Topic: Many Worlds Theory

I posted about the concept of probable worlds in the Current Events forum (Holocaust Survivor Leaves US--Sees What's Coming). 

It seems to me that the "one world" illusion is remarkably persistent. With this point of view, then when we hear about plans for the NWO,  we may think it will inevitably occur in our world.    Various channeled sources have stated that the world is splitting, and that people will find themselves in the world that fits with their vibration. 
But how many of us take this idea seriously?

Anyway--here's some scientific confirmation that there is not just "one world."

Hugh Everett III and the Many Worlds Theory
The Macrocosm of Many Worlds

Our known universe is defined by two transformations. In the first all the strange and chaotic futures we might imagine do not happen because of nature's consistent laws and forces. Primarily gravity, electromagnetism, the strong force, and the weak force, remove from possibility all of what we would think of as weird or irregular events. The forces of nature create a wonderfully predictable world where the sun rises and sets each day.

However, if we think about it, we can reason that there must be many other unique morning and evenings that don't happen here in our own world, and all are reasonably as possible as the one world we experience. Why don't they exist? Do they exist elsewhere? If we utilize the same laws and forces of nature, we can conceive of many other paths of time, or many tomorrows, all happening in other worlds.

Each one of us who has ever contemplated the universe has at one time wondered why our one world would exist when all the others as equally possible never made it to the party. It is when we study quantum mechanics that we find nature acknowledging all those other worlds that are equal in possibility to our own.

The other possibilities had not been visible within the more mechanistic Newtonian and Relativistic world views. Newton viewed the world as if it was like a giant machine, such as a clock with gears that produce a single precise outcome. And Einstein viewed the world as a solid existence, an undivided path from past to future. But what is imagined as possible by science, beyond the one world we experience, increased significantly after we discovered that all the small particles that collectively construct our world, travel through space as probability waves. Instead of solid motion from point A to point B, like a thrown baseball, particles transfer into a world of probability. Within each wave are an infinite number of positions a traveling particle moves through, and until the particle interacts with something else and then takes a physical position in reality again, the particle is said to not have a single or definite position. Rather the one particle becomes a blaze of paths we describe in science as a quantum wave of probability.

Of course when scientists first explored the atomic world they naturally expected to find individual particles moving through space just like larger objects. They expected electrons would orbit the heavy proton nucleus just as smaller planets orbit the sun. But instead, they discovered that atomic particles virtually transform from solidity to probability in order to travel from one place to another.

We began to understand the strange way that everything tiny travels from place to place when Werner Heisenberg discovered at the beginning of this century that we can never know both the momentum and position of matter or light particles. Heisenberg, Erwin Shrodinger, and Paul Dirac, with later help from others including Albert Einstein, were eventually led to formulate quantum mechanics, beginning a revolution in Physics that has completely changed the way we see the unfolding of the future, and even the past. Quantum theory explains that until we actually observe the past, the world is in a state of simultaneity where the finite events we assume are always finite are still blended together with all the other possible worlds we haven't observed and won't observe. In other words, until we observe a particular past, the past remains fused together and so part of the infinite.

This aspect of the universe was first presented as science in a journal paper written by Hugh Everett III, who was at the time a student of John Archibald Wheeler, a renowned American physicist and longtime Professor at Princeton. In recognizing that each particle of the subatomic realm travels as a wave, simultaneity would apply to every possible outcome of each quantum event. Everett considered that the universe is not limited to the one reality we observe, and instead that all the other possible worlds branch away from every possible particle event and thus many other worlds or branches of time exist just as real as ours does.

No idea expresses the quantum world more vividly than Shrodinger's cat. To illustrate the absurd multiplicity of quantum theory the physicist Erwin Shrodinger created a vivid thought experiment, where he places his cat within a delicately rigged box. Inside the box is a radioactive atom that has a fifty percent chance of decaying. If the atom should decay it will expel an electron particle that will register on a Geiger counter, also inside the box, and the machinery will then break a glass vile of cyanide gas, killing the cat.

