Our books, our movies-our imaginations-are obsessed with extra dimensions, alternate timelines, and the sense that all we see might not be all there is. In short, we can’t stop thinking about the multiverse. As it turns out, physicists are similarly captivated.
In The Allure of the Multiverse, physicist Paul Halpern tells the epic story of how science became besotted with the multiverse, and the controversies that ensued. The questions that brought scientists to this point are big and deep: Is reality such that anything can happen, must happen? How does quantum mechanics “choose” the outcomes of its apparently random processes? And why is the universe habitable? Each question quickly leads to the multiverse. Drawing on centuries of disputation and deep vision, from luminaries like Nietzsche, Einstein, and the creators of the Marvel Cinematic Universe, Halpern reveals the multiplicity of multiverses that scientists have imagined to make sense of our reality. Whether we live in one of many different possible universes, or simply the only one there is, might never be certain. But Halpern shows one thing for sure: how stimulating it can be to try to find out.
Shermer and Halpern discuss: definitions of universe and types of multiverses • Is the multiverse science, metaphysics, or faith? • theists claim the “multiverse” is just handwaving around the God answer • many worlds interpretation of quantum mechanics? • inflationary and Darwinian cosmology • infinity and eternity • multiple dimensions • string theory • cyclical universes • Big Bounce • Anthropic Principle (weak, strong, participatory) • time travel • sliding doors, contingency, and the multiverse.
Dr. Paul Halpern is the author of 18 popular science books, exploring the subjects of space, time, higher dimensions, dark energy, dark matter, exoplanets, particle physics, and cosmology. The recipient of a Guggenheim Fellowship, a Fulbright Scholarship, and an Athenaeum Literary Award, he has contributed to Nature, Physics Today, Aeon, NOVA’s “The Nature of Reality” physics blog, and Forbes “Starts with a Bang!” He has appeared on numerous radio and television shows including “Future Quest,” “Science Friday,” “Radio Times,” “Coast to Coast AM,” “The Simpsons 20th Anniversary Special,” and C-SPAN’s “BookTV.” He appeared previously on the show for his book Synchronicity: The Epic Quest to Understand the Quantum Nature of Cause and Effect. His new book, The Allure of the Multiverse, describes the controversial history of higher dimensional and parallel universe schemes in science and culture.

Ok. People repeat the multiuniverse claim not knowing what it realy means. Multiverse evolves from understanding Nature at a fundamental level. I will not explain the Nature fundamentally, but I will tell you about multiverse.
Firstly, multiverse is an infinite speck of TheAll. TheAll contains realities like ours (ie other multiverses) but also realities that are different to ours in a way that cannot be understood by us where physical laws are totally different.
Our reality is created by a black hole, ie we live in a black hole which resides in another universe, and that universe in turn resides in another black hole, etc.
But, it is not anothet space or room that we live in inside a black hole. The blck hole creates fractal patters which sometimes produce intelligent beings who mentally create their reality based on these patters.
So what is a black hole and how does this creation work?
Black holes are similar to magnets with north and south poles. Magnetic particles swirl out of these poles in all helical directions. Some will follow a path that takes them through the polar path (bloch wall) where they asimptotically approach this region. The same path is taken by particles from the opposite pole and heading head to the other particles. Black holes obsorbe gravitons through this polar path (bloch wall) creating a circumferential disk of graviton particles. The magnetic particles enter this disk and grind through it and in the process creating monopoles. It is from the monopoles that everything in our universe is created. One must remember that these proceses are exponentially small and they create other exponentially small things all the way to quarks in one plane. This represents a slice of time and space, by repetition (relentless magnetic particle streaming) and fractal depth of field patters are creared in slices which are us. Herein, minds create their own interpertation of reality patters which is consciousness.
The moments in time are effected by opposing magnetic field particles comming together head on and ineffect causing destruction of both universe and antiuniverse moment in time. The repetition is the creation and destruction process.
I have left many datails out but, the reader shuld get some real idea where these ideas come from.
Thank you for creating amazing content in the last few decades.
Dear Michael, the title of Gregory Benford's wonderful 1980 novel is Timescape. I recommend reading it too -- It is no less relevant today than at the time of its publication.
Btw. Paul might be interested in getting his hands on a list that a friend of mine made of approx. 1,500 multiverse and time travel movies (their directors, titles, year of production, country of origin, iinks to those available on TH-cam and so forth).
The apparent acceleration of the universe is also a 13.8 billion year old acceleration signature. Shouldn't we have to wait 13.8 billion years to know the currant acceleration of the universe as it's currently expanded? If the photons are 13+ billion years old, so it should follow that the apparent acceleration rate is also a remnant.
Love Paul!
Interesting , i liked his intelligent views on AI ...
