Dear Wilhelmus ,
Interesting comparison with Borges's "The library of Babel", and also the link you gave. Good luck with exploring the ocean of reality, and I am looking forward to hear more about your TS!

Dear Joseph Brenner,
Thank you for the comments. You consider that you are on the other side, but I can't see what this side is, given that I don't think I am on one side or another. Probably I will figure out your side from your essay. Anyway, I often take a neutral position and find myself interpreted as being "on the other side". When asked questions like "it from bit, or bit from it", I try to find a viewpoint that keeps the best from both. My habit of taking the position of going beyond dichotomies attracted me some years ago to read Stefan Lupascu's "Logique et contradiction" and "L'expérience microphysique et la pensée humaine".
You ask "what is the basis for saying that the universe asks us only questions with yes-no answers?"
What I actually said is that we ask questions to the universe, and the answers are yes/no:
"what we know about the universe comes in yes/no answers to our interrogations"
By interrogating the universe I meant perform observations and experiments. While the questions we have are more complex than those requiring yes/no answer, to get an answer from the universe, one has to frame them as yes/no questions. Of course, one can measure a position, and we will get a value of say x plus/minus an error, but this answer is just a more complex combination of yes/no answers: we never get the precise value of a continuous parameter, just an interval obtained by dividing the set of possible values.
"regarding the Tao as a model of It-Bit: the discussion of the Tao often refers not only to yang and yin, but to their conjunction (or join). How do you take this into account?"
This is precisely what I did in my essay, in which I argue that there is in fact an interplay between 'it' and 'bit'.
Best regards,
Cristi
Dear Michel,
You said "At least I am confident in this view and I think that quantum contextuality is a concept close to Wheeler's view but may be not as radical as the 'law without law' dogma. What is your opinion?"
I think my position is close to yours. I think that what the delayed choice experiment exhibits is contextuality, and one cannot directly infer "it from bit" and "law without law", which indeed are too radical. That's why I emphasize the interplay between information and ontology. I express this by the ideas of delayed choice initial conditions and global consistency.
I read your essay and I like it very much.
Best regards,
Cristi
Dear
Thank you for presenting your nice essay. I saw the abstract and will post my comments soon.
So you can produce material from your thinking. . . .
I am requesting you to go through my essay also. And I take this opportunity to say, to come to reality and base your arguments on experimental results.
I failed mainly because I worked against the main stream. The main stream community people want magic from science instead of realty especially in the subject of cosmology. We all know well that cosmology is a subject where speculations rule.
Hope to get your comments even directly to my mail ID also. . . .

Part of abstract:
- -Material objects are more fundamental- - is being proposed in this paper; It is well known that there is no mental experiment, which produced material. . . Similarly creation of matter from empty space as required in Steady State theory or in Bigbang is another such problem in the Cosmological counterpart. . . . In this paper we will see about CMB, how it is generated from stars and Galaxies around us. And here we show that NO Microwave background radiation was detected till now after excluding radiation from Stars and Galaxies. . . .

. . . . We should use our minds to down to earth realistic thinking. There is no point in wasting our brains in total imagination which are never realities. It is something like showing, mixing of cartoon characters with normal people in movies or people entering into Game-space in virtual reality games or Firing antimatter into a black hole!!!. It is sheer a madness of such concepts going on in many fields like science, mathematics, computer IT etc. . . .

"Material objects are more fundamental"..... in other words "IT from Bit" is true.

1. It is well known that there is no mental experiment, which produced material.
2. John Wheeler did not produce material from information.
3. Information describes material properties. But a mere description of material properties does not produce material.
4. There are Gods, Wizards, and Magicians, allegedly produced material from nowhere. But will that be a scientific experiment?

....And your question is like asking, -- which is first? Egg or Hen?-- in other words Matter is first or Information is first? Is that so? In reality there is no way that Matter comes from information.
Matter is another form of Energy. Matter cannot be created from nothing. Any type of vacuum cannot produce matter. Matter is another form of energy. Energy is having many forms: Mechanical, Electrical, Heat, Magnetic and so on..

.....Either way your abstract argument based empirical evidence is strong given that "a mere description of material properties does not produce material". While of course materials do give information.
I think you deserve a place in the final based on this alone. Concise - simple - but undeniable.
Dear snp
Thank you for visiting, and for sharing with me your thoughts.
You wrote
"So you can produce material from your thinking. . . ."
If by "material" you mean this essay, then you are right. If by "material" you refer to matter, then this is far from what I said, as I hope you will see if you will read my essay.
Best regards,
Cristi
You are Correct Cristi,
Thank you for such a nice discussion. I also mean to say one can not produce matter from thinking.
That's what I also said...