The life or death of the cat is used only to dramatize the multiple states of a quantum wave. We know from quantum mechanics that until we observe the atom by opening the box, it remains in a wave-like state. Being a wave it exists in multiple states so it has decayed in one world and remained stable in another. It essentially exists in both states simultaneously. Since the state of the atom is a blur of probability, as odd as it seems, the state of the measurement device also becomes a wave of probability, existing in multiple states at once, which further means the wave is even extended to the cat. The cat itself becomes a wave of probability both alive and dead.

Of course the state of the cat can be interpreted in one of two ways, both of which define reality in dramatic fashions. We can be conservative and say the decaying particle existing as a wave is not real, meaning that it has neither decayed nor remained stable until we open the door of the box, but this then means that the cat is neither dead or alive. Being conservative means saying the cat somehow doesn't really exist until we observe it.

If we don't try to avoid the fact that two realities are obviously existing simultaneously, then we say the particle has decayed in one reality, and remained stable in the other reality, so that two conflicting realities exist, but neither is connected to our observer standing outside the box. Only when we open the box to observe the dead or alive cat, do we find ourselves in one of the two realities.

In one choice we try to say that the cat is neither dead or alive and so is not real, existing only as probability until we look inside the box, although then we must wonder about the experience of the cat inside the box. With the second choice we say the experiment has created at least two cats, one is dead and one is alive, and each exists in separate worlds. As we open the box we connect through our interaction or observation with one of those realities.

In either case what is suddenly being defined as we open the box is not necessarily only the future. After all it is what has happened in the past that is collapsing into a single reality as we open the box to observe the condition of the cat.

In the first interpretation if we insist on avoiding the profound but obvious conclusion that before we observe the cat there are at least two worlds just on the other side of the closed door, then we destroy the chain of cause and effect, and we loose all sense of the world being solidly real, then we egocentrically resolve that we ourselves create reality as we observe events. All this without yet resolving the problem of what the cat observes from within the box. And if we are arrogant enough to say that the cats observations aren't as real as our own, claiming that it takes a human observer to create reality, which is a claim that your cat at home doesn't exist when no one is observing it, we then place the person making that claim in the box and start over.

Clearly, the only sound alternative is the second interpretation, where both outcomes are real, and we become a part of one of them. But then as we study this more carefully, it is not simply the space inside of the box that is splitting into two realities. The outside world as we open the door to observe the cat, and so we ourselves, split into two principle realities. In one we exist observing the cat alive and in another we also exist observing the cat as dead. We don't simply find ourselves in one of the realities, we exist in both as time itself branches.

So we are given a choice. We can either sacrifice reality as we know it for a hollow probable world, or accept reality as much grander than even an imaginative person is normally comfortable with. This may be why, after Heisenberg first developed the uncertainty principle, that it wasn't until 1957, some fifty years later, that Everett developed the first formal theory that began to describe many other worlds. His doctorate thesis on the subject was dubbed the Many-Worlds interpretation of quantum theory and has been considered a valid scientific theory ever since.

The Second transformation

The first transformation eliminates all the weird or abstract worlds we might find in a science fiction movie. It cuts down infinite possibilities to a specific set of worlds, a set that is defined by the laws and forces of nature. This leaves us with what we would normally imagine as possible. The second transformation then is when that group of many possible worlds is transformed into the single world we live in.

Primarily, it is the speed of light and four forces which define the wave of many worlds, and as time passes, enough particle waves collapse to create a single defined reality, and that is the world in which we live. What then are we to think then of all the other possible outcomes which represent the paths of space-time we do not experience.

If you were to peer into these parallel worlds you would see yourself move in every possible direction. Your arm will raise and lower, your legs will move one way and the other. In the next few moments you will sit up, stand up, lay down, and stretch from head to toe. Each other world is only slightly different than the next possibility, each having only an infinitely small difference. If we were somehow aware of all the other branches of time, almost instantly one's surroundings would burst into a solid blur of mass and energy. Looking back in time we would see a dense wave of all the many worlds formed since the Big Bang.

