Even if every-"things" are objects, Einstein showed us we can't say much about every object in the universe, especially those which are outside our light-cone. Thus "everything in the universe" probably denotes pretty abstract things, even physically.
In the original statement, we may want to consider "everything" to be actual objects. Non-classical logic (like in constructionism) is powerful (and useful) to reason about abstract constructions: logic, maths, computing... When dealing with actual objects we can feel, classical logic looks good.
