String Cosmology – A New Horizon For the Search For the Ultimate Constant

String cosmology is a newly developed field which seeks to apply mathematically derived equations of string theory to the problem of ancient cosmology. 

Also called String Theories, this subject is an offshoot of astronomy. A related field of study known as brane cosmology also seeks to apply these mathematically derived equations to problems of ancient cosmological study. The main aim of both these fields is to test and recheck theories of cosmological principle. If these theories can be tested and proven, then this would strengthen the basic foundation of modern cosmology viz.

String theory makes use of several simple concepts like tensors, algebraic equations and others. These are formulated in a way that they allow the presence of definite and unknown dimensions. These unknown dimensions could be a combination of magnitude, R-function and Planck’s constant. The main concept of string cosmology postulates that the dimension space can be viewed as a tensor field in curved form. Using the scalar formula, the dimension space can be transformed into higher dimensional space.

According to string cosmology, the universe was in a very early stage of evolution where it was mostly composed of basic elementary particles like protons, atoms and other atoms. 

Over billions of years, the primordial sphere got populated with many other objects like stars, quarks and tachyons. However, the growth of these additional terrestrial bodies brought the presence of de-photic space-time. In order to understand what was happening around us at that time, we need to calculate the various effects of these celestial bodies on our solar system. If the calculations are accurate, we can easily visualize the behaviour of the atomic particles.

The main aim of string cosmology is to find out the answers of these questions. 

Two of the most prominent techniques used by scientists are perturbation theory and gauge theories. These theories help in explaining the way in which the structure of our planet and universe came about. For example, perturbation theory suggests that the formation of the planets and stars came about through chaotic growth or fluctuating perturbations. Gauge theory on the other hand, suggests that the distribution of matter in our solar system can be derived from the properties of the gravitational field. String theory is also in use to explain why there are no traces of intelligent life in the vicinity of the sun.

The main concepts of string cosmology are derived from quantum mechanics.

These include the idea that the universe contains a virtual dark energy that makes space taut. The virtual dark energy helps in creating a large amount of vacuum in the emptiness of the universe. This vacuum is what scientists believe is filled with several exotic subatomic particles. String equations thus help in explaining the recent observations by NASA regarding the evolution of space dust.

String theory also helps in explaining why there is no evidence of any large celestial bodies beyond our solar system. 

The lack of evidence also poses a challenge to the general theory of relativity. String equations therefore point out to the lack of a firewall in the cosmos whereby matter can be divided into separate components. The new solution to the cosmological constant problem also points to the presence of a large amount of dark energy in the universe. In order to understand inflation better scientists rely mainly on superstring theory. Superstring theory was first developed by a team of scientists led by Johnathan W. Wright in 1990.

According to the String theory, the cosmos was created at a very high degree of precision and was unblemished in its present form during the time of inflation. However, matter began to fill the cosmos after the inflationary event due to the formation of a large amount of vacuum. Since this phenomenon did not leave any trace of its after-effects, the scientists named it vacuum radiation.

String theory postulates that vacuums also have effects on other dimensions and thus can create a bridge across the universe. 

This new view of String theory is based on the assumption that gravity is controlled by the same laws that govern magnets. This is why anti de sitter solutions to problems such as anti de starting or anti de rotating vacuums can be applied to solve problems associated with large space. Apart from this, many other vacuums have been found to be important for overall stability. Thus, it can be concluded that String theory has made significant contributions to the field of Cosmology by developing new tools that help in understanding the nature of the universe.
