Some months ago, after reading this book - Physics of the Impossible - it dawned on me the possibility that Time simply might not exist; it is an explanation for the (coherent) “evolution” of matter and everything else in our known Universe. We don’t born and die, we simply go through a pattern of changes, defined by some rules we’re yet to discover (something beyond unified theory and at a deeper level than Quantum Theory).

If we would to discover this set of rules we could then treat ‘time’ as something configurable. Go back in time would be simply to reverse the rules (for something or someone), as the future would be a simple extrapolation of the present. This means, past and future would be ‘personal’ for the one configuring it, hence, multiple instances of present would start to exist. How this would mess up with the present Universe coherence it beyond me.

All this comes back because of a book recently released, whose author, Sean Carroll, goes into a similar chain of thought, certainly providing an interesting explanation for those rules (I’m yet to read it). Who knows this might be a nice sketch of an interpretation to explain (and, in the end, destroy) it all.
