Discussing Reality

This group will be to discuss books that deal with different aspects of reality, mainly from the viewpoint of science, but with overlap into history,philosophy and spirituality. The Category structure here doesn't really have a single place for a group like this. One of the things to explore is consensus reality - the view of the universe we...more »

    Should objective reality be measureable?

    I have recently started reading the book "New Empror's Mind" by Roger Penrose. Among too many other interesting things, one important yet old question has attracted my attention. As far as physical theories are concerned, scientists have always made use of the implicit assumption that there should be no non-detectable elements in their theories of the world. In this they have taken for granted a positivistic point of view. Yet with the advent of Quantum Theory there seems to have emerged an exception to this a priori conjecture. The state function in Quantum Mechanics is something which is attributed to a system yet it is generally something unmeasureable. On the other hand there are very good reasons to support the idea that state function is a fundamental element of reality even more than that of space and time. There remains this important question. Should every element of objective reality be measurable? or should measurability be a physical property of the elements of the physical universe?

    Just to get this started, I do not believe it should be measurable. At least not for us. There are certain things which can be measured from within but many others that cannot. (when you look at the world around us)
    It might be hard to use a measuring cup to measure milk from inside the cup and difficult to measure a sock from inside. Some things you can approximate but many others just cannot be measured from within the things you are trying to measure so why would objective reality be completely measurable from within it? Also another question comes to mind in relation; why would we want to measure everything anyway?

      You have in fact brilliantly stated the same problem in other words: is there anything outside our measurable world? I believe that what I am inquiring about measurability is directly related to this question. However what I can’t conjecture about is the existence of this hypothetical world though it seems that its existence is increasingly necessary to have a unified picture of our physical world or who knows? Maybe we are lacking the sensations necessary to recognize the effect of this world at the moment and being equipped some day with these senses we become capable of its recognition.
      Concerning your question of the necessity of measurement and measurability I believe that science and logical thinking is one of the greatest achievements of human being in understanding nature and measurements have formed the backbone of this attitude. I believe that science is the most valuable tool we have at our hand to learn about nature and it’s worth insisting on its bases as far as possible.

      There is no gainsaying the fact that Science and its rigours are and will continue to be the most valuable tool in our attempt to understand reality. However, with the advent of Quantum physics, the boundary line between within and without is increasingly getting blurred. The process of measurement, as Classical Science looked at it, can no longer claim to be a totally objective measurement. The very act of observation that goes into a measurement has some significant impact on the measurement.
      I think the better way to look at this would be to change the paradigm from which conventional Science operates. I think the paradigm of matter-begets-consciousness should change to Consciousness-begets-matter. I.e instead of treating Consciousness as an epiphenomenon of matter, it should be the other way round.This change in paradigm will help us answer a lot of paradoxes. Amit Goswami's book Self Aware Universe deals with this issue in a beautiful way.

    I have obviously come to this discussion rather late, but I will throw in my two cents as a way of introducing myself to the group:

    Firstly, the question at hand assumes (if I am not mistaken) that there can *be* such a thing as Objective Reality. Okay. I accept that as a premise for the discussion.

    Secondly, there seems to me to be another layer to this. Measurability is more than positivistic. Positivism is often referred to as restricting oneself to using only the physical senses; to discard spiritualism, new age stuff, etc.
    But a core precept of science, this measurability as you point out, is taking it out of the realm of human perception and into the realm *consensus*.

    Measurability after all, presupposes that a physical thing, an effect, a phenomenon, can be sought out/reproduced at will and will measure the same every time. The premise of an Objective Reality is also a premise of Consensus Reality. The supposition that if an Objective Reality exist it *must* and *will* behave the same way for everyone, everytime. I may see or hear something, even measure it or record it, but if everyone else can't find it, or do it, or come up with the same measurement - my measurement is discarded as invalid.

    Many spiritual traditions subscribe to the precept that truths should not be revealed to a student until they ask the teacher directly about the subject. In this way, the student is never confronted with a concept they are not psychologically ready for.
    Science, interestingly, seems to operate in a similar way. You cannot build a device to detect gravity (let alone measure it) until the day it occurs to you that such a thing might exist. You then must contemplate the incidental evidences around you to hypothesize *how* it might work, then try creating something to measure it. The student must think of the subject, and ask the question before the wisdom is revealed. The "teacher" (the material universe in this analogy) volunteers nothing.
    My point is, that if we do insist that our ability to measure a thing is the defining parametre of whether that thing exists, we must remember we have only measured that which it has occurred to us to measure. If something is undetectable and unmeasurable by any device.. like... I don't know.. ghosts, for example.. is that because they don't exist, or that we have never framed the question sufficiently well to have made the correct device to measure them?
    Likewise, *must* an Object Reality be a Consensus Reality? We operate on the assumption that an Object Reality would operate that way because that has been our experience... but has it been? If you throw away every incident of observed, measured experience that could not be reproduced, then you accept as real only that which can be reproduced on demand - you engineer your own definition ... it is a self-fulfilling definition.

    Well, these are my musings on the subject. I do not subscribe to the concept of Object Reality, so it is largely an intellectual exercise to me. Have you read The Holographic Universe by Michael Talbot?
    Very cool.

      A T, interesting thoughts.as you say there can be alot or 'reality' out there that is not measured as we have not noticed/observed it yet.but when you say that you dont subscribe to the concept of objective reality,how do you subscribe to possibility of our mutual communication here?

