True, but there is a better way to understand this. Linde believes that Wheeler's intuition of the participatory nature of reality is probably right. To suggest that time cannot exist without matter or energy is not a particularly meaningful statement, GG, albeit a bloody obvious one. 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. It's not only the future that is still undetermined but the past as well. This is in contrast with classical objects, which can be described with ordinary numbers. Now imagine that there are two other large galaxies between Earth and the quasar. It exists all along… its position is just not describable by ordinary numbers. It had an observer - me. 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. This question demonstrates the dangers of trying to comprehend modern physics from popularizations. 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. During the course of the experiment, the radioactive uranium may or may not emit a particle. The other one did not want to give up. 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. 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. Get unlimited access when you subscribe. He sees the universe as a vast arena containing realms where the past is not yet fixed. You can say that the cat looks as if it were dead or as if it were alive during the whole week. In the absence of observers, our universe is dead. 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. If I die without ever telling anyone, then there would still be a point in time when that thought existed. Here Is Some Good Advice For Leaders Of Remote Teams. 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. 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? How Is Blackness Represented In Digital Domains? In this case the mica, not a conscious being, is the object that transforms what might happen into what does happen. Should We Build Its Replacement on the Moon? Why Is January 1 the Beginning of a New Year? Neither becomes real until someone opens the box and looks inside. This question originally appeared on Quora - the place to gain and share knowledge, empowering people to learn from others and better understand the world. From the quantum perspective the universe is an extremely interactive place. This in turn means that, without the observer, it does not even make sense to talk in terms of time and space. You may agree or disagree with his answers. How Can AI Support Small Businesses During The Pandemic? And what does the oracle of High Island himself think? 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. — is a good thing," Wootters says. The way one observer hears the sound or the way the other observer hears it? Instead of shying away from questions about the meaning of it all, Wheeler relishes the profoundand the paradoxical. And then all of a sudden, the sour cream was churned into butter. 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. First the spruce and white pine trees that cover High Island materialize from the fog, then the rocky headland, and finally the sea, as if the mere act of watching has drawn them all into existence. I only have a limited amount of time left, so I'll concentrate on one question: How come existence?'". By carefully arranging mirrors, they could make photons arriving from the routes around both galaxies strike a piece of photographic film simultaneously. 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. The measurements made now, says Wheeler, determine the photon's past. When that happens, one of those many different probable outcomes becomes real. The photons, in other words, act like particles. It is absolutely not true that states of matter do not exist when they are not noticed. If you are a Zinio, Nook, Kindle, Apple, or Google Play subscriber, you can enter your website access code to gain subscriber access. 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. — Our universe could have popped into existence 13.7 billion years ago without any divine help whatsoever, researchers say. 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.". If someone tells you this, he is talking nonsense. Simply put, it cannot be described by ordinary numbers. "The universe and the observer exist as a pair," Linde says. Why does the universe exist? John is interested in the significance of quantum measurement, how it creates an actuality of what was a mere potentiality. 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). A recording device cannot play the role of an observer, because who will read what is written on this recording device? At one point a loud bang interrupts our interview. Wheeler likes to use the example of a high-energy particle released by a radioactive element like radium in Earth's crust. "Will Wheeler's question— How come existence?— ever be answered? So you look at the sour cream and you think, 'There is no way I can do anything with that.' Most physicists nowadays would probably agree that all 'past, present and future' states of the universe exist at various points in spacetime. For the past two decades, though, he has pursued a far more provocative idea for an idea, something he calls genesis by observership. "I think asking this question — How come existence? 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.
