Dear Readers,

There are three kinds of essays in our contest: 1) the essays with original physics research where all physics' information was created by their authors. Often such papers contain some errors or unclear propositions because it is very difficult to create a NEW physical theory (information). 2) There are essays-stories about physics which contain physics' information copied from the physics' textbooks or papers (for example authors Jarmo Makela, Singh, Durham, Funakoshi and so on). The author's commentaries like ''this theory is good, or not'' is neither original physics research nor new physics' research. These essays-stories cannot have any errors by definition because all physics' information was copied from the textbooks and other papers. 3) There are essays of mixed type containing mixed information (original research physics' information copied from the textbooks and papers). It is clear that the authors of the essays-stories have advantages because their essays never contain errors since all Physics' information was copied from the textbooks or other published papers. However, it does not mean these essays-stories are better than essays with original research.

What kind of the essay must FQXi community support? If we support the essays-stories then we'll transform FQXi community into the entertainment community. For example, instead of my ''interpretation of quantum mechanics'' I could send the anecdotes about Bohr, Einstein or stories like Gamov's ''Mr.Tompkins in paperback''. It would be very interesting and fun. Another option is to create essays-discussions with Einstein, Bohr, or Aristotle following the example of Jarmo Makela. In this context, the next logical step is to organize a banquet for the authors of essays where we tell jokes and funny stories about physics. What is Our Purpose?

However, since the goals of the FQXi (the "Contest") are to: Encourage and support rigorous, innovative, and influential thinking about foundational questions in physics and cosmology; Identify and reward top thinkers in foundational questions, therefore I ask readers to vote for essays with original physics research rather than for essays-stories even if the first may contain some unclear information. In this way we'll encourage the fundamental physics research but not entertainment essays.

Sincerely,

Constantin

    Dear Anton,

    I believe we have made much progress in understanding each others positions, and I think we are much closer in agreement than I first thought, although we still have our differences.

    You wrote: "so if with cosmic time you mean the time since the bang, then you've lost me."

    Dear Anton,

    I believe we have made much progress in understanding each others positions, and I think we are much closer in agreement than I first thought, although we still have our differences.

    You wrote: "so if with cosmic time you mean the time since the bang, then you've lost me."

    No, cosmic time only means that all mass-energy, all spacetime, everything that we define as the universe expands and evolves together, regardless of time dilation differences due to motion or gravity, (i.e.regardless of local time).

    You quoted me: "the mass-energy that was lost to BH's is eventually recovered in the new cycle"

    This is poor wording by me. By "mass-energy that was lost", I don't mean that it was actually destroyed. As you stated, the mass of the BH increases. Agreed. More about this later, because BHs are the key to my model.

    You wrote: "Though the effect of this expansion is small at the scale of stars and even galaxies, it is observable in the motion of clusters of galaxies with respect to each other, in the continuous creation of spacetime between them."

    Agreed.

    You wrote: "... the expansion of the universe doesn't decelerate under the influence of gravity as the bigbang scenario predicts, but keeps accelerating."

    Agreed

    You wrote: "So to me terms like 'black/white hole', 'dark energy/matter' and 'singularities' belong to the language of fairy tales, not physics."

    If you want to be taken seriously, IMO you must work within the incorrect paradigm, with the given terminology, and explain why your theory/model/paradigm is better than the status quo. The burden is on us to convince those who accept the Standard Model that a better model exits. My understanding of the 'black/white hole', 'dark energy/matter' and 'singularities' is different the Standard Model, but I'm going to rejected, without any consideration, if I refer to them as "fairy tales, not physics".

    Let's return to BHs, because they are fundamental. This how I explained it to a friend on the "time travelers" blog: "What do you think the expansion of the universe is? It's a form of anti-gravity. Gravity is not the major influence on the universe on the large scale, expansion is. Think in terms of your frequency shifted photons, how long does it take for them to cross the event horizon for a observer outside of the BH's sphere of influence? It takes until the end of the universe! Now, if the universe is undergoing an accelerated expansion, what is happening to the frequency of the photons that are waiting to cross the event horizon for a observer outside of the BH's sphere of influence? The photons are having their frequency shifted in opposition to the gravity of the BH! If you wait long enough BH's will no longer be perfect sinks, but perfect sources, that is until they receive the feedback from other BHs (that are in the same state) which will transition them all back once again to perfect sinks. This is the mechanism for a eternally expanding cyclical universe."

