The person can be seen … WebWhen traveling speeds in the relativistic regime, distance is contracted by a factor one over "gamma." This gamma factor is equal to 1/sqrt (1-v^2/c^2), where "v" is the speed at which you are traveling, and c is the speed of light. Since you're traveling at 99% the speed of light, we have v/c = 0.99.

According to the special theory of relativity, c is the upper limit for … See more The speed of light in vacuum is usually denoted by a lowercase c, for "constant" or the Latin celeritas (meaning 'swiftness, celerity'). In 1856, Wilhelm Eduard Weber and Rudolf Kohlrausch had used c for a different constant … See more In classical physics, light is described as a type of electromagnetic wave. The classical behaviour of the electromagnetic field is described by Maxwell's equations, which predict that … See more There are different ways to determine the value of c. One way is to measure the actual speed at which light waves propagate, which can be done in various astronomical and Earth-based setups. However, it is also possible to determine c from other physical … See more The speed at which light waves propagate in vacuum is independent both of the motion of the wave source and of the inertial frame of reference See more There are situations in which it may seem that matter, energy, or information-carrying signal travels at speeds greater than c, but they do not. For example, as is discussed in the propagation of light in a medium section below, many wave velocities can exceed c. The See more The speed of light is of relevance to communications: the one-way and round-trip delay time are greater than zero. This applies from small to astronomical scales. On the other hand, some techniques depend on the finite speed of light, for example in distance … See more Until the early modern period, it was not known whether light travelled instantaneously or at a very fast finite speed. The first … See more
