  • Physicists investigate the structure of time, with implications for quantum mechanics and philosophy
    worth communicating with When you make a stupid statement and somebody points it out you throw your toys out of your pram For example I quote your post There is a phase delay due to gravity which increases inversely with distance If it increases with distance the further away from a mass you go the more it affects you This is patently nonsense javjav 3 7 5 6 Feb 04 2016 I quote your post There is a phase delay due to gravity which increases inversely with distance If it increases with distance the further away from a mass you go the more it affects you This is patently nonsense RegMundy do you understand the difference between inversely with distance what he said and with distance what you get I suggest you change your username ask that guy of the aether stuff how to do it he does everyday and try a more humble approach from there Writing insults you don t learn for doing it you have to read In that way you may learn something rather than wasting others time I can tell you that it works I have learned several things from those guys you are criticising And if you don t understand something you can simply ask about it many of the people here don t mind to help others But by now just read Mike Massen 2 5 8 Feb 04 2016 Reg Mundy confused problems with it Do you understand basic optics Facile inappropriate NOT an issue of comparative optics a space time effect as described in Einstein s field equations can be approximated by Pythagoras with Newton s gravitational G formula Reg Mundy says photons passing near the center deviate slightly and photons passing further out from the centre deviate MORE This is WHY you can t approach G lensing in same way as optics under your odd methodology One is refraction at sharp density transitions other is gradual deflection across a G field of influence if you like only appear similar hence metaphor but that s primarily the simplistic description for those not in Physics Reg Mundy says light is scattered and DOES NOT FORM AN IMAGE No any scattering is due to combinations of collisions absorption re emission with light in a G field re point sources plainly none of that occurs ie metaphor DoctorAlex 1 6 5 7 Feb 04 2016 I think that the paper of M Faizal clearly demonstrates few tendencies One is a general problem of decreasing of journal referees quality It is surprising that such an obviously fake paper passed through serious referee Another tendency is a growing community of science fiction physicists who are badly educated in basics of physics It seems that M Faizal has never heard of Lorentz invariance QED and their place in explaining things When it turns out that al these science fiction ideas are simply school level mistakes the serious reseaches and their attempts to find new physics are also seriously compromised I believe that publication of M Faizal paper in a serious journal and publicity it has got via popular cites is a shame and is a sign of serious problems with estimation of quality of scientific research even on basic level Noumenon 1 7 5 6 Feb 04 2016 The word mind is undefinable It means nothing It is quite literally the most manifest phenomena observable All observable phenomena are investigable in principal It can be defined as the cognitive faculties that enables consciousness perception thinking judgement and memory These a priori cognitive faculties determine the form of experience as explained above The word mind is undefinable It means nothing That sounds rather definitive Yet philosophical He also denies that consciousness exists He agrees with a philosopher about this D Dennett despite proclaiming that philosophy is invalid generally btw Dennett does not refute that consciousness is a phenomenon in fact he attempts to explain that phenomenon via processes of the brain He performs experiments on himself but only while he is sleeping TheGhostofOtto1923 4 5 5 8 Feb 04 2016 It is quite literally the most manifest phenomena sic observable Nou goes on to quote from wiki https en wikipe iki Mind So let s pull a few more quotes from nou s source A lengthy tradition of inquiries in philosophy religion psychology and cognitive science has sought to develop an understanding of what a mind is and what its distinguishing properties are Huh This doesn t seem very manifest to me whatever not means by manifest What else the mind body problem which considers whether mind is somehow separate from physical existence Well that s easy It s not dualism and idealism or the mind is identical with the brain or some activity of the brain Note the subtle interjection of ism words as if they are actually meant to clarify the question They dont So nou says that the mind is a well defined something or other and then quotes an article which definitively says it is not Cont TheGhostofOtto1923 4 5 5 8 Feb 04 2016 It s a sure bet that we can ask any philo religionist psychologist or cognitive