A
Space contraction is not noticeable until objects approach the speed of light.
💡 Explanation:
The contracted length of objects moving relative to an observer with speed $v$ is given by $l'=l _0\sqrt{1-(\dfrac{v}{c})^2}$.
Hence at small speeds $v<<c$, $l'\approx l _0$, and hence the space contraction is not noticeable.
