We don't really understand time. Our experience of it as an ongoing series of events tempts a perspective of linear models, the arrow of entropy, a steady treading of moments from one to the other. When confronted with a lifetime of happenings which came together to form an undercurrent we didn't know was there, time suddenly looks a little different and it's not always easy to assimilate evidence when it makes things look very different from the way we expected them to be.

I mean, we all tread the mortal coil but while we're reading and writing and breathing and checking we have a pulse, we are in a position to do something constructive with what might happen next. We've a Multiverse to choose from in determining our next steps. Science has at least come round to unequivocally accepting that one, leaving us all very free to do the same.
