So a black hole consists of an event horizon and a singularity in the center. What about the cosmological horizon( which is also an event horizon)? Is a cosmological horizon's geometric center a singularity? I can imagine that an electron has a cosmological horizon. Yet an electron is pointlike, with mass/energy, so it somewhat seems like a singularity of sorts. Even if a cosmological horizon has at it's geometric center empty space, it has energy/momentum/something in it's field, located at that infintesimal point(which is probably a singularity since a point is lower than plank length).
