Another essay which points out that time is a series of 'nows' and death is the last now for that person:-https://aeon.co/opinions/there-is-no-death-only-a-series-of-eternal-nows?utm_source=Aeon+Newsletter&utm_campaign=7590d0ab15-Daily_Newsletter_02_May_20165_2_2016&utm_medium=email&utm_term=0_411a82e59d-7590d0ab15-68942561-"If you try to get your hands on time,' said the physicist Julian Barbour, ‘it's always slipping through your fingers. People are sure that it's there but they can't get hold of it. Now my feeling is that they can't get hold of it because it isn't there at all.'-"He and many other physicists see each individual moment as a whole, complete and existing in its own right. We live in a succession of ‘Nows'. ‘We have the strong impression that [things] are there in definite positions relative to each other,' says Barbour. ‘[But] there are Nows, nothing more, nothing less.'-"Indeed, Einstein's colleague, John Wheeler (who popularised the word ‘black hole') also postulated that time is not a fundamental aspect of reality. In 2007, his ‘delayed-choice' experiment showed that you could retroactively influence the past by altering a particle of light, called a photon, in the present. As light passed a fork in the experimental apparatus, it had to decide whether to behave like particles or waves. Later on (after the light had already passed the fork),a scientist could turn a switch on or off. What the scientist did at that moment retroactively determined what the particle actually did at the fork in the past.-***-" Werner Heisenberg, the eminent Nobel physicist who pioneered quantum mechanics, once said: ‘Contemporary science, today more than at any previous time, has been forced by nature herself to pose again the question of the possibility of comprehending reality by mental processes.' It turns out that everything we see and experience is a whirl of information occurring in our head. We are not just objects embedded in some external matrix ticking away ‘out there'. Rather, space and time are the tools our mind uses to put it all together.-"Of course, as you're reading this, you're experiencing a ‘now'. But consider: from your great-grandmother's perspective, your nows exist in her future and her great-grandmother's nows exist in her past. The words ‘past' and ‘future' are just ideas relative to each individual observer.-***-"In short, death does not actually exist. Instead, at death, we reach the imagined border of ourselves, the wooded boundary where, in the old fairy tale, the fox and the hare say goodnight to each other. And if death and time are illusions, so too is the continuity in the connection of nows. Where, then, do we find ourselves? -***-"Einstein knew this. In 1955, when his lifelong friend Michele Besso died, he wrote: ‘Now he has departed from this strange world a little ahead of me. That means nothing. People like us, who believe in physics, know that the distinction between past, present and future is only a stubbornly persistent illusion.'"-Comment: In pure physics time is an arrow in both directions. God doesn't exist, but if He does, physics' conclusions are wrong.