Dear Cristinel,
I congratulate you on your well written essay in which you have clearly pointed out the defects prevailing in Wheeler's views stemming from his delayed choice experiment.
But, your interpretation of Zero Axiom, I feel, is not right. Because you have said that according to Zero Axiom, the proposition p 'and' its negation -p is always true; that is in symbols it is written as (p&-p). But this is wrong, for (p&-p) is 'always' false. So you should say, (p v -p). This proposition is always true for whatever value you ascribe to 'p'. Hence, you better change the last sentence of your essay which reads "Assuming both propositions p and -p are true, we want to prove q. Since p is true, p v q is true. But since -p is true, p is false. From p v q and -p follows that q is true" to "From the proposition (-p or q) is true, we want to prove q. If p is true, q must be true and the whole proposition (-p v q) is true. But if q is false, p must be true"; where 'must' is logical.
In symbolic logic (-p or q) is written as p > q, meaning 'if p then q'.
[p > q, p, * q; p > q, -q, * p] where * means therefore.
Regarding this, please, consult a 'symbolic logician'.
Wishing you best of luck in the contest,
Sreenath
Dear Sreenath,
Thank you for reading my essay and for commenting.
There are two points with which I disagree in your comment.
First, while I interpreted the delayed choice experiment a bit different than Wheeler, I don't think I exposed any flaw in his view.
Regarding the part of your comment about the Zero Axiom. I agree, of course, that (p v -p) is true, and (p&p) is false (which I think is related to the principle of logical consistency I wrote about). But you are missing the whole point of my argument, contained in page 9. I think that if you will read it carefully (it's only half a page), you will understand what I meant. I will reproduce here only this: "We select, among the possible logical consequences of Axiom Zero, only a logically consistent subset".
Best regards,
Cristi
Hello Cristi,
Reading your essay was greatly enjoyed. When my essay posts; you will see there is broad agreement on the major points. However; my offering is philosophical and non-technical, while yours says some of the same things with precision. An excellent offering overall. I'll probably have more to say later.
All the Best,
Jonathan
Hello again,
I wanted to thank you for emphasizing in your essay that It from Bit comes out of the Participatory Universe idea, as a kind of outgrowth of the measurement process. This is something I emphasize the importance of in my own essay, but I did not fully grasp that some of the perspective I recommend was part of Wheeler's original conception of It from Bit Physics.
I think too many assume incorrectly that Wheeler was merely re-stating the digital or computing universe concept, when what he had in mind was probably a little different. I thank you for pointing out the historical relevance of Wheeler's work, and the caliber of his more successful students. Invariably; breaking new ground requires bold thinking, and JAW was certainly a champion of that.
Have Fun,
Jonathan
Hi Cristi,
If particles, particle properties (its) are both cause and effect of their interactions, of the exchange of information, of bits, then you cannot have one without the other. If particles, particle properties (its) only exist, are expressed and preserved in their interactions, in the exchange of bits, then the bits are no more fundamental than the 'its' so you cannot have one without the other.
The validity of the delayed choice experiment, whether or not you affect ''the'' past with an experiment depends on whether causality is a scientific proposition -which in my essay I argue it is not. If we understand something only if we can explain it as the effect of some cause and understand this cause only if we can explain it as the effect of a preceding cause and the chain of cause-and-effect either goes on ad infinitum or ends/starts with some primordial cause or event which, as it cannot be explained as the result from a preceding event, cannot be understood by definition, then causality ultimately cannot explain anything. If particles create, cause each other, then they explain each other in a circular way: here we can take any element of an explanation, start from any link of the chain of cause and effect to explain the next link and so on, to follow the circle back to the assumption we started with -which this time is explained by the foregoing reasoning. If we have to discard causality as it one way or the other implies that the universe has a primordial cause, that is, that it has been created by some outside intervention, then this has consequences for the interpretation of c, the 'speed' of light, and hence for what we mean with ''the'' past.
If there would be only a single charged particle in the entire universe, then it wouldn't be able to express its charge in interactions. Since it in that case it cannot be charged itself, charge, or any property, for that matter, must be something which is shared by particles, something which only exists, is expressed and preserved within their interactions. Similarly, in the seemingly innocuous assumption of Big Bang Cosmology (BBC) that we can regard the universe as an ordinary object which has particular properties as a whole, an object which changes in its entirety in time, we assume that there's something outside of it the universe interacts with, to which it owes its properties: that it has been created by some outside interference. The idea of causality, that cause precedes effect, only would make sense if we could determine where it is earlier and later, what precedes what in an absolute sense, if we could look from outside the universe in, which BBC, in the concept of cosmic time, wants to make us believe is justified even though we cannot actually step outside of it. To regard it as an object we may imagine to observe from without only would be justified if particles only would be the source, and not also the product of their interactions. The problem of the concept of cosmic time is that states that the universe lives in a time realm not of its own making: as in a Big Bang Universe (BBU) it is the same cosmic time everywhere (ignoring the effects of gravitational fields on the pace of clocks), here it takes light time to move, so here the speed of light indeed must be conceived of as the (finite) velocity of light.
In contrast, if a universe which creates itself out of nothing, without any outside intervention has to obey the conservation law according to which what comes out of nothing has to add to nothing, so as everything inside of it, including space and time has to cancel, it has no physical reality as a whole, doesn't exist as 'seen' from without, so to say, so unlike a BBU, a Self-Creating Universe (SCU) does not live in a time realm not of its own making. It doesn't make any sense to make statements about the content or state of a SCU from an imaginary observation post outside of it. Since a SCU contains and produces all time within, here an (inside) observer sees clocks running slower as they are more distant even when at rest relative to the observer, so here it is not the same time everywhere: the concept of cosmic time has no significance in a SCU whatsoever. As a result, here a photon bridges any spacetime distance (emphasis on 'time') in no time at all. As in a SCU every observer, no matter when he lives or where he looks from sees clocks run slower as they are more distant, here it doesn't even make sense to ask what precedes what, where it is earlier and where it is later in an absolute sense: in a SCU everything is relative. As a result, the observer doesn't see a distant galaxy as it was in a distant past, in ''the'' past, but as it is at present, to him, never mind that the galaxy looks different to a near observer. The problem of the concept of ''the'' past is that it presupposes the existence of an objectively observable reality at the origin of our observations, that is, that it is scientifically legitimate to imagine to look at the universe from without, which, as said, only would be justified if particles only would be the source of forces, interactions, and not also their product.
To be continued in the next post.
So the delayed experiment doesn't change the past, nor can it be seen as ''switching in the last moment the web with another kind, while the insect is still heading toward the web'': if with ''insect'' we mean a photon, then it arrives at the web the moment the web is 'switched' on.
If atom A emits a photon which is absorbed by B, a transmission which changes the state of both atoms (and hence affects all particles within their interaction horizons), then A 'sees' B change at the time it emits the photon, as soon as A changes itself so sees a slightly changed world, whereas B 'sees' A change at the time it absorbs the photon, as it changes itself and hence the world it observes. That is, unless we believe that B, after absorbing the photon sends back a message to confirm the receipt of the photon, a thank-you-note informing A that it can, as of this moment, the receipt of the note, start to see B in its new state. While BBC assumes that the emission of the photon by A precedes its absorption by B in cosmic time, in a SCU both A and B are equally right about the time of the transmission, in which case its transmission must be instantaneous. The fact that we cannot experimentally determine whether c must be conceived of as a (finite) velocity of light or as a property of spacetime (a number which says how many kilometer pace distance correspond to one second time distance), combined with the fact that an instantaneous action-at-a-distance would solve most if not all riddles of quantum mechanics like entanglement, the EPR paradox and the double-slit experiment should at least give pause for thought.

