MULTIVERSE
MULTIVERSE AND THE PHILOSOPHY IN WESTERN THOUGHT
Discussions about the multiverse had been discussed on philosophical platforms before they became a topic of interest in the field of physics. The earliest clues on the subject are found in two ancient Greek philosophies: the Atomists and the Stoics whose philosophy dates to the fifth century B.C.
Unlike the Stoics who believe in the universe conversion on its own, the Atomists argued that “the atomic collisions also give rise to an endless number of other, parallel worlds less perfect than our own.”
Remnants of the idea were also already visible in the work of German philosopher Arthur Schopenhauer, who turns Leibniz’s argument for “the best of all possible worlds” on its head by proposing that we instead live in He wrote as “Now this world is arranged as it had to be if it were to be capable of continuing with great difficulty to exist; if it were even a little worse, it would be no longer capable of continuing to exist.”
MULTIVERSE AND THE PHILOSOPHY IN EASTERN THOUGHT
In the other part of the ancient world around 100 A.D., Early Buddhist philosophers, were trying to explain a cosmology of cause that our universe is one of many multiverses, each experiencing its own endless cycles of creation and destruction. They sought to describe a cosmology of causation that our world is one of many parallel worlds, each which undergoes its own infinite cycle of creation and destruction.
This concept is visualized in Buddhist architecture. The Chaoyang North Pagoda, also constructed by the Huayan school, has thirteen stories. On the base of the Pagoda which has thirteen stories are two small reliefs of itself and these two have imagined smaller reliefs of itself, and so on, seemingly forever. This reflects the Buddhist cosmology of the multiverse.
“There are innumerable universes besides this one, and although they are unlimitedly large, they move about like atoms in You. Therefore You are called limitless.”
‘The Buddhist’.
MULTIVERSE AND THE VARIOUS THEORIES IN PHYSICS
Physical theories, which continue as a process of philosophical discussions, are generally shaped within the framework of various significant theorists.
Kopenhagen Interpretation by Bohr is the expression of both situations of the cat-box , that is, whether the cat’s being dead or alive, are valid and real at the same time until you opened the box.
However, it is the presence of an observer that concludes which situation will occur. As soon one makes an observation ,i.e., open and look, one of two situations will become real.
In the Schrödinger version, there are infinite identical universes in identical cat experiments in infinite universes.
These universes are identical up to the point where the box is opened hence the subsequent histories may be correspondingly different.
In the Everett version of the cat-box experiment, there is a single cat up to the point where one opens the box, then the entire universe splits in two branches resulting respectively many universes.
MULTIVERSE AND THE DECOHERENCE PROCESS
However, Everett stated that since no observer will ever be aware of the existence of other worlds, claiming that the other universes cannot exist since we cannot see them is no different from claiming that the Earth cannot orbit the Sun because one cannot sense the motion.
These two branches are separated from each other. At this point, one of the possibilities can no longer interact with the other possibilities. This is what we call the process that causes this decoherence. In other words, taking the environment as a part of quantum systems makes it possible for the universe itself to split into new branches with each observation. We resume as if the other possibility had never happened but in the other universe that was created at that time of observation, (that we are not even aware of) the opposite case has occurred. That universe and the counterparts’ are as real as ours. This approach to quantum universes that branch out with each new interaction is called the Multiverse Theory.
BUBBLE THEORY
The most developed model of the multiverse that is named as “Bubble Theory” is based on the chaotic inflation idea of the multiverse of proliferating space-time. In the inflationary model, during the first tiny fraction of a second after the universe appears it happened the fast and exponential increased in size by many orders of magnitude.Vilenkin discovered that inflation starts it never ends with new universes being created all the time, from the mathematics of the inflation model.
In this theory, some parts of space-time expanded faster than others. This created “bubbles” of space times. During this rapidly expanding, the constants of the formation of universes in each bubble were formed in different combinations.
Other universes are in principle observable and this adequate to keep them in the field of science.