    As for what I refer to as the singularity, it is a time in the history of the universe, when viewed from a long distance, therefore in the extreme distant future, the universe (if we were able to observe it at its most distant past), appears point-like. It never was a point in the mathematical sense (as in the BBT), it would only appear point-like compared to the vastly expanded universe we presently inhabit. This has a very different meaning than that of the BBT.

    You wrote: "As to the CMB, this indeed is no fossil, remnant radiation but is produced at present (see UPDATE 2)"

    I'm sure I will have to disagree with you on this, but before I respond I will read your update.

    Finally, you admitted: "I admit that I haven't understood your essay completely because my knowledge of GR is very limited."

    Even the experts have difficultly with the mathematics of Einstein's Equations, because they are very difficult to solve and obtain exact solutions! That doesn't mean that you can't learn the concepts of GR and then use them against those who prefer the status quo. Those of us who would like to see the Standard Model replaced could always use another ally, but as I stated previously, IMO you won't be taken seriously, unless you work within the incorrect paradigm to change it.

    Costantin,

    I would say that I completely agree. I admit to enjoying the essays of which you are referring, but I haven't rated any essays yet, because I wanted to read them all, which is quite a chore, and then determine the "most qualified" to get the highest scores. Since reading all of the essays is so time consuming, I'll wager that a good number of the community hasn't and won't read them. So is the community rating system appropriate since an essay needs to be within the top 35 to be presented to the judges? Many of the essays that provide fundamentally novel ideas are typically more difficult to fully understand than with just "a brief look". Thank you for helping me determine which essays deserve the best scores. I only hope that those in the community that haven't rated essays yet will read your comments before doing so.

    Best Regards,

    Dan

    Dear Anton,

    Probably you mean the ''Black Holes'' by the word ''holes'', since I don't found any mention about my vacuum holes in your thread. There is a considerable difference between the orthodox notion of the Black Holes and my vacuum holes.

    You wrote in this post ''the speed of light isn't a velocity but rather a property of spacetime''.

    By definition, the velocity is the rate and direction of the change in the position of an object. For example, since light travels a distance ct during the time t, it is in agreement with the definition of the velocity.

    I can add another flaw in the Black Hole theory: according to the theory, the magnetic field is caused by the exchange of virtual photons. Since the light (virtual photons) cannot escape from a black hole, therefore the Black Holes cannot have the magnetic fields.

    Sincerely,

    Constantin

    Dear Leshan,

    ''By definition, the velocity is the rate and direction of the change in the position of an object. For example, since light travels a distance ct during the time t, it is in agreement with the definition of the velocity.''

    We can only speak about the velocity of an object with respect to objects if and when it interacts with them as it moves. Since the photon has no mass or charge, it cannot express its presence to the objects with respect to which it is supposed to move: having no mass, it cannot have a position. If it doesn't interact, exist to these objects nor the environment to the photon, then it makes no sense to speak about its velocity as there's nothing with respect to which it moves. This is why to the photon itself its transmission is instantaneous: it bridges a spacetime distance in no time at all even though an observer measures a time equal to that space distance. (All interactions the photon is supposed to be involved in as travels, all Feynman diagrams of all possible interactions with virtual electrons, positrons and photons, are actually taken care off at the photon source and receiver.) The idea of a photon as some kind of bullet buzzing from a light source to some random target across spacetime is a classical notion of what in actually is a purely quantum mechanic phenomenon. Since we assume that the universe evolves as a whole with respect to some clock outside of it, we assume the emission of the photon to (causally) precede its absorption elsewhere, according to that clock.

