Re: An attempt to all the above in one post.
CD, indeed the Gnal interactions are weak within this cosmos, they are a 'residual' energy.
Higgs is 'hyped' as the particle of that somehow conveys mass and possibly gravity and gravitation.
There is no Higgs particle, there is an interaction and this interaction leaves a 'residual' energy we call gravity and gravitation and that interaction will be found and given the Higgs nomenclature for continued funding reasons as much as respect.
You are right to be skeptical and I am not fazed by it, but far from mysticism the FTL cosmos is there and will be accepted, mystics tend not to be definitive, I am quite definitive, No Higgs particle, just an interaction at FTL, an electron cloud re-defined as further evidence of this FTL interaction, EMR bound to form mass at ultra high energies that is stable and capable of continuous stable compounding moderated only by the available energy input.
If there is found a Higgs boson that is a particle a real particle of substance then I will be wrong in everything, I fall, mortally wounded, no recovery possible and I will be here to apologise and take the flak, that is only right, will you be able to do something similar if I am found to be right?
If the 'Higgs' is found not to be a particle but an interaction of something 'unknown' that happens at above light speed, will you then try to consider at least the possibility that what I have spent so much of my time on may be worth considering, you don't have to answer, if I know anything at all about you it is that you will want to know more.
I don't want sudden conversions, I want merely the idea [dismissed or not] to be there, dormant until such time as you alone find something that displays to you what I see.
That day will come.

Re: An attempt to all the above in one post.
Nothing you're saying is tied in to the real world. It's just a bunch of unsupported assertions. You're inability to tie anything you say to the real world is why you get asked to stop posting. After you've finished telling us how wonderful FTL maths are, how wonderful you are, and how posterity will one day prove you right, all while not mentioning a single fact, you're pretty much said everything you have to say, but you keep posting anyway.
If you want to get somewhere in discussion, use your theory to make a prediction that can be checked against the real world, or to explain a previously unexplained real-world phenomenon.
By the way, things like this:

My question would be just very slightly offtopic, not about expanding time, but about spacetime in string theory. In the official website of String Theory at http://www.superstringtheory.com, at one of the pages you could find something very curious:
"This is a hint that perhaps spacetime geometry is not something fundamental in string theory, but something that emerges in the theory at large distance scales or weak coupling. This is an idea with enormous philosophical implications."
The authors of the site intentionally omitted mentioning what those "enormous philosophical implications" are, probably so that they won't scare the general public before the ST is tested.
And since i've had most of my childhood "illusions" of material reality already crumbled to dust, i have no trouble accepting these implications.
One of the biggest one is that space and time are also made of strings, those string that make up everything that we perceive as material/physical or real.
String theorist prof.Sylvester Gates, of University of Maryland:
"Strings create everything, including space and time and even us."
But what about the prediction that spacetime is not fundamental..., this is really serious, but is a reflection of a holographic universe(this is the prediction of all 5 versions of the ST).
Where does the idea of the universe being a giant hologram come from? How is this related to the 1-dimensional strings, that have definite size?
I can see much logic to this prediction, as it solves all kinds of QM paradoxes.
What would string theory say about the source of this projection that gives us the illusion of a real, physical universe? The "thing" that's not allowed to be talked about on the science forums? How do we label this source/projector of our "reality"?
If you don't like to answer, i'll understand, just disregard this question.

No time right now but I will get back to this. The website is not the "official" wbesite fo string theory - there is no such thing. However, a quick glance shows me it is put together by the student of someone I used to know, and I expect it has good (or at least reasonable) content.
quote:
This is an idea with enormous philosophical implications.
No more or less than the implications I have already discusssed in reducing everything to the basic fields, including distance.
One of the biggest one is that space and time are also made of strings
That is very misleading and I would disagree with that.
quote:
"Strings create everything, including space and time and even us."
That is a more reasonable way of putting it, and I would agree with this (within the context of string theory being "right") - though even this becomes vague as we enter M-theory.
I can see much logic to this prediction, as it solves all kinds of QM paradoxes.
No, it doesn't QM remains exactly the same, with exactly the same weirdness and apparent paradoxes.

You mis-understand. If something is ill-defined, it is not a case that we do not know and it is open to speculation. We do know, it is ill-defined, and it is not open for speculation. There are many unknowns that are not necessarily ill-defined, and I am happy to speculate on these if I have the time.
I'll try to re-define what i said in an attempt to get you closer to my position.
Suppose the theory of the beginning of the Universe out of a quantum fluctuation was right. At T=0 the inside and outside of the universe measure the same - zero(i.e. there is no universe and no spacetime), so we kind of circumvent the "size has no meaning outside the universe" argument. At any moment after T=0 there is a metric expansion that "creates" expanding space inside, into itself. And any point one would pick from the inside would show on the antenna to be at relative rest(to the process of expansion) by observing uniform CMB from all directions you point you antenna, thus obeying the Hubble Law. So my question is this(and to me at least, it makes more sense than the FTL cosmos ) - is this a proper use of the metric in this scenario, pushing it all the way back to the quantum fluctuation?
Wouldn't this allow for countless numbers of other virtual universes, where everything and nothingness are both sides of an equation and differ only by the relative perception of the observer/measurement inside them?
I am asking this question as it kind of seems to fit the holographic universe model discussed above and supported by ST and gives a somewhat reasonable explanation for the something out of nothing scenario, where this something appeared to be ill-defined with the advent of QM(or more precisely mis-defined when taken out of the context of our animalistic perceptions and everyday experience).
EDIT: I now remember you explaing the expansion of the universe by a balloon analogy here at evc. However, if we are to picture correctly the balloon, its outside dimensions should remain the same throughout time(quantum fluctuation universe) while the balloon would expand almost indefinitely on the inside.
BTW what's the relationship between the zero energy universe and the CMB?

