Ultra dense Plasma matterIn the physical sciences, a phase is a set of states of a macroscopic physical system that have relatively uniform chemical composition and physical properties (i.e. density, crystal structure, index of refraction, and so forth). The most familiar examples of phases are solids, liquids, and gases. Less familiar phases include: plasmas and quark-gluon plasmas; Bose-Einstein condensates and fermionic condensates; strange matter; liquid crystals; superfluids and supersolids; and the paramagnetic and ferromagnetic phases of magnetic materials.

Definition:
A state of matter in which quarks and gluons, the fundamental constituents of matter, are no longer confined within the dimensions of the nucleon, but free to move around over a volume in which a high enough temperature and/or density prevails. This type of plasma has recently, 2/2000, been observed indirectly by the European laboratory for particle physics, CERN. These plasmas result in effective quark masses which are much larger than the actual masses. Calculations for the transition temperature to this new state give values between 140 and 180 MeV. This is more than 10,000 times the nominal fusion plasma temperature of 10keV. 150 MeV is the characteristic energy of a particle in a plasma at roughly 1.5 trillion Kelvin. This corresponds to an energy density in the neighborhood of seven times that of nuclear matter. Temperatures and energy densities above these values existed in the early universe during the first few microseconds after the Big Bang.

quote:"I head the nuclear theory group at Columbia. Our work concentrates on the physics of ultra-dense nuclear matter, called the quark-gluon plasma. Current experiments at the Relativistic Heavy Ion Collider RHIC at BNL require the development of detailed parton/ hadron transport theory in order to interpret the data and to test specific signatures that can reveal the physical properties of this new state of matter. We have developed new techniques to solve ultra-relativistic non-linear Boltzmann equations and relativistic hydrodynamics to study collective flow signatures, such as elliptic transverse flow at RHIC. In addition, these transport models are used to predict pion interferometry correlations that probe the global freeze-out space-time geometry of high energy nuclear reactions. Recently we concentrate on the problem of non-abelian radiative energy loss and its application as a novel tomographic tool to study the density evolution in the expanding gluon plasma on times scales ~10^-23 sec. We predicted that high transverse momentum jets of hadrons produced in nuclear reactions should be strongly quenched by radiative energy loss induced by the high opacity of the produced plasma. This prediction has been recently confirmed by the PHENIX and STAR experiments at RHIC, and we have deduced from the quenching pattern that gluon densities about 100 times greater than in ground state nuclei have been attained in Au+Au reactions at Ecm = 200 AGeV. At such high densities matter is predicted via lattice QCD to be in the deconfined phase. We continue to refine and extend the theory of jet tomography in order to predict the quenching pattern of heavy quarks as well as high pT correlations of monojets. Another area of interest is the dynamics of baryon number transport and hyperonization at RHIC. Preliminary data provide possible evidence of novel topological gluon junction dynamics that we first tested on data at lower SPS/CERN energies."
If you need more info on plasma and cosmology let me know.
My time on the net is limited with the project at hand. So my thought will not be focused.
as for Ultra dense plasma matter.
Compact stars a full of it. In actual fact it makes up most of the universe.
At I guess, I'd venture the solution will have something to do with the discrete nature of spacetime, ie. the idea that there is actually a smallest unit of spacetime. But again, that requires quantum gravity, and we're not there yet. 
My bet is it just shrinks down to the Planck scale, since anything smaller is really meaningless. It would make black holes a weird kind of 'super-particle' (which is curious, as subatomic-scale black holes would appear to us very much like fundamental particles do, apparently).
