Causality operates through Markovian dynamics 5; small sets of variables at boundary conditions dictate outcomes within complex, nested systems.

The idea of a particle that races faster than light has long fascinated physicists. Known as the tachyon, it was originally ...

Challenges in establishing causality. Complexity of systems: one of the challenges in establishing causality is the complexity of systems we aim to analyze. Many phenomena, particularly in the social ...

An ad hoc committee of the National Academies of Sciences, Engineering, and Medicine will consider frameworks for integrating, documenting, and evaluating scientific evidence to assess causality of ...

While not quite a law, causality is certainly fundamental to our understanding of basic physics, which depends in part upon the idea that cause must come before effect. The paradox part of the ...

Quantum space and time Physicists have developed no-go theorems that limit quantum processes in space–time causality. (Courtesy: iStock/piranka) Physicists have developed a new theoretical framework ...

With the nature of the universe's two most elusive components up for debate, physicists have proposed a radical idea: Invisible particles called tachyons, which break causality and move faster ...
