string theory

Physicist one step closer towards solution of the string theory puzzle

A physicist from the University of Colorado, Boulder is very close in solving a puzzle in the string theory which has been unsolved for more than 20 years now. 

Paul Romatschke, an associate physics professor at CU Boulder has figured out a different set of tools for what created the three-quarters dilemma. This mathematical puzzle of string theory has plagued scientists for several years. This has kept them from the realization and proof of the “Theory of everything”. The results of the study have been published in Physical Review Letters.

It may not be applicable for the regular world we see around us but it opens the possibilities for the understanding of high-level physics. The results of the study could change the ways we look at the several important domains of physics such as string theory or quantum field theory. These set of theories describe the field dynamics and the entities which permeate everything. 

Romatschke said that it would have been really great to actually understand the meaning of three-quarters however this outlook is a step towards the solution, if not the solution, and provides a suggestive picture. 

The string theory has puzzled the scientists since 1960’s. It is a theoretical framework which involves fundamental, one dimensional objects known as strings. These entities constitute the fabric of everything. It was first put forward for addressing a number of questions in fundamental physics. But from there it has been applied for studying several topics such as black holes, nuclear physics to even the origin of the universe. 

One of the biggest achievements of the string theory is the conclusion that black holes and matter are nearly the two faces of a single coin. This duality allows researchers to map several properties of matter such as pressure to the black hole properties as obtained from the general theory of relativity of Einstein. It would create the possibility of a greater mathematical exploration of the string theory. However, physicists have not been able to prove a major aspect of the string theory. 

Since the duality was discovered 20 years ago, researchers have tried to clear the roadblock with equations of increasing complexity. But they arrive at the same result always. The free energy obtained from the strong interaction is nearly three-quarters of the strength of weak coupling. 

Romatschke put the equations for space which has only two dimensions. He used equations from the previous research, as well as modern techniques of quantum field theory and he proved that a relationship exists when the matter is forced to interact from zero to infinite interaction. Calculations revealed the infinite coupling’s pressure is four-fifths of that at zero coupling. This can be a standard approach in solving puzzles of this nature. It also indicates there is a stronger relationship for space with lesser dimensions.
