Causality is the relationship between causes and effects. [1] [2] While causality is also a topic studied from the perspectives of philosophy and physics, it is operationalized so that causes of an event must be in the past light cone of the event and ultimately reducible to fundamental interactions. Similarly, a cause cannot have an effect ...
The idea that the output of a function at any time depends only on past and present values of input is defined by the property commonly referred to as causality. A system that has some dependence on input values from the future (in addition to possible dependence on past or current input values) is termed a non-causal or acausal system , and a ...
Causality is an influence by which one event, process, state, or object (a cause) contributes to the production of another event, process, state, or object (an effect) where the cause is at least partly responsible for the effect, and the effect is at least partly dependent on the cause. [1]
Modern version of law of universal causation is connected with Newtonian physics, but is also criticized for instance by David Hume who presents skeptical reductionist view on causality. [12] Since then his view on the concept of causality is often predominating (see Causality, After the Middle Ages). Kant answered to Hume in many aspects ...
The causality violating set is the set of points through which closed causal curves pass. The boundary of the causality violating set is a Cauchy horizon . If the Cauchy horizon is generated by closed null geodesics, then there's a redshift factor associated with each of them.
In Physics II.3 and Metaphysics V.2, Aristotle holds that there are four kinds of answers to "why" questions: [2] [5] [6] Matter The material cause of a change or movement. This is the aspect of the change or movement that is determined by the material that composes the moving or changing things.
The causal sets program is an approach to quantum gravity.Its founding principles are that spacetime is fundamentally discrete (a collection of discrete spacetime points, called the elements of the causal set) and that spacetime events are related by a partial order.
Causality was thought to be incidentally approximated by realistic selection of premises that derive the phenomenon of interest from observed starting conditions plus general laws. Still, the DN model formally permitted causally irrelevant factors. Also, derivability from observations and laws sometimes yielded absurd answers.
