Then we need to apply astronomical numbers to neural configurations. Using the mass in a galaxy to make a computer where the logic is on the atomic scale...
10^9 stars, each with 10^57 atoms. The logic of the post is that a group of 10^7 nuerons can have a thought, and there are 10^70000000000 ways to group them. But there are 10^59 groups of this size, each operating independently, which implies 10^(7*10^69) states in a galactic brain#, but let's call it 10^10^70 to be neat and account for dark matter in the galaxy :).
There are around 125 billions galaxies in the universe. Also, we might one day find a way to create matter.
# if my logic is right, that is. I might need a bigger brain.
