The Bumble Be, Mentality
So what is the Gluon that binds?:)
For introduction sake, I might have deviated from Sean Carroll's ideas about the, "what science doesn't know" and traded it for mechanical systems interpretations, and the way we can write comprehension forms from such patterns inherent?
It always comes down to the lesson of a Beautiful mind? It's struggle for freedom from the illusions that we might perpetuate. The escape from, those delusions, to concrete analysis of such systemic thought patterns within human nature. The triumph and freedom, to overcome all odds?
If we thought of Belt rotations and Greg Egan, it wouldn't be to hard to place some perspective on how Sean might have intepreted the "wing rotation of slowed photography," and said, "hey, here is this pattern, and something a string theorist could hang their hat on?"
Satisfactory conclusion to rotations, that equatively reach across and touch us like E=mc2 does, then what's the point of concluding any thoughts if this consistancy can't be accomplished? So herein lies my inexperience, and the last recursive thought of, "okay, what science doesn't know, I scream?" :) Was it emotive enough to make my point?
And so in reference to string theory work, I couldn't help but think of the rotations, waiters and table trays and such. But it also made me think of the inroads to observation of nature and flight? Wilbur and Orville Wright as well?
But looking deeper, and from what one could gain from such observations, did I miss Sean's point?
Marc D. Hauser:
We know that that kind of information is encoded in the signal because people in Denmark have created a robotic honey bee that you can plop in the middle of a colony, programmed to dance in a certain way, and the hive members will actually follow the information precisely to that location. Researchers have been able to understand the information processing system to this level, and consequently, can actually transmit it through the robot to other members of the hive.
But it's more then the honey bee mentality. It's about communications systems we use to explain? So am I going to get Sean's goat on this one, and reverberate something he does not like? :)
But we know relatively little about how the circuitry of the brain represents the consonants and vowels. The chasm between the neurosciences today and understanding representations like language is very wide. It's a delusion that we are going to get close to that any time soon. We've gotten almost nowhere in how the bee's brain represents the simplicity of the dance language. Although any good biologist, after several hours of observation, can predict accurately where the bee is going, we currently have no understanding of how the brain actually performs that computation.
So I have in essence percieved the "Bee HIve Mentality of string theory" as a underlying causation, that if held too, becomes, "how little we really know." What ha/ormonial( I like to play with words?) factor, drives that body/system?
I bet that sounds like chalk board screeching to him:) Yes I gave the anti-string/M theorist more ammunition.
I also opened the door to another thought of mine. About the uses of, "Math and the foundations." But this is just me, trying to break down the reistance to mathematical prowness, that any other mathematician might try and hide, as a model of strng theory/M intepretation.
You can't just sweep it under the rug kind of thing and say what science doesn't know. Has yet to be proved?:) Oops, I extended the board screeching to include, the extension of, and Modifications to GR. I can't help it. The power of the "force" is really string?
The Cosmological Constant and the Vacuum Energy
The cosmological constant is not “predicted” to be Planck scale, simply because, in a QFT context, it is not predicted at all. It is a renormalized coupling and can have any value whatsoever.
What is true is that, in order to achieve the observed value at low energies, the bare value (at the cutoff scale, which we might take to be the Planck scale) must be fine-tuned to enormous accuracy.
But that’s not the same thing at all as saying that the value of the cosmological constant is predicted, and that the prediction comes out wrong.
Jacques Distler has volunteered(?) for the sake of people like myself by opening the doors to clarity issues around the interrpetation of the cosmological constant.
So this leads to the second part of Sean's post that gets me to thinking about how perception might have been revealled in the dynamics scenario of Omega (w) and how we see that the background as a "energy density," can ever be seen as zero? That such a valuation would limit one to thinking that such a dynamical universe had to explain the nature of the curvature parameters beyond, what was comsologically understood?
The Friedmann equation which models the expanding universe has a parameter k called the curvature parameter which is indicative of the rate of expansion and whether or not that expansion rate is increasing or decreasing. If k=0 then the density is equal to a critical value at which the universe will expand forever at a decreasing rate. This is often referred to as the Einstein-de Sitter universe in recognition of their work in modeling it. This k=0 condition can be used to express the critical density in terms of the present value of the Hubble parameter.
For k>0 the density is high enough that the gravitational attraction will eventually stop the expansion and it will collapse backward to a "big crunch". This kind of universe is described as being a closed universe, or a gravitationally bound universe. For k<0 the universe expands forever, there not being sufficient density for gravitational attraction to stop the expansion.
So on a csomological level we get this sense of curvature and here to further exploit this understanding the means to such equations supplied for this endeavor.
Now for the vacuum to be define here in a planck scale valuation, it was not important for me, (okay maybe it is needed) to see the positive and negative effect of what and how the universe was doing at any particular stage. I always saw it as expanding, yet within the confines of the universe, it had the capability of doing galaxy dynamics, that would lead to greater intensities, expansive and contraction features, when we looked at the energy and matter cyclical valutions, in a geometrical sense, wrapped as "global" cosmological constant.
Bumble Bee Economics
See what happens when the creative juices are added to imagery and analogy gives insight from another perspectve?
