It can look dumb, but I always had this question as a kid, what physical principles would prevent this?

Latest research is suggesting that the observer from the pole's perspective sees the far door open before the near door, basically reversing the order of events. (Assuming the barn doors close briefly around to contain the pole, and then open again to let it through. The Barn sees the entire pole momentarily inside the barn with both doors closed, the pole sees itself enter the short barn, the far door closes briefly and then opens letting the front of the pole through, then the back door closes and opens as it passes through. IE: order of events can be recorded differently for each observer without breaking causality.)
