    on the religion forum I was describing what I thought was quantum physics...that the universe is accelerating and expanding in a spiral. Is that quantum or something else or combination of things...?

    Quantum physics is a set of laws believed to be followed by all things in universe, but is generally particularly apparent on the scale of atoms and such. Therefore, what you described is probably more in the field of relativistic physics (we could put some arguments here regarding what I just said, but more or less and trying to be short - you were not speaking about quantum mechanics phenomenon). Maybe it's best to say, in the end, that it's a combination of things. Hope this helps smile

    I appreciate the attempts to help. The things that I have read through the years have developed a "life" of their own in my memory, not remembering specifically where each component came from, let alone able to seperate out each !smile
    To really give you a look at that "life" that has developed, here is  a statement/question...
    Everything in the universe, in all dimensions, is make up of light. Light is vibration, there are different levels of vibration within the spectrum of light, that create the colors. You know the rainbow colors are of the white light.
    And sound is vibration, too. So each color has its own sound/vibration ! right?
    So, is this connected to the expanding and accelerating in a spiral universe?

    Maybe I need to start a new thread with a different question? smile

      protjackposted 15 years agoin reply to this

      Hi there. Light is the "vibration" of the electromagnetic field and sound is the vibration of particles of air, materials or other media, so it's not the same and you cannot connect it so easily as you have done.

      To add one more thing, to the best of my knowledge, the statement that everything is made of light is not nearly true.

        SparklingJewelposted 15 years agoin reply to this

        Would you explain more or recommend a book or website that would be good for a novice to read and learn from concerning light,color and sound.
        As well as address that everything is not made up of light...what do you mean? any reference to other reading?
        We probably should start another thread with it.

          Well I've studied from books used at college, so you probably don't want that and I can't think of any popular science books on this subject, not familiar with them. Maybe start with Wikipedia.

          Well light is photons and there are many other elementary particles like electrons, neutrinos, muons... Universe is made up of all of these, not only photons (i.e. light).

    This is complements of

    Quantum physics is a branch of science that deals with discrete, indivisible units of energy called quanta as described by the Quantum Theory. There are five main ideas represented in Quantum Theory:

       1. Energy is not continuous, but comes in small but discrete units.
       2. The elementary particles behave both like particles and like waves.
       3. The movement of these particles is inherently random.
       4. It is physically impossible to know both the position and the momentum of a particle at the same time. The more precisely one is known, the less precise the measurement of the other is.
       5. The atomic world is nothing like the world we live in.

    Misha is right. Quantum physics deals with the very small not the larger aspects of the universe. They are particularly interested in wave/particle duality. Which was talked about on the other thread briefly. Hope this helps. Need to get some sleep. Good night all. big_smile

      ZEVposted 15 years agoin reply to this

      Yes, your right, and in particular to my comment on the religious thread; "I take a quantum physics approach to religion" deals with the wave/particle duality. This means that I may be able to experience two realities at the same time. If your looking at heaven then heaven is here and we are in heaven at the same time. That's about as simple as I can explain it.

        SparklingJewelposted 15 years agoin reply to this

        So, you mean like when someone is in a state of higher consciousness in prayer or mantra, they are experiencing "heaven" while their body is still in this plane. so heaven is here, through this person's consciousness state and fills his electromagnetic field, integrated with the physical state?? or something like that ?

    Richard Feynman: Quantum Electrodynamics (QED)

    I think it is safe to say that no one understands Quantum Mechanics. (Richard Feynman)

    One does not, by knowing all the physical laws as we know them today, immediately obtain an understanding of anything much. (Richard Feynman, Quantum Mechanics)

    The more you see how strangely Nature behaves, the harder it is to make a model that explains how even the simplest phenomena actually work. So theoretical physics has given up on that. (Richard Feynman, Quantum Mechanics)

    The next question was - what makes planets go around the sun? At the time of Kepler some people answered this problem by saying that there were angels behind them beating their wings and pushing the planets around an orbit. As you will see, the answer is not very far from the truth. The only difference is that the angels sit in a different direction and their wings push inward. (Richard Feynman, Character Of Physical Law) … quotes.htm

    so quantum physics is like saying, when you sneeze it can effect something either emediatly, like myself, or before I even acknoledged I was going to sneeze and then effecting someone on the other side of the planet, who in turn caused a million people to sneeze one after the other, and then somehow caused an atomic change or shift in reality, which is no different today then it was yesturday, and all those photons or light particals that are reaching us now from space could quantumly speaking have an effect on our behaviors, viruses, and such, but nothing ever changed, it was always there to begin with, it just works in pattens.  Right???

  12. Lifebydesign profile image63
    Lifebydesignposted 15 years ago

    Quantum has to do with the dynamics and principles of the smallest particles that matter is made up of ie what triggered the sneeze in the first place on a subatomic level.
      The first concept is that there's more gaps and spaces in the world than there are particles. If you were to take out all that space then all the matter in the world would theoretically fit into a teaspoon (and be massively heavy).
      Secondly what determines heaviness and solid matter is the arrangement and density of the particles but the particles themselves are interchangeable and don't really belong to any one particular object.
      Thirdly what we perceive to be reality is only based on what we believe reality to be.  Reality isn't real, it's determined by what we think it is, according to quantum. So a light particle will behave like a particle or a wave depending on what the observer believes light is. If he thinks its a particle, it behaves as such. If he believes it wave, he sees it behave like a wave. Schroeder's cats was a 'thought' experiment on the same thing.
      But in mainstream life it's translating into a kind of everyday language as people grasp the possibilities that quantum is demonstrating. The 'law of attraction' for example is also based on this principle of the observer; you get in life what you believe be it poverty, wealth, whatever.

