I know nothing, so this instead is my theory: The universe is a VM alike smalltalk. What you have now, is the action of the chain of actions of the past. The VM of now is done. You travel back. Arrive at the VM of the past, WITH THE STATE of the past. You mutate state. It work as expected, you die. But in the STATE of now, you are alive. When the time traveler exit the VM, the VM go nowhere. It already happened now, but ONLY "remember" the changes of IT, not of the OTHER vm. Assorted musings: For a short time, the universe get splitted(?) The STATE run on RAM, and that is why it not "push to the future" because is NOT persisted? The universe is multi-core, and time travel is possible because unused computation time that is assigned to the past VM when suddenly it get awakened? If the STATE is not persisted (to make all this work), how this make sense at all? Or it have snapshots (backup) and you load for a moment the past?
