take 2 Greetings, Universe. [in acknowledgement (summary)] Yes, if you created a simulation of agents with deterministic decision making processes, you could let these agents travel through time, by creating and destroying them at planned points at a time gateway, for example. You would need to plan the entire history of their decisions, in the simulation. If you were able to create and destroy entire living beings, you could also create an entire planet that functioned like this. But it would require controlling the future of the planet in a very precise manner. In the real world of our hearts, we can take action on unpredictable randomness. We do not know the future of our particles enough to do that without harshly forcing the separation of our paths from what we need to do to protect our realities, and losing our free will. We need to be able to always make decisions based on our needs and our observations, to be alive and free.
