What is quantum cosmology?
Quantum cosmology is a branch of theoretical physics that attempts to understand the universe on quantum, rather than a classic scale. Although it may seem absurd to describe something as much as large as the universe through the physics industry, which usually focuses on the world of microscopic, quantum cosmology can actually help explain the main questions in the heart of the universe understanding. One of the primary objectives of quantum cosmology is to explain the state of the universe at the time of the Big Bang, because many properties of the universe can be explained if the origin of the system is understood.
In order to understand quantum cosmology, it is essential to have a basic understanding of quantum physics. While classical physics is considering an area of larger objects, such as planets, solid objects and anything that can be seen with the naked eye, quantum mechanics deals with a sphere of atomic and subatomical particles and waves. In many cases, objects on quantum are behaved according to rules that seem to be completely different PRo objects than macroscopic objects. However, some physicists believe that the behavior of larger objects corresponds to the rules of quantum mechanics; Large bodies such as the universe may be better understood if they can be described on a quantum level.
The key area of investigation in quantum cosmology is the behavior and condition of the universe just after the Big Bang. Given that questions related to the origin cannot be answered by observation, the general means of developing theories is to look at the current state of the universe and then extrapolation back into the Big Bang to find out how this process began. Ideally, the knowledge of the origin of the universe acquired by quantum cosmology will eventually allow scientists to predict with a high degree of probability the future of the Universe.
Some physics have accepted quantum cosmology because it allows the way around a huge problem created by exploring the origin of the universe with general physics. According to StephEna Hawking, among other things, began the universe as a singularity around which it is known that the laws of general physics are falling apart. In order to have the chance of a precise understanding of the conditions after the Big Bang, quantum physics may be more advantageous because it is not known that it is subject to a similar collapse near uniqueness.
Quantum cosmology is a relatively new branch of theoretical physics dating back to the mid -20th century. As such a new field, it naturally includes much more questions than answering the origin and behavior of the universe. However, this fascinating field attracted some of the brightest minds in physics, and it seems that in the upcoming centuries it is ready to allow significant discoveries.
