| Event: A change of state. The event itself has no duration, otherwise the beginning and the end of the event would have to have their own duration or the beginning and the end of an event in turn would be independent events. See also regress, process, flux, change, states._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Albert Einstein on Events - Dictionary of Arguments
Kanitscheider I 164 Event/General Theory of Relativity/Kanitscheider: every event is a point in four-dimensional space-time that can be described independently of all conceptual constructions such as vector bases and coordinate systems. Space-time/Einstein: somewhere between 10-15 and 10-33 cm the smooth manifold image of space-time breaks down. >Spacetime/Einstein, >Gravitation/Einstein, >Covariance/Einstein. Kanitscheider I 166/167 Def light cone/Kanitscheider: shows the character of Einstein's gravitational theory well: if we pick out a point e in space-time, it represents a physical event. The cone of light from e is then the story of a spherical flash of light that converges inward towards e and then diverges outward again from e. The cone of light reflects the local causal structure of the Relativity Theory. All allowed processes are represented by world lines lying inside or at most (in the case of photons and neutrinos) on the mantle of the cone. All events in the past cone can affect e and all in the future cone can be affected by e. The gravitation-free space-time of the Secial Relativity (matter-free universe) can be distinguished from the generally relativistic space-times filled with gravitational fields by the local light cone structure. In the SR (without matter) the cones are all arranged the same. In the General Relativity (with matter) they are inclined according to the strength of acting gravitational fields. (Effect on the causal structure and time by the gravitation of matter). >Special Relativity._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
