Quantum cosmology is an attempt within modern scientific physics to formulate a complete quantum theory of the Universe.
Particle physics and Einstein’s theory of relativity provides the most common descriptions of how the world works, but it is also believed that there are principles which remain mysterious. The aim of this theory is to provide answers to some of these questions. This approach tries to answer several open issues of modern classical physics, especially those relating to the early stages of the cosmos.
Most of what we know about the cosmos comes from quantum mechanics, with nearly all of it being formulated on the basis of special relativity.
These laws state that energy, matter, and time are in a state of constant flux. These theories have been in dispute for decades, since the early 20th century, when they were first applied to quantum mechanics and Planck’s clock. A controversy which has lasted decades also followed the first description of a unified field theory, leading to what is today known as the Strong Nuclear Force. P
article physicists have also had an issue with dark matter, which has been suggested as a natural particle by Albert Einstein’s predictions. There is also much disagreement as to whether the universe is made of a definite variety of matter, or consists of a variety of very tiny “flavors”.
Quantum cosmology attempts to merge all of these differing theories into one.
One of its biggest issues is the problem posed by Einstein’s theory of relativity, namely that time and space are interchangeable. Quantum mechanics offers no guarantee as to what the exact properties of time and space actually are. Theories of general relativity still offer the best way to understand the relationship between quantum mechanics and the properties of the natural world.
The most influential part of quantum cosmology deals with the Standard Model of particle physics.
This model postulates the existence of a vacuum state, where nothing except for energy and some other matter could exist. There are some models that attempt to make predictions about the formation of the initial conditions of the big bang. However, there are many problems with this theory, namely that it doesn’t have a well-defined model.
In order to construct the theory of quantum cosmology in a useful manner, it is necessary to have a good understanding of quantum mechanics, including what it’s all about.
This is not as simple as it sounds. Quantum mechanics is made up of three main areas of study, including the strong and weak nuclear force, quantum electrodynamics, and general relativity. It is believed that in addition to these main areas, new ones have been discovered that are currently under development. Among these are the field of high energy physics, the study of supersymmetry, and the search for the ultimate number theory.
Quantum cosmology proposes that our universe is structured according to a set of rules.
These are not, however, inconsistent with each other, and many experts feel that the theories can be unified. Most significantly, the laws that describe how the big bang occurred also explain why the universe is filled with dark matter, which we know does not have any “position.” Theories suggest that these irregularities give birth to alternate universes that existed prior to ours. Since these other universes do not have the same laws as our own, they too can produce parallel universes similar to ours, but without the same laws.
Quantum cosmology can be applied to quantum mechanics in a way that will help us understand the relationship between the subatomic level and the big bang.
Among the many challenges that lay ahead of researchers is the challenge of trying to actually measure some of these phenomena. With the advent of compact satellites, the ability to observe space close to the ground has improved considerably, and a variety of communication technologies, including microwaves, are making it possible to study the far away phenomenon using the instruments available. Theoretically, a minisuperspace may exist beyond our comprehension, and while not yet available on the ground, scientists are only too aware of its potential.
It is in this way that Quantum cosmology attempts to deal with the problem of creation through time, and it also deals with the problem of evolution.
Theory indicates that all living things share a common ancestry, and were once one. From there, development via the genealogical process, mutation via Selection, and adaptation via natural selection, are all plausible biological mechanisms, with each having a hand in shaping the characteristics of life on Earth. In a way, then, understanding how we came to be can go beyond knowing what “got here,” and talk about how all of the different species on Earth are related, and evolved over time in relation to their environment.
