What is driving the mulitverse theory? Are the multiverse stories only a sticky-plaster solution to the Big Bang theory problem? Leading thinkers Sabine Hossenfelder, Roger Penrose and Michio Kaku debate.
00:00 Introduction
02:22 Michio Kaku | Multiverse theory has now dominating cosmology; it is unavoidable.
06:03 Sabine Hossenfelder | Believing in the multiverse is the logical equivalent to believing in God.
07:57 Roger Penrose | Universes are sequential and so are not independent worlds.
16:36 Theme 1 | Do scientifc theories need to be testable?
28:45 Theme 2 | Are tales of the multiverse solutions to the Big Bang theory in trouble?
42:49 Theme 3 | Will theories of the universe always be bound by untestable elements?
Multiverses are everywhere. Or at least the theory is. Everyone from physicists Stephen Hawking and Brian Greene to Marvel superheroes have shown their support for the idea. But critics argue that not only is the multiverse improbable, it is also fantasy and fundamentally unscientific as the theory can never be tested - a requirement that has defined science from its outset.
Should we reject the grand claims and leave multiverse theories to the pages of comic books? Are tales of the multiverse really sticking-plaster solutions for Big Bang theory in trouble? Or should we take multiverse theory as seriously as its proponents, and accept that modern science has moved beyond the bounds of experiment and into that of imagination?

Warum es kein weiteres Universum als ein Paralleluniversum geben kann? Die Hypothese über ein Paralleluniversum basiert auf der falschen Annahme, dass unser Gedanke, Geist, Seele oder Selbstbewusstsein eine Trennung vom Universum unterliegt. Daher können weder ein Paralleluniversum noch ein Jenseits existieren, da wir ohne eine Verbindung zwischen beiden niemals auf diese Idee kommen könnten. Deshalb führt die Kontinuität zwangsläufig zu einem Einheituniversum. Daraus folgt, dass eine Grenze nur dann als solche definierbar ist, wenn sie diffus und offen für eine Verbindung ist. Außerdem ist der Begriff Universum nicht mit Begriffen wie Erde, Stern, Galaxien vergleichbar, da Universum alles übertrifft, was wir uns vorstellen können, und auch unser Bewusstsein umfasst. Daran sollten wir immer denken! Ich zitiere an dieser Stelle von Emanuel Kant: "Zwei Dinge erfüllen das Gemüt mit immer neuer und zunehmender Bewunderung und Ehrfurcht, je öfter und anhaltender sich das Nachdenken damit beschäftigt; der bestirnte Himmel über mir und das moralische Gesetz in mir; beide darf ich nicht als in Dunkelheiten verhüllt oder in überschwänglich außer meinem Gesichtkreises suchen und bloß vermuten; ich sehe sie vor mir und verknüpfte sie unmittelbar mit dem Bewusstsein meiner Existenz!" Was heißt das eigentlich, wenn wir von einem Paralleluniversum sprechen? Um diese Frage zu beantworten, müssen wir einige Voraussetzungen festlegen: Parallel bedeutet, dass zwei Mengen keine Schnittstelle haben und keine Elemente voneinander besitzen. Oder anders ausgedrückt: Die Mengen A und B sind nicht parallel, wenn es mindestens ein Element gibt, das Teilmenge von A und B ist und somit eine Schnittmenge zwischen beiden Mengen gibt. Wenn wir jedes Universum als eine geschlossene Menge betrachten, dann sind zum Beispiel zwei Universen U und U' nur dann parallel, wenn kein Element von U oder U' existiert, das Teilmenge von beiden wäre. Es gilt: Wenn U:={ x |∀ x∈U ∧ x∉U' } ∧ U':={ x' |∀ x'∈U' ∧ x'∉U } ⇔ U ist echt parallel zu U'. Allein die Tatsache, dass wir uns vorstellen können, dass es ein Paralleluniversum gibt, ist ein Beweis dafür, dass es mindestens eine Schnittstelle zwischen unser Universum und dem gedachten Universum in unserem Bewusstsein gibt. Ansonsten hätten wir nie auf die Idee kommen können, dass es ein zweites Universum geben könnte. Die Idee eines Paralleluniversums ist zwar reizvoll, aber letztendlich nur eine Illusion. Dies würde nur dann der Fall sein, wenn man den kartesischen Dualismus annimmt, wonach Bewusstsein und Welt/Materie getrennt sind. Doch bevor man dies annehmen kann, müsste man erst beweisen, dass diese Annahme richtig ist, doch stattdessen führt es in jedem Fall zum Absurdum. Es ist eine unumstößliche Tatsache, dass wir in dieser Welt leben und unser Bewusstsein nicht ohne unseren Körper existieren kann. Es ist also unmöglich, einen Beweis für die Existenz eines vom Körper getrennten Geistes zu liefern! Es bleibt wie J.W. Von Goethe sagte: "Was wär ein Gott, der nur von außen stieße, Im Kreis das All am Finger laufen ließe. Ihm ziemt's die Welt im Innern zu bewegen. Natur in sich, sich in Natur zu hegen. So dass was in Ihm lebt und webt und ist, Nie seine Kraft, nie seinen Geist vermisst."

