Hi everyone,

It has been a while since I came on here. Busy with my new job and getting used to living in a big city on my own. I have a question that is making my head hurt and can only be answered by some big physics/maths brain:

If you had a computer that was made out of all the material in the universe, and then you used it to simulate the current operating state of it’s self (which is recursive) how much slower would the last calculation be compared to the real world calculation? What would be the absolute propagation of information?? HUH?! HUH!!!!

Just as an example forget the fact that it goes on forever since a new simulation loading up changes the state of the machine so it loads another etc.

For the first few iterations, how much behind or slower would the program be? I'm thinking someone has done the maths for this since there are huge tomes on computational theory. But since we are talking about the whole universe here, what is the physical limit of the states we could use for calculation?

I am talking about the whole universe so I want to know about the actual information propagating across the universe to. So that’s propagation time in the real world. Which must mean that an instructions starts before the first one has finished??? And then the simulation is going to be behind because it can’t compute the same amount as the original computer otherwise you are getting a free lunch.

Really looking forward to someone helping me with this one.

Is it even possible? Would it be infinite after the first level? Since you don’t have enough virtual states to represent all the ones in the universe. You need to use some sort of algorithm to cycle through them. Since that’s likely to be slower than the movement of the information in the universe just to represent the simulation. Before you start you need to start again?

This problem is to hard for me [xx(]

wOw the world spins?