Some scientists shrug at this, and continue to believe there is something that makes quantum reality only work at the micro level. And since it is not easy to prove otherwise by scientific testing the absolute truth of either hypothesis, the result has been that science itself is in limbo waiting for more evidence. It's almost as if science has developed a phobia, avoiding what is simple and even sensible.

The consequences of the quantum wave is indeed very profound and has already made a tremendous impact upon society. In addition to television shows and movies where characters cross over into parallel worlds, physicists have been given the chance to act as philosophers, debating over the structure of reality and the role of the observer. What is agreed to be certain is that the universe is not a single solid world of moving objects, there are many worlds that at least exist as potential, and we, rather than simply observe an external reality, to some degree partake in its creation simply by opening our eyes.

Re: Many Worlds Theory

Thanks, that was an interesting article. Of course with a change in the understanding of quantum physics comes a change in what conclusions we can derive from it. Here's an example:

New model 'permits time travel'
By Julianna Kettlewell
BBC News science reporter

http://news.bbc.co.uk/2/hi/science/nature/4097258.stm

If you went back in time and met your teenage parents, you could not split them up and prevent your birth - even if you wanted to, a new quantum model has stated.

Researchers speculate that time travel can occur within a kind of feedback loop where backwards movement is possible, but only in a way that is "complementary" to the present.

In other words, you can pop back in time and have a look around, but you cannot do anything that will alter the present you left behind.

The new model, which uses the laws of quantum mechanics, gets rid of the famous paradox surrounding time travel.

Paradox explained

Although the laws of physics seem to permit temporal gymnastics, the concept is laden with uncomfortable contradictions.

The main headache stems from the idea that if you went back in time you could, theoretically, do something to change the present; and that possibility messes up the whole theory of time travel.

Clearly, the present never is changed by mischievous time-travellers: people don't suddenly fade into the ether because a rerun of events has prevented their births - that much is obvious.

So either time travel is not possible, or something is actually acting to prevent any backward movement from changing the present.

For most of us, the former option might seem most likely, but Einstein's general theory of relativity leads some physicists to suspect the latter.

According to Einstein, space-time can curve back on itself, theoretically allowing travellers to double back and meet younger versions of themselves.

And now a team of physicists from the US and Austria says this situation can only be the case if there are physical constraints acting to protect the present from changes in the past.

Weird laws

The researchers say these constraints exist because of the weird laws of quantum mechanics even though, traditionally, they don't account for a backwards movement in time.

Quantum behaviour is governed by probabilities. Before something has actually been observed, there are a number of possibilities regarding its state. But once its state has been measured those possibilities shrink to one - uncertainty is eliminated.

So, if you know the present, you cannot change it. If, for example, you know your father is alive today, the laws of the quantum universe state that there is no possibility of him being killed in the past.

It is as if, in some strange way, the present takes account of all the possible routes back into the past and, because your father is certainly alive, none of the routes back can possibly lead to his death.

"Quantum mechanics distinguishes between something that might happen and something that did happen," Professor Dan Greenberger, of the City University of New York, US, told the BBC News website.

"If we don't know your father is alive right now - if there is only a 90% chance that he is alive right now, then there is a chance that you can go back and kill him.

"But if you know he is alive, there is no chance you can kill him."

In other words, even if you take a trip back in time with the specific intention of killing your father, so long as you know he is happily sitting in his chair when you leave him in the present, you can be sure that something will prevent you from murdering him in the past. It is as if it has already happened.

"You go back to kill your father, but you'd arrive after he'd left the room, you wouldn't find him, or you'd change your mind," said Professor Greenberger.

"You wouldn't be able to kill him because the very fact that he is alive today is going to conspire against you so that you'll never end up taking that path leads you to killing him."

