Скачать или смотреть Accelerating toward the speed of light (combined view)

A simulation of a uniform acceleration reaching 99.93% of the speed of light in 1′40″, illustrating the Doppler effect, aberration of light and time dilation.

See the description of    • Accelerating toward the speed of light   for a detailed account of what is being represented.

The upper left quadrant represents the front view (identical to the aforementioned video), the upper right quadrant represents the view to the right, the bottom right quadrant represents the rear view, and the bottom left quadrant represents the current coordinates (s = proper time in seconds; t = time as measured by fixed observers, also in seconds; z = distance traveled in light-seconds; dt/ds = γ = Lorentz factor; dz/ds = apparent speed measured as distance traveled in the fixed background over proper time; dz/dt = speed as a fraction of the speed of light).
