Thanks Ich. So from what I understand, even if we were able to overcome the computational burden, we do not have enough information for the initail state to generate a true map of our region. Our initial state cannot be implied from any other data that we currently have.
Do you think we will ever be able to create a simplified computer simulation of the universe using the cosmic microwave background as the initial state that would generate the true locations of galaxies or at least galaxy clusters, and then be able to find our own galaxy or galaxy cluster within...
