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 JoshiMy existence is such that "I" do not really exist. At the end of understanding so much I understand that I know nothing. I suffer for being surrounded by intense suffering and yet I'm deeply suspicious if first of all there is indeed any consciousness except me. I strive to find the artist who might have fathered this great universal art but feel myself to be too feeble to accomplish this seemingly unattainable mission. Yet I have every respect for life, and it is this sheer respect that makes me live.