Dear Jonathan,
I want to thank you for reading and commenting my essay. Indeed, too often some ideas propagate in a distorted or misunderstood form, and few have time to go to the source and check with careful consideration. I guess the problem is that there are so many interesting things to do and read in life. This competition is a good opportunity to go back and (re)read some of Wheeler's works. I am glad if I could shed a little more light on the subject. I am looking forward for your essay.
Best regards,
Cristi Stoica
Dear Anton,
I appreciate you posted here such interesting comments, which present a critical view on causality. I think causality has its roots more in our daily experience, and in classical mechanics. This is so rooted in our minds. Theory of relativity and quantum mechanics, were so difficult to understand, hence were initially resisted, mostly because of our preconceptions about causality. Wheeler's delayed choice experiment was intended to show that causality is not what it used to be, so to speak. This doesn't mean that delayed choice experiment shows or claims to show that we can change the past, this occurs only because we assume that the past was in a state, which was then modified, as in the grandfather paradox. "No phenomenon is a phenomenon until it is an observed phenomenon."
Evolution equations are local, and the solutions exhibit local causality, which seems to be violated by quantum mechanics. I proposed that the "global consistency principle" explains this, by constraining local causality so that, globally, there is no conflict. So, global consistency comes first, and local causality later. Local causality is just an illusion of an observer who perceives time as flowing. In the block universe, in which time is just the fourth dimension, as in relativity, global consistency is natural, and local causality emerges only when you go to a dynamical description, in terms of a flowing time. When you tell a 4d story, things look natural, but when you tell it as a 3d story evolving in time, causality becomes manifest, and then appears to be broken by quantum nonlocality and delayed chocie experiments, and we conclude that there are paradoxes. But this is an illusion.
Best regards,
Cristi