Yep, agreed....the problem with modern science is that there is a tendency to compartmentalize, to break apart into divisions when Newton himself said we are only beginning to realize that how small we are "now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me". The problem is these scientists distance themselves from integrating spirituality and the so-called "supernatural" when far advanced civilisations of our past integrate metaphysics, spirituality and so on...I remember my grandpa told me what was taught to Adam was alchemy (the pure sciences at microlevel-lower) and astrology (incldg astronomy- the sciences of the higher levels and of higher dimensions, not withstanding the conflict modern science has about multiverses...disregarding the souls, God, consciousness etc...)

I don't see this. First of all, string theory and quantum mechanics are related. And Penrose was not talking about cosmology. The background knowledge for this is that Newtonian physics works and makes accurate predictions, and quantum physics works and makes accurate predictions, but they describe the universe very differently to the point that you'd think they're describing different universes. Some scientists have come up with a mathematical untestable theory called string theory which theoretically unites both spheres of physics, and in the process predicts the existence of multiverses. Where they mainly differ is in substance and presentation. Someone like Michio Kaku is a very enthusiastic popularizer of science, and tends to gloss over a lot of details to make the science accessible, where Sabine Hossenfelder is a critic of the muddled views that emerge from such enthusiastic simplification. Roger Penrose is talking about the multiverse in general, and is wondering why they are talking about string theory as if it's the only theory that predicts multiverses - since he doesn't think string theory is very coherent at all. They're not talking at cross purposes.

The thing is that all these scientists should not latch onto a favorite theory but keep everything, all options wide open. Pure math has made real predictions , as in the positron. Also not using math and only experiments have discovered most things. So all lines of pursuit should be followed up on. Scientists in all areas do this and latch onto their favorite. I don't like it.

@alecepting1371
@alecepting1371 Місяць тому
I think the point that was made that the math doesn't always correspond to reality ontologically, and even if it does correspond to experimental results on many fronts, like quantum theory, then the inherent contradictions such a theory presents as Penrose pointed out, is contrary to the law of noncontradiction in logic which is the basis for the mathematical rigor that the epistemology of philosophy demands and that science has adopted. How can science which is based on inductive reasoning ever prove the theory of everything for every possible claim of the theory if not every claim is testable? That seems to me to be one of the great shortcomings of the scientific method. And even if the mathematics of a theory claims much more than can actually be proven experimentally, you have Goedel's Incompleteness proof to contend with. So we all have to admit at some point, that we cannot know everything. Certain things will forever remain conjecture, if not a mystery. And that is the real issue of this debate, IMO. Occam's razor is no more provable than anything else that science assumes, such as physical laws and even so-called constants (e.g. the cosmological constant) being immutable. That being the case, we are back to Descartes dilemma, to find the one premise that is absolutely certain. Time to revisit Goedel's ontological proof of God.

@@MrEricW2008 Funding is not that different in Europe from the US, it's just the source, that is different. Scientific Reseach generally gets funding from Governments, through the Horizon project, or private investment. It's also pretty well accepted in europe that 95% of scientist and the intelligencia don't believe in God, so there is no pretence. Unfortunately the intelligencia doesn't include the majority of politicians and rulemakers or the majority of people in general. As such there exists a whole raft of restrictions from an ethics committee which effectively bans certain areas of research. This seems to be not the case with the chinese for example who have no such restrictions and are currently one of the fastest growing nations in technology. Basing one's ethics and Laws on religious values isn't going to progress scientific discovery and human knowledge. Considering most of the earliest scientific discoveries and technological advances came from the middle east. Nothing has come from that region for 1400 years I leave you to decide why that is. As for Kaku. I think he is, or at least was, a great science communicator. Unfortunately he appears to have boarded the wrong boat "SS Stringtheory" is sailing in icy waters like the Titanic.

