This scale model of the distance from the Earth to the Moon shows the speed of light (sense 1) accurately to scale.This apparatus was used in the 1930s to measure the speed of light (sense 1).
As the subjectivespeed of light is raised within the field, objects outside will appear to red-shift, eventually becoming visible only to radio telescope antennae.
2011 September 22, Nick Collins, “Speed of light 'broken' by scientists”, inDaily Telegraph[1]:
The science world was left in shock when workers at the world's largest physics lab announced they had recorded subatomic particles travelling faster than thespeed of light – a feat that Einstein said was impossible.
In a single generation, a cell can only influence its nearest neighbours, and so thespeed of light (by analogy with the speed of light in physics) is the maximum rate at which information can propagate.
1992 August 14, David I. Bell, “Spaceships in Conway's Life (Part 1)”, incomp.theory.cell-automata[2] (Usenet):
The translated distance divided by the period is the speed of the spaceship. Since the maximum speed of propagation of a signal in Life is one cell per generation, this speed is known as c (thespeed of light). This speed is also the fastest possible growth of any finite object for a finite number of generations (think of a long line of ON cells). However, growth (or even just movement) of a finite object for an infinite time cannot occur at this speed.
