verdenline
Verdenline is a neologism used in speculative physics and narrative theory to describe the complete causal history of a world or universe, interpreted as a generalized worldline that can encompass branching histories within a multiverse framework. The term combines verden, meaning world, with line, reflecting its role as the traced path of events through spacetime and potential alternate histories.
In conventional relativity, a worldline traces the past and future of a single object through four-dimensional
Mathematically, verdenlines are discussed using state-space diagrams, causal graphs, or branching-time logics. They illustrate questions of
In fiction and thought experiments, verdenlines enable exploration of counterfactuals, fate, and the impact of choices.
Origin and usage: The term is not standard in mainstream science and is primarily used informally in
