I’ve been reading that the idea of ‘time flow’ might be an illusion. According to some theoretical physicists time is maybe better thought of as a series of ‘instants’. On this theory, past, present and future are meaningless; all ‘instants’ exist within a block of time. ‘Now’ is a timeless instant that is recorded in memory, but as it distances from ‘now’, dissipates as it is retired to deeper recesses of the mind or is moved deeper toward the blocks periphery.
In such a perspective a loved one’s death doesn’t mean non-existence but is comparable to the existence of someone living far away, beyond communication lines. And, me blowing out candles at my 10th birthday party is just as real and in existence as me writing this right now.
As Dan Falk, in the book, In Search of Time, points out, psychologically, linguistically, we are so locked into a flowing time, block time is pretty counter-intuitive to real life experience. Still, I bet those inclined toward religious practice might kind of like the idea.
