  2. Causality (physics) - Wikipedia

    en.wikipedia.org/wiki/Causality_(physics)

    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 ...

  3. Causal structure - Wikipedia

    en.wikipedia.org/wiki/Causal_structure

    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.

  4. Causal contact - Wikipedia

    en.wikipedia.org/wiki/Causal_contact

    The only objects not in causal contact are those for which there is no event in the history of the universe that could have sent a beam of light to both. For example, if the universe were not expanding and had existed for 10 billion years, anything more than 20 billion light-years away from the earth would not be in causal contact with it.

  5. Causality - Wikipedia

    en.wikipedia.org/wiki/Causality

    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]

  6. Causal system - Wikipedia

    en.wikipedia.org/wiki/Causal_system

    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 ...

  7. Causal sets - Wikipedia

    en.wikipedia.org/wiki/Causal_sets

    The best model for dynamics at the moment is a classical model in which elements are added according to probabilities. This model, due to David Rideout and Rafael Sorkin, is known as classical sequential growth (CSG) dynamics. [10] The classical sequential growth model is a way to generate causal sets by adding new elements one after another.

    Trump advisers and potential nominees have also discussed plans to either combine or otherwise restructure the main federal bank regulators: the FDIC, OCC and the Federal Reserve, the WSJ report ...

  9. Bond graph - Wikipedia

    en.wikipedia.org/wiki/Bond_graph

    The other feature is the "causality". This is a vertical bar placed on only one end of the bond. It is not arbitrary. As described below, there are rules for assigning the proper causality to a given port, and rules for the precedence among ports. Causality explains the mathematical relationship between effort and flow.
