We assume the correct answer is that this is true according to Einstein's special relativity.

Jan Slowak

Pagq 146 6.5 What Lorentz contraction DOES NOT mean

"Now, just like time dilation, Lorentz contraction is often misunderstood to mean that space itself shrinks in the direction of motion in the moving frame, and consequently, spatial distances measured in the moving frame will always bi longer (since they are using a shorter ruler) than in the stationary frame.

Again, this is not true."