Cavediver, you might want to have a look at this paper that discusses my point about the universe being based on the holographic principle, predicted by the String Theory, while at the same time the author is tieing this to the Friedmann-Robertson-Walker metric in great detail and math.
http://arxiv.org/abs/hep-th/0203101
The holographic principle appears to give equivalence to matter/energy and information, but even if the whole of physics is fundamentally just information inscribed on the surface of the 2-dimensional boundery of a hologram, how can we consider this fundamental nature of our universe - a natural process? What would ever qualify as an un-natural process?
Isn't modern physics encroaching on metaphysics as discussed in various papers, while slowly departing from the concepts, predictability and intuitiveness of the Newtonian world, attempting to unite GR and QM?
As some famous physicist has said - how can nature be so absurd?

Cavediver, i'd like to get away for a moment from this mind blowing space/universe/separatedness of "things" being just an illusion of the mind(whatever that mind is - casually and loosely referred to as "observer" in QT) and focus on the philosophy side of it all.
So my question is - and this has been racking my mind for a while - do you still trust your reasoning? This will be mind blowing for the others but i am sure you understand quite well the question.
Can we "project" our animal newtonian reasoning and extend it beyond the appearance of the world and try to make sense of this illusional universe when we've come to find out that 1 object can be in multiple places at the same time? When the wave function of your body is spread out throughout the universe with different probability amplitudes of being in certain places? Are you doubting the animalistic perceptional "logic" inherent in humans that what we consider logic is actually that? That 2+2 is actually fundamentally 4 outside of our animal perception of the "world"? The fundamental nature of the world is not counter intuitive - it's completely f*cked up, it can be said to be counter intuitive only:
1. By people who have not understood what quantum theory says at all(as Niels Bohr said "Anyone not shocked by quantum mechanics has not yet understood it."
Or
2. By people who want to avoid scaring other people.
Do you think causality is a fundamental characteristics of this universe? I don't. How can we be sure of the infinite regress of that which i am not allowed to talk about on this sub-forum, when i am not sure that our logic is really logic at all? How can we seek the meaning of life when logic and reason fall apart beyond the scope of our primitive and decptive senses and all we are left with is the notorious "shut up and calculate" approach? When neurophysiologist Benjamin Libet has come to find out through experiments that free will is also an illusion of the mind. That decisions are taken fractions of a second before our brains engage in activities?
What about the f*cked up "movement" called quantum leap where particles move from A to B without ever going continuously all the distance from A to B but just jumping from A to B, while ceasing to exist while in transition*? Where particles(electrons, positrons, neutrons) pop into existence from somewhere(although i have no idea what somewhere means at all) for brief periods and vanish where they came from. Or where partciles can spin both ways at once? How can we ever reconcile this fundamental nature of reality to our inheritant, perceptional ape logic?
Do you still trust your reasoning and are you willing to bet it can ever take you to the answers about the ultimate nature of reality and finding out through reasoning or interpreting experiments if there is god or not, in a world described by the Bell's theorem(hailed as the most important finding of science) where absolutely everything, including you(whatever you are), is one wholeness(albeit virtual). I don't, i don't trust my reasoning beyond my projected everyday experiences and i agree with Feynman that:
"... 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."
We really don't know that much and what's worse we have no idea if what we know is applicable in any way to answering the grand questions of our existence or whether it's right at all or whether it's not simply a delusion set up so that it would appear to make sense to us in our primitive fight for survival or simply lead us like sheep down a pre-defined path. IMO thinking about those unanswerable questions that this board is set up for, is just a hilarious and heroic waste of time while we are bound to this interface we call "human body and brain" which experiments point to lacking free will.
I used to believe, and it's evident in old posts of mine, that science could in time reach god. I don't hold that view anymore, my viewpoint shifted close to that of Schroedinger who was convinced that physics can provide absolutely no answers to philosophical questions. I don't even think anymore that logic, as we think of it, applies to philosophical question while we are using this deceptive and limited interface. Or as Brian Green puts it:
[i]“Human experience is often a misleading guide to the true nature of reality.”
I'd very much like to hear your opinion on this philosophy of physics aspect, even if i get suspended i'd be still be having an occasional look at the forum.
* Michio Kaku is making his students in the University of New York calculate the probability that a person will wake up on Mars through the Schroedinger equation. The chance is very very slim but is not zero . This is the same as why a ball has a chance different than zero of passing "through" the wall instead of bouncing back(aka quantum tunneling).

