If the universe is a non-spatial computer, a 'time machine' is a program that allows a user to have the same (ontologically non-spatial) feelings or experiences that occurred or s/he merely feels to have occurred in the past, with an in-built function to have different feelings or experiences than those of the past, and thus creating a possibility to change the past or to rewrite history in a pseudo sense.
