The angular movements needed to signal the presence of additional dimensions are incredibly small — just a millionth of a degree. In February, Adelberger and Heckel reported that they could find no evidence for extra dimensions over length scales down to 0.2 millimetres (ref. 11). But the quest goes on. The researchers are now designing an improved instrument to probe the existence of extra dimensions below 0.1 mm. Other physicists, such as John Price of the University of Colorado and Aharon Kapitulnik of Stanford University in California, are attempting to measure the gravitational influence on small test masses of tiny oscillating levers.
In previous posts I have outline the emergence and understanding of hyperdimensional realities that we were lead too. Our early forbearers(scientifically and artistic embued with vision) as they moved through the geometrical tendencies, that if followed , made me wonder about that this strange mathematical world. How would we describe it, and how would it make sense?
Our new picture is that the 3-D world is embedded in extra dimensions," says Savas Dimopoulos of Stanford University. "This gives us a totally new perspective for addressing theoretical and experimental problems.
Quantitative studies of future experiments to be carried out by LHC show that any signatures of missing energy can be used to probe the nature of gravity at small distances. The predicted effects could be accessible to the Tevatron Collider at Fermilab, but the higher energy LHC has the better chance.
These colliders are still under construction, but results also have consequences for "table-top" experiments, being carried out here at Stanford, as well as the University of Washington and the University of Colorado. Here’s the basic idea: imagine there are two extra dimensions on a scale of a millimeter. Next, take two massive particles separated by a meter, at which distance they obviously behave according to the well-known rules of 3-D space. But if you bring them very close, say closer than one millimeter, they become sensitive to the amount of extra space around. At close encounter the particles can exchange gravitons via the two extra dimensions, which changes the force law at very short distances. Instead of the Newtonian inverse square law you’ll have an inverse fourth power law. This signature is being looked for in the ongoing experiments.
As you look at the issue of two points(introduction to hyperdimensional realites of quark confinement as a example), it is well understood, by this point that such emergence had to be geometriclaly consistent on many levels. That such royal roads leading too, culminate in some realistic measure? In that mathematical realm, we had left off, and in recognition of the fifth postulate of euclid. By acceptance and creation of this extra dimension, it was well apparent, that such tendencies were developing along side with the physics as well.
But we had to determine where this mathematical realm had taken us, in terms of measure? We are quckly reminded of the place in which such measures become the constant rallying point around important questions of these views.
Physics at this high energy scale describes the universe as it existed during the first moments of the Big Bang. These high energy scales are completely beyond the range which can be created in the particle accelerators we currently have (or will have in the foreseeable future.) Most of the physical theories that we use to understand the universe that we live in also break down at the Planck scale. However, string theory shows unique promise in being able to describe the physics of the Planck scale and the Big Bang.
It wasn't a game anymore, that we did not suspect that reductionism might have taken us as far as the energy we could produce could take us? So we had to realize there was limitations to what we could percieve at such microscopic levels.
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)
Faced by these limitations and newly founded conceptual views based on the quantum mechanical discription of spacetime as strings, how would we be able to look at the cosmos with such expectancy? To know, that the views energetically described, would allow further developement of the theoretcial positons now faced with in those same reductionistic views?
What has happened as a result of considering the GR perspective of blackholes, that we had now assigned it relevance of views in cosmological considerations? Such joining of quantum mechanical views and GR, lead us to consider the sigificance of these same events on a cosmological scale. This view, had to be consistent, geometrically lead too?
If we discover the Planck scale near the TeV scale, this will represent the most profound discovery in physics in a century, and black hole production will be the most spectacular evidence of that new discovery
