These small words — it looks like it was here— for practical purposes it may not matter much, but for me as a human being, I do not know any sense in which I could claim that the universe is here in the absence of observers. Wheeler points to the example of Charles Darwin in the 19th century and how he provided a simple explanation — evolution through natural selection — for what seemed an utterly intractable problem: how to explain the origin and diversity of life on Earth. Such a pattern could be produced only if the photons are behaving like waves, with each individual photon spreading out and surging against both slits at once, like a breaker hitting a jetty. Does this mean humans are necessary to the existence of the universe? But, there is a branch of physics that looks at the question of whether any thing or event can exist without an observer. The Universe is not Observer-Dependent And this is the final part we have arrived at concerning my view on consciousness and possibilities in the realm of physics concerning it. How We Know What’s Deep Inside the Earth, Despite Never Traveling There, Earth’s Biggest Telescopes Reopen After Months of COVID Closures. And that may indeed be the case. At one point a loud bang interrupts our interview. The only universe you have ever experienced is the shadow of the real one projected onto your mind. It's a tenuous lead, a clue that the mystery of creation may lie not in the distant past but in the living present. "This point of view is what gives me hope that the question — How come existence? I only have a limited amount of time left, so I'll concentrate on one question: How come existence?'". It is absolutely not true that states of matter do not exist when they are not noticed. Where Is There Still Room For Growth When It Comes To Content Creation? Want it all? For instance, the carbon atoms in your body are "fossils" created in the heart of exploding supernova stars. Arecibo is Dead. "Why is a trickier thing." "One revolution of our galaxy.". If someone tells you this, he is talking nonsense. You can follow Quora on Twitter, Facebook, and Google+. The correct statement is that a quantum system usually exists in a state that is not at all like the states of the classical world. But when the photon detectors are removed, something weird occurs. The particle, as with the photons in the two-slit experiment, exists in many possible states at once, traveling in every possible direction, not quite real and solid until it interacts with something, say a piece of mica in Earth's crust. "Why not see how far you can stretch? Wheeler has come up with a cosmic-scale version of this experiment that has even weirder implications. Save up to 70% off the cover price when you subscribe to Discover magazine. Bottom line: reality begins and ends with the observer. And in the sweep of evolution, I doubt that we're the last word in intelligence. Does unitarity of the evolution of wavefunction get rid of the need for a "conscious observer", and does collapse in contrast demand a "conscious observer"? That experiment is exceedingly strange in its own right, even without Wheeler's extra kink thrown in. How Do Employee Needs Vary From Generation To Generation? Why Is January 1 the Beginning of a New Year? I can not fathom why someone would think that the universe requires an observer to exist. This question originally appeared on Quora - the place to gain and share knowledge, empowering people to learn from others and better understand the world. He has come to think of that as the essential building block of reality.". But sometimes, unexpected things happen. Why Is The Future Of Business About Creating A Shared Value For Everyone? Our observations, he suggests, might actually contribute to the creation of physical reality. When the electron finally arrives at the screen, the screen (a classical object) measures the electron’s position: the electron is now in a “position eigenstate”. And my answer would be that the universe looks as if it existed before I started looking at it. Let me explain this through a common thought experiment: the infamous two-slit experiment. Most physicists nowadays would probably agree that all 'past, present and future' states of the universe exist at various points in spacetime. Wheeler's hunch is that the universe is built like an enormous feedback loop, a loop in which we contribute to the ongoing creation of not just the present and the future but the past as well. Should We Build Its Replacement on the Moon? The experiment can be run two ways: with photon detectors right beside each slit that allow physicists to observe the photons as they pass, or with detectors removed, which allows the photons to travel unobserved. Using a light source and an arrangement of mirrors to provide a number of possible photon routes, the physicists were able to show that the paths the photons took were not fixed until the physicists made their measurements, even though those measurements were made after the photons had already left the light source and begun their circuit through the course of mirrors. There might be higher levels later. En route, however, the electron is not in a position eigenstate. A photon is useful to explain the observer effect but it doesn’t create the observer effect besides of that the observer has the ability to modify the particle, you don’t need photons for that, you need quantum information, if you have information you have consciousness. Why does the universe exist? But the very fact that he asks these questions, and suggests some plausible — and implausible — answers, it has shaken these boundaries of what is possible and what is impossible to ask.". While this misty genesis unfolds, the island's most eminent residentdiscusses notions that still perplex him after seven decades in physics, including his gut