  • Multiverse: One Universe or Many?

    1:22:35

    The inflationary theory of cosmology, an enduring theory about our universe and how it was formed, explains that just after the Big Bang, the universe went through a period of rapid expansion. This theory has been critical to understanding what’s going on in the cosmos today. But now, this long-held notion—which seems to suggest as-yet-unproven and perhaps unprovable features such as the multiverse—is under increasing attack. Through informed debate among architects of the inflationary theory and its prime competitors, this program explored our best attempts to understand where we came from.

    This program is part of the Big Ideas Series

  • The Multiverse Hypothesis Explained by Neil deGrasse Tyson

    10:03

    The multiverse hypothesis or theory holds that a group of multiple universes (possibly infinite universes) comprise everything that exists: The entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. The renowned astrophysicist Neil deGrasse Tyson explains in detail the multiverse hypothesis.

    However, prominent physicists are divided about whether any other universes exist outside of our own. Some even go as far as to say that the multiverse is not a legitimate topic of scientific inquiry. Because it can not be empirically falsified. But Neil deGrasse Tyson among other prominent cosmologists, thinks that given our understanding of quantum mechanics and the thoery of General relativity, the possibility of the existence of the multiverse is a legitimate scientific hypothesis.

    Steven Weinberg said that if the multiverse existed, the hope of finding a rational explanation for the precise values of quark masses and other constants of the standard model that we observe in our Big Bang is doomed, for their values would be an accident of the particular part of the multiverse in which we live.

    Some scientists analyzed the data from the Wilkinson Microwave Anisotropy Probe, an uncrewed spacecraft operating from 2001 to 2010 that measured temperature differences across the sky in the cosmic microwave background, the radiant heat remaining from the Big Bang, and claimed they found evidence suggesting that our universe collided with other parallel universes in the distant past.

    However, a more thorough data analysis from the Wilkinson Microwave Anisotropy Probe and from the Planck Satellite, a space observatory operated by the European Space Agency from 2009 to 2013, which mapped the anisotropies of the cosmic microwave background, did not find any statistically significant evidence of universe collisions. there was no evidence of any gravitational pull of other universes on ours either. And to add insult to injury to the proponents that the multiverse hypothesis has been backed up by statistical evidence, the Planck satellite, has a resolution three times higher than the WMA Probe.


    Our brains are not evolutionarily equipped to intuitively understand quantum mechanics and large scale cosmic phenomena. But Neil deGrasse Tyson with his usual wits explains the multiverse hypothesis in layman's terms.

    Code for solving the Schrödinger equation by Jonny Hyman available here:

    I learned quantum mechanics the traditional 'Copenhagen Interpretation' way. We can use the Schrödinger equation to solve for and evolve wave functions. Then we invoke wave-particle duality, in essence things we detect as particles can behave as waves when they aren't interacting with anything. But when there is a measurement, the wave function collapses leaving us with a definite particle detection. If we repeat the experiment many times, we find the statistics of these results mirror the amplitude of the wave function squared. Hence the Born rule came into being, saying the wave function should be interpreted statistically, that our universe at the most fundamental scale is probabilistic rather than deterministic. This did not sit well with scientists like Einstein and Schrödinger who believed there must be more going on, perhaps 'hidden variables'.

    In the 1950's Hugh Everett proposed the Many Worlds interpretation of quantum mechanics. It is so logical in hindsight but with a bias towards the classical world, experiments and measurements to guide their thinking, it's understandable why the founders of quantum theory didn't come up with it. Rather than proposing different dynamics for measurement, Everett suggests that measurement is something that happens naturally in the course of quantum particles interacting with each other. The conclusion is inescapable. There is nothing special about measurement, it is just the observer becoming entangled with a wave function in a superposition. Since one observer can experience only their own branch, it appears as if the other possibilities have disappeared but in reality there is no reason why they could not still exist and just fail to interact with the other branches. This is caused by environmental decoherence.

