From introductory QM class, my understanding is that one can consider any number of "fundamental" particles as a composite system and pretend it is a particle. When 2 fermions are considered as a single composite system/particle, it becomes a boson. When 1 fermion and 1 boson are considered together, it is a fermion. When 2 bosons are considered together, it is a boson.
So my question (that have been on my mind for a couple of months now) is that, when you considered all particles that exist in the universe, do you in the end get a fermion or a boson? Do you have an odd number of fermions in the world.
Phrased in another way, when you add up the entire angular momentum in the universe, do you get an integer spin (boson) or a fractional spin (fermion)?
Is this a valid question? Is there a fatal flaw/assumption that I made somewhere?
Thanks