scientist what this mind thing is and they will all give you wildly conflicting answers Of them all only the scientist has a chance of producing falsifiable answers because All observable phenomena are investigable in principal and only he has the proper tools and training to do so And while the scientist may use the word mind from time to time he is invariably thinking brain Nou and his mystic heros prefer concepts like mind and consciousness because they invariably include an element of that which can never be defined or meta physicality a realm through which he and his buds can forever roam without risk of capture and containment This is no accident metaphysics was invented to replace the soul concept They both exploit our animalistic terror of the cage and of death But obviously this is exactly why these words are undefinable and thus unscientific Noumenon 1 7 5 6 Feb 04 2016 There you go again making false accusatory presumptions wrt what I think or know I m an atheist and don t believe in anything mystical My posts serve to reject metaphysics in science not promote it I stated plainly enough above that the mind is an emergent phenomenon from a physical brain so have never stated that the mind is somehow separate from physical existence The opposite in fact You invent strawman arguments as you go along and deliberately misrepresent others opinion despite that they have stated the exact opposite in this very thread Dishonesty TheGhostofOtto1923 4 5 5 8 Feb 04 2016 He agrees with a philo about this Daniel Clement Dennett III born March 28 1942 1 2 is an American philosopher writer and cognitive scientist whose research centers on the philosophy of mind philosophy of science and philosophy of biology particularly as those fields related to evolutionary biology and cognitive science Dennett is a scientist He has written many books and papers on the subjects of mind and consciousness trying to bridge the chasm between philosophy In one of his latest presentations a TED talk entitled consciousness is an illusion https www ted c guage en he seems to have abandoned the philo side entirely He gives many examples of how flawed our brains are and how easily they are fooled and then suggests that these flaws are what give rise to the illusion of consciousness He concludes like the scientist he is by saying that more and better theories are needed TheGhostofOtto1923 4 5 5 8 Feb 04 2016 I m an atheist and don t believe in anything mystical My posts serve to reject metaphysics in science You are a slave to your hobby You say you reject the unphysical but you do so using words which clearly reference it And you quote philos and scientists who are clearly mystics when discussing your favorite subjects Metaphysician know thyself Simply declaring that you are not something doesnt make it so I detect a significant cognitive disconnect Better see a meta doctor Noumenon 1 6 5 7 Feb 04 2016 only the scientist has a chance of producing falsifiable answers because All observable phenomena are investigable in principal and only he has the proper tools and training to do so You re the only one here trying to falsify a meaning for mind and consciousness As I said How the mind works will not be discovered by A I dorks i e It will require many disciplines from neuroscience cognitive science psychology physics epistemology philosophy It is quite literally the most manifest phenomena plural form of phenomenon so correct observable Just because little is known about the phenomenon of consciousness does not invalidate the attempt at understanding If it did science would not exist Noumenon 1 6 5 7 Feb 04 2016 You say you reject the unphysical but you do so using words which clearly reference it Patently false I use words that you personally don t understand or deliberately misrepresent without bothering to ask for clarification And you quote philos and scientists who are clearly mystics when discussing your favorite subjects You have called Roger Penrose Eugene Wigner d Espagnat etc mystics and therefore you have no credibility as I reference mostly physicists and physicists who are philosophers of physics who reflect on what theory means I reference Kant and Hume but never any metaphysical aspects of their ideas In fact Kant rejects metaphysics as a possible source for knowledge You have been told this but your dishonesty prevents you from learning anything new You should be taking notes as I post but instead behave as a troll TheGhostofOtto1923 4 5 5 8 Feb 04 2016 I mean look at this The what is the mind problem should be studied in physics the what is the brain is for biologists You ve heard of biophysics Biology IS physics Brain function is governed exclusively by physical laws By saying that the mind and physics are something which exists beyond biology is a way of saying that it contains non physical or extra physical elements Do you not see it Physics biology brain Using the word mind implies there is something extra there This leaves you free to