I wasn't sure if I wanted to include this last time, I wish I had:
We are software that can manipulate the computer. It is like AI-"software"
in a computer that has hands and may be able to upgrade its own memory.

Well we would use some of natures tools that can interact with the topology
of space in a way we would like. For that matter, masses do interact with
the topology of space, all we may have to do is put them in the right

I assumed the underlying structure of space time interacts with space-time.
(If it didn't there was little use of mentioning it.)
I also assumed that interaction was in two ways: spacetime is influenced by
the underlying structure, and the underlying structure is influenced by the
presence of spacetime.
So if spacetime changes, by our influence (Eg. placing matter in a special
configuration) than we can manipulate the underlying structure.