feeling that the very universe may be constantly emerging from a haze of possibility, that we inhabit a cosmos made real in part by our own observations. The double slit experiment would indicate that there was nothing, without conscious man to observe it. I would say consciousness is outside the realm of physical matter and exists independently of it (which can give rise to something observing the beginning of the universe). The other one did not want to give up. The correct statement is that a quantum system usually exists in a state that is not at all like the states of the classical world. Existence does exist--with or without an observer. When you open the cat's box after a week, you're going to find either a live cat or a smelly piece of meat. When physicists use the photon detectors, the result is unsurprising: Every photon is observed to pass through one slit or the other. For with unitarity there are is no requirement for such an observer, and collapse can't be explained without such an observer. During the course of the experiment, the radioactive uranium may or may not emit a particle. The observer simultaneously plays a part in creating the reality he is observing. Wheeler is gracious to a fault; one colleague describes him as "a gentleman hidden inside a gentleman." You may agree or disagree with his answers. John is interested in the significance of quantum measurement, how it creates an actuality of what was a mere potentiality. However, in these systems, all the quantum behavior is averaged out, so to speak, so their behavior is indistinguishable from that of classical systems. Wheeler conjectures we are part of a universe that is a work in progress; we are tiny patches of the universe looking at itself — and building itself. It illustrates a key principle of quantum mechanics: Light has a dual nature. originally appeared on Quora: the place to gain and share knowledge, empowering people to learn from others and better understand the world. Why Should Leaders Stop Obsessing About Platforms And Ecosystems? There was absolutely no way it could change anything, but it just kept kicking and kicking and kicking. This is precisely what happens when a quantum system interacts with a classical system; i.e., when we “measure” something. The gravity from massive objects like galaxies can bend light, just as conventional glass lenses do. All Rights Reserved, This is a BETA experience. What Impact Is Technology Having On Today’s Workforce? In this case the mica, not a conscious being, is the object that transforms what might happen into what does happen. So why should we think we're at the point where we can understand everything? Something cannot be of different colors, smells or sounds at the same time. Put a cat in a closed box, along with a vial of poison gas, a piece of uranium, and a Geiger counter hooked up to a hammer suspended above the gas vial. EY & Citi On The Importance Of Resilience And Innovation, Impact 50: Investors Seeking Profit — And Pushing For Change, Three Things You’ll Need Before Starting A New Business. Remove the observer, what sound or smell continues to exist. He was an early advocate of the anthropic principle, the idea that the universe and the laws of physics are fine-tuned to permit the existence of life. Here's the odd part. With that observation, an entire consistent sequence of events— the particle jettisoned from the uranium, the release of the poison gas, the cat's death— at once becomes real, giving the appearance of something that has taken weeks to transpire. "You can say that the universe is there only when there is an observer who can say, Yes, I see the universe there. Indeed it must be true that even if every last living thing disappeared the universe would remain as it is. If someone tells you this, he is talking nonsense. And what does the oracle of High Island himself think? It had an observer - me. To Wheeler we are not simply bystanders on a cosmic stage; we are shapers and creators living in a participatory universe. Scientists say nothing definate ever happens outside of our observation and that without an observer only random possibilities exist. Quantum physics involves a trade off between time and energy - something that lasts a long time must have little energy and vice versa. If the particle is not released, the cat will live. Get unlimited access when you subscribe. Suppose that on Earth, some astronomers decide to observe the quasars. If you are a Zinio, Nook, Kindle, Apple, or Google Play subscriber, you can enter your website access code to gain subscriber access. "You know, if you say that we're smart enough to figure everything out, that is a very arrogant thought. And by peering back into time, even all the way back to the Big Bang, our present observations select one out of many possible quantum histories for the universe. And we see only a tiny portion of that cosmos. Likewise, when we look at the universe, the best we can say is that it looks as if it were there 10 billion years ago.". (Quora discussion) Does an odour continue to exist the way one observer smells it or the way another smells it? We all learned from people like John Wheeler, who asks strange questions and gives strange answers. "We don't expect dogs or ants to be able to figure out everything about the universe. The universe could probably exist without an observer, but for this existence to mean something there would have to be an observer who is conscious of it. Neither becomes real until someone opens the box and looks inside. The experiment involves an electron gun that emits electrons which can go through one of two slits before impacting a screen. Alternating light and dark bands would appear on the film, identical to the pattern found when photons passed through the two slits. It's not even really a theory but more of an intuition