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 JoshiLife, by which I mean my life, is a great, or probably the greatest, design, from its very beginning to its end, the end that, I think, is unlikely to exist. Each and every bit of life is a part of the design. Design exists as the consequence of the ultimate questioner's vanity. And my mission is to find the most fundamental truth, which probably and exclusively involves the nature of the existence of the ultimate questioner.