    The Copenhagen interpretation of quantum mechanics tells us that observation collapses a probability wave into a single definitive outcome, but this isn’t the only interpretation of quantum mechanics. The many worlds theory proposes that the wavefunction never actually collapses. The observer simply follows one of those many possible paths into their present reality while all the other paths continue on independent of the observer. Each of these paths branches off into an entirely different reality. In this episode Matt discusses the details of the many worlds theory and why it’s not so far-fetched to think that our reality is simply one of an infinite number of realities existing within space time.

    SCIENTIFIC NOTES

    Many physicists believe there is a strong connection between the inflationary multiverse and an important feature of string theory; for more see

    Although there is not yet evidence favoring the quantum multiverse over several other interpretations of quantum mechanics, it is still consistent with the results of every quantum experiment ever conducted.

    Blog post with audio player, show notes, and transcript:

    Patreon:

    String theory was originally proposed as a relatively modest attempt to explain some features of strongly-interacting particles, but before too long developed into an ambitious attempt to unite all the forces of nature into a single theory. The great thing about physics is that your theories don’t always go where you want them to, and string theory has had some twists and turns along the way. One major challenge facing the theory is the fact that there are many different ways to connect the deep principles of the theory to the specifics of a four-dimensional world; all of these may actually exist out there in the world, in the form of a cosmological multiverse. Brian Greene is an accomplished string theorist as well as one of the world’s most successful popularizers and advocates for science. We talk about string theory, its cosmological puzzles and promises, and what the future might hold. (For more general string theory background, check out Episode 18 with Clifford Johnson.)

    Brian Greene received his doctorate from Oxford University, and is currently a professor of Physics and Mathematics at Columbia University. His research includes foundational work on topology change, mirror symmetry, and the compactification of extra dimensions. He is the author of several best-selling books, including The Elegant Universe and The Fabric of the Cosmos, both of which were made into TV specials for NOVA. He and Tracy Day are co-founders of the World Science Festival.

  • Do we live in a multiverse? | The Economist

    8:58

    It has long been thought that our universe is all there is, but it is possible we may live in just one of many. This is the second in our six-part series on unsolved mysteries in science. Read the accompanying article:

    Subscribe NOW to The Economist:

    When the ancients looked into the night sky they thought the heavens revolved around the earth and mankind. over the centuries this view has changed radically.

    We discovered we lived on a planet orbiting a star within the solar system and the solar system was found to be part of the Milky Way galaxy. Later we learned that our universe was filled with billions of other such galaxies - but could it be that we're committing the same error as our ancestors by thinking the universe contains everything there is? Could it be that we live in a multiverse?

    There are a number of different theories about what the multiverse could be. One proponent of the idea of the multiverse is Dr Tegmark of MIT. Dr Tegmark suggests a four fold classification of possible types of multiverse. The first type of multiverse is just an extension of what we already know our universe expanding into infinity rather than ending at the limits of our vision.

    We can look back almost to the beginning of time to the edge of the observable universe, but we can see no further. So the space beyond that distance known as the Hubble radius is literally out of sight. But that doesn't mean there isn't anything there.

    Because the expansion of the universe has stretched space, astronomers are able to see out to a distance of about 42 billion light years. How far things extend beyond this is unknown. If they stretch to infinity there could be numerous isolated universes cut off from one another by their own Hubble radius - depending on the observers vantage point.

    To understand the second type of multiverse in Dr Tegmark system it is first necessary to understand how the universe was formed and the theory of inflation. It was first conceived of by Alan Guth in 1979 and then later refined and expanded upon by Andrei Linde who had some key insights.

    This is one of the ideas of string theory which attempts to unify general relativity with quantum mechanics. The thinking is that all of the solutions produced by string theory that don't match up with what we can see in our own universe, may actually represent reality in other universes.

