Theology, Philosophy, Neurology all suggest a different answer but personally I think this:<BR/>We are looking at observations and experimental data through our own empirically FALSE visions. What we "see" in life is not real. Just consdering visible wavelengths our own perception via our eyes is less than 5% of the Actual wavelengths in reality. We cannot see Ultraviolet or Infrared radiation, nor X Rays or Gamma Rays, Microwaves or Radio Waves (but they are there). If our senses were tuned differently we would experience a VERY different world than we, as human's do. Combine this false empiracalism with the fact that we live in a linear, pattern finding, neuronally logistical world which is patently false on its own, then we can start to realise that by trying to understand the nature of reality from the erroneous and intrinsically deceptive position that being humans puts is in, becomes an existential nightmare.<BR/>*sigh*<BR/>On the plus side, when it's sunny we all feel nice inside.<BR/>*smile*Karl Le Marcshttps://www.blogger.com/profile/01402028443489182100noreply@blogger.comtag:blogger.com,1999:blog-6467236423735891536.post-25577487289406328362008-03-04T09:27:00.000+00:002008-03-04T09:27:00.000+00:00I have swopped a couple of emails with Marcus Chow...I have swopped a couple of emails with Marcus Chown about this very issue. As an occasional reader of this blog Marcus pointed out to me that the positions taken by MWI (no collapse) and Copenhagen (collapse brought about by the act of observation)with regard to the 'wave function' have now been replaced by the concept of 'decoherence'. I have been aware of this word but I have never looked into it in any great detail. As I understand it it is an attempt to explain why we see everyday objects as separate and not blurred together. It uses as its basis Copenhagen but is interested in what happens at the boundary between the observed and the unobserved. It argues that the when a quantum object interacts with the environment this interaction acts as an 'act of observation'. Trillions of these interactive 'observations' smooth out (decohere) the quantum discreetness and 'collapse' it into classical-looking behavior. <BR/>But not all physicists accept this. Brian Greene in his fantastic book "The Fabric of the Cosmos" writes:<BR/>"Even though decoherence suppresses quantum interference and thereby coaxes weird quantum probabilities to be like their familiar classical counterparts, each of the potential outcomes embodied in a wavefunction still vies for realisation."<BR/><BR/>So it looks like the 'measurement problem' may still be with us.Anthony Peakehttps://www.blogger.com/profile/12199138770925114308noreply@blogger.comtag:blogger.com,1999:blog-6467236423735891536.post-17214157921234469452008-03-04T07:31:00.000+00:002008-03-04T07:31:00.000+00:00JOHAR, et al.-- A little reading has generated a s...JOHAR, et al.-- A little reading has generated a smaller, but still finite, amount of understanding. The Copenhagen Interpretation uses the collapse of the wave function to completely eliminate all but a single possibility. Everett's Many-Worlds Interpretation, however, uses decoherance to allow the observer to ignore all the other possibilities -- that is, it only LOOKS LIKE the wave function has collapsed. In the MWI, all possible states still exist but only one is observed and this is not due to the act of observation. It is due to a "leaking" into the environment (which I don't totally understand).<BR/><BR/>This splitting can account for "random" events and for "lucky streaks." If a card is balanced on edge and allowed to fall, it will fall either face up or face down. One such event will produce two worlds; in one world, decoherence produces an observable result that it fell face up and in another the observable result is that it fell face down. Repeat the event and now there are four worlds: Up-Up, Up-Down, Down-Up, Down-Down. "You" will "be" in one of those four worlds. Repeat again and again and you will find that most worlds will have a 50-50 chance of each event. BUT, one world will see ALL the cards face up and one world will see ALL the cards face down. If "you" happen to be in one of those worlds and you placed the right bet, you are VERY rich.kenhttps://www.blogger.com/profile/08372377464212144183noreply@blogger.comtag:blogger.com,1999:blog-6467236423735891536.post-58512023877423745492008-03-03T19:27:00.000+00:002008-03-03T19:27:00.000+00:00... an infinitesimal change in the way you collaps...<I>... an infinitesimal change in the way you collapse your wave function ...</I><BR/><BR/>Is it possible to "force" the result of the wave function collapse?