about what a final theory of everything might be like. One would expect to see two distinct clusters of dots on the film, corresponding to where individual photons hit after randomly passing through one slit or theother. It is absolutely not true that states of matter do not exist when they are not noticed. To suggest that time cannot exist without matter or energy is not a particularly meaningful statement, GG, albeit a bloody obvious one. You can say that the cat looks as if it were dead or as if it were alive during the whole week. In 1984 physicists at the University of Maryland set up a tabletop version of the delayed-choice scenario. He drowned in sour cream. And that's not all. Schrödinger asked, What could be known about the cat before opening the box? He is one of the last of the towering figures of 20th-century physics, a member of the generation that plumbed the mysteries of quantum mechanics and limned the utmost reaches of space and time. But he differs with Wheeler on one crucial point. There was nothing solid there; they could not jump from the can. If someone tells you this, he is talking nonsense. When a quantum system is (briefly) in such a classical state, it is said to be in an eigenstate (“eigen” means “own” in German); the value of the property would be the corresponding “eigenvalue”. Wheeler is the first to admit that this is a mind-stretching idea. In the experiment, light — a stream of photons — shines through two parallel slits and hits a strip of photographic film behind the slits. When that happens, one of those many different probable outcomes becomes real. It's not only the future that is still undetermined but the past as well. Yes, if I have a thought it exists - even if I never tell anyone about it. We are together, the universe and us. To demonstrate, he sketches a diagram on a scrap of paper. consciousness in … In order for us to see that something happens, and say to one another that something happens, you need to have a universe, you need to have a recording device, and you need to have us. Do most modern physicists think life after death exists. Opinions expressed by Forbes Contributors are their own. Alternatively, they retroactively force the photon onto one straight trail toward their detector, even though the photon began its jaunt long before any detectors existed. Wheeler suspects that most of the universe consists of huge clouds of uncertainty that have not yet interacted either with a conscious observer or even with some lump of inanimate matter. The measurements made now, says Wheeler, determine the photon's past. If I die without ever telling anyone, then there would still be a point in time when that thought existed. The act of observing is not a requirement of existence. And many things in this universe are in eigenstates every once in a while simply because of the way they interact with other things which are, for all practical intents and purposes, classical. An astronomer verifies it this way: “The universe brought forth life in order to exist; the very cosmos does not exist unless observed”. Geiger counter) detects radioactivity (i.e. Ordinary matter and radiation play the dominant roles. Wheeler is short and sturdily built, with sparse white hair. These small words — it looks like it was here— for practical purposes it may not matter much, but for me as a human being, I do not know any sense in which I could claim that the universe is here in the absence of observers. Sometimes light behaves like a compact particle, a photon; sometimes it seems to behave like a wave spread out in space, just like the ripples in a pond. Your website access code is located in the upper right corner of the Table of Contents page of your digital edition. Wheeler's son, who lives on a cliff a few hundred yards away, has fired a small cannon, a gift from Wheeler. Does Wheeler think that physicists might one day have a similarly clear understanding of the origin of the universe? The fluorescent screen has no consciousness at all, but it does confine the electron to an eigenstate because it itself is a classical object (or so close to being classical as to be indistinguishable from it). "That's the same Schrödinger cat question. Every once in a while, some properties of a quantum system may be describable by ordinary numbers. A physicist's observations determine whether an atom, say, behaves like a fluid wave or a hard particle, or which path it follows in traveling from one point to another. During the interaction, the quantum system is confined to an eigenstate. Simply put, it cannot be described by ordinary numbers. How Can AI Support Small Businesses During The Pandemic? One outcome includes a dead cat; another, a live one. We find that an interference pattern emerges on the screen; this is true even when we fire the electrons one at a time. It's necessary for somebody to look at it. The observer effect is way more complicated than that. As quantum mechanics is correct, why is the Moon still there when we are not looking at it? He just died. William Wootters, one of Wheeler's many students and now a professor of physics at Williams College in Williamstown, Massachusetts, sees Wheeler as an almost oracular figure. — was meaningless did not stop us from asking it. The photons, in other words, act like particles. Answer by Viktor T. Toth, IT pro, part-time physicist, on Quora: If quantum physics states matter doesn't exist when it's not being noticed, then, without life, would the universe cease to exist? The entire universe can be defined in terms of matter or energy so all you're saying is that if the universe did not exist then time would not exist. But it does not mean the electron’s existence is conditional. Science does not know if there was any universe before conscious man, Adam, opened his eyes to look at it. You may opt-out by. I