    The anthropic principle is the idea that our universe is fine-tuned to allow humans to live. A small fiddle with the strength of gravity for example and life as we know it would not exist - a coincidence that does not sit easily with scientists. The concept of a multiverse neatly addresses this problem within the infinite number of universes that could exist we are simply living in the one we are able to.

    In the third type Dr Tegmark multiverse in the first the laws of physics are the same from one to another. In this type though the component universes are separated not by distance but by time. At every moment within such a multiverse all of the possible futures allowed by the uncertainties of quantum mechanics actually happen.

    In the many worlds theory of the multiverse the entirety of the universe acts like the quantum photon, but instead of having two potential future states, every possible outcome would be manifested so our entire universe and everything within it, including you, would be constantly undergoing multiple visions into daughter universes - each with its own reality and future. Any given observer though would only see one outcome.

    In the final classification, the level 4 multiverse, Dr Tegmark proposes that all coherent mathematical systems describe a physical reality of some sort. Those different systems are of necessity different universes. What this last idea translates to in practice is hard to conceive of - it is more the province of metaphysics than physics, but the other three types of multiverse though they push the bounds of physical theory do not overstep them. Observational data supporting the theory of inflation have convinced some scientists that a multiverse is possible - but the idea is still controversial.

    It may be impossible to ever directly observe the multiverse but some scientists hope to eventually gather enough data supporting the theories that predict it to one day confirm its existence. If that were to happen, like the ancients before us, we would be given a whole new perspective on how the cosmos works and on our place in it.

  • Multiverse: One Universe or Many?

    1:10

    Could we be living in one of an infinite number of universes? The inflationary theory of cosmology seems to add weight to this as-yet-unproven (and perhaps unprovable) idea called the multiverse. But the notion of multiple universes is not without its opponents.

    Inflation, an enduring theory about our universe and how it was formed, proposes that just after the Big Bang, the universe underwent a period of rapid expansion. The theory has historically done a good job explaining a wide range of phenomena we see in the cosmos today. But to the extent this long-held notion also suggest we live in a multiverse, the theory is coming under attack. Through informed debate among architects of the inflationary theory and its prime competitors, Multiverse: One Universe or Many? explores our best attempts to understand whether our universe is unique—or one in a million million million.

  • Does the Multiverse Really Exist? |Space Science Documentary

    48:59

    The word “multiverse” has different meanings. Astronomers are able to see out to a distance of about 42 billion light-years, our cosmic visual horizon. We have no reason to suspect the universe stops there. Beyond it could be many—even infinitely many—domains much like the one we see. Each has a different initial distribution of matter, but the same laws of physics operate in all. Nearly all cosmologists today (including me) accept this type of multiverse, which Max Tegmark calls “level 1.” Yet some go further. They suggest completely different kinds of universes, with different physics, different histories, maybe different numbers of spatial dimensions. Most will be sterile, although some will be teeming with life. A chief proponent of this “level 2” multiverse is Alexander Vilenkin, who paints a dramatic picture of an infinite set of universes with an infinite number of galaxies, an infinite number of planets and an infinite number of people with your name who are reading this article.

  • Multiverse Theory, Explained

    Business Insider UK spoke with astronomer Stuart Clark, author of Unknown Universe, about multiverse theory.

    He explained how a number of problems in physics and astronomy could be solved if there were an infinite number of other universes.

    He says: I think for me I would prefer it if there wasn’t a multiverse. If the universe that we see around us today is all that there actually is and that that spurs us on to find the meaning if you like in the laws of physics, the reason the universe is just this way and no different.

    But of course, the universe doesn’t have to care what I think or want. It will just do what it does.

  • The Multiverse Hypothesis Explained by Max Tegmark

    10:02

    The multiverse hypothesis has attracted attention over the last few years but in actuality it's a very old idea going back to the ancient Greeks where they imagined the concept of infinite worlds. However the multiverse hypothesis has been under scrutiny only in the time of modern physics.