    If particle A emits a photon which is absorbed by B, a transmission changing the state of both A and B, then A sees the state of B change at the time it emits the photon, whereas B sees the state of A change as it absorbs the photon. (That is, unless B after absorbing the photon sends back a message to A to confirm the receipt of the photon, a thank-you-note saying that A can from this moment start to see B in its new state). Whereas according to A and B the transmission is instantaneous, having no mass, to the photon there's no space nor time distance between A and B so to the photon its transmission also is instantaneous. Since to a massive observer A and B are separated in space and thus in time, he measures a transmission time equal to their distance. So if there's no time, no clock outside the universe to determine what in an absolute sense precedes what, then we cannot say that either A or B is the cause of the transmission, which is a requisite to be able to speak about a velocity. We can, therefore, only speak about a velocity if it is smaller than c. The difference is that at velocities < c, a bullet may miss the intended target, whereas at the 'speed' of light, the bullet only can be shot if and when it hits the target. For a photon to be emitted, transmitted requires the cooperation of the receiver, so quantum mechanics at heart is non-causal, which is why it seems so strange. The flaw of causality, however, is that if we understand something only if we can reduce it to a cause, and we can understand this cause only as the effect of a preceding cause etcetera, to end at some primordial cause which by definition cannot be understood, then causality ultimately cannot explain anything. More over time and causality you can find in my UPDATE 2 post above (Feb. 8).

    Regards, Anton

      Dear Anton,

      We can speak about the velocity of the photon with respect to its source and receiver. For example, if the photons were emitted by a star and then hit our detector, then we can speak about the velocity of the photons with respect to the star and detector.

      Since the photon has no mass or charge, it cannot express its presence to the objects with respect to which it is supposed to move: having no mass, it cannot have a position. If it doesn't interact, exist to these objects nor the environment to the photon, then it makes no sense to speak about its velocity as there's nothing with respect to which it moves.

      The photon has ENERGY, and therefore it curves the spacetime, according to GR. Therefore, a beam of photons curve the spacetime and interact gravitationally with the objects with respect to which it is supposed to move. You see during a solar eclipse that the stars along the same line of sight as the Sun are shifted. It is because the light from the star behind the Sun is bent toward the Sun and the Earth.

      Since we assume that the universe evolves as a whole with respect to some clock outside of it, we assume the emission of the photon to (causally) precede its absorption elsewhere, according to that clock.

      1) There is neither matter nor clocks outside of the Universe. 2) You try to introduce the Absolute Time measured by God-like clocks placed outside of the Universe. Remember, the Universe has no Absolute Time, no absolute frame of reference, and no absolute space. All is relative.

      If particle A emits a photon which is absorbed by B, a transmission changing the state of both A and B, then A sees the state of B change at the time it emits the photon, whereas B sees the state of A change as it absorbs the photon.

      ''If particle A emits a photon which is absorbed by B...'' if you describe the EPR paradox then this description is not correct; Also, Quantum teleportation transmits quantum state only but not photons or energy, and this teleportation is not instantaneous. The initial photon is destroyed and then is recreated in the finish place.

      I agree with you in sense that there are some problems with causality in quantum mechanics, in consequence of its inability to provide descriptions of the causes of all actually observed effects.

      Sincerely,

      Constantin

      Dear Dan,

      If I understand your term 'cosmic time' correctly, then black holes are much older than the 14 billion years of light-emitting objects: the heavier, the older they are.

      "Gravity is not the major influence on the universe on the large scale, expansion is."

      As to fairy tales, in my essay (and posts to your forum) I try to show that gravity is responsible for both the contraction of masses, the creation of energy at one scale and the simultaneous creation, the expansion of spacetime between the mass concentrations: they are the two sides of the same coin. In my view (weak) gravity powers or is powered by this expansion so we need no dark energy to explain why that expansion doesn't slow down. It is only the bigbang tale which needs inflation and dark energy to keep standing.

      As to paradigm's, I think that a lot of theories have been built upon some fundamental misconceptions, theories on which have been built more theories, the latter theories granting the former ones a false respectability nobody dares to doubt anymore. So I find it hard to learn and use the lingo of the present paradigm without succumbing to the same errors. If to dispute the present paradigm requires me to learn it, to believe in assumptions which to me are misconceptions, then I cannot from within that paradigm attack it: I can only ignore it or point to the many contradictions it contains. As I've become suspicious about many statements of present physics, I had no other choice but to try to re-invent physics, starting from the assumption that QM and relativity theory describe the engineering principles of a self-creating universe. I find it easier to start afresh, to try a different approach since following the beaten path apparently hasn't led to any useful idea. As far as I'm concerned, string theory and the Higgs boson are useless as the problems they are supposed to solve are based on some fundamental misconceptions. To study, to learn all the intricacies of these theories knowing that they won't solve anything but are part of the problem, to me seems a waste of time.

