Any time you see a sun flare you see a interaction between radiation and matter, as far as I know. You need some type of rest mass. But a Big Bang, without rest mass? How did it ever get to producing it? From what type of reaction? Energy + energy = rest mass, can't be right. Radiation + energy then? Makes no more sense to me :) Radiation + Radiation then. Really? And from where did we get that radiation?

Actually, the last one isn't that stupid. It just depends on how you define a universe.

Everything is possible to translate to the coin of exchange, 'energy'. But you have to be pretty mixed up if you define matter and photons, radiation, as one and the same. They are not the same.

Yes, I know of waves interacting :) quenching and reinforcing, as in a two slit experiment, and I will need to write about that too. But photons do not interact as far as I know. And you need to set it into my world view, in where locality is all, well, all I go out from that is. But I really need to write about waves too.

Another thing. I wrote that Higgs doesn't explain rest mass. that depends maybe. Assuming you believe in 'real' virtual particles, with a momentum discernible by a Higgs boson/field? And if we to that add that those imaginary directions take themselves out?

Well, curioser and curioser possibly, but who knows?
I just don't find it good enough.

Alternatively, assume that everything 'vibrate'. Atoms, their particles, electron clouds, whatever rest mass you can think of. We need to impose the same restriction naturally, that those directions they may present 'vibrating', evens out. then you could possibly argue that a Higgs field react with it, creating a mass. Naturally we then need to assume that some bosons, as photons, shouldn't 'vibrate' too, as it (a photon) has no discernible rest mass. It can't have it, it's never 'at rest'.

So, momentum or position :) A Higgs would then 'see' what?
Why?

Thinking of HUP.

Would you then need a 'container model' explaining this field? Or can you do the same without? If you believe HUP then there is probabilities that define what we see. there are no certainties, although possibly decoherence can be seen as a try for a, statistically defined, certainty, all as I get it.

It's not the Higg's per se that gets me frustrated :) It's the thinking behind, the presumption of a container it implies to me.. What defines this universe is not a container, it's logic.

How about this then. I had an idea, old one, about this being a flickering universe. You could translate that into a discrete model, where it all becomes quanta that flickers, of and on, at for example Planck scale. To that add that motion then represent differing positions in this 'field'. Planck scale seem a natural choice for it. What would a Higg field be then?  Maybe a flickering can be translated into motion by a Higg? but it does not fit. The Higg fit a model in where you presume, preexisting, dimensions, in where we find a field, or rather several types of fields, that together create our rest-mass, and our reality. Because the Higg does not explain particles, it's here to explain inertia, and possibly gravity.

How do I translate a Higg field to a photon following a bent path, passing our sun for example? It has no mass, you can argue that it has a energy naturally, equivalent to a mass. but why would a vacuum give that path if the reason to gravity it this field, acting on particles? To answer that you could argue that the 'vacuum energy' close to a rest mass must stronger, think of a event horizon and spontaneous pair production for that. And so producing a higher amount of 'virtual particles' that a Higg field can interact with, creating that photon path?

I don't know, I don't like 'virtual particles', especially as they only exist in combination with rest mass, as far as I've read, experimentally. you want a vacuum to have it, then please find some way to prove it from a vacuum, not from interacting with rest mass. It's like photons 'propagating', no way to prove in unless you define source and a sink of matter, as there is no object as a 'photon' measurable in itself, unless in a annihilation. Which to me always will be a very local experience. Then we have waves, they demand frames of reference to exist, if something really should be said to 'propagate' then I would think of waves firstly.

That takes us back to the initial moment of a Big Bang :)

Without rest-mass, and also without radiation?
How would energy, if that now can be assumed to exist as some entity, on its own, produce it?
Relates directly to if you should be able to prove 'virtual particles' without matter interactions.

So what am I saying here? That this universe you experiment on can't be the one creating it? Alternatively, prove virtual particles, without involving matter interactions, that should give you a good argument for 'energy' being able to create the rest.

So what does the Higg rest on? The standard model? And the results from LHC? And, maybe, also on the presumption of virtual particles able to interact with it? That is if you want it to relate to rest mass in uniform motion, also called relative motion.

Read this one first http://scienceblogs.com/startswithabang/2012/07/03/the-biggest-firework-of-them-all-the-higgs/

then this http://www.huffingtonpost.com/2014/04/03/higgs-boson-particles-techni-quark_n_5085812.html

seems I wasn't too far from how some think when it comes to 'virtual particles'?

no surprise there, it's all about a container model, isn't it? real 'motions', of 'real', as well as 'virtual' particles, treated the same way. Ignoring the logic that states you can't use that model, unless you ignore relativity's observer dependencies. Shouldn't the mass measured then, change with ones (relative) motion in a vacuum? the whole idea of force carrying particles moving around as unmeasurable bosons seem to crave a simple container model.

To me it seems diametrical to what relativity state about motion. That it is observer dependent. You are free, in a uniform motion, to define that 'relative motion' any way you like, from being still to speeding away. It all depends on what you measure yourself against, as long as there is no absolute rest frame for this universe. And all experiments I know of agree on that one. There is no 'absolute motion', unless we're referring to accelerations which are provable, locally.

(And again we see that word, 'locally' :)

On the other tentacle, maybe there is a definition of the Higg that consider relativity. I would like to see it.

