zeitartigen

Zeitartig refers to a concept in theoretical physics, particularly within the framework of general relativity and quantum field theory, that deals with the nature of time. The term is not a standard or widely used technical term in physics literature but can be understood to describe phenomena or theories that are "time-like" or behave in a manner analogous to time.

In the context of spacetime, events are often classified as timelike, spacelike, or lightlike based on the causal relationship between them. A timelike interval between two events means that one event can causally influence the other, and a massive particle can travel between them. This is the most intuitive type of separation, as it aligns with our everyday experience of time flowing forward.

Therefore, when discussing "zeitartigen" phenomena, one might be referring to processes that are fundamentally temporal in nature, obeying the arrow of time, or exhibiting properties that are constrained by the causal structure of spacetime. It could also be used informally to contrast with concepts that are purely spatial or static. The precise meaning would heavily depend on the specific context in which the term is used, as it lacks a universally agreed-upon definition. Researchers might employ such a term to highlight the temporal aspects of a particular theoretical model or experimental observation.