      Regards, Anton

      Anton,

      "If I understand your term 'cosmic time' correctly, then black holes are much older than the 14 billion years of light-emitting objects: the heavier, the older they are."

      In general I would agree with this statement. There is no method to actually determine the age of a BH. For example, an IMBH could have a recent origin from the merging of two or more less massive BHs or it could be quite old. I would say that most SMBHs are old.

      "As to fairy tales..."

      You should read the third reference from my essay, I think you would really enjoy it. Here a copy of the reference and the link: [3] American Scientist, September-October 2007, Volume 95, Number 5, Modern Cosmology: Science or Folktale?, by Michael J. Disney, http://www.americanscientist.org/issues/pub/2007/9/modern-cosmology-science-or-folktale

      "So I find it hard to learn and use the lingo of the present paradigm without succumbing to the same errors."

      I meant that in response to your statement: "I admit that I haven't understood you essay completely because my knowledge of GR is very limited."

      GR is fundamental. IMO, it has some misinterpretations that have lead to incorrect understanding in cosmology and BH theory. These misinterpretations are what I'm exposing in my theories.

      "I had no other choice but to try to re-invent physics, starting from the assumption that QM and relativity theory describe the engineering principles of a self-creating universe."

      You've done a more than admirable job in presenting an alternative. But, my essay would be more comprehendible with a better understanding of GR. How do you know if your lack of GR knowledge hasn't caused you to omit something from your theory? That's all I was implying.

      Dan

      Dear Constantin,

      As to the eclipse, it is not light which bends around the Sun but spacetime itself which is curved and affects the physical relation between the distant star and the observer. To the photon itself, its path would be perfectly straight if not for the fact that to the photon there is no path, no spacetime distance between the points it is transmitted. If to the photon itself it doesn't interact as it is transmitted, then we cannot insist that it does. Its transmission doesn't consist of three separate, independent events, its emission, its voyage and its (accidental) absorption somewhere else, but is a single event. If A emits a photon which is absorbed by B, a transmission changing the state of both A and B, then A sees the state of B change at the time it emits the photon, whereas B sees the state of A change as it absorbs the photon. Though to us the moment when A sees B change and when B sees A change don't coincide in time, it nevertheless it is a single event taking no time at all. To A its own change doesn't precede that of B, nor sees B change itself before or after it sees A change. Only if we assume that there is a God-Clock, an Absolute Time we can determine in an absolute sense what precedes what, is cause of what, and only then can we interpret the speed of light as a velocity. Without such a clock it is just a property of spacetime, how many meters correspond to how many seconds. In my essay I have repeatedly emphasized that there is no such clock.

      As to a photon curving spacetime: according to GR energy only is a source of gravity if and when it can be assigned a position, like I argued in my essay: the energy of a (massive) particle likewise depends on the definiteness in its position. Since the speed of light can be defined as that 'velocity' at which the position of a particle is completely indefinite so it cannot express its energy in interactions, act upon anything, a photon cannot curve spacetime. Another reason why photons cannot, should not interact, is that for photons to be able to transmit force between two particles, they must be impervious to influences which may affect that force, which is why it has no mass, why it isn't delayed by interactions as goes about its business, why it has the 'speed' of light. We should reserve the term 'velocity' for motions proceeding at v < c, for classical situations where causally applies. Though we can describe the propagation of light as if it has a velocity, we should keep in mind that it is a non-causal QM phenomenon. Spacetime is curved by mass, by the continuous energy exchange by means of which particles express and preserve each other's energy, not by photons. This, by the way, is not to say that we cannot predict where and when we can intercept a photon, that is, make the source produce photons for our detector. We should not think about photons as some kind of bullets buzzing through spacetime, as if the state of the source particles can change before that of the absorbing particles, 'before' according to the God-Clock. Unfortunately causality itself cannot exist without such clock, so if we reject Absolute Time (as we must if we are to practice physics instead of metaphysics), then we should discard causality. Though events certainly are related, we shouldn't waste time on irrelevant questions as to what is cause of what. So to say that ''there are some problems with causality in quantum mechanics'' seems to me a gross understatement. I'm well aware that what I propose is completely different from the present consensus about what photons are, so I can imagine your confusion.