come from Russia, where there is a fairy tale about two frogs in a can of sour cream. ", "I had a heart attack on January 9, 2001," he says, "I said, 'That's a signal. Your email address is used to log in and will not be shared or sold. It does not have a position in the classical sense at all. The Heisenberg Uncertainty Principle of consciousness states that no pure measurement is possible without creation. If quantum physics states matter doesn't exist when it's not being noticed, then, without life, would the universe cease to exist? By the time the astronomers decide which measurement to make — whether to pin down the photon to one definite route or to have it follow both paths simultaneously — the photon could have already journeyed for billions of years, long before life appeared on Earth. One of the more important tenets of Quantum Physics is that “nothing can exist without an observer, the human consciousness”. Conspiratorial cosmology – the case against the Universe (Jörg P. Rachen, Ute G. Gahlings, Cornell University Library Archive) Is 'reality' unreal? So yes, it goes through both slits and does many other things that classical objects just cannot do (and it is wrong even to try to visualize the electron when it is in this quantum state). Wheeler takes the quantum view and runs with it. Physicists who deal in quantum mechanics state: “You cannot (objectively) observe something without changing it in the process.” It's got to generate at least some good ideas, even if the question doesn't get answered. This is according a famous theory in quantum mechanics which argues that a particle's past behaviour changes based on what we see. You need an observer who looks at the universe. I cannot imagine a consistent theory of everything that ignores consciousness. True, but there is a better way to understand this. It would be tempting to dismiss Wheeler's thought experiment as a curious idea, except for one thing: It has been demonstrated in a laboratory. How Can Tech Companies Become More Human Focused? In Wheeler's experiment the two huge galaxies substitute for the pair of slits; the quasar is the light source. The universe doesn't exist if we stop looking at it. In this case a telescope plays the role of the photon detector in the two-slit experiment. Linde believes that conscious observers are an essential component of the universe and cannot be replaced by inanimate objects. See where that takes you. Instead of shying away from questions about the meaning of it all, Wheeler relishes the profoundand the paradoxical. At every moment, in Wheeler's view, the entire universe is filled with such events, where the possible outcomes of countless interactions become real, where the infinite variety inherent in quantum mechanics manifests as a physical cosmos. If an internal monitor (e.g. To illustrate his idea, he devised what he calls his "delayed-choice experiment," which adds a startling, cosmic variation to a cornerstone of quantum physics: the classic two-slit experiment. "I'm happy that some people who previously thought this question — How come existence? If there were no such thing as quantum mechanics, the answer would be simple: The cat is either alive or dead, depending on whether a particle hit the Geiger counter. If the astronomers point a telescope in the direction of one of the two intervening galaxies, they will see photons from the quasar that were deflected by that galaxy; they would get the same result by looking at the other galaxy. And then all of a sudden, the sour cream was churned into butter. It is absolutely not true that states of matter do not exist when they are not noticed. Wheeler likes to use the example of a high-energy particle released by a radioactive element like radium in Earth's crust. So no, the existence of the universe does not depend on the presence of life. Wootters is skeptical. Instead, a pattern of alternating light and dark stripes appears. It exists all along… its position is just not describable by ordinary numbers. The trail of disrupted atoms left in the mica by the high-energy particle becomes part of the real world. "We are participators," Wheeler said "in bringing about something of the universe in the distant past." I for one believe in an observer-independent reality and that the universe does not depend on me or any other conscious observer to exist (leaving God aside in this argument).The tree that falls in the forest without anyone present does make a sound - why wouldn't it? — can be answered," he says. The frogs were drowning in the cream. You may have heard that this means that every single electron goes through both slits. Then the frog stood on the butter and jumped out of the can. In fact, the Copenhagen interpretation contains no such requirement. He sits with his back to a wide window. "You may ask whether the universe really existed before you start looking at it," he says. By carefully arranging mirrors, they could make photons arriving from the routes around both galaxies strike a piece of photographic film simultaneously. Instead, what would happen according to quantum physics is that the universe could exist as a superposition of states, unfolding simultaneously in every possible permutation, until such a time when an observer springs up in one such possible universe. That is to say, their position, their velocity, and other physical properties can be described using simple numerical values. On an end table near the sofa rests a large oval rock, with one half polished black so that its surface resembles the Chinese yin-yang symbol. © 2021 Forbes Media LLC. This in turn means that, without the observer, it does not even make sense to talk in terms of time and space. Will we ever understand why the universe came into being? Sign up for our email newsletter for the latest science news. Fossils are really