Show affiliationsIn 1898 Henri Poincaré referred to the speed of light as a probable limit speed but rashly asserted it would never as such be experimentally verifiable. Moving space vehicle measurements of the cosmic limit speed, however, without assuming it equals c, were described by Coleman (2003 Eur. J. Phys. 24 301). A more elementary measurement is also possible, involving two mutually stationary vehicles with a third passing between them. A simple formula gives the limit speed in terms of signal speed c and three time intervals.