    Dr. Max Tegmark is a Swedish-American Physicist, Cosmologist, & Professor at MIT. He explains in detail the multiverse hypothesis. According to Max Tegmark, the multiverse is not just a staple of science fiction. He argues that there are at least 4 different kinds of parallel universes lurking out there. Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. They are arranged such that subsequent levels can be understood to encompass and expand upon previous levels.

    A common feature of all four multiverse levels is that the simplest and arguably most elegant theory involves parallel universes by default.

    Prominent physicists are divided about whether any other universes exist outside of our own.

    Some of them think that the multiverse theory could at least be rendered more plausible, by the existence of dark energy in our universe.

    However, others argue that the multiverse is a philosophical notion rather than a scientific hypothesis because it cannot be empirically falsified.

    If our universe were merely one of infinitely many, there would be no way to confirm that any of the others are distinct rather than part of an infinite multiverse. In other words, no external observer could ever determine whether his universe was special in the sense that it is exempted from sharing its characteristics with other universes.

  • The Multiverse Hypothesis Explained by Brian Greene

    11:04

    The multiverse hypothesis and the concept of multiple universes depends on the conception of reality as a four-dimensional space-time continuum in which everything that could possibly happen does happen in some universe. The prominent theoretical physicist, mathematician, and string theorist Brian Greene explains the multiverse hypothesis in detail.

    The multiverse hypothesis has been criticized for a number of reasons:

    Some physicists claim that the multiverse hypothesis is not falsifiable, and therefore not scientific. In response, defenders claim that the multiverse is testable and some suggest it may be more scientific than certain other untestable theories.

    Some proponents of the theory say there are an infinite number of conceivable universes. According to quantum mechanics, universes without any classical space and time—idealised as sets of quantum wavefunctions—cannot be directly observed because they do not interact with anything in our universe and would have no effect on future events in our universe.

    Brian Greene explains our universe would be affected by the ripples from bubbles of another universe that it bumps into as it passes by. However multiverse models are problematic because they can not explain why the Big Bang happened at all or why the laws of physics are as they are today, which seem to follow from mathematical constants.

    The American theoretical physicist and string theorist Brian Greene discussed nine types of multiverses.

    A multiverse of a somewhat different kind has been envisaged within string theory and its higher-dimensional extension, M-theory. But we will discuss these theories extensively in another video.

  • Universe Or Multiverse?

    55:47

    Recent developments in cosmology and particle physics, such as the string landscape picture, have led to the remarkable realization that our universe - rather than being unique - could be just one of many universes. The multiverse proposal helps to explain the origin of the universe and some of its observational features.

    Since the physical constants can be different in other universes, the fine-tunings which appear necessary for the emergence of life may also be explained. Nevertheless, many physicists remain uncomfortable with the multiverse proposal, since it is highly speculative and perhaps untestable. .

    The fact that no one knows the answer to this question is what makes it exciting. The story of physics has been one of an ever-expanding understanding of the sheer scale of reality, to the point where physicists are now postulating that there may be far more universes than just our own. Chris Anderson explores the thrilling implications of this idea.

  • One Universe Theory

    8:46

    This videos explains a three dimensional process of continuous energy exchange that forms the ever changing world of our everyday life. The reason why this process can be explained in just three dimensions is because in uses the holographic principle in the form of positive and negative charge forming a dynamic two dimensional boundary condition. In such a theory the extra dimensions of String Theory and parallel universes of the Many Worlds Interpretation are just future possibilities and opportunities in our one 3D Universe. We have an emergent future continuously unfolding with the spontaneous absorption and emission of light forming a process of continuous energy exchange that we see and feel as the flow of 'time' itself with the future coming into existence photon by photon. The wave particle duality of light is continuously forming a blank canvas that we can interact with forming the possible into the actual! This universal process is unfolding within an infinite number of dynamic interactive reference frames that are continuously coming in and out of existence. Some people find it hard to believe that everything could be based on one universal process that can be explained by physics. I think this is because of the great diversity of the atoms of the periodic table and because we have phase changes in matter at different temperatures. Also we have the four fundamental forces that have to be explained within a universal process for this to be possible. Add to this at high temperature we have matter changing into plasma, so it is not surprising people find it difficult to comprehend. This video explains a simple process that is relative to the atoms and the four fundamental forces. It is also relative to temperature with the phase changes of matter solid, liquid, gas and plasma.