postulate that only a mystical phenomenon such as consciousness can collapse the waveform And as ayn rand said you can decide a priori that humans are too imperfect and flawed and unworthy of experiencing the entirety of something You need to be a god to grok the noumenon Noumenon 1 6 5 7 Feb 04 2016 The what is the mind problem should be studied in physics the what is the brain is for biologists You need to be a god to grok the noumenon I did not make that post not that facts are important to you Phys1 3 7 5 3 Feb 04 2016 In one of his latest presentations a TED talk entitled consciousness is an illusion This sounds like the dead end that strict positivism leads to How is consciousness an illusion If I would be unconscious my wife would call an ambulance right away Biology IS physics I disagree For example there are no proteins in physics They have physical properties but they also have chemical biochemical and biological properties TheGhostofOtto1923 4 6 5 9 Feb 04 2016 Patently false I use words that you personally don t understand or deliberately misrepresent I looked them up for I quoted from your own reference I ve shown you that experts say they are impossible to define bothering to ask for clarification Like I say I can ask 10 philos or 10 priests and get 20 entirely different answers And thear credentials would all be better than yours you called Penrose et al mystics AGAIN I didn t decide that I ve referenced many experts which use that term to describe facets of their work The facets you yourself use to justify your own extrasensory proclivities kant and hume Kant preferred faith to evidence He was a defender of the church And hume was a racist Perhaps his penchant for prejudice was what gave him the notion that he could discern the nature of the universe just by sitting and thinking about it TheGhostofOtto1923 4 5 5 8 Feb 04 2016 I disagree For example there are no proteins in physics They have physical properties but they also have chemical biochemical and biological properties What a strange thing to say Proteins are chemistry Chemistry is governed by physical laws Physical laws are physics Correct This sounds like the dead end that strict positivism leads to I see you are also an ism lover Explains a lot TheGhostofOtto1923 5 5 7 Feb 04 2016 I did not make that post not that facts are important to you You mean today don t you I m referring to the discussion we had some time ago re ayn rands hatred of kant She described how kants ideas demeaned human potential in exactly the same way the church did You began to mutter about how you agreed with rands politics even though you loved kant too etc Remember Noumenon 2 5 8 Feb 04 2016 So what is your point I did not make the post that you quoted today nor at any time Do you have a coherent point of objection to something that was stated by me here You insist that philosophers are vague and yet at the same time you can t help but to disparage thinkers with accusations like Kant Hume Penrose Wigner d Espagnat Pauli on account of some off topic irrelevancy Hume is a racist so this means what his analysis of causality is invalid Penrose believes in Platonic mathematical idealism so this means that he is not a preeminent physicists B d Espagnat won the Templemen prize and may be a theist so this means that his distinguished work in physics is now invalid Do you see how your arguments are all over the place like a troll It s hard to have a coherent discussion with you because you argue by proxy accusations and with ad hominems Noumenon 1 6 5 7 Feb 04 2016 I agree with Rand s political ideology but not with her objectivism nor with her misinformed opinion of Kant I agree with Kant s transcendental deduction and implications for knowledge his rejection of metaphysics as a source for knowledge his noumenon phenomenal distinction and his a priori synthetic analytic distinction but not his theism The fact is you re are just tossing things you found via internet proxy against the wall to see what sticks I expect you to explain what it is I stated that you object to and why I am capable of learning new things but not by being attacked in a vague way Listing other people who don t agree with Kant Hume etc is not itself a counter argument as I can also list people who do WHY Noumenon 1 6 5 7 Feb 04 2016 In one of his latest presentations a TED talk entitled consciousness is an illusion This sounds like the dead end that strict positivism leads to How is consciousness an illusion Obviously we lose consciousness when we sleep and is equated with self awareness so it IS an investigable phenomenon and it would be patently absurd to deny that much They probably only mean that the notion that consciousness is like akin to the soul as a separate thing apart from the working of the physical brain is an illusion To this I would agree However this does not mean that it is not an actual phenomenon emergent from a physical basis Noumenon 1 6 5 7 Feb 04 2016 Noumenon I am not a positivist but