Variellen

Variellen refers to a concept found in some interpretations of quantum mechanics, particularly those that explore alternative formulations or interpretations beyond the standard Copenhagen interpretation. The term itself is not universally standardized and can appear in different contexts, often related to the idea of multiple possible realities or outcomes.

One way variellen can be understood is through the lens of the Many-Worlds Interpretation (MWI). In MWI, every quantum measurement causes the universe to split into multiple branches, with each branch representing a different possible outcome of the measurement. These branches are sometimes referred to as variellen or parallel universes. In this view, all possible outcomes of a quantum event actually occur, but in separate, non-interacting realities.

Another related concept might emerge in discussions of quantum superposition. Before a measurement, a quantum system can exist in a superposition of multiple states simultaneously. The act of measurement collapses this superposition into a single definite state, according to the Copenhagen interpretation. However, some theoretical frameworks might consider what happens to the other potential states that were part of the superposition. These unobserved or unmanifested states could be seen as existing in their own variellen.

The precise meaning and usage of "variellen" can depend heavily on the specific theoretical framework or philosophical discussion it is employed in. It is generally used to denote a distinct, alternative, or parallel possibility or reality that arises from quantum phenomena, though it is not a term found in mainstream, widely accepted quantum mechanical textbooks. The concept remains largely within the realm of theoretical exploration and philosophical debate regarding the nature of reality and quantum measurement.