Without those restrictions, you can end up with a technological dystopian world. What differentiates the USA from Europe is the more than the ethical considerations. In Germany, Ph.ds are respected. In the USA, it's very divided based on state. Some states have high standards of education and produce well educated leaders. Other states....do not. Some states, maybe like Texas, occupy this strange middle ground. I think Kaku is appealing to the middle ground.

The interaction was great! Sabine is awesome, she has minimal belief, is consistent and complete, and probably questions her very fingers existence daily while Roger is very clever with large picture reasoning and has what are at least plausible areas of investigation for a better universal model. Michio is a bit out there with his confidence in extending a universal mathematical model - it’s like our universe is a building we’ve been in forever : Michio saying if we could simply stand outside we would see buildings forever, while roger is convinced it’s the same building just at different points in time while Sabine is saying the whole thing is pointless because no one’s going outside anytime soon.

Most uneducated people do. She is the Christopher Hitchens of Science. Making baseless attacks gets you attention and that is how she has made a living this past decade...attacking the very foundation of science...theories...where 100% of scientific advances comes from. A theory is unproven until it is, that does not mean it is not science. She herself has done nothing to advance science and has when she actually worked in the field, worked on other peoples ideas. She has created none herself. She is however a decent popular scientist and has a great channel when she explains known topics but she has a habit of backhanding theories as if an unproven one has no value. Its as if she does not understand where new ideas even come from or how knowledge is advanced.

Michio Kaku brings science to the masses and has a terrific education and work background. Why not just appreciate him for who he is? Why does this debate even matter? Michio can do whatever he wants. Sabine can do whatever she wants. However, Michio is just doing his usual simplified explanations while Roger disagrees, which is fine, and Sabine sounds a bit petty. If it's not jealously, then what is it with Sabine? Is Michio negatively impacting her in some way and she feels the need to put him in his place? And the host seems to be against the multiverse theory also which is odd for what I thought was a moderator. This whole interview was awkward and I can't understand its point. Oh well. Moving on.

I only recently discovered Sabine Hossenfelder, but I think she is brilliant... she explains things so well and introduces unnecessary uncertainty into things like the confidence with which Michio Kaku speaks: telling laymen to come up with "a better theory" (than string theory) for grand unification (which is not be even necessary, but just a "nice to have" ideal that appeals to the human mind) is to rather tell us to put up or shut up in nicer language with a bit of humor. This was really a rather convoluted discussion... it was never clear that the topic was a multiverse, but rather the legitimacy of string theory. Sabine has a whole video where she tears apart the modern state of particle physics, which is where string theory falls, and explains very well how it seems that particle physicists are trying to overcomplicate particle physics by making wild predictions above energies that we have been able to explore yet instead of simply applying Occam's razor and remaining with the simplest theory that fits the standard model. I find the idea of the multiverse quite fascinating and appealing, but it's just a hypothetical philosophical thought experiment for now, and may always be. Having Penrose there to propose another face to the argument was good, but I wish he had had the chance to speak more.

@NondescriptMammal Рік тому
That approach might be workable, if the original theory had some clear evidence to support its hypotheses, such that refining the theory to account for new data would make sense. But just dreaming up some theory that has no scientific basis and then changing it every time evidence appears that contradicts it, just seems like a bait and switch to make sure your books on the theory don't stop selling. Imagination clearly has a place even in science, if it leads you to something that actually relates to the reality that your theory is meant to explain. But imagination that only produces wild speculation shouldn't be conflated with science, as Sabine put it so well. And it can even damage the perceived integrity of science when this is the approach taken by someone who has scientific credentials and put the mark of their imprimatur on it.