  • Multiverse: In the Beginning

    4:43

    What if the big bang that produced our universe wasn't the only one? Is it possible that universes are being created all the time? Some scientists suspect a theory supposing a collection of universes—dubbed the multiverse—could answer many of the questions surrounding our origins and the nature of space-time. But the notion of multiple universes is not without its opponents. Take a visual tour from the beginning of time all the way to the roiling debate amongst physicists today.

  • Universe or Multiverse?

    1:10:39

    Cosmological observations show that on the largest scales accessible to our telescopes, the universe is very uniform, and the same laws of physics operate in all the parts of it that we can see. Rather paradoxically, the theory that explains this uniformity also predicts that on extremely large scales, the situation may look totally different. Instead of being a single spherically symmetric balloon, our universe may look like a multiverse—a collection of many different exponentially large balloons with different laws of physics operating in each. In the beginning, this picture looked more like a piece of science fiction than a scientific theory. However, recent developments in inflationary cosmology, particle physics, and string theory provide strong evidence supporting this new cosmological paradigm.

    The conversation will be moderated by George Washington University School of Media and Public Affairs Director and Emmy winning journalist Frank Sesno.

    51:35

    Multiverse Documentary - Beyond Dimensions and forces.
    This concept haunts scientists ,How is it possible that a single universe has everything so perfect? Its a wonderful concept.New discoveries are being made about this , but there is no absolute evidence that multiverses exist.At the same time there is absolutely no chance that a universe in which we live in can be so perfect without a creator.
    Multiple universes have been hypothesized in astronomy, physics, religion, philosophy, psychology. Concept of parallel universe is not new .It is only now that physicists are realizing that a single universe with all the forces of nature absolutely perfect is not a chance unless there is a creator,or there have to be many many universes just like ours with different types of forces .

    In the past decades, the idea that our universe is only one of many, has become popular among physicists. If there are several universes, their collection is called the “multiverse”, and physicists have a few theories for this that I explain in this video.

    First, there is Eternal inflation
    Second, the String Theory Landscape
    Third, Many Worlds

  • Universe or Multiverse? With Thomas Hertog

    43:49

    For more cool science visit
    To the Edge of Time with Stephen Hawking.
    Yes, ladies and gentlemen! Another round of Science & Cocktails begins with rising star cosmologist and string theorist, the man who published with Stephen Hawking countless times, Thomas Hertog. Does time come to an end inside black holes? Do black holes exist forever? Did the universe have a beginning? Or was there something before the big bang? Is there only one universe or are there many? Can we hop from one universe to another? Why does the universe bother to exist at all? ? What was Stephen Hawking’s quantum theory of the origin of the universe? This is Thomas Hertog's description of this evening that will blow your mind: Stephen Hawking once said “My goal is simple: It is a complete understanding of the universe.” I have been fortunate to collaborate with Hawking to work towards this goal. Our search for a deeper understanding led us to realms of our universe at the edges of time. The end of time deep inside black holes, and the beginning of time at the big bang. Quantum theory rules the world at those edges. Its fuzziness and uncertainty means out of the big bang does not emerge a single universe but many universes - a multiverse. The multiverse challenges science as we know it, and Hawking wasn’t pleased. Thus we set out to weave the multiverse into a proper scientific model that is testable within our own universe. Universe or Multiverse? An inside story of how Hawking’s journey to the edges of time has reshaped our vision of the cosmos, and of ourselves.
