Universe from nothing vs Mirror Universe

[Sorcerer]

So again I had a brilliant thought, a mirror universe wich would balance out 2 sides of an equation, but it seems Sean Carroll had it first.

Considering it, the equally opposing, more simple universe from nothing seemed like a good candidate to compare.

Which one of these would you choose if you assume one is correct and the other not? Why?

My intuition says they are not mutually exclusive.

Well yes 2 halves mirrored of a whole which adds to nothing is the common point between the 2. But they both differ from there. The main difference IMO being the number of parts to the universe. However considering the mirror is 2 seperate halves, you could equate Krauss's universe as 2 combined halves. Actually making the complexity equal.
