Quote: we can measure distance with light only if we suppose that the velocity of light is constant for all observers

Quotation

we can also measure a length by the time it takes light to traverse it, on condition we suppose the velocity of light constant and independent of direction. ... [p. 416] [Lorentz] preferred to suppose that the velocity [of light] is the same in these different directions, but that the bodies are smaller in the one than in the other.   Google-1   Google-2

Quote: Lorentz explained the Michelson experiments by supposing the velocity of light was constant while lengths depended on direction
