Let's say the entire universe (both the parts known and unknown to us) restarted at the beginning of the new year January 1,1950 GMT.
Okay, we can't do that, but this is just a thought experiment.
For this experiment, our present universe would cease to exist, and a replacement universe would be restarted (or recreated) in the exact state the replaced universe was in at the start of the new year 1950 GMT. Lets call that restart time t0. In the replacement universe, all atomic particles, actions, human thoughts, etc. would resume in the state they were at t0.
My question is: Would random events and the butterfly affect from that restarted universe change the timeline as we now know it to have played out?
If so, what would be the nature of those random events?
This is a science question.
