I think that quantum variation would mean that the system would very,
very rapidly deviate. Let us neglect the computation aspect and the
direction of time aspect temporarily, and assume that we could initiate
a literal physical region of space to the exact conditions of earth at
some point in time. I would expect that the "possible futures" would
deviate very quickly.
Also, there doesn't seem to be much supporting the "galaxy brain"
estimate of computation. Either it is in principle possible, or not, and
speculation about what might support it is separate, and in this case
There are, possibly, theoretical limits preventing such a thing. Any
computer is going to be a physical system. It seems to me that
performing the simulation in perfect detail would require complexity
greater than the complexity of the system itself, or lesser complexity
but in slower than real-time. While "the earth" might be possible, there
will be fuzziness at the boundaries, unless one simulates the entire
