String cosmology is a relatively new field which attempts to apply algebraic equations to the models of early cosmological science. A related field of study is string theory. String theory suggests that a universe consisting of countless parallel strings exists.
Cosmologists attempt to test this general theory by using various techniques, such as the GPS technology.
The main ideas of string cosmology are not really well understood by the layman. The primary idea is that space and time are continuous, but varying by the nature of masses. The idea is that space and time may be distorted by the interactions of matter with the rest of the environment. String theory can be tested by using a variety of techniques that involve measuring dimensions. Although these equations cannot be proven by the scientific community, they do have a number of exceptions.
String theory is combined with inflation to suggest a solution to the cosmological constant problem.
String theory postulates that the properties of a black hole are identical to the properties of a vacuum. Thus, if the holes are packed closer together, their overall volume will be smaller than the size of the smallest black hole, or zero vacuum. If the holes are farther apart, they become increasingly larger in relation to the rest of the universe until they essentially fill the entire sky.
String theory postulates that the large-scale structure of the universe is consistent over time and space. In string cosmology, the universe consists of separate domains or levels. Each domain has its own distinct geometry and energy. The domain that we are most familiar with, the surface of the earth, possesses a flat surface and gravity. The other domains are irregular and have either no gravity or a very weak one.
String theory suggests that the landscape of the universe is highly connected.
This is because the surface of the earth contains many flat surfaces. On the other hand, the walls of the universe are made of very heavy curved walls. These walls affect each other in complex equations that String theory postulates. In addition, gravity is not a constant in the interior of the earth, but is only a force that affects the rotation of rotating bodies. Therefore, the surface of the earth can be viewed as being highly connected to the interior of the universe through the landscape.
String theory postulates that the rate at which time is changing is completely random and unphysical. Therefore, it does not incorporate time into the equations that are used to determine the properties of matter. The problem with this assumption is that it renders String theory ineffective as a complete science. Since time is a non-real variable, the speed of the inflating or contracting vacuum cannot be measured using current instruments. In the String theory model, time is a virtual field and therefore cannot be measured by current means.
The problems encountered with String theory have prompted others to build their own alternative model of the physical universe called quantum mechanics.
Quantumists believe that there are no fixed boundaries in space-time. Therefore, they suggest that the landscapes we see around us are a result of fluctuations in the fabric of space-time. Because these fluctuations are quantum products, the patterns created are unphysical. However, some of these patterns do have the potential to give rise to new physics. One example is the so-called anti de sitter solutions that Einstein presented to London society in the year nineteen ninety six.
An alternative to String theory is to use the perturbative theory of space-time. This involves the idea that space and time are both constantly in a state of flux. Because of this, the speed of the particles can be measured from their position. In the last twenty five years there has been a major breakthrough in this field, with the discovery of a space probe that had been designed to search for phenomena associated with dark matter in the universe. Its primary mission was to test the predictions of String theory, but in the process of looking at space-time it was discovered to have many additional phenomena that were not predicted.
