If we have two airships going at speed 0.6c in the opposite directions. then they will be seperated at a speed higher than light.(adsbygoogle = window.adsbygoogle || []).push({});

let's name the airships , A and B

My question is , Let's say we have the two airships pull an elastic material.

take a point of the material on Airship A name it a , and a point on airship B. name it b. if they go at a speed close to light , then point a and b will be going at a speed faster than light ?

If so. then shouldn't all the points on the elastic material be going at a speed faster than light ?
