I have a severe problem with this entire thread!

What exactly determines the particular properties, such as charge, angular momentum, mass, etc., of this universe?

They are conserved quantities, so if they are zero now it follows that they were zero at the origin, which suggests the universe came from nothing.

Why are we assuming that the choice of what went into the zero net sum is a prior definite and constrained. The question of the universe here is not so simple that it can be represented the same way that we can note that 1 - 1 = 0. Even in arithmetic model, we have to offer within our explanations what where the summands <http://en.wiktionary.org/wiki/summands#English> that let to the sum of net zero. For example, 5 - 5 = 0, 4 - 4 = 0, etc. x - x = 0. What is x? We cannot assume without discussion what is x!

Sure we can.  That's the advantage of mathematics, x-x=0 regardless of what
number is x.

It seems to me that this entire thread is infected with post hoc ergo propter hoc reasoning and we should reconsider exactly what is being contemplated. I suggest reading of a good book on Cosmology, such as "Principles of Physical Cosmology" by Phillip James Edwin Peebles <http://books.google.com/books/about/Principles_of_Physical_Cosmology.html?id=AmlEt6TJ6jAC>, where one finds a very nice discussion of these issues of without the nonsense of logical fallacies.

There's no logical fallacy in noting that a universe that came from nothing should have zero net energy and other conserved quantities.
```
```
Peebles book is pretty old, so it's not going to include knowledge of the CMB from WMAP and COBE or the discovery that the expansion of the universe is accelerating or the holographic principle. I'd recommend Vic Stenger's "The Comprehensible Cosmos", Sean Carroll's "From Eternity to Here", or Alex Vilenkin's "Many Worlds in One".