I think without a lead you can not advance beyond the ensemble interpretation because the odds are against you Singles systems are not deterministic though I meant to add Einstein originally proposed the ensemble interpretation of the probabilistic element in QM not out of practical utility but because he denied indeterminism and appears to have desired to obscure the intrinsic probabilistic nature of quantum phenomenon in the statistics of ensembles Given your reference though Ballentine shows that it is a useful interpretation so you re certainly not wrong TheGhostofOtto1923 5 5 7 Feb 04 2016 ou insist that philosophers are vague and yet at the same time you can t help but to disparage thinkers with accusations like Kant Hume Penrose Wigner d Espagnat Pauli on account of some off topic irrelevancy They are not off topic Trying to discuss science using indefinable and esoteric philo terms is off topic It s little different from the god lovers who come here and try to do the same thing Philo arguments are unassailable like trying to climb a whipped cream mountain A sugarless whipped cream mountain And so one is left with attacking the structure of the arguments themselves the source of their hopeless ambiguity and by extension the entire discipline Hume was a racist He must have had in his mind a philo rationalization for that sort of prejudgment In retrospect we can see that there is no logical explanation for that sort of thinking and so we can suspect that the rest of his philosophy was similarly tainted Protoplasmix 5 5 2 Feb 04 2016 Biology IS physics I disagree For example there are no proteins in physics They have physical properties but they also have chemical biochemical and biological properties I disdisagree Please see Introduction to protein folding for physicists Everything is physics Even nothing is physics TheGhostofOtto1923 5 5 7 Feb 04 2016 Evidence tells us that there is no basis for racism except our penchant for tribalism Others in humes time rejected it but he did not Obviously he reached that conclusion in the framework of his particular theories of logic which were not based on evidence but on cultural tradition The idea that one could discern the nature of the universe via deep thought or prayer or whatever rather than a painstaking analysis of evidence is also a bankrupt cultural predisposition And the discipline of philosophy is established and thrives on exactly that predisposition Plato formalized that notion thereby legitimizing religion and philosophy Aristotle emphasized evidence and causality and gave us science They both knew that humans would never surrender the former and so gave it an intellectual basis on par with the latter so that it could be tailored to serve They fooled most of the people most of the time But I doubt they intended this farce to endure TheGhostofOtto1923 5 5 7 Feb 04 2016 Obviously we lose consciousness when we sleep and is equated with self awareness so it IS an investigable phenomenon Jesus You don t even know what consciousness is supposed to be Sleep is just one of many types of consciousness we experience and sleep itself comprises several states of consciousness TheGhostofOtto1923 5 5 5 Feb 04 2016 even nothing is physics Which is what krauss tried to tell albert the philo who apparently had no idea what he was talking about Krauss responded in an interview published in The Atlantic calling Albert moronic and dismissing the philosophy of science as worthless Hear hear TheGhostofOtto1923 5 5 7 Feb 04 2016 I agree with Rand s political ideology but not with her objectivism nor with her misinformed opinion of Kant Misinformed Ayn rand Right And just who would have informed her correctly You and your crack team of kantians who obviously have the only true and right ism that ever was Or perhaps you re a neo in which case you could meet with a bunch of neo randites and set them straight mano a mano I understand this sort if dialectic can get rather messy What a joke javjav 1 5 4 Feb 04 2016 what is the brain is for biologists You ve heard of biophysics Ghotto I agree with most of your opinions But the way you manipulate my post is wrong I said Biologists to abbreviate the details you mention are true but totally unnecessary for my explanation By saying that the mind and physics are something which exists beyond biology is a way of saying that it contains non physical or extra physical elements I said the opposite I said that mind study belong to physics You also obviated the experiment I described which illustrates what I say I proposed to study consciousness strictly as a physical phenomena but you try to make it look the opposite If we can make it artificially which is not known then we can separate mind from biology to study it better also checking for QM implications It is not utopic first stages are already in place the BlueBrain project being an example https en wikipe Project javjav 1 5 4 Feb 04 2016 The same goes for the experiment that I said I had to condense