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 ...
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.
A parallel universe, also known as an alternative universe, parallel world, parallel dimension, alternative 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".
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
Brian Greene talks about The Hidden Reality on Bookbits radio. The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos is a book by Brian Greene published in 2011 which explores the concept of the multiverse and the possibility of parallel universes. It has been nominated for the Royal Society Winton Prize for Science Books for 2012.
Alternate reality (or Alternative reality, UK English) often refers to parallel universes in fiction, a self-contained separate world, universe or reality coexisting with the real world, which is used as a recurring plot point or setting used in fantasy and science fiction. Alternate reality may also refer to:
Hugh Everett's many-worlds interpretation of quantum physics, "The first and most important of the four strands".; Karl Popper's epistemology, especially its anti-inductivism and its requiring a realist (non-instrumental) interpretation of scientific theories, and its emphasis on taking seriously those bold conjectures that resist being falsified.
Penrose's idea is inspired by quantum gravity because it uses both the physical constants and .It is an alternative to the Copenhagen interpretation which posits that superposition fails when an observation is made (but that it is non-objective in nature), and the many-worlds interpretation, which states that alternative outcomes of a superposition are equally "real," while their mutual ...