no different than anything else in nature. Yes, I've heard of quantum mechanics. The Big Bang is still a theory, so why is everyone so certain of the age of the universe? — Our universe could have popped into existence 13.7 billion years ago without any divine help whatsoever, researchers say. This is in contrast with classical objects, which can be described with ordinary numbers. But the results of the experiment wouldn't change. In the absence of observers, our universe is dead. "Or at least how," he says. But that courtly demeanor also hides something else: one of the most adventurous minds in physics. One of the frogs understood there was no hope, and he stopped beating the sour cream with his legs. At the same time I think it's great to ask the question and see how far you can go before you bump into awall.". So you look at the sour cream and you think, 'There is no way I can do anything with that.' It is constructed of what is called qualia, or the subjective conscious experience - that which you experience but which has no external existence. While conscious observers certainly partake in the creation of the participatory universe envisioned by Wheeler, they are not the only, or even primary, way by which quantum potentials become real. Just as in the two-slit experiment, light — photons — from the quasar can follow two different paths, past one galaxy or the other. The question from the human perspective should be "Does the conscious observer needs a universe to exist?" So,the answer is clear :no time and distances can ever exist in an empty universe,which itself couldn’t be called this way any longer,owing its name to the presence of material objects in it. But if the physicists remove the detectors, each photon seems to travel both routes simultaneously like a tiny wave, producing the striped pattern. The way one observer hears the sound or the way the other observer hears it? For the past two decades, though, he has pursued a far more provocative idea for an idea, something he calls genesis by observership. The outcome of the experiment depends on what the physicists try to measure: If they set up detectors beside the slits, the photons act like ordinary particles, always traversing one route or the other, not both at the same time. Here Is Some Good Advice For Leaders Of Remote Teams. Linde believes that Wheeler's intuition of the participatory nature of reality is probably right. In his concern for the nature of quantum measurements, Wheeler is addressing one of the most confounding aspects of modern physics: the relationship between the observations and the outcomes of experiments on quantum systems. Scientists don't say that. — is a good thing," Wootters says. "That rock is about 200 million yearsold," says Wheeler. After a lifetime of fundamental contributions in fields ranging from atomic physics to cosmology, Wheeler has concerned himself in his later years with what he calls "ideas for ideas. Now it is true that there is no such thing as a truly classical object: that even people, cats, cannonballs or planets are made of a large number of quantum particles. We know, from God, that there was a universe at least five days, before man was created to look at it. But in the quantum world, things are not so straightforward. Read our privacy policy. This question demonstrates the dangers of trying to comprehend modern physics from popularizations. How Is Blackness Represented In Digital Domains? "The universe and the observer exist as a pair," Linde says. At the quantum level, reality does not exist if you are not interacting with it.” Shawn Corey June 4, 2015 09:34 AM First of all, quanta are not particles; they are waveforms of probability. "The universe and the observer exist as a pair," Linde says. Although Wheeler's face looks careworn and sober, it becomes almost boyish when he smiles, as he does when I extend a hand to help him from the couch and he says, "Ah, antigravity." Stanford University physicist Andrei Linde believes this quantum paradox gets to the heart of Wheeler's idea about the nature of the universe: The principles of quantum mechanics dictate severe limits on the certainty of our knowledge. Outside, the fog is beginning to lift on what promises to be a hot summer day. However, what is interesting is the nature of that existence (the external observable reality )and how it is … Is the Multiverse Theory Science Fiction or Science Fact? But the astronomers could also mimic the second part of the two-slit experiment. When physicists look at the basic constituents of reality— atoms and their innards, or the particles of light called photons— what they see depends on how they have set up their experiment. Simply put, it cannot be described by ordinary numbers. The boundary between an objective "world out there" and our own subjective consciousness that seemed so clearly defined in physics before the eerie discoveries of the 20th century blurs in quantum mechanics. In one case the astronomers create a past in which a photon took both possible routes from the quasar to Earth. The quasar could be very distant from Earth, with light so faint that its photons hit the piece of film only one at a time. Now imagine that there are two other large galaxies between Earth and the quasar. The world seems to be putting itself together piece by piece on this damp gray morning along the coast of Maine. Alternating bright stripes in the pattern on the film show where crests from those waves overlap; dark stripes indicate that a crest and a trough have canceled each other. In that case the striped pattern doesn't appear on the film. Scientists work on a way to find out (Joel N. Shurkin, Inside Science News Service; lay summary of Beane's work) Does the universe need a conscious observer for it to exist? Nor is there any need for consciousness to be involved.
