...in a computer simulation.

Where do I start? I'm youngfag finishing a CS BA, thinking of going on to do an MA, but I've been obsessed with time travel for all my life. I also enjoy mathematics and theoretical physics, educated myself in both up to first year level, some modules in second year. Would an MA in those help too? I believe in the potential of quantum computers and I believe in the ever growing reality of determanism. Having these factors involved, with a background in philosophy, psychology, sociology and other human sciences, what I aim for may be quite possible, from a hypothetical point of view. Belief may not be enough but the theoretical work is there. I feel like this is somewhat a lifetimes goal for me. It's a profound feeling like I could give myself up completely to this task. I'm ready to go full volcel at this point. Alls I want is to have a conversation with my grandfather while he smoked opium. This is the object of my quest.
