In special and general relativity, a light cone (or "null cone") is the path that a flash of light, emanating from a single event (localized to a single...

more specifically Minkowski space, physicists often refer to a "light cone". A light cone represents any possible future evolution of an object given its...

The cone of light, or light reflex, is a visible phenomenon which occurs upon examination of the tympanic membrane with an otoscope. Shining light on the...

Cone cells or cones are photoreceptor cells in the retinas of vertebrates' eyes. They respond differently to light of different wavelengths, and the combination...

In physics, particularly special relativity, light-cone coordinates, introduced by Paul Dirac and also known as Dirac coordinates, are a special coordinate...

past light cone. So in timelike intervals Δct is greater than Δx, making timelike intervals positive.: 220  The region exterior to the light cone consists...

light cones from these events intersect the particle's world line. On the other hand, if the particle is accelerating, in some situations light cones...

resulting string field theories can be very different. Using light cone gauge, yields light-cone string field theories whereas using BRST quantization, one...

dimension. The units of measurement in these diagrams are taken such that the light cone at an event consists of the lines of slope plus or minus one through that...

The speed of light in vacuum, commonly denoted c, is a universal physical constant that is exactly equal to 299,792,458 metres per second (approximately...
