If you have a U-shaped object, and hold one of the arms and stick the bend into the nothing, does the other arm fall or does it act like it is still attached?

I assume it would fall. Given that when something is pulled out of the nothing, the part stuck into it does not reappear, in such a situation the connecting part of the object would cease to exist and split the object into two parts.