      Hello, ammar!
      I want to qualify my statements by saying that I try and view ALL beliefs as no more than that: beliefs. I don't think the human mind is capable of comprehending the vastness of Creation, so we glean what knowledge we can and from that we create a workable visualization of the nature of things.
      We all try and make our visualization as near to our perception of reality as we can make it, but we must never, ever forget it is merely that: a visualization.
      That said, I think all of us who are experiencing the physical world are creating, molecule by molecule based on our expectations and preconceptions. What little I know of Quantum Physics seem to harmonize well with this aspect of my belief. When we are observing and experiencing something, it exists in physical space, when we are not - it ceases to be a physical thing. When we return to it, expecting it to be there - it is - as we expected, BECAUSE we expected.

      Hi A T!:) that the Creation as you say is vast and perhaps way beyond conceptualization of human mind,is what i agree with.With regard to your comment on creating reality through our observation/expectation,i agree that QT is the most established theory of our times,despite voices of dissatisfaction emerging against it in scientific community.But does QT deny 'objective reality'?If it were so QT wouldnot be a science with power to predict phenomena that are of common observation for us all.
      Why do we all choose to observe similar/same things out there and are able to agree on validity of certain theories based on observation etc.?
      One explanation ofcourse is that because there is an objective reality out there in the sense of being independent of human observation.But many interpretations of QT do throw that into doubt.The other could be that we are all biologically and culturally constructed in similar ways and hence expect and observe and therefore create same reality and are thus able to communicate with each other?In other words while the world observed by us may not exist objectively for observers other than humans.All humans nevertheless are all programmed(so to speak) to observe/expect more or less similar phenomena or similar 'reality'.For me that set of common,similar phenomena we are bound to observe constitute an 'objective reality' for us humans.That objective human reality,so to say, makes communication possible between us and also limits the possibility of potential experiences that we can have to a finite range.If there were no such well-defined 'objective reality' for us all then i could go out in front of a hurtling bus and by tuning my mind to expect no injury,have no injuries;by expecting no death be immortal etc.I know many would say we could indeed do all that!:)

      Yes, ammar - I have to say I am one of those who would say, "yes, you can do that!" What all of the great spiritual and religious figures of history - Buddha, Jesus, etc - have repeated is: *All people can do what we have demonstrated. It is within you. You don't have to learn how - you have to realize.*
      What ensures that we are hit by the bus and injured - is that in our hearts of hearts - really - it is what we are *certain* will *inevitably* happen.
      So it does.
      Others also are influencing the physical realm - the driver - the witnesses. What we have to understand (again, IMHO) is that we do not have the *potential* to create physical reality from our expectations and perceptions, *we are already doing it*. We're just not doing it consciously with any intent or direction.
      I must also say, for the purposes of this discussion, I consider the term Objective or Object Reality to mean a physical reality utterly independent of us - that existed before any sentience and would continue after all sentience was gone. Many (especially in philosophical circles) would consider no physical reality Objective because we are affecting every experiment we arrange *by arranging it* and by influencing it by the physical presence of light (so photographs can be taken), body odour, our respiration in the room, etc - but that is NOT what I am talking about. If I believed that was the only ways humans affected things - through physical presence and bodily presence - then I would believe in Objective Reality. However I believe our wishes, intentions and expectations mold the physical universe at a sub-atomic level.

      A T: "we do not have the *potential* to create physical reality from our expectations and perceptions, *we are already doing it*. We're just not doing it consciously with any intent or direction." How do we do it consciously?I have just been consiously trying to bend the metal spoon in my hand by thinking i could do so,but cant.what does doing it 'consciously' really mean?!:)

      He, he! The spoon thing's not working for you either, eh? LOL!!

      Truthfully, I think we would both have to admit, that though we focus, concentrate, visualize..... in our heart - honestly - we don't think anything's REALLY going to happen.
      So it doesn't.
      When the great spiritual beings/guides/teachers of history said "you don't have to learn how - you have to realize you can, " that's IMHO what they were talking about. We have what amounts to a thin veneer of "wow, maybe" or "what if" lightly covering a great big thick slab of "this is ridiculous, there's no such thing!".
      Until we have that TRUE "eureka moment" and really *REALIZE* that it isn't ridiculous and there is such a thing.... well... that big thick slab of disbelief is what's shaping the subatomic structure of the universe.
      Right how the structure of creation is made of, "this will never work", and "what a lot of mumbo jumbo", and "what am I thinking, I'm not special", and "the truth is I'm a loser" and all the rest of that sludge accumulating at the bottom of who we are.
      That's "who" has to bend the spoon.
      The inner core.
      The inner core that really thinks it's ridiculous.

    I am humbled by the high caliber posts in here, excuse me if I come across totally wrong as I am just an amateur pulp physics enthusiast.

    I think science deals with the measurable. If a proof can not be derived by experiment then we have to refine our ability to observe or find a round about way of supporting a hypothesis. We, as humans only start with five senses but have increased our ability to detect by building new devices that expand our ability to measure. We can now see xrays, infrared and every other wavelenth of the spectrum now with our instruments. Does that mean we see it all? Science can not tell, it can only measure to be reproducible so as to be able to describe our environment, an important characteristic of science. I do like Lylah's example of the inability to measure a measuring cup using that cup within it. This may present one problem with our science coming at a roadblock. It kind of reminds me of useing a light microscope to be able to detect atoms, ...it cannot be done, but that does not mean we could not eventually succeed, ...by using new technology such as an electron microscope we have been able to see what we once thought was impossible.

    At one time we did not know if light was instantaneous or had a certain speed because of the state of our science being able to measure the world. As our machines improve we can now measure more and more accurately.

    If we start dealing with the unmeasurable as fact I feel we are starting to delve into the realm of faith and religion.

    I have heard many good things about the holographic universe A T, I think that will be my next book to read.
