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 ...

Quantum mechanics wreaks even more havoc with conventional ideas of causality than some have suspected – according to a team of researchers based in Australia, with collaborators in Scotland and ...

Quantum batteries could charge more efficiently by skirting conventional rules of causality. Yuanbo Chen at the University of Tokyo and his colleagues analysed whether a particularly counterintuitive ...

Contrary to the statistician's slogan, in the quantum world, certain kinds of correlations do imply causation. New research shows that in quantum mechanics, certain kinds of observations will let you ...

Alice and Bob, the stars of so many thought experiments, are cooking dinner when mishaps ensue. Alice accidentally drops a plate; the sound startles Bob, who burns himself on the stove and cries out.

Causality is a concept deeply rooted in our understanding of the world and lies at the basis of the very notion of time. It plays an essential role in our cognition — enabling us to make predictions, ...

BREAKFAST in my house is a causal affair. The kettle boils because I have switched it on. The toast acquires its golden crust because I put it in the toaster. The butter makes its way to the table ...

Unravelling the causal mechanisms that explain observed correlations is an important problem in any field that uses statistical data. For example, a positive correlation between the damage done by a ...
