just on mangled life forms from corporate labs - but also on life forms those corporations had nothing to do with 'creating'. The legal (sort of) fiction of the ownership of life should have everyone on the planet in protest. Especially as these corporations are successfully claiming the 'rights' of People. 'Slavery is the (psuedo) legal fiction that People are property. Corporate persons are the (psuedo) legal fiction that property is a person.' Best regards-
you have to learn the differences between scientitst's opinion and science..there are not evidence to support the idea that there are other universes out of there....
superb content
1:42:28 That story and joke were so good that, alone at home, I started applauding along with the audience XD
I checked it 100 times, these are my heroes, the moderator I think is not a bad, humorous style
I always enjoy listening to Alan and Brian, they do a wonderful job of explaining things.
BRIAN'S THE BEST ONE THERE... ALAN SEEMS A BIT COOL
How I love these great great conversations. God bless the KZhead!
Why do we exist? Because we can. Simple and beautiful.Can you imagine knowing the answer to every question? It would be dark and deppressing.
Ty S people mostly speak as though they know. I love the wondering, pondering, discussing possibilities but it’s ridiculous to pretend any person knows truth about the multiverse idea.
Oh my, I love hearing him speak. He is so handsome.....I'm in awe of the speaker.
good job..
I often wonder if time actually exists or if it is just an illusion that it moves along. Maybe everything always exists all the time but we can only see where we are at the moment, like looking at the Grand Canyon at night with a pen light. The whole Grand Canyon is there, but my tiny light can only reveal a little spot of it.
I know exactly what you mean and I also think that may be true. Like all events that ever happened are happening now, except we only see our "timeline"
Most NDE'S describe a place where there is no time. There is only the present. That seems to be where God lives. Where He was, is and is to come, the only way we can understand the mystery.
All things that ever was/is/ever will be exist now. Just my thoughts.
@@deborahthalman6680 No that is not the only way that WE can understand it. You then have a lot of explaining to do, you can't just leave it at 'Thats where God lives' for fuck sake man.
Wow. Makes me feel smaller and less substantial than before. Good thing we're all everlasting energy.
Most excellent presentation, mind expanding and exciting to reflect upon!
Great talk, and I love how the moderator kept it light mooded and funny, while staying on topic and keeping it interesting.
I understand the concept and need for and "layman" mediator but is it really necessary to find the absolute lowest common denominator...
'lowest common denominator' PMSL
Lol damn bruh
I agree. Just compare the expert humbleness of Brian and the rest to the sarcastic, proud ignorance of the "host". Curiously, the ignorant and unintelligent just dismiss your fair criticism in their comments...
Awesome Meeting of the Minds...Speaking of which ..They Just Melted My Mind... However my Theory is...There is No Beginning and There is No End...it just IS.
Amazing 👏. I'm forever finding validation in these gentlemens work.. I wasn't able to conceptualize this ..until now
Does the expansion of space/time slow time down? I would think so because constantly moving faster