    This is such a big topic- really recommend 'What the bleep do we know' on DVD and it has a sequel 'Down the Rabbithole' - great for the layman and a good foundation for this stuff!

      Down the Rabbit Hole was really good.  Fascinating how observation seems to be the only truth we think we know.  Also fascinating is how just by looking at something we distort reality, or cause reality to shift for no apperent reason.   

      Have you ever tried to look at space, and instead of looking at the stars or light objects, focus on the dark matter inbetween?  Looks like either,  we are showering space with light from Earth, or space is raining black waters. 

      Anyways, it is a good subject.

    Shaur onlineposted 15 years ago

    Dr. Richard Feynman, nobel prize winning quantum master, wrote a marvelous little book called QED The Strange Theory of Light and Matter, which I think is as close to a discussion in layman's terms as it gets.  Basically, quantum dynamics is an expansion of the theory of quantum mechanics, which redefined chemistry in terms of the electrical interactions of molecules and tries to incorporate the physics of electricity and magnetism into it, creating a more unified theory.

  14. Inspirepub profile image72
    Inspirepubposted 15 years ago

    If you want to grasp Quantum Theory, start by getting a good high school math textbook and understanding probability theory. If you don't "get" probability accurately at a gut level, you have no hope of ever grasping even the first piece of Quantum Theory.

    In particular, you need to understand - what is a probability distribution, for example a bell curve, and the difference between probability before something happens vs probability when you are looking backwards in time.


    P.S. Once you have that mastered, grab Stephen Hawking's "A Brief History of Time" and get your head around that.

    sandra rinckposted 15 years ago

    lets say you could wrap your mind around, umm...the now as a quatum physic.  We advanced foward and backwards so fast, we live in the now.  The past and the future exist in the same quantum moments.  We continue on the same forwards, backwards momentum (pun intended) but we aren't fast enough to catch up to the quantum future nor slow enough to catch up with the past.

    So does quantum theory, or quantum something, have anything to do with a spiral? Isn't the universe/galaxy in a spiral?

    In my spiritual studies, I see life as a spiral, ascending or descending. Each year we come back around to the same point on the spiral, either at a higher or lower level of the spiral, hence, experience similar circumstances, awarenesses, tests, initiations, that we have before; except that it is with additional information because of a new higher level, or a repetition at a lower level with just a different circumstance, but the same test to learn.

    Like astrology/astronomy, or anything in creation. The same things happen, day becomes night, planets go round in their orbits, summer is after spring, we have our birthday at the same time each year...but all aspects at that point can be different.

    or like dealing with psychology and developmental stages of growth. Something happened when we were a child, that created a particular response to a particular kind of now every year at that time or every time a similar circumstance happens, we "go into" that response that we had from the initial interaction.

    Does anyone else see things in a similar way?

      sandra rinckposted 15 years agoin reply to this

      very similar.  I see the Universe and hidden life like this as well.  But spiritually, we are in the now, next time will be lived in the now.  but yeah, very much like that.

      I see it as a spiral too- at least in the way that we progress on an individual level (which can be extrapolated on a larger scale to society etc) - but definitely, to me we're always moving upwards.

    The most interesting thing about it is the fact when plugging the formula of relativity into a quantum discussion of travel.  There is the theory about entering the light realm where light weighs 0, the e=mc2 formula still works for light travel and can surpass that speed.  You get into all kinds of great discussions then.

      sandra rinckposted 15 years agoin reply to this

      I would think that in order to weigh absolute zero it could neither be light or without light.  Dark energy or matter seems to be the only thing that can exceed the speed of light.

    My question is, if you're driving in a car that can drive the speed of light, and you turn the headlights on, do they light up?

      LOL!  Something to consider.
      does anyone know??

  22. crashcromwell profile image68
    crashcromwellposted 15 years ago

    I think they would light up, but you wouldn't be able to see the light unless you climbed out on the hood of the car and bent over the front to look at them, which, by the way, would be incredibly foolish to do in a car moving that fast. But that's another topic........

    1. Lifebydesign profile image63
      Lifebydesignposted 15 years agoin reply to this

      oh of course,yeh you're right, and they'd light up at the same time. Just because the car was travelling at the speed of light doesn't mean they wouldn't turn on when they're supposed to.
      I imagine the light would travel at the same speed too right? As soon as you turned them on while the car was travelling, they would light up any objects in its path at the exact same time- that is the speed of light- and not any faster or slower.

    In lamans's terms quantum physics is the study of everything small, for example atoms, particles, newtrons and electrons, the theory of relativity is the study of everything big for example stars and planets, the trick is to connect the two with one another, which can explain black holes. maybe alittle off topic here.
