A related concern, issue: Write a program to simulate the whole universe in full and fine detail. We would likely do this work in time steps, i.e., some version of discrete time. So, in the simulation there would be a timing, time synchronization, etc. issue: In simple terms would have to update the whole universe, the whole state, FULLY at each single step before could start the next step. Or if don't write just one program, and instead have some string theory where everything is made of elementary strings, each string has its own clock, supply of energy, momentum, charge, mass, etc. That's a lot of clocks and makes the strings not very elementary.
