Imagine a massless compressed spring with its left-hand end anchored to x=0.
Now I release the right-hand end of the spring.
Within an interval of time each part of the spring will expand a certain amount.
Thus the velocity of the spring at distance x should be proportional to x.
Is it true that the length of the spring must be limited by the fact that its right-hand end cannot travel faster than the speed of light?
