The 22 pages that link to Light cone, each with the reason it gives.

• Special relativityRelated: Its boundaries encode the causal limit imposed by invariant light speed.

• Speed of lightBroader topic: Its boundary marks which events can be causally connected at light speed.

• Event horizonBroader topic: At the horizon, the future-directed light paths no longer lead outward to distant observers.

• SpacetimeRelated: It divides events into those that can causally affect one another and those that cannot.

• Proper timeRelated: Light cones distinguish timelike paths, along which clocks accumulate proper time, from lightlike paths.

• Minkowski spacetimeBroader topic: Its boundaries divide spacetime into causal regions for each event.

• Spacetime intervalRelated: The interval’s zero-valued separations form the light-cone boundary.

• Relativity of simultaneityRelated: It distinguishes frame-dependent timing from invariant causal order.

• Experimental filmRelated: Its collection and screenings support the circulation of films outside commercial distribution.

• Causal structureBroader topic: Its boundaries divide events into causally reachable and unreachable regions.

• Cosmological horizonBroader topic: A horizon marks the limiting edge of which events lie within an observer’s relevant light cones.

• Event (relativity)Related: It divides other events into causally reachable and unreachable regions.

• WorldlineRelated: It constrains which worldline directions are physically possible.

• Particle horizonRelated: The particle horizon is the distant boundary of the observer’s past light cone.

• Locality (physics)Related: Relativistic locality restricts causal influence to events inside or on light cones.

• Penrose diagramBroader topic: Light cones remain at 45 degrees under the usual diagram conventions.

• Spacetime diagramRelated: Its boundaries mark light paths and divide possible causal relations.

• TachyonRelated: A tachyon's path lies outside the light cone, unlike paths of ordinary massive particles.

• Curved spacetimeRelated: Spacetime geometry determines which events can causally influence one another.

• Geodesics in general relativityRelated: Null geodesics lie on the light cones defined by the spacetime metric.

• RelativityBroader topic: It expresses how light speed limits cause and effect.

• Retarded timeRelated: Its past boundary identifies events capable of influencing an observation.