There is something common here and that is the human element. After watching Oppenheimer the movie I came away thinking that there was a lot of politics and human weakness in the science community and if I were to start a business it would be good to focus it on a theory that could neither be proved or negated. You do not need a factory or employees to pump out theories and you can milk the human inclination to be trendy to rack up lecture events. Physical laws existed long before people so in this chain of events the most important thing to understand is human motivation. For me the multiverse and string theory look like "pet rock" stuff. We are like little kids that take it hard when we grow up and understand that we can not have every thing that we imagine. Yet imagine we must as a lot of things have to be looked at before something pans out and sticks around. Thank you, Roger and Sabine for your patience.

I think it's funny how Michio Kaku over dramatizes his discussions by adding too many catch phrases like, "and all of a sudden". Almost nothing in cosmology happens 'all of a sudden', and I'm pretty turned off by his approach to science communicating. Like Neil Tyson and his loud mouth and huge ego, I suspect that their lack of humility has scared plenty of common folk away from cosmology and science in general. Science to me has been life changing and humbling to the core of my being and has given me real spirituality that I could never get from philosophy or any religion. How we communicate science is as important as the science itself and there's no place in it for vanity or ego. I often wonder if Carl Sagan would cringe at the behavior of some of the people he mentored who seem to have forgotten how important humility is as a tool for communicating. Especially science.

Naysayers like Sabine supplement their income knocking ideas in their nascent stages, which are going to take more evidence to support. Einstein also doubted the concept of black holes, and he was wrong, partly because he, while brilliant, could not see past his own ideas. Science struggles to progress with regressive thinkers like Sabine, who harshly mocks these ideas yet has no alternative ideas of her own.

A fascinating discussion between some of the greatest minds currently engaged in some of the great questions of science and cosmology. The candidness with which the speakers can disagree with even some of the fundamental ideas of the others is matched only by the quality and breadth of the ideas which they propose. One thing which surprises me , however , is that no one even mentioned the most important principle which according to my understanding undergirds the the very reason why the multiverse theory was proposed in the first instance. I refer to the concepts surrounding the all-important idea of fine-tuning. This in my opinion is the most significant factor undergirding the very existence of the universe. Without going into some of the many examples of this, I will take for example the cosmological constant. It is estimated to be of the order of 10 to the power -122. Its exceeding smallness has baffled scientists for a very long time. This is so small it has no significant effect on structures that are less than a billion light years across. If it were not extremely small , stars and other astronomical structures would not be able to form. Another example is the inverse square law. If the law deviated from the perfect square by a mere 0.02, no planetary orbits would be stable . We could go on and on. The point is that the probabilities involved in the tuning of the constants is so enormously large that the numbers are far beyond anything which we can realistically relate to. The chances of you or I winning the national lottery is somewhere in the order of , say 50 million to one. The fine tuning of the combination (product of the probabilities) of the universal constants which we know about is many orders of magnitude greater. The only recourse for cosmologists who dismiss the idea of an infinite creator is to promote the wholly unprovable and mythical idea of a multiverse.

In a way, Kaku hijacked the conversation away from the proposed topic (as was constantly pointed out by Penrose). Kaku seems to believe that his version of string theory will eventually be proven to be that holy grail of physics: the theory of everything. But let's break down just one of his arguments: Democritus' atomic theory. Democritus believed the atom was the smallest possible unit of matter, indivisible (hence, atomos). But what have we shown over the past 2K years? Atoms exist, but most of the mass is concentrated in the nucleus with a cloud of electrons. Then we discovered nuclear fission: the nucleus is not an indivisible unit of matter either. But wait, there's more! It turns out protons and neutrons aren't indivisible either - they consist of quarks. What started with Democritus and Leucippus evolved into the Standard Model: 6 quarks, 6 leptons, 4 bosons, and a Higgs. Democritus wasn't wrong, but he wasn't exactly right either. If we're honest, science does have assumptions that are untestable: natural processes are governed by laws that can be expressed mathematically and that these laws are consistent across space and time. This assumption is baked into the scientific method in terms of reproducibility. But mathematics isn't reality - it's a model of reality that is useful to describe our experience. But as I've often said, I can create any arithmetically valid equation you like - but it may not be measuring what you think it does.
@GalaxyPedlar
@GalaxyPedlar Рік тому
I think you could still argue that an atom is indivisible because if you were to divide one, it would no longer act as the same atom. Eg, dividing a group of two neon atoms into two groups of one is a very different thing than fissioning a single neon atom.
