To me, while it is not more scientific, it is a lot more complex. The weave is to me a literal weaving of the threads of the universe, rather like one would weave a quilt. Except this weave does not simply go over and under. It is more like a... 3D weave. But the nature of the weave determines what something is, and even a tiny shift in the weave makes it into something new. Every tiny, infinitesimal part of the weave forms the identity of the thing that it composes.

Also, you say you are a fantasy writer, but then you start talking about CO2 and O2, and changing the matter being like changing an atom. I get confused.