      I do not describe the EPR paradox with the above AB sketch. In an EPR experiment (like those of Anton Zeilinger) which entangles two photons, the light source (the particles to emit the photons) at all times is informed about the direction of the polarisation filter in the detector as it continuously exchanges energy with all particles of the setup. So if the source keeps producing pairs of entangled photons, then any photon with the right polarisation to pass the detector filter and be detected is produced together with a photon with the opposite polarisation. As the information about the detector already is present at the source at the time of the emission, there's no need for signals traveling instantaneously from the detector to the other photon which then is thought to assume the appropriate polarisation. It already is produced at the source with that polarisation, so no info is transmitted faster than light and there's no teleportation of Q states. The idea of teleportation originates in the belief that there is a God Clock, in the outdated, 19th century idea that speed of light is a velocity.

      Brilliant essay! Absolutely the right approach, ..to science as well. Reality is essential, and it's about time we left wonderland. 10 points doesn't say it!

      I've found a door.... It's near where you envisaged it would be, ...it's astonishing, and proves you correct. It's all in my essay, which has masses conceptually in common with yours. You may enjoy the string too, including identifying particular departures from reality at fault (i.e. the real 'body' x,y and z were once attached to!).

      I'm doing very well so far, and consistent with Edwins leading 'Cfield' and Regazas real maths which you should like, also Georgina P (Reality) and others.

      Best of luck

      Sub: Possibility of manipulation in judging criteria - suggestions for improvement.

      Sir,

      We had filed a complaint to FQXi and Scienticfic American regarding Possibility of manipulation in judging criteria and giving some suggestions for improvement. Acopy of our letter is enclosed for your kind information.

      "We are a non-professional and non-academic entrant to the Essay contest "Is Reality Digital or Analog". Our Essay under the same name was published on 29-12-2010. We were associated with Academic Administration as a part of our profession before retirement. From our experience, we were concerned about the problems and directions of current science. One example is the extended run and up-gradation given to LHC, (which was set up to finally prove that Standard Model and SUSY were wrong), even when Tevatron is closing down. Thus, after retirement, we were more focused on foundational works addressing, in one of its many facets, our understanding of the deep or "ultimate" nature of reality.

      Specifically we were concerned about the blind acceptance of the so-called "established theories" due to the rush for immediate and easy recognition even on the face of contradictions raising questions on the very theories. One example is the questions being raised on the current theories of gravitation after the discovery of Pioneer anomaly. While most students know about MOND, they are not aware of the Pioneer anomaly. Most of the finalists of this contest have either not addressed or insufficiently addressed this question. We hold that gravity is a composite force that stabilizes. This way we can not only explain the Pioneer anomaly and the deflection of the Voyager space-craft, but also the Fly-by anomalies.

      Similarly, we were concerned about the blind acceptance of some concepts, such as inertial mass increase, gravitational waves, Higg's boson, strings, extra-dimensions, etc. Some of these are either non-existent or wrongly explained. For example, we have given a different explanation for ten spatial dimensions. Similarly, we have explained the charge interactions differently from the Coulomb's law. We have defined time, space, number and infinity etc., differently and derived all out formulae from fundamental principles. There are much more, which we had discussed under various threads under different Essays. We are the only entrant who defined "reality" and all other technical terms precisely and strictly used this definition throughout our discussion.

      Though our essay was on foundational concepts and we derived everything from fundamental principles, it was basically alternative physics. Moreover, we are not known in scientific circles because we did not publish our work earlier. Hence it is surprising that even we got a community rating of 3.0 and (12 ratings) and Public Rating of 2.5 (2 ratings). We have no complaints in this regard. However, we have serious reservations about the manner in which the finalists were chosen.

      A set of thirty-five finalists (the "Finalists") have been chosen based on the essays with the top Community ratings that have each received at least ten ratings. The FQXi Members and approved Contest entrants rate the essays as "Community evaluators". Since many of the FQXi Members are also approved Contest entrants, this effectively makes the contestant as the judge for selection of the finalists. This process not only goes against the foundational goals of the Contest, but also leaves itself open for manipulation.