This model is several years old, here's the paper from 2001:

http://citeseer.ist.psu.edu/508386.html  (click on PDF in the top right)

Some excerpts:

So, according to our model, in quantum mechanics, if one could travel in to the past, one would only see those alternatives consistent with the world one left. In other words, while one could see the past, one could not change it. No matter how unlikely the events are that could have led to one's present circumstances, once they have actually occurred, they cannot be changed. One's trip would set up resonances that are consistent with the future that has already unfolded.
   This has consequencies on the paradoxes of free will. It shows that it is perfectly logical to assume that one has many choices and that one is free to take any one of them. Until a choice is taken, the future is not determined. However, once a choice is taken, it was inevitable. It could not have been otherwise. So, looking backwards, the world is deterministic. However, looking forwards, the future is probabilistic.
   The model also has consequences concerning a many worlds interpretation of quantum theory. The world may appear to keep splitting so far as the future is concerned, however once a measurement is made, only those histories consistent with that measurement are possible. In other words, with time travel, other alternative worlds do not exist, as once a measurement has been made, they would be impossible to reach from the original one.
   Another interesting point comes from examining eq. (37)...Thus less "deterministic" and fuzzier time-travelling might be possible.
    We summarize by stating that the structure of a quantum time travel through Mach-Zehnder device is rich and unexpectedly elaborate. This suggests totally new scenarios for the possibility of free will and the capacities available to an agent acting in such a time loop.

Interesting stuff.

"...Once a measurement is made, only those histories consistent with that measurement are possible" -- question is, given a measurement, how many histories are consistent with it? Put another way, if you have made X amount of decisions in your life, would time travel allow the past to be switched to a different but consistent history that would artificially bias your immediate future, through negative synchronicities?  Other questions...if time travellers cannot change a particular past, they can still observe it as long as they don't actually interact with it. So if certain other-dimensional entities wanted to watch us right now, they could do so without problems if they stayed invisible.

Acquiring fringe knowledge is like digging for diamonds in a mine field.

I am more of the mind that if you change the past, then you are pushed into an alternate dimension, where the future isn't the same.  It may, however, be consistent, but that would mean that the time-travellers memories would be different.  The only way to keep it consistent would be to enact certain activities in easily containable incidents, but that would still imply that the past cannot be altered once it has been measured.  For example, once you travel to the past, you are a part of your dimension's future's past, so anything you do has been done.  If you alter that past, then you are in another dimension.

Of course, this all falls apart in quantum theory.  However, whether it has been measured or not, in my opinion, doesn't change anything.  Either the cat is dead or not, and simply not knowing doesn't make me believe that there are alternating dimensions.  I doubt the mind has enough bias to make certain realities true and others false, even with the explanation that "we aren't wise enough to understand all the things that happen".

I've thought about this one, and it seems quantum theory is another semantic spook, a phrase that means nothing beyond the concept.  It's also akin to a dogmatic view of God, in that all inconsistencies begin to exist in a realm of "beyond our understanding" in a quasi-state of existence that explains any possibility.  It seems another way to avoid any real solidification of reality because it leaves a doubt, even if not beyond a reasonable one. 

While the omniverse may be open-ended, universes may be linear.  Of course, if universes interchange every once in awhile, it may explain the metaphysical aspects of our reality and supernatural occurances, as well as the appearance and disappearances of people and whole civilizations, and things such as ghosts and ufos.  They simpy phase in and out through a compatibility of different universes.  We could be floating in and out of different universes all the time.  In fact, maybe the reptiles are trying to bring about this compatibility.

On another note, I'd love to see a movie/book/show that actually dealt with time travel and covered all these loopholes.  Every one I've seen have had holes!  The pondering of the paradoxes of time travel is something of a passionate hobby of mine.

Re: Many Worlds Theory

The thing that sticks out to me more than anything else with the time  travel article is the writer's fascination with killing a father.
