What is a quantum theory?
Quantum theory is a way to explain the nature of matter and how it behaves atomic and even at a subatomical level. The quantum mechanics are closely related, which is a description of the mass atomic and subatomical levels. The theory assumes that all matter is made up of individual and quantifiable units. It was developed in 1900 by German physicist Max Planck. He introduced his theory to German physical society. While most of the theory still raises a major debate and some controversy, there are parts that are almost generally accepted on the basis of available evidence.
Quantum theory was used in a popular fiction to explain many different things. Popular TV shows such as "Sliders" and "Quantum Leap" have created a mass interest. He even plays a role in Dan Brown's novel "Angels and Demons" during the part explaining the existence and importance of antimatter. In most cases, see this and other fiction on one of the two main theories related to the reality of the natural world to buildtheir premises. These theories are called the interpretations of Copenhagen and the theory of many worlds.
The theory of many worlds assumes that once an object exists in any state, the universe around this object transforms into a number of parallel universes. The number of parallel universes is determined by the number of possible universes in which it is possible for this object to exist. This number cannot be known, at least because it is now with modern scientific instruments. At some point, tools that may explicitly show the principles of quantum theories may be developed.
Copenhagen interpretation of quantum theory suggests that particles cannot be assumed that it exists until it is measured. After this happens, it is anything that is measured. Although it looks like a direct design, this interpretation of quantum theory suggests that the particles are in all possible states until it is measured and specifically observed.
This is often iluDisressed by using an example known as Schrodinger's cat. If the cat is taken in a hypothetical example and thrown into a box, it is safe to assume that it is alive, at least for some time. If a bottle of cyanide throws into this box, the cat could break and kill. Or it could have been undamaged and spared the cat. As long as it is known, the Copenhagen interpretation of quantum theory would postulate that the cat is in both states, which means living and dead, at the same time.
One of the greatest critics of quantum theory is Albert Einstein. Einstein could not agree that the only particle could exist in more than one universe, as stated in the theory of many worlds. However, the physicist accepted some aspects of theory. For example, he understood that energy could exist units and proposed that not only energy but also radiation.
