Causality (physics)
In physics, causality requires the cause of an event to be in the past light cone of the result and to be ultimately reducible to fundamental interactions.
Why does Causality (physics) matter?
This principle is one of the building blocks physicists use to explain the world. Without it, a whole class of phenomena would have no mathematical description. Engineers, chemists, and astronomers all rely on it.
Background: Causality (physics)
In physics, causality requires the cause of an event to be in the past light cone of the result and to be ultimately reducible to fundamental interactions. Similarly, a cause cannot have an effect outside its future light cone.