      Most contestants are followers of what they call as "mainstream physics". Thus, they will not be open to encourage revolutionary new ideas because it goes against their personal beliefs either fully (like our essay) or partially (like many other essays that did not find place in the final list. One example is Ms Georgina Parry. There are many more.) The prime reason for such behavior is cultural bias and basic selfish instinct of human beings. Thus, truly foundational essays will be left out of the final list.

      In support of the above, we give a few examples. While there are some really deserving contestants like Mr. Julian Barbour, who really deserve placement in the final listing, the same cannot be said for many others. Mr. Daniele Oriti, who tops the list of finalists, says that whether reality is digital or analog "refers, at least implicitly, to the 'ultimate' nature of reality, the fundamental layer." He admits that "I do not know what this could mean, nor I am at ease with thinking in these terms." Then how could he discuss the issue scientifically? Science is not about beliefs or suppositions. His entire essay exhibits his beliefs and suppositions that are far from scientific descriptions. He admits it when he talks about "speculative scenario". Yet, his essay has been rated as number one by the Community.

      The correspondence between us and Mr. Efthimios Harokopos under his Essay and our comments under the various top ranking finalists show the same pattern. One example is Mr. Paul Halpern. We have raised some fundamental questions under the essay of Mr. Hector Zenil. If the answers to these questions are given, most of the finalists will be rejected. If the idea is to find out the answers to these questions, then also most of the finalists will be rejected.

      The public that read and rated the essays are not just laymen, but intelligent persons following the developments of science. Their views cannot be ignored lightly. Mr. Daniele Oriti, who tops the list of finalists as per community rating, occupies 35th place in public rating. Mr, Tejinder Singth, who is 7th among the list of finalists as per community rating, occupies 25th place in public rating. If public rating is so erroneous, it should be abolished.

      Secondly, the author and interested readers (including FQXi Members, other contest entrants, and the general public) are invited to discuss and comment on the essay. Here personal relationship and lobbying plays an important role. An analysis of the correspondence between various contestants will show that there was hectic lobbying for mutual rating. For example: Eckard Blumschein (Finalist Sl. No. 15) had written on Mar. 15, 2011 to Mr. Ian Durham (Finalist Sl. No. 3) "Since you did not yet answered my question you give me an excuse for not yet voting for you." There are many such examples of open lobbying. One of the first entrants visited most contestants and lobbied for reading his essay. Thus, not only he has received the highest number of posts under his Essay, but has emerged as one of top contenders.

      The above statement gets further strengthened if we look at the voting pattern. More than 100 essays were submitted between Feb.1-15. Of these 21 out of 35 are the finalists. Of these the essays of 14 contestants were published in 5 days between Feb. 14-18. Is it a mere coincidence? For some contestants, maximum rating took place on the last day. For example, on the last date alone, Mr. Paul Halpern rose from 14th place to 5th place, Mr. Donatello Dolce rose from 35th place to 14th place, and Mr. Christian Stoica came into the top 35. All these cannot be coincidental.

      Thirdly, no person is allowed to submit more than one essay to the Contest, regardless if he or she is entering individually or as part of a collaborative essay. Yet, we suspect that some have indulged in such activities. For example, we commented below the essay of one contestant on March 4. We got a reply from the next contestant the same day. The correspondence continued. The original contender has not replied to us. In fact he has only replied twice in 20 posts. This is surprising.

      In view of the above, we request you to kindly review your judging process and forward all essays to an independent screening committee (to which no contestant or their relatives will be empanelled), who will reject the essays that are not up to the mark and select the other essays without any strict restriction on numbers to the final judges panel. This will eliminate the problems and possibilities discussed by us. This will also have the benefit of a two tier independent evaluation.

      Our sole motive for writing this letter is to improve the quality of competition. Hence it should be viewed from the same light".

      Regards,

      Basudeba.

      As a last remark, I am surprised that nobody (as far as I know) ever remarked that adding a decimal to the Planck constant and subsequently settimg it equal to 1 in our equations, actually comes down increasing the magnification power of our 'microscope' with a factot 10, so if the Planck length would be an absolute minimum length (which I argue it is not), then with every new decimal we add to it, we decrease this 'minimum' distance.

      If there is no reason why there ever should come an end to the number of decimals we can add to the Planck constant, then there can be no minimum distance.