I feel like I need to do mushrooms to just begin to understand what top level physicists are saying about the universe, how it was created, and how many (infinite?) universes there are! Pass the doobie prof!
Yup, scientists have drug powered delusions too
I didn't know the food stands in football stadiums served word salad.
I remember reading books about alternate universes and dimensions back int he 50's. A collection of stories by leading authors from the 1930's to early 1950's edited by Groff Conklin comes to mind.
Whatever happened to Occams Razor? You know scientists have lost their way when, lacking an explanation for certain phenomenon, they explain away their failure by saying ... well, everything is not only possible, it actually exists in some other forever unobservable universe. Great. Thanks.
Exactly!
Vacuum energy, field forces--these are not nothing in the robust sense that philosophers mean when we say "ex nihilo nihil fit"
'Vacuum' in the traditional philosophical usage is simply unphysical. There is, and can be, no such thing. I have a fit whenever I see that tired old philosophical chestnut. Philosophers should simply learn some physics more recent than the middle ages.
Versions of time?
Time is a measurement.
It's all it is.
The "Will" is not a topic of physics.
We have free will, we have choices, it's nothing to do with physics.
Is it just me or was that the most awkward (possibly wrong) answer to Michael's question at 14:00 ? I thought Michael was asking that if the big bang was 13 billion years ago, and nothing can travel faster than light, then isn't the diameter of the universe 26 billion light years? The answer to which I thought was cosmic inflation is the actual inflation of space and can be greater than the speed of light. Halpern gets into some weird football analogy which made absolutely no sense to me. Maybe he didn't understand Michael's question?
I know right!
"Some of God's greatest gifts are Unanswered Prayers" - Garth Brooks
...Not that I'm a particular fan of country or gods.
Be fair. Also some of its greatest curses.
Michael has an open mind and asks good questions. Physicists ask us to grant them one miracle as the source of creation. The only thing we know is we don’t know what’s going on. Each time we claim to know we find the story is much deeper than we thought.
It's a materialist/atheist coping mechanism. They would rather believe this fairy tale marvel nonsense that admit there's an infinite God.
@@JulianH-co7qg The fairy tale is god. It's a man made creation. It's your coping mechanism which is fine .....but do you ever think you might be wrong.? Ever? Or do you just live your life as this unquestioning sheep. Do this, believe that. Based on an old ,old book written when people believed that stars were celestial beings. I understand absolutely how they concluded this then.But you have no excuse at all.
@simonrae3048
I think you're mistaking me for some Christian fundamentalist. God is real, and you know it. It's not the god of the biblical scriptures if that's what you're thinking.
@@JulianH-co7qgif we define god as the one that created the universe in 6 days and made Adam from dirt and Eve from his rib then that god does not exist since we know the universe took at least 13.8 billion years and we evolved from other mammals which came from reptiles which came from fish.
If you define god as some energy that started the Big Bang then yeah, god exists but that’s NOT what people consider to be god. A god is all powerful and is worshiped and is conscious. We don’t worship that energy and it’s not conscious or desire worshiping.
So you sound like Jordan Peterson redefining god so atheists can’t say they don’t believe in god. You can’t redefine terms and have a proper conversation.

Hey buddy, I'm not here to have a convention with you.
Like you can answer this question, as a human, if you have enough education. This guy knows. Okay. I'm off to watch bears frolicking in suburban swimming pools and cat videos.
Cool. Maybe parallel universes might exit. We only know less than ~.0000000000000000001% of the Universe... so why not since we don't know anything... not even the life under Jupiter's moon Europa
How is the belief in a multiverse not just another form of faith that deserves the same amount of skepticism as any religion? We all scoff at a man walking on water, deities, resurrection, etc, but willing to entertain the possibility of a multiverse? Seems silly without a lot of evidence.
For one simple reason - nothing else in nature has happened only one time. There is more than one galaxy in the universe, more than one star in our galaxy, more than one planet around our star, more than one forest on earth, more than one tree in a forest, more than one branch on a tree and more than one leaf on a branch. So I think it would be silly to assume only one universe, and THAT would require a lot of evidence!
Depends on what one means by the word universe. It sounds like your just talking about another place in space. Not a whole other plane of existence
There is no such thing as "parallel universes." This is just a coping mechanism by materialists to explain reality. There are other planets out there from many star clusters within constellations that have life that we've been in contact with.
UFOs are known unknowns.
This is hardly controversial. We know that we don't know some important things (Grand Unified Theory). We can explain about four percent of the observable universe, the rest being dark matter/energy. We know people are experiencing, but those things are not reproducible, which is essential to the scientific method.
Not one true earther believes that the earth is a pizza disc flying around the sun the way you described it. Why misrepresent there model unless you are so small minded you can not look past what you believe?
The answer is NO! This notion was based on a misunderstood experiment.
the world of storytellers is real wonder!
