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.
Kedar JoshiIf God were to exist for the entire humanity, he would be profoundly vile, as he allows the existence of unfathomable sin, stupidity, madness, and misery for no reason than his own despicable enjoyment. God exists though, not for all humanity, but for a one chosen man - a philosopher - who is bound to answer the greatest philosophical question, the question about the nature of the questioner's existence, which progressively quenches the divine vanity.