it in few lines but the idea is perfectly understandable Obviously these experiments will need to simplify a lot of aspects but nothing indicates that you need a complete human brain for consciousness to emerge Just a basic model could work I don t want to go into discussions how simple needs to be an animal to have some demonstrable consciousness but if consciousness is a pure physical phenomena and I agree with you on this it must be obtainable without the need for naturally born creatures and that will give us a much better tool to make a phisycs model to describe what it is to understand it and to develop powerful technologies javjav 1 5 4 Feb 04 2016 For better understanding please read Natural Biology wherever I said Biology There is going to be a point that we will need to differentiate between naturally occurring live from artificially induced and all this is about it Phys1 3 5 2 Feb 04 2016 What s in the newspapers today is also governed by physics What is an ism lover It sounds derogatory Reg Mundy 5 5 6 Feb 04 2016 RegMundy do you understand the difference between inversely with distance what he said and with distance what you get I suggest you change your username ask that guy of the aether stuff how to do it he does everyday and try a more humble approach from there Writing insults you don t learn for doing it you have to read In that way you may learn something rather than wasting others time I can tell you that it works I have learned several things from those guys you are criticising And if you don t understand something you can simply ask about it many of the people here don t mind to help others But by now just read Do you know the difference between increase what he said and no increase Anyway the model for GL is fundamentally flawed So why don t you just read Reg Mundy 5 5 6 Feb 04 2016 MM Reg Mundy says photons passing near the center deviate slightly and photons passing further out from the centre deviate MORE This is WHY you can t approach G lensing in same way as optics under your odd methodology One is refraction at sharp density transitions other is gradual deflection across a G field of influence if you like only appear similar hence metaphor but that s primarily the simplistic description for those not in Physics Reg Mundy says light is scattered and DOES NOT FORM AN IMAGE No any scattering is due to combinations of collisions absorption re emission with light in a G field re point sources plainly none of that occurs ie metaphor I see your intellect is not improving with the passage of time Scattering due to collisions etc is NOTHING to do with this exchange another of your red herrings No matter how you cut it light must be bent more further from the centre of mass thus the model is incorrect Mike Massen 1 5 6 Feb 04 2016 Reg Mundy says I see your intellect is not improving with the passage of time Scattering due to collisions etc is NOTHING to do with this exchange another of your red herrings Feeble personal attacks again a genuine credible graduate of Pure Maths would NOT write like this not refuse Math Reg Mundy claims No matter how you cut it light must be bent more further from the centre of mass thus the model is incorrect Why must it please articulate clearly Gravitational field drops as inverse square we are NOT talking optics at all ie you cannot should NOT apply optics in any respect of refraction here can t you see that P PLEASE Note Fact that evidence confirms this Eg earliest observation by Eddington others refutes your urging it must ie it just Doesnt Why do think please What does that tell us about your

personal attack where Reg Mundy says I see your intellect is not improving You fail as fair policeman re Reg Mundy as his is attack claim yet I only ask Question Had you any presence of mind to

2016 A s number is just the number of nucleons in a gram so its value is conventional A s number is certainly related to standard atomic weight and the atomic mass unit But note that it also works with charge because charge also seems to interact in discrete form the total charge of 1 mole of electrons divided by the charge of a single electron equals A s number How many grams would be a mole of spacetime How many ncleons does it contain According to this paper the discrete interval of time similarly to that of space as worked out by others depends on the amount of energy in it From general relativity we know the geometry of spacetime certainly depends on the energy in it Regardless a mole of spacetime would have 6 02 x 10 23 individual discrete intervals right mole is short for

