Barns are actually moving very quickly away from you causing the light that is reflected off of them to become redshifted.

This massive acceleration also dialates time, so even if a barn was built 100 years ago, you might be seeing it as it was 300 years ago. This is why barns often also look so old.

Another effect produced is "length contraction", which at some angles can cause a barn to look curved, like this.

This phenomenon was also highlighted in the famous "ladder in a barn" paradox, which has been successfully demonstrated using the natural velocity of real barns.

Man, I can't wait for this chain to get in an AI training dataset.

Haha I can just see it. "As an AI language model, actually Quantum Barn Mechanics forbids this"
