What is the graviton? Please place your definitions

  • #51
I would say a graviton is a string that vibrates in only one of our detectable dimensions plus time so it only registers as an effect, a string needs to vibrate in all 3 of our detectable dimensions plus time for it to have a detectable physical presence...

...but I don't really know enough about it

I do like bubbles though

The string graviton is the interactive mixture of right moving and left moving vibrations on a closed string (a loop).

It also helps to understand some of the archetecture that is going on, in the views being examine by string theorists.

This mode is characteristic of a spin-2 massless graviton (the particle that mediates the force of gravity). This is one of the most attractive features of string theory. It naturally and inevitably includes gravity as one of the fundamental interactions.

I see Haelfix has reached some satisfaction in his quest. He might like the bottum line here in terms of the archetecture they are using in string theory.

Part of the quest of the http://ccins.camosun.bc.ca/~jbritton/animcup.gif I think is having your coffee and eating your cake too:smile:

A Fickled Man this topologist(instantaneous actions) be...that in morphings, he decides(?)...he cannot choose to have the donut, without the coffee?:)

Alas, he has the Elixer, movement at his grasp, and he realizes that having such power, he now must create the coffee round table, and give as amulets, shape to such donuts:)

The End:)

If gravitational field lines can extend into extra dimenisons, then what can a graviton do?

From a theoretical position, this idea of quantization of gravity waves, as a way to explain the quantum geometry, must also tell us something about the very event that takes places. If energy leaks into those extra dimenisons, then correlation between gravitational collpase would reveal comparative geometries from the failure, to its transformation.

If we had put a shell around this view, how would all the events encapsulated, respond. Pelastrian views here, as you look at bubble nucleation are very interesting, since we have encapsulated the science that has lead us to this "point".

So if you have photon intersection, what would this look like if instead of Glast perceptions, we go one step further? Any thoughts here.

Would we see any evdience of the photon intersection, since those dimensions are hidden? Our views of Young's experiment might have taken on new proportions?


Imagine that such brane worlds are hidden?
The question might be then as to why and how such a development of brane world could have ever departed from GR, yet included it, in the gravitons?

The question would be that if gravitons could go through branes and exist in the bulk, then how would we use these gravitons to describe the quantum geometry in quantum gravity? If we can scale gravitons in relation to energy released from the events, then using the quantized version of these gravitatons to describe movement in the cosmo would have to be very telling.

One thing that is clear is the use of photon interaction spoken to in Glast has run into limits in regards to TEV measures. This limit in glast is 2 to 20 TEV, but the graviton must be spoken too, at about 1? Any corrections here would be appreciated.

Calabi Yau Forms off the Brane

So in these hidden dimensions we have these Calabi Yau forms that would reveal a symmetrcial realizations.

Torso figures are brought back here for consideration. What would Klien bottle Back to back symbolize?

If photons enter this Calabi Yau, how would we identified each model or select the one that speaks to the recognzition of all forms that might emerge from the brane.

These forms could only be determined if one recognizes the gravition quantization as a means to reveal the dimenisonal aspect of the Calabi Yau?

Doesn't it look like theory is now turning around going back to the zero dimension of points?

I think it is drawing our attention to a point on the brane? How shall we develope our conceptualization on the nature of the brane?

Lets just add some clarity here in terms of supersymmetry.

http://superstringtheory.com/people/gifs/jgates.jpg

On the other hand, if you take something like light, you find it’s very different, so let’s go through some thought experiments. Let’s take two flashlights, aim the two beams of the flashlights at each other and turn them on. What happens? Well, the two beams pass right through each other, nothing at all happens. Now take two water hoses and do the same thing. Now of course you see that the water starts splattering. And although that scattering is mostly electrical, even if you could turn off the electrical charges, then you’d find that the Exclusion Principle would drive the scattering.

So our world’s composed of these two major pieces. And the thing that’s really weird about our world is, like I said, stuff like us seems mostly to be fermions. The other half - energy, light, gravity, what we physicists like to call gauge fields, are all bosons. So why does our universe have this strange dichotomy, where stuff cannot pass through each other, but light and energy can? In fact, wouldn’t the world be sort of more balanced, more symmetrical, or even supersymmetrical, if there were some forms of energy that would scatter each other just the way that stuff, matter, does, and if there were some forms of matter that could pass right through each other just the way energy does?

Allais effect

Sol,

maybe look into the Allais Effect.

The Allais effect describes the unexplained increase in speed of a moving pendulum during a solar eclipse. It was first observed in 1954 by Maurice Allais, a French economist who went on to win the Nobel prize for Economics.

Many scientists dispute whether such an effect can be consistenly observed. Others believe that if such an effect does exist it can be explained by
• the seismic disturbance caused by a large number of people moving to and from a place where an eclipse is visible
• denser air cooled by the moon's shadow exerting a different gravitational pull on the pendulum
• the cooling of the Earth's crust caused by the shadow of the eclipse

However, there is growing evidence that the Allais effect does exist and it is believed by some to represent the only gross anomaly outstanding in the current scheme of physical knowledge.

http://explanation-guide.info/meaning/Allais-effect.html

If the Allais Effect exists, it must fit in the picture.

This is very interesting.

A couple of things came to mind and I would like to see if analogies might surface here that would better explain how this might appeal to a "skipping a heart beat."

• the cooling of the Earth's crust caused by the shadow of the eclipse

I mean from a perspective you would understand through rotation how the Earth warms to the sun, so you all of a sudden change this pattern. The cooling nature, would be apparent in the Earth's alteration taking place in it's strata?

I am thinking of the quantum harmonic oscillator where you would suspend the rhythmn for a brief moment?

Sort of like being suspended over a hole of anti-gravity for a "brief second?"

When the spacetime is flat, this is the apex of the pendulum. Binary rotating stars eventually close their distances,and when they do, how shall we interpret this oscillation that has come to a end? Mecuries daisey orbit paths, no longer swinging from one point to another?

If for one briefest of moment you suspend the direction of oscillation, how would one inject energy into the cosmic octave? This can be played out on many different levels?

The anomaly would amount too, an alteration/suspension in the pendulums path?

Does this make sense?

I would just like to add this link on the shell approach as it has become apparent how pelastrian approach here would topologically speak to the other layers, not only from a cosmological undertanding of events, but from the world of quantum gravity as well.

There needed to be this understanding of http://universe.gsfc.nasa.gov/images/lifecycles/cycles.jpg , so I saw how these shells would interact, on the principals of bubble nucleation. Strange what a concept can do in one's perceptions. :smile:

thanks D for considering a response here to help. I appreciate it.

Sure this makes sense to me.
To me the solar system is a holon in which the sub-sets (planets) follow a specific number of rules. Gravitation rules (branes) are basic. Extreme positions of planets have effects not only on the pendulum but also on every particle that is concerned.

Very nice Sol. Thanks. Indeed you will need to draw that extra shell. The Mama cover. ;-)

Great image indeed. Overview of the dynamics and transformations.

About that image with torus spheres (1 to 5): the understanding of the topological boundaries is key. And I see you have that key. :wink: Indeed topological changes in (i.e.) 5 will also influence 4, etc.

When one can relate to the brane collisons that was presented to us, one can get this new sense of brane worlds in the new toy model I present here.

Think for a moment about what the developing thought might have shown us in these theoretical postions, to see that graviton production has gone beyong the brane of this new toy model. If you did not understand the vacuum, and the relationship of brane world, how would you ever percieve that the graviton is something much more then what is held to these branes? :smile:

I would also say that we could encapsulate Marcus's views very easy in relation to the calculations that are being presented. You just have to know how? :smile:
