This 'saturation maximum' of a photon that you are referring too.
Is that how you see it acting as a 'particle' then?
Yes; I thought of the saturated points as appearing to be particles; however; Dr. Kemp convinced me that it was the transition from zero amplitude to the maximum amplitude that would interact as a particle. According to Kemp, mass is electromagnetic change. So it is the change that makes the difference. The saturated amplitude simply gives us the quantum phenomena.

The state of energy called matter would be composed of these things locked in resonant patterns.

I'm unsure about that. There are many types of particle with different mass, different charge, and that are affected by different forces. How does that theory account for that? Does it just apply to fermions?

Does it mean that different amplitude accounts for the difference in the mass of particles? How do you get different particle types? What about spin?

To me it seems that you can't differ between the expansion pace's redshift, if it's there, and Doppler redshift?
It will be a guess, however educated it might be.

Or?
Yes; there does seem to be a problem there. In the past I've noticed that when this kind of speculation runs rampant in a previously accepted theory, it is usually the prelude to a more profound change in the theory.

Dr. Kemp and I worked out all the elementary particles as well as gravity and the strong forces. But I don't want to hijack this thread. I have a thread in the New Theories forum that would probably be more appropriate if we want to discuss this more.

In Einstein’s theory, gravity is as an attractive force so, in general relativity, the expansion should slow down depending on the density of matter and energy in spacetime. As it doesn't seem to do so, we will have to look at the possibility of other forms of energy producing a repulsive gravity.

Jack Sarfatti see that 'energy' as being 'dark energy', this apparently is allowed by General relativity, even though belonging to 'special cases'. To explain the effects of dark energy he then look at vacuum energy, as it seems mathematically equivalent to the 'cosmological constant' (Einstein 1917). The idea behind this is a so called “vacuum coherence” which then would be a inflation field in 'disguise'. And the idea behind that :) is then based on Dirac’s theory of the electron, and would then be a similar effect to how a normal metal becomes a superconductor.

http://arxiv.org/abs/gr-qc/0602022 (2006) and http://arxiv.org/abs/0902.0032 (2009)

This is kind of scary in fact :)
Reading you Chris I commented almost the same as this idea with the exception that it then might be similar to 'virtual particles' as it would give an effect without 'materialising'. Reminds me of an earlier post in where I mentioned the 'unreal' significance of 'best guesses' when done in good faith :)

Yep, spooky stuff indeed :)

The emergence of gravity as a retro-causal post-inflation macro-quantum-coherent holographic vacuum Higgs-Goldstone field

Authors: Jack Sarfatti, Creon Levit

The title is certainly an exercise in mental gymnastics :)

Edit: Maybe I should say verbal gymnastics.

I took the liberty to translate it into proper english with the help of a synonym wordbook.
It should be so much clearer now...

Original
"The emergence of gravity as a retro-causal post-inflation macro-quantum-coherent holographic vacuum Higgs-Goldstone field"

And the final definition.

"The outgrowth of solemnity as a ex post facto-causative postal service-splashiness  mega-measure-tenacious holographic vacuity Higgs-Goldstone theatre."

Did anyone notice this?

"The future de Sitter event horizon world hologram is “our past light cone at the end of time”. It can be pictured as a pixelated spherical shell of area NL P infinitely far from our detectors (in proper time) on their future light cone, with thickness L P and duration L P/c. This shell, or “screen”, has 4D volume NL P with dark energy density hc/(4DVolume Hologram Screen).

This screen projects the voxels of our accelerating expanding 3D space hologram image back from the future - indeed, back to the moment of inflation 13.7 billion years ago in what Igor Novikov calls a “globally self-consistent” strange loop in time. To summarize: The area of an observer’s future de Sitter horizon holographically determines the dark energy density seen by that observer." (2009) paper.

Gravity if faster than light. But what i understand is that matter can't travel beyond light speed. What of the matter that travels into a black hole? Aren't they traveling faster then light? Maybe in the BB gravity, being split from the other properties, was the first driving force. That would mean that if we could watch the event, materials could have been light years past us before we could even see the light. Would it then mean that light is still trying to catch up and what we see now or rather what we could measure is only 13.4 billion, visible light, years old?

I don't think I understand what this is about. Where is the hologram coming from? I must have missed that.

The hologram thing is yet another bit of weirdness dreamed up by those nice string theory chaps. Some scientists from the UK & Germany have theorised that we're doing it all wrong by looking for extra dimensions. They say that there aren't even 3 spatial dimensions and that space acts the same way as a hologram where a 2d image is made to look 3d. It is only at low energy levels that a 3-dimensional description becomes effective. Information is somehow "painted" on the 2d surface that gives the illusion of 3d.

In their 2d model gravity doesn't exist, but blackholes & gravity waves do. I don't know how that works. It's all a bit much for my poor little brain.

I like the hologram idea; that might lead to some real world advances in holography. It would be nice to have holographic TV.

That idea(s) is so very strange. If it was true we all would be nothing else than 'ideas'. All matter then would seem to become 'information'. And as some see information as constituting of 'bits' then "the fundamental particle is a bit (1 or 0) of information." http://en.wikipedia.org/wiki/Holographic_principle#Limit_on_information_density

I prefer to believe in some sort of topological feature creating what we call matter :) Also that there should be some fractal principle guiding it. and when it comes to the smallest 'bits' I'm not sure that they exist, to me it seems more as if we are living in something (spacetime) that is created as a 'topological' reason of something else. To me we are baubles of improbability ::)) created from something we can't see, as fishes may not notice water. Maybe we can 'jump out' of it to see that other 'reality'. We should really try to understand what vacuum is, as it is there we see the clearest indications of something out of 'nothing'.

You're right lightarrow; I had never before encountered the notion of a holographic universe. I have some reading to do.

Quote from: yor_on's link
The holographic principle states that the entropy of ordinary mass (not just black holes) is also proportional to surface area and not volume; that volume itself is illusory and the universe is really a hologram which is isomorphic to the information "inscribed" on the surface of its boundary.

This notion is really weird. It may take awhile for me to come to grips with it.

We think that the early Universe expanded very rapidly - known as rapid inflation - exceeding the speed of light, which the expansion of the Universe today continues to do.

How is this compatible with light being the fastest thing in the Universe?

Chris
Has the following thought ever occured to anyone else here at Naked?

Is it possible that the expanding field created by the Big Bang determines the speed of c? Many thoughts about the true nature of constants have been put forth, some insisting that c, G, ect. have remained the same since the beginning. Others question whether they are truly constant after all. I fall into the class that believe they change relative to the conditions within the universal field. If this is so, during the time of the so-called inflation, the field expanded beyond the present limit for c but because the field itself determines that limit, the speed of light was not exceeded.

That is as good an explanation as any I have seen Ethos. My own speculation is that the universe didn't and is not now expanding. The expanding model is only necessary when we need to explain spectral analysis of distant objects. I do not know what it is, but I suspect there is some explanation that does not require such cavalier trashing of the physical laws of nature.
