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 ...
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.
A Winston cone is a non-imaging light collector in the shape of an off-axis parabola of revolution [1] [2] with a reflective inner surface. It concentrates the light passing through a relatively large entrance aperture through a smaller exit aperture. [ 3 ]
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.

Most other mammals are currently thought to be dichromats, with only two types of cone (though limited trichromacy is possible at low light levels where the rods and cones are both active). [5] Most studies of carnivores, as of other mammals, reveal dichromacy ; examples include the domestic dog , the ferret , and the spotted hyena .
