Could you give an example of assigning one of the scalar to gravity?
jal said:Hi starkind!
Although your description sounds good, it still leaves a funny feeling.
I hope that the amateurs read and SAVE the doc from "Pierre Darriulat". Things have a habit of dissappearing from the web.
I have another bothering some question.
We have measured gravity down to the size of a hair.
We have gravity when we have matter/particles.
We can justify extrapolating gravity down to the size of quarks.
However, when working with scalars, there are no particles.
What is the justification for assigning one of the scalar to gravity?

Ha, ha - I'd call it a massless particle! You've probably heard photons referred to that way, and neutrinos certainly used to be called that, before they were interrogated and finally confessed that they had very small masses.jal said:Hi belliott4488!
My confusion.
A particle has mass and cannot go at the speed of light.
Therefore, what would you call something that goes at the speed of light.
Just trying to elliminate confusion.

What about the Z0 and W+/-? They mediate the weak force, but they are quite massive.jal said:... If it is a force or a field then it is massless and moves at the speed of light.
No objection, here. I'd just say that it's not the origin or location of the field, which is infinite in many cases, but rather the mediator of the force that is a particle. Close enough?jal said:First, gravity.
... There is a habit of naming the origin/position/location of a force/field as a particle and giving it a special name. In this case it would be a graviton.
I'm not sure exactly what you're getting at, e.g. when you speak of "manipulating the EMF" - that sounds like what I do when I turn on a light bulb - but again, maybe we're close enough in understanding that we can accept this and move on. One thing, though: I expected you to name the photon as the mediator of the EM interaction, similarly to how you named the graviton. Any disagreement with the comparison?jal said:Next, Electromagnetic force/field.
In this area we have named all kinds of origin/position/location and tried to classify them into patterns. As a result of using the particle concept for origin/position/location we have had great success in manipulating the EMF and gotten all kinds of technologies.
So far, no one has suggested that EMF is affecting spacetime like gravity.
You've used "origin/position/location" to refer to the mediating particles of the fundamental interactions, i.e. photon, W+/-, Z0, gluons, but the patterns that fit the gauge groups you name shortly really include the fermions that interact via these interactions, i.e. the charged leptons and their neutrinos, as well as the {u,d,s,c,t,b} quarks, (for SU(2)XU(1)), and the {r,g,b} quarks (for SU(3)). I would have mentioned them as well.jal said:Next, Strong and Weak Force.
Here, as with EMF, the concept of particles has been used for the origin/position/location of the field/force and again we have tried to classify the the origin/position/location into patterns.
There is? I'm not aware of this. I thought it was simply a result of the nature of the strong interaction.jal said:There is the suggestion that spacetime is affected because we have confinements of some forces/fields (The quark and gluons.)
Of course the pions are massive - you can look up their masses! They have to be since they are mesons, and as such are bound states of a quark/antiquark pair. Bound particles always have a binding energy, so even if the constituent particles are massless, the resulting composite particle has a mass equal to at least the binding energy (to first order, anyway).jal said:There is a suggestion that in the neucleons, the pions might also have some mass which would then mean that they would not be massless and we would be able to analyse them within a particle approach.
Yup. As long as you include the families of fermions, too, then I agree. Without them, the patterns are kind of empty.jal said:All of these patterns seem to follow some kind of symmetry SU(3) × SU(2) × U(1), ( E8?) and we refer to all of those particles as The Standard Model.
Well, I'm not sure what you mean by origin/position/location, but perhaps that will become clearer. Also, I'd balk a bit at your use of the word "speculation". While the Higgs boson has yet to be detected, the Higgs mechanism is a crucial part of the Standard Model, and there is no debate that I am aware of about how it fits there. Models beyond the standard model might well offer deeper explanations for the Higgs field, so perhaps that's what you meant.jal said:Next is Mass
Not too much is known. There is a lot of speculation.
The approach being used is a force/field which originates from a particle, origin/position/location, which has mass and that this force/field gives mass to the other origin/position/location particles.
That is referred to as the Higgs mechanism. Then the question becomes what gives the Higgs mass and where is origin/position/location of the Higgs?
As I indicated before, I object to the notion that massless particle are not particles, but if you want to think of them that way, then I guess there's no harm. We'll just have "particles" with mass and ... what? "field quanta" with no mass? I'm not sure what else to call photons, gluons or even the W and Z bosons before symmetry breaking, when they are massless.jal said:Finally, massless Preons, and massless scalars
At this stage we are looking at massless scalars or as some would call them massless preons where everything is moving at the speed of light. Therefore, there are no particles.
This is the study of spacetime, the early universe, and the investigation of possible structures. (E8? LQG?, LQC?)
This is where we find dark energy, Lambda, and vacuum energy.
A force that does not travel at the speed of light!What about the Z0 and W+/-? They mediate the weak force, but they are quite massive.
Another mystery … and possibly and explanation …. How to make a massless scalar obtain mass!Bound particles always have a binding energy, so even if the constituent particles are massless, the resulting composite particle has a mass equal to at least the binding energy (to first order, anyway).
It’s a good thing that there are “pros” trying to find possible structures (E8? LQG?, LQC?) that go beyond the Standard Model.I'm not sure what else to call photons, gluons or even the W and Z bosons before symmetry breaking, when they are massless.
What could have happened? Why, spontaneous symmetry breaking, of course! To wit, the Higgs mechanism. The most notable effect of the massive nature of the W and Z bosons is that it limits their range, thus the weak interaction is a short-range interaction, as opposed to E-M and gravity, which are both infinite in their reach (as far as we know today).jal said:A force that does not travel at the speed of light!
How can that be? What could have happened to cause that?
Just ask Prof. Higgs - he keeps the answer under his Mexican hat. ;-)jal said:Another mystery … and possibly and explanation …. How to make a massless scalar obtain mass!
