Of course, our entire universe might (as Hans Moravec demonstrates)
be a bloody huge simulation running inside a "resurrection machine"
designed to resurrect all _possible_ pre-singularity sapient organisms by
emulating them. (This assumes that his idea of replicating nanomachines
effectively causing a "phase change" in the nature of the universe,
expanding outwards at close to lightspeed and converting dead, dumb
matter into organised processing power is valid.)
How could we test it? Simple: build a galactic supercluster full
of Matrioshka brains and try to run a buffer-overflow attack on the
computational ultrasctructure of spacetime. I mean, assuming whatever's
down below the Planck length is computational in nature, and assuming
it's designed to save state information (that is, it's a resurrection
machine), about 10^18 MB's thinking hard at the same time might _just_ be
able to drain a large proportion of the entire universe's computational
bandwidth. Overload it enough and some interesting transient glitches
(local variations in the speed of light, curvature of spacetime, or
ratio of some fundamental forces?) might show up.
Of course, running a denial-of-service attack on the universe
might not be such a good idea ..
