Creation of universes from nothing.

...by Professor Alexander Vilenkin:

Creation of universes from nothing

I wish that I could find the original paper, but here's the abstract at least:

A cosmological model is proposed in which the universe is created by quantum tunneling from literally nothing into a de Sitter space. After the tunneling, the model evolves along the lines of the inflationary scenario. This model does not have a big-bang singularity and does not require any initial or boundary conditions.

Hmmm....

Aren't "quantum tunneling" and "de Sitter space" two things which taken together are something?  All of the "something from nothing" speculations I have researched require various laws, structures or processes to first be in place in order for their nothing ==> something to occur.  They all seem quite silly, at least on this point, and appear to reduce to semantics.
