The Theories Of Nuclear Physics

This field of education looks into the strong force nature by using theory to study a subject known as Quantum Chromodynamics otherwise known as theoretical nuclear physics. This theory differs from the theory of quantum electromagnetism because it holds that the particles being studied hold to a different theory known as asymptomatic freedom. This is defined as the particles interacting with each other more weakly when they are probed at higher and higher temperatures and/or speeds.

One aspect of asymptomatic freedom which scientists have been studying is a concept which holds that at a certain temperature, the particles will interact with each other so weakly that no longer actually move within the traditional confines of molecular nuclei. The scientists have used highly-sophisticated computer simulations to replicate these actions and have reliably determined that this temperature is approximately 2 trillion Kelvin. Anything above this stated temperature morphs the particles into a completely different state of matter known as quark-gluon plasma. This speed necessitates the need for relativistic hydrodynamics.

These investigations have been carried out using ultra-modern equipment known as a Relativistic Heavy-Ion Collider and a Large Hadron Collider. While the data gleaned from this equipment is considered experimental, the liquid that the particles become in this matter of state is considered very good liquid. The liquid holds a very low viscosity. The energy that these experiments require is incredibly large, which also means that any molecules within this new found liquid state of matter are also moving at the speed of light.

Sometimes these studies also refer to neutron stars because of their high densities. In terms of molecular movements, high densities are very similar to high temperatures. Scientists are curious to find out if neutron stars have quark matter dwelling within their centers. Some suggest that the answer is not that far away.