MWI says that every possibility exists but aren't they still existing as a probability and doesn't each one need a conscious mind to collapse to a particular world? But it also seems that there is a chicken-n-egg think going on. Each of the many worlds don't exist until the collapse but the each world would have to exist for there to be a consciousness to affect the collapse.kenhttps://www.blogger.com/profile/08372377464212144183noreply@blogger.comtag:blogger.com,1999:blog-6467236423735891536.post-7943097160713566842008-03-01T13:44:00.000+00:002008-03-01T13:44:00.000+00:00Hi Guys.

In MWI why isn't consciousness required if the particles are in every possible timeline? Surely a conscious observer is required to collapse the waveform? Why doesn't the probability wave need to collapse in MWI?

Philosophy and the Meaning of Life" and "Do You Think What You Think You Think?" Also, as a writer and a follower of politics and current affairs his "Making Sense: Philosophy Behind The Headlines" is useful to have in your mind. And not by Baggini but in a similar style of writing another thought-provoking book of little snippets of philosophy etc is "Paradoxes from A-Z" by Michael Clark - worth reading even if only interested in the Zeno Bisection Paradox, Thompson's Lamp and Cantor's infinities about which Tony discusses in his theory.Karl Le Marcshttps://www.blogger.com/profile/01402028443489182100noreply@blogger.comtag:blogger.com,1999:blog-6467236423735891536.post-76347653058744417522008-02-28T16:20:00.000+00:002008-02-28T16:20:00.000+00:00Thank you sir.Will definately check that out as so...Thank you sir.<BR/><BR/>Will definately check that out as soon as i finish:<BR/><BR/>"The pig that wants to be eaten" and 99 other thought experiments.<BR/><BR/>Don't laugh - it's bloody good.Hurlyburlyhttps://www.blogger.com/profile/14991008325876909831noreply@blogger.comtag:blogger.com,1999:blog-6467236423735891536.post-7130291016218022442008-02-28T15:38:00.000+00:002008-02-28T15:38:00.000+00:00And Hurly, if you liked Chown's "The Universe Next...And Hurly, if you liked Chown's "The Universe Next Door" then check out Michio Kaku's "Parallel World: The Science of Alternate Universes and Our Future in the Cosmos".

I had read Christian's short papers, "Fundamental Intersubjectivity" and "Consciousness and Quantum Holography" and think it is very important that he places emphasis on the supremacy of meaning over mechanism, as did William James.

That being how this theory effects those that die of illness and at early ages. Indeed, your theory like most others seems to attract a certain dynamic of people, that being individual thinkers that are able to appreciate what is being posed. I then asked you about what you also then phrased as the problem of "other minds" and your answer given was also very similar. <BR/><BR/>I hope you don't mind me posting your reply please feel free to remove it if you do:<BR/><BR/>Remember that each universe is an observer-created universe (if one applies the Copenhagen Interpretation and Everett's Many Worlds). As such 'we' observe what happens in our universe. The versions of people we observe similarly exist only in our universe not in their own. For example if you read Marcus Chown's book The Universe Next Door he is quite specific that we never die in our own universe but others see us die in theirs. The same applies for people who are observed to die young by us. In their universe they, also, never die.<BR/> <BR/>You are quite right in picking up this moralistic weakness in my theory. However if observed reality is as it seems then these poor individuals only had one chance at life and they died (or were born retarded, or crippled) which is just as ethically horrible.<BR/> <BR/>Of course I have no idea that my interpretation is right (and after all, my theory can be accused of being extremely solipsist) but I still think it works better, and is much fairer, than what we observe to be the true nature of reality.<BR/><BR/>Great post.Hurlyburlyhttps://www.blogger.com/profile/14991008325876909831noreply@blogger.com
