My religion is proven! Repent, all of you!

By way of explanation: once upon a long time ago I and several other students from my 500-level set theory class founded The Church of the Holy Nullity. I'm a Cardinal of the Church (members are either Cardinal or Ordinals).

Why the Nullity? Well, in the Beginning was the Null set. And the Null Set begat the universe of discourse.

More seriously, this is a very cool thing to find. I suspect that study of the large scale structure of the (physical) universe will, in the end, lead to some very significant surprises.
