Light cone coordinates can also be generalized to curved spacetime in general relativity. Sometimes calculations simplify using light cone coordinates. See Newman–Penrose formalism. Light cone coordinates are sometimes used to describe relativistic collisions, especially if the relative velocity is very close to the speed of light.

If using a system of units where the speed of light in vacuum is defined as exactly 1, for example if space is measured in light-seconds and time is measured in seconds, then, provided the time axis is drawn orthogonally to the spatial axes, as the cone bisects the time and space axes, it will show a slope of 45°, because light travels a ...
The past light cone is the set of all possible light paths that could reach you at that moment, whether or not any actual light shines along that path. Similarly, the future light cone is the set of all possible light paths that originate from you at that moment, whether or not you are actually shining in any particular direction.
In volumetric lighting, the light cone emitted by a light source is modeled as a transparent object and considered as a container of a "volume". As a result, light has the capability to give the effect of passing through an actual three-dimensional aerosol (e.g. fog, dust, smoke, or steam) that is inside its volume, just like in the real world.
Given an event , the light cone classifies all events in spacetime into 5 distinct categories: Events on the future light cone of . Events on the past light cone of . Events inside the future light cone of are those affected by the beam of light emitted at .
Acheron (LV-426), the planet-like moon where the film Alien and its sequel (as well as numerous other events in the Alien franchise storyline) are primarily set; Acheron Parthenopaeus, a character in the Dark-Hunter series of romance books "Acheron: Part 1" and "Acheron: Part 2", a two-part episode from the television series The Walking Dead
