Are there an equal number of protons and electrons in the universe?

I was thinking about ionizing atoms and such and started to wonder if there was a net charge to the universe. Whatever the obscenely large number of protons in existence is, is there the same number of electrons?

No.

While it is generally suspected that the net charge of the universe is zero, there are charged particles other than the electron and proton that can carry the charge around. As a trivial example of why there *can't* be the same number of protons and electrons, we know of processes where you collide two protons and out pops three protons and an antiproton. If the number of electrons and protons had been the same before that interaction, it's certainly not the same now.