At T=0 the inside and outside of the universe measure the same - zero(i.e. there is no universe and no spacetime)
No. If I don't have a ball, it's size is not zero! If I don't have a universe, it's size is not zero. In both cases, the size is undefined. This is a very important point.
And there is no outside 'size' - it is undefined.
so we kind of circumvent the "size has no meaning outside the universe" argument.
No, you don't. Saying something is zero is a very specific statement. You cannot make that statement about things that do not exist!
At any moment after T=0 there is a metric expansion that "creates" expanding space inside, into itself. And any point one would pick from the inside would show on the antenna to be at relative rest(to the process of expansion) by observing uniform CMB from all directions you point you antenna, thus obeying the Hubble Law.
Yes, this is true. The CMB does define a frame-of-rest for the Universe.
Wouldn't this allow for countless numbers of other virtual universes, where everything and nothingness are both sides of an equation and differ only by the relative perception of the observer/measurement inside them?
If the Universe is a 'quantum fluctuation', it must be a quantum fluctuation in something - some larger level of existence. The physics of this larger existence will govern the creation of universes. But yes, in this very sketchy concept, there would be many universes.
I am asking this question as it kind of seems to fit the holographic universe model
No, it doesn't really have anything to do with Holographic Principle.
its outside dimensions should remain the same throughout time
This is how you could visulaise it, but it has absolutely no physical meaning (unless embedded in some larger theory)
BTW what's the relationship between the zero energy universe and the CMB?
Nothing really. The CMB is simply made from the first photons in the Universe to move freely through the Universe. This occured about 400,000 years after the Big Bang.

This is incredible - it compares to the middle ages where Galileo proved the Earth was not flat, as was commonly believed up to that point.
Einstein on the Optical Illusion of Separateness
"A human being is a part of the whole called by us "the universe," a part limited in time and space. He experiences himself, his thoughts and feelings, as something separate from the rest - a kind of optical illusion of consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening the circle of understanding and compassion to embrace all living creatures and the whole of nature in its beauty."

But to me this is misleading or i don't understand something - what you are saying suggests that a non-existing ball can have a size that's different to zero. To me "undefined" leaves room for other numbers beside zero.
cavediver writes:

But my common sense tells me that zero apples means there are no apples. I am aware that "nothing" is very hard to define and grasp in a universe of infinite wave-functions(a particle with precisely known momentum). It seems you are saying that human common sense should not apply.
cavediver writes:

Yes, i worded it wrong. I meant that it ties in with the optical illusion of separateness of "things" in the universe and the zero 3D size described by the Holographic principle.

No, absolutely not.

It is not the value of the size that is undefined, it is the concept of 'size' itself.
But my common sense tells me that zero apples means there are no apples.
True, but the zero here is a property of the set of apples, not a property of the apples themselves. If you have no apples, what size are they? And what colour are they?

This is drifting from the point i wanted to discuss. We agreed that this is true:

And any point one would pick from the inside would show on the antenna to be at relative rest(to the process of expansion) by observing uniform CMB from all directions you point you antenna, thus obeying the Hubble Law.
What i was saying is that at any point in the past, say 5 bln., 10, 13bln years ago, any point you would pick from within the universe would show uniform CMBR. That is, this backward process would hold true until the universe reaches the Planck length. From this point on it really becomes undefined, but my common says after the Planck length comes zero.
Hence, i suppose that from this impossible outside perspective, the universe would have zero size. Do you find fault that zero makes sense to a human being, when this concept of nothingness is not supposed to make any sense or succum to mathematical description?

Zero size + zero colour. I equate zero with non-existence, i would not talk of apples if they were zero. It's our human imagination that has the ability to project fictional apples that don't exist and fictinally ascribe mathematical properties like size, or subjective properties like colour. The solution to this is how consciousness works, but i don't have an answer for that.

If the whole western world believed the amoeba had a nose, all it would take to prove that the amoeba doesn't have a nose is to show mathematically, within the framework of the known laws of physics, that the size of the nose of the amoeba is zero.

I hate to be the one who brought "exist" to the debate as it's bound to drift the topic to interpreting dictionary definitions, POV's and generally making a mess out of any thread.
It seems cavediver is saying that the universe does not have an outsize size and i am saying this size is zero(whereby i acknowledged from the beginning that this outside of the universe viewpoint was impossible).
What i meant to show was the universe would not exist if there was such an outside viewpoint and if some other dimensional entity existed in what we generally refer to as "nothingness". In whichever way we word this, it all comes down to the same conclusion that there is an illusional appearance of size and separateness only from the inside of what we call a universe. I have no idea how this works but if we take Einstein's word for it from the above quote, it's "a kind of optical illusion of consciousness"