This guy argues for the existence of other universes by pointing out that we infer the existence of other things in science from indirect observations, but fails to mention that we don't even have indirect observations of other universes, and the mathematics tells us that we never will. I thought that you were going to ask him about this when you brought up the point about things only being supported by the mathematics, but no. This guy gives me no reason to think he has anything insightful to say.
Math tells us we will never have indirect observations of other universes? I will have to listen again…reality is as we develop more powerful and sensitive equipment we could detect observations of other universes (math certainly does not tell us we will never develop such equipment so don’t understand your point) for that possibility. If universes have collided it could be detected in the cosmic background radiation…… in addition inflation leads to multiple bubble universes. Called indirect evidence….if inflation is correct then other bubble universes must certainly follow regardless if we could observe them.
This comment made turn this junk off right from the start 😂😅
Thats crazy
You’re not exactly correct. We know quantum fluctuations take place though we cannot directly observe the virtual particle themselves….but we do observe the gravitational effects that do take place from them. The expansion rate of the universe via measurements is expanding therefore we know something must be driving that expansion to overcome the known effects of gravity (something we call dark energy…we cannot directly observe but we indirectly observe its effects). Our universe on a geometrical scale is flat…..mathematically near impossible result from a Big Bang unless inflation took place….which guarantees a flat universe. We have direct evidence that inflation is a strong explanation for what took place at the initial expansion of our universe….and inflation leads to an uncomfortable conclusion for many….that once inflation begins it does not stop creating multiples of bubble universe each separate from each other (essentially a multi verse). Other mathematical theories are indicative of multiple universe like string theory….the math dictates if string theory is correct then a multi verse follows. Could we ever directly observe other universe? Probably not, could we develop more powerful and sensitive equipment that could indirectly give more credence to them (in addition to the math and other directly observed evidence that point to other universes)? Certainly so…one example would be a finer measurement of the cosmic background radiation and finding abnormalities which could be indicative of different universes colliding with each other. Bear in mind Einstein special theory of relativity predicted the universe has to be expanding (math clearly stated so) but he rejected his mathematical conclusion as astronomers at the time seem convinced the universe was static…so he added a fudge factor to stabilize the equation. Of course, Edwin Hubble came along and noticed the red shift of the light from other galaxies that clearly demonstrated yes the universe is expanding as the math clearly predicted. We should also note at that time it was believed only one galaxy existed the Milky Way….now we know hundreds of billions of galaxies actually exist….why would the existence of multiples of universes seem so unlikely?
BBT is irrational because it's an ontological impossibility. Nothing (0D) can't morph into something (3D) in zero time. If looking at a movie screen and the first screen is blank then whether it's the second slide or the 500th, how does an object appear. If the Universe (space + matter) is expanding then what is it expanding into? More space? What is that black stuff outside the Universe? I know all the experiments, like redshift but Andromeda is blue shifting, we have CMBR but that can be explained by the Sun's solar rays. The JWST is destroying the BBT as we speak. particle physics is destroying the theory of dark energy also. The most rational theory is that the Universe is eternal. Atoms assembling, disassembling and reassembling for eternity. Oh, also Infinite is an irrational concept. An intrinsic property of an object is shape. They are all finite. But infinite means unbounded or without shape. Infinity really means incessant counting. Science and physics in particular has nothing to do with Infinity.
How ridiculous does saving classical deterministic theories have to get before everyone accepts it for what it is? I do see more accepting newtons tools of approximation more now with the triality observers role in the paradoxical dualistic nature. But they're adopting crazy infinite many worlds , multi verses etc etc.
Fine tuning checklist is prescribed assumed higherachy values on objects with premium on carbon based life.
Personally this old Babylonian flood evolutionary soup mythology is failing . Already failed as far as I'm concerned.
It is funny how today's factions that argue against fundamental building block physics truly correlate to factions after working statistical anylitics argued for ending all great debate theory of everything there.
Atleast until we got answers then they become great allys of classical theories..
The suposition that there are extra dimensions is brought about by bored grad students looking for easy grant money, and low I.Q. government bureaucrats who are prone to falling for hyperbole about threats to the status quo.
Cool theories, but none of it can be proven now or likely ever. So its just philosophy that I call mental masturbation.
Ya got a problem with masturbation? Or just with pleasure? Calvinist, Catholic, or something?
@@davidwright8432 you seem triggered bro
It's fun to make fun of these people.
Sorry, but the multiverse is one of the most idiotic and worthless hypotheses ever. I guess some people have too much time on their hand. If you cannot find a better explanation for fine-tuning, just say so. It does not concede anything to the theists. But making up unfalsifiable nonsense is not the way to go. Man, why do I even have to say these things...
1:07:00 you and your multiverse are the illusion itself