It also states that "To remove the need for fine-tuning and still answer the Higgs-mass question, physicists have suggested extensions of the Standard Model, the most popular of which is supersymmetry. This theory proposes a heavier superparticle, or "sparticle," for every particle in the Standard Model. Sparticles would then cancel out the effect of the virtual particles in the vacuum, bringing down the Higgs mass and removing the need for any fine-tuning."

But "Ethan Siegel from SB calls for shutting down the LHC (of course he cannot openly do so). He writes that the discovery of the Higgs boson is

    … a nightmare scenario for everything else, including supersymmetry, extra dimensions, and string theory. Because finding the standard model Higgs at this energy means that there’s no need for any of those things. A Higgs at 125 GeV and nothing else at the LHC, totally consistent with the standard model, mean that if supersymmetry exists, it needs to be at such a high energy that it no longer solves the problem it was designed to solve!


He means the Hierarchy problem, and he is basically saying, though he cannot dare to actually say it (He may officially deny this interpretation), that with the Higgs, everything of interest that may still be out there is beyond the reach of the Large Hype Constructor (LHC), so we may as well scrap it!"

From http://www.science20.com/alpha_meme/physicists_demand_lhc_shut_down_after_higgs_and_higgs_nonsense-91748

Now, this doesn't state that there can't be other models than the Standard model though. But it do seem to state that they also will have to fit what the standard model describes. And there we now see a Higg particle, or 'field', with virtual photons just as real as our normal photons.

The point is that I can accept it proving inertia, at least it seems to be possible. But if it is so, then that, to my thoughts, goes against Einsteins definition of inertia in a constant uniform acceleration becoming 'gravity', as described through the equivalence principle? And that one isn't wrong, too many experiments proving it.
=

you might say I'm of two minds, every time I think of a higgs particle, or any 'field', for that sake.

or we have to redefine gravity? One type relating to rest-mass, another relating to Higgs bosons with 'real motions', also forced to add a sub category, equivalent to a rest-mass as defined from the equivalence principle?

I don't know, but hey, that's no surprise :)

Actually, assuming that the Higgs would define all types of mass. Then I also think I will have to assume that we have found 'the gold standard' for absolute motion? Which then probably should annihilate relativity? At least major parts of it.

Not sure on this one though :)
Will have to think it out.

It's like everything else the Higgs. You have to wait a while and try to see what people mean after the hype has gone away. Luboš Motl has this to say about it "The Higgs boson is a particular particle – state in the Hilbert space – in a correct quantum mechanical theory describing Nature. I mean the Standard Model or its extensions. Any discussion of the Higgs boson would be totally impossible without quantum mechanics. All properties of the Higgs boson crucially depend on principles and special effects of quantum mechanics.

The Higgs boson is a particle associated with the Higgs field. To see the emergence of particles from fields, one has to discuss physics at the level of quantum mechanics; see the previous point. However, even in classical physics, one may add the Higgs field to the general theory of relativity, much like the electromagnetic fields. The Higgs field is a source of gravity and other things. But it's just "another added player"; the main field in the general theory of relativity is the metric tensor, i.e. the spacetime geometry, not the Higgs field." Then he goes on to discuss string theory http://physics.stackexchange.com/questions/31897/whats-next-after-higgs-boson-discovery

Another pretty good explanation to why a Higgs is expected http://www.scientificamerican.com/article/what-exactly-is-the-higgs/

But I think the most honest one is http://hyperphysics.phy-astr.gsu.edu/hbase/forces/higgs.html
=

So, if you now still feel suspicious to this idea, what more can you look at? Well, it presumes 'regimes', doesn't it? It goes out from temperatures. And a 'container' of it, that inflated. I do not doubt a inflation, or expansion as defined from a inside of a universe. But I've still to understand the rest of it.

how do you define a temperature to a photon universe?

how do you define its ability to create rest mass that doesn't revert into photons again, spontaneously. It's also called spontaneous pair production, and presumed to be able to happen now too, although reverting.

how could it be hot?

and what do you mean by it existing in some 'tight spot' initially?
=

I would call those questionable.

It's not that we don't find regimes, and symmetry breaking, now. But what about those initial parameters?

you can't work it out from using matter/radiation, and then back track. It's not a given that what we see now was the initial state, meaning that without rest mass I would expect you to need a different physics approach to explain it.

and what about this 'tight spot'. Doesn't fit the definition of a expanding universe to well, does it? assuming that it expands equivalently at all positions, gravity acting as 'buoys'. Looking at it from locality, all 'spots' you go out from, to then back track in time to some specified initial location, are as plausible. There is no 'initial tight spot' in the usual meaning that starts it. Because you can pick any position you like in this universe to backtrack from, and assuming you like the concept of a 'container universe' you should have a logical fallacy if you then want to define the time wise 'tight spot' to where ever you 'end up'. You have to think it out for yourself, to see what I mean, but it's worth the trouble I think.

And that's the fallacy to me. This preconception of a container. It seems to pop up everywhere in the presumptions. You can build a very nice logic from it, if you never question your basics.

You see, if you want a very high temperature, if you want a 'tight spot' in where it happens, then I think you want a container. But the container we define is a logic container, it's not a physical one, as having touchable, measurable, walls limiting it.

Easier to see perhaps if you understand what I mean by that you can move anywhere in this universe, to the furthest edges of its visibility. and still find a exactly same view as you do from here, with stars existing all around you to the time wise and visible edge of the universe. There is no center.

It's really 'infinite'. It has to be, if inflation and expansion is correct.

Now, this is my view of it, and it builds from locality. You want another, I would say you also want a container universe, and with it, your tight spot. but that one is a logical fallacy.
