A common feature of all four multiverse levels is that the simplest and arguably most elegant theory involves parallel universes by default. To deny the existence of those universes, one needs to complicate the theory by adding experimentally unsupported processes and ad hoc postulates: finite space, wave function collapse and ontological ...
Parallel universes in fiction, a hypothetical self-contained plane of existence, co-existing with one's own Alternate history , a genre of fiction in which historical events differ from reality Alternative universe (fan fiction) , fiction by fan authors that departs from the fictional universe of the source work
A parallel universe, also known as an alternate universe, parallel world, parallel dimension, alternate reality, or alternative dimension, is a hypothetical universe co-existing with one's own, typically distinct in some way. [1] The sum of all potential parallel universes that constitute reality is often called the "multiverse".
The quantum-mechanical "Schrödinger's cat" paradox according to the many-worlds interpretation.In this interpretation, every quantum event is a branch point; the cat is both alive and dead, even before the box is opened, but the "alive" and "dead" cats are in different branches of the multiverse, both of which are equally real, but which do not interact with each other.
Parallel evolution is the similar development of a trait in distinct species that are not closely related, but share a similar original trait in response to similar evolutionary pressure. [ 1 ] [ 2 ] Parallel vs. convergent evolution
Parallelism is a theory which is related to dualism and which suggests that although there is a correlation between mental and physical events there is not any causal relationship. The body and mind do not interact with each other but simply operate independently of each other, in parallel , and there happens to be a correspondence between the ...
Multiple independent timeframes, in which time passes at different rates, have long been a feature of stories. [15] Fantasy writers such as J. R. R. Tolkien and C. S. Lewis have made use of these and other multiple time dimensions, such as those proposed by Dunne, in some of their most well-known stories. [15]
This postulate does not specifically talk about parallel lines; [1] it is only a postulate related to parallelism. Euclid gave the definition of parallel lines in Book I, Definition 23 [2] just before the five postulates. [3] Euclidean geometry is the study of geometry that satisfies all of Euclid's axioms, including the parallel postulate.