thanks for the meal but why the exercise My first post stated 2 valid questions which have not been answered The way i see it if time is quantized the spooky action at a distance can t be instantaneous since that would violate this statement So which one is right Second in my view you can t prove something if you don t have the means to verify it Math might indicate the truth but without verification it will remain a theory promile 3 9 5 11 Feb 05 2016 if time is quantized the spooky action at a distance can t be instantaneous since that would violate this statement Such a result could be also explained with limited speed of force mediating the entanglement or not Ryan1981 1 8 5 11 Feb 05 2016 Promile I do not understand what you mean with limited speed of force or how this is related to entanglement When I look up the entanglement effect I am referring to on wikipedia I get According to the formalism of quantum theory the effect of measurement happens instantly This means to me that an infinitely short amount of time has passed giving me the impression that time is continuous Maybe there is such a thing as a response in t 0 after which the next step in time would be whatever lenght of time the minimum time size possible would be Phys1 3 7 5 3 Feb 05 2016 Do not feed the following trolls Benni plasmasrevenge cantdrive45 liquidspacetime gkam kaiserderden

unnecessary for my explanation You tried to justify the term mind by somehow tying it with physics Science has no need for indefinable words whatever the branch BTW I thought phys said this Are you or he a sockpuppet consciousness is a pure physical phenomena and I agree with you on this I didn t say this I said the word is undefinable and the phenomenon however manifested is an illusion We are way

beholdest thou the mote that is in thy brother s eye but considerest not the beam that is in thine own eye Oh Dear Oh Dear You PROMISED to ignore me but here you go again Your promises are about as good as your logic neither are worth a light or beam if you prefer it Now PLEASE either put me on your ignore list or reply to my perfectly logical arguments with LOGICAL arguments of your own Protoplasmix not rated yet Feb 05 2016 mole is short for grammolecule a contraction of two words each of which has no meaning in relation to spacetime Tell me where you think the number comes from Not the constant which has units of mol 1 but the number which is dimensionless Phys1 3 7 5 3 Feb 05 2016 Protoplasmix I assume you mean Avogadro s number It is the number of nucleons that goes into a gram of matter where the weight of a nucleon is set to 1 12th of a 12C nucleus At least that was I was taught in high school It is not a fundamental constant of nature such as the fine structure constant For an update since my highschool days see https en wikipe constant viko mx not rated yet Feb 06 2016 The time have no structure unlike the vacuum of cosmic space This is one of absolutes which serve as absolute reference point for the speed of different physical interactions Professional science does not give a true contribution to human knowledge As lawyers do not give a real contribution to justice They must eat and do carrier Whydening Gyre 5 5 8 Feb 06 2016 As lawyers do not give a real contribution to justice At LAST You ve said something I agree with Noumenon 1 7 5 6 Feb 06 2016 Otto I m still not understanding your point here No one here is saying consciousness or mind are things unto themselves like soul Science makes use of place holder terms all the time These terms are meant only to stand for observable phenomena with the implication being that that phenomenon can in principal be described by physical or emergent laws Here is Newton on the term gravity I have not yet been able to discover the cause of these properties of gravity from phenomena and I feign no hypotheses Newton Because Newton did not understand what gravity IS does not mean he couldn t formulate scientific theory of its observable effects nor did it mean gravity as a phenomenon was an illusion Phys1 3 7 5 6 Feb 06 2016 Ghotto I agree with most of your opinions But the way you manipulate my post is wrong I said Biologists to abbreviate the details you mention are true but totally unnecessary for my explanation You tried to justify the term mind by somehow tying it with

didn t say this I said the word is undefinable and the phenomenon however manifested is an illusion We are way too complex for our own good Some of our delusions are ubiquitous This by doesn t make them real I could argue that electrons are an illusion too and they are not Again without my consciousness I would be hospitalised So consciousness is real Noumenon 1 6 5 7 Feb 06 2016 so consciousness and mind are not illusions As Phenomena They are illusions only to the extent that they are Emergent phenomena from more fundamental laws I was careful to use the word emergent above Is colour an illusion Colour actually does not exist in objects Colour only exists in your mind It exists no where else in reality Your mind Produces the experience of colour upon sensing various frequencies of EM but there is no physical colour in that fundamental force of nature except only by definition In this sense you could say colour is an illusion because it is emergent from physical laws but in itself does not exist as an independent reality yet at the same time the experience of colour
