Missing Energy Events

'There comes a time when the mind takes a higher plane of knowledge but can never prove how it got there. All great discoveries have involved such a leap. The important thing is not to stop questioning.'
Albert Einstein
(1879- 1955)

It is not easy for me to follow so many minds involved in the deeper intricacies of a world, that abstractually was built, to concieve of other possibilties. If it fell within the mind's capabilties to allow such ventures, then such values become developed in the mind's neurological developement?

High energy particles have extremely small wavelengths and can probe subatomic distances: high energy particle accelerators serve as supermicroscopes:

To see What?

The structure of matter

(atoms/nuclei/nucleons/quarks)



Did it see tidbits of nature, and ways, in which to explain other views of the microscopic world? What "eye" was held to the microscope(particle reductionistic further refined) and then, with such endearing qualties spoken to us, takes us on a journey well concieved and observed?



For me then to view this compact world, and reveal the dimensional attributes of something that may seem so foreign and alien in it's guise, I realize that for the mind to peer into the deeper workings of the microscopic world, we had to understand the images the we could produce, as we learn to build mathematical structures for contemplation

Dvali uses the analogy of a metallic sheet submerged in water to illustrate the principle. If one hits the sheet with a hammer, shock waves will carry away the energy in all directions. "Most of the energy will travel along the two-dimensional surface. Only at a substantial distance away from the source will the energy loss to water be appreciable," he said. "According to our picture, we are in a very similar situation. We think gravity is 'normal' because we only measure it directly at relatively short distances, but cosmic acceleration indicates leakage.
"


To further expand on this idea of Dvali's I wanted to draw attention to the principals of this leakage. Bear with me as I try to find the literature that I have accumlated, for what is spoken now has triggered my memory by selection of these words.

So the process now is to remember where these views were previously spoken about and bring them back here for a wider comprehension of the leakage and the dimensional significance implied by Dvali, of where this extra energy is going?

Hopefully we wil see other minds involved in string theory speaking on this matter, to seal what they are doing and descibing where they think this extra energy is going?

Given the dearth of knowledge about gravity in the subcentimeter range, the group is looking for any kind of deviation from expectations, not just extradimensional effects, he says. Nonetheless, the excitement about extra dimensions helps spur the group on, Price says.

If the strength of gravity takes a sharp turn upward at around 1 TeV, as the Stanford-Trieste scenario implies, an opportunity opens for testing this theory also in accelerators. Collisions at such energies could produce gravitons in large numbers, and some of these particles would immediately vanish into the extra dimensions, carrying energy with them. Experimenters would look for an unusual pattern of so-called missing energy events.

This and more subtle effects of extra dimensions could show up at existing accelerators, such as LEP and the Tevatron at Fermilab, only if the dimensions have scales nearly as big as a millimeter. The powerful LHC will greatly improve the chances for detecting missing energy events and other prominent extradimension effects.


The bold highlight of the article preceding, points to the realization and values of what the gravitons appear to be able to do. How they can take this energy with them into those extra dimensions. This is a very important insight, that must be considered, and not just shelved because the mathematics seem disjoined from reality.

The basis of the capabilties of the dimenisonal significance in regards to these topological manueverings, had to have some basis to move from, and it is this essence, that string theory acknowledges? The energy of these gravitations in a world quite capable of being grviaational discribed, can now have a foundation in which we may describe this dynamcial issues at the quantum level?

We have moved the GR considerations of D>=4 to a much more dynamical recogntion of the probabilties inherent in energy determinations and also grvaitonic condensation values withinthe blackhole.